Definitions
- the invention relates to a motor vehicle hinge according to the preamble of the independent claim.
- EP 0 816 610 B1 shows a motor vehicle hinge, which is used for the articulated connection of a motor vehicle door to a door frame.
- the motor vehicle hinge has a first hinge half made of steel, which is fastened to the door frame of the motor vehicle door, and which is connected via a hinge pin hingedly connected to a second hinge half, which is attachable to the door.
- the hinge has a locking device, which determines the two hinge halves mutually releasably in certain pivoting angles, wherein the locking device has an approximately cylindrical sleeve which is non-rotatably connected to the hinge pin.
- the sleeve and a brake member are inserted in cavities recessed from the solid material of the first hinge half, the brake member defining preferred opening angles of the door with recesses or grooves provided on the circumference of the sleeve.
- a disadvantage of the known motor vehicle hinge is the fact that in order to achieve certain pivoting angle of the motor vehicle door, the diameter of the sleeve is sized so that that portion of the first hinge half, in which the sleeve is received, has a large radius and correspondingly far from the plane, in which the hinge half is connected to the vehicle door frame, is spaced. Since the hinge half is a one-piece steel body, numerous machining operations are necessary to produce cavities such as channels and openings which allow integration of the locking means in the hinge half.
- the hinge half absorbs due to their massive design, the forces introduced by the weight of the door and loads, but this has a high weight. In the machining of the hinge half for the creation of the cavities, a large part of the material as Span and thus as Wasted material loss. When assembling the hinge there is a risk that the sleeve is incorrectly applied to the hinge pin and thereby the recesses, which define the preferred opening angle of the vehicle door, are arranged in the wrong places. Finally, the fastening means of the first hinge half are provided clearly outside a plane normal to the abutment plane through the hinge axis, so that set by the distance undesirable moments.
- a locking device which determines the two hinge halves mutually releasably in at least certain pivot angles, comprises a non-rotatably connected to a portion of the hinge pin sleeve whose circumference is profiled so that a spring member acted upon by a brake member which cooperates with this circumference of the sleeve, different is strongly deflected and so generates a braking torque, which counteracts the opening of the door.
- the hinge half in which the locking device is arranged, is formed as a one-piece solid metal part, which is heavy and in the tough material, the cavities for the arrangement of the components of the locking device must be machined. The corresponding processing operations are time-consuming and costly. Due to the large diameter of the sleeve, it is also necessary to space the hinge axis relatively far away from the contact plane of the hinge half on the door frame, and also to form the region of the hinge half, in which the sleeve is received, correspondingly large.
- DE 10 2009 014 084 B4 describes a motor vehicle hinge, in which a first hinge half with a second hinge half by a Hinge pin is pivotally connected, wherein the hinge halves are each fastened to one of the vehicle door and door frame.
- a locking device which is arranged in one of the two hinge halves, comprises a sleeve arranged on the hinge pin, which generates a braking force for the door with a brake member which can be fed radially to the sleeve.
- the sleeve is supported on the inner circumference of a cylindrical opening with a constant radius.
- a disadvantage of the known motor vehicle hinge is on the one hand its high weight to which the hinge half made of solid material contributes with integrated locking device, in addition complicated cavities must be introduced to accommodate the locking device.
- a particular disadvantage is the large diameter of the hinge half in the area of the sleeve received therein, which not only causes a large extension of the hinge half, but also a radial projection of the hinge half in the region of the sleeve, which is undesirable.
- DE 10 2012 004 810 A1 shows a motor vehicle hinge for a side door, which has a first hinge half, which is attachable to a door, and a second hinge half, which is attachable to a door frame has. Both hinge halves are hingedly connected by a hinge pin. Both the first hinge half and the second hinge half each have a support structure made of a carbon fiber reinforced plastic and a plastic insert, which can be inserted or injected into the respectively associated support structure in a direction parallel to the axis of the hinge.
- the insert has a receptacle for a threaded bush, the support structure has an opening at the location of the receptacle for the threaded bush.
- the fixation of the insert in the support structure is effected by means of a screw which is screwed into the threaded bushing.
- the first hinge part is fastened to the body at the same time.
- the inserts can be fixed by means of a projecting rib on the respective support structure.
- the hinge pin has a corrugation at one end, so that it into a receptacle of the first hinge half can be fixed with respect to rotational movements about its radial axis.
- the other end of the hinge pin is rotatably supported in the second hinge half.
- the hinge pin stores only on the use of the second hinge half, so that the entire vertical force of the hinge pin is transmitted to the insert; Likewise, the hinge pin is only in contact with the use of the first hinge half, so that a transfer of vertical forces in the support structure takes place at best indirectly.
- the hinge halves of the hinge are made by first providing a carbon fiber reinforced support structure which is then provided with a plastic insert.
- a motor vehicle hinge according to the preamble of claim 1, comprising a first hinge half and a second hinge half, one of which is fastened to a motor vehicle door and the other to the door frame.
- the locking device has a hinge pin associated with the locking sleeve, which cooperates with a pin formed as a brake member.
- the locking sleeve is equipped with locking grooves which define holding positions, wherein the locking grooves are introduced into the completely formed with the same radius circumference of the locking sleeve as recesses.
- WO 2011 057 966 A1 describes a motor vehicle hinge in which a first hinge half and a second hinge half are each hingedly connected together via a hinge pin, wherein one hinge half is provided for attachment to a door and the other hinge half for attachment to a door frame.
- a locking device is arranged, which defines the two hinge halves mutually releasably in at least certain pivot angles.
- the locking device has a connected to the hinge pin brake member which is formed against a trained on an inner periphery with locking marks Resting segment is biased. It is the object of the invention to provide a motor vehicle hinge which is improved in dimension and weight. This object is achieved by a motor vehicle hinge with the features of the independent claim.
- a motor vehicle hinge a first hinge half attachable to one of the motor vehicle door and door frame, a second hinge half securable to the other of the motor vehicle door and door frame, a hinge pin hingedly connecting the two hinge halves, and an inboard hinge one of the two hinge halves arranged locking device, which determines the two hinge halves mutually releasably in at least certain pivoting angles, wherein the locking device comprises a hinge pin associated with the locking sleeve and cooperating with the locking brake member, wherein the locking device associated with the hinge pin locking sleeve with a radially projecting locking segment and a cooperating with a peripheral surface of the locking segment brake member, wherein the brake member is preferably radially against the outer peripheral surface of the locking segment v is biased on a spring member.
- a larger outer circumference of the locking segment is advantageously provided which allows a correspondingly better resolution for certain locking positions, without thereby increasing the overall dimensions of the locking sleeve and / or the dimensions of the locking sleeve receiving opening.
- this can be changed by replacing the locking sleeve with otherwise unchanged hinge, e.g. for different vehicle models.
- the outer circumferential surface may extend over an angular range, the maximum opening angle of the vehicle door, usually about 75 degrees 90 degrees, corresponds.
- the outer circumferential surface protrudes radially relative to the remaining circumference of the locking segment in the manner of an angular segment, whereby the boundary surfaces of the angle segment, which connect the outer peripheral surface with the sleeve part of the locking sleeve, at the same time form the stop for maximum and minimum opening angle.
- the rest of the circumference of the locking segment is in this case formed essentially as a cylindrical shell portion, which is received in a correspondingly small-sized portion of the opening of the hinge half.
- the rest of the circumference at the same time the storage in this opening is used to support the pivoting or rotational movement of the angle segment, but it is preferably provided that the entire circumference of the locking sleeve is arranged spaced from the opening, and thus possibly the abutting Limiting surfaces of the locking segment against parts of the opening come into abutment - this friction and noise and an undesirable change in braking force is avoided with changing tribological parameters.
- the angle segment which has at least a 20% larger radius than the rest of the circumference of the locking segment, a correspondingly large resolution is achieved in the region of the outer peripheral surface, wherein the opening for receiving the sleeve with the locking segment can be made smaller because the locking segment only passes over an angle that corresponds to twice the opening angle of the vehicle door, and thus is usually less than 180 degrees.
- the critical dimension namely the distance of the contact plane of the hinge half with the door frame or the motor vehicle door to the remote end, turn out smaller.
- the mass of the sleeve connected to the hinge pin is less than a sleeve which completely occupies the radius of the outer peripheral surface of the locking segment.
- the outer peripheral surface may have recesses or grooves running parallel to the hinge axis which define preferred detent positions, but may also have substantially unrestricted circumferential profiling to provide stepless locking in a plurality From opening angles of the vehicle door to achieve a lock. Due to the fact that, as a rule, over the entire course of the opening movement of the door, the brake member engages with the outer circumferential surface of the locking segment, it follows that an escape space for the locking segment only has to correspond approximately to the angles of the segment. Preferably, the front in the direction of movement boundary of the locking segment abuts against a stop surface of the opening, so that not only the locking device is integrated into the hinge half, but also the end stop.
- the outer circumferential surface of the locking segment a plurality of holding positions, for example in the form of grooves, and that the holding positions are also provided radially outwardly opposite the periphery of the locking sleeve outside the locking segment. This ensures, inter alia, that the spring acting on the brake member is not completely relieved when it penetrates into a groove of the outer circumference.
- the reinforcement of the abutment surfaces in the region of the opening in which the angular segment is received can be made by folding a sheet metal portion of the legs of the bending part, but suitably a metal clip is used, which connects the two abutment surfaces via a base which covers the segment. This can, if the insert is manufactured as an injection molded part, also already be injected into the insert. The base covers the segment, so that the hinge pin with attached sleeve can be inserted from below into the opening of the hinge half without the parts colliding.
- the locking sleeve on which the locking segment is arranged made of metal such as steel, so that a high wear resistance.
- it can also be a ceramic sintered part whose shape is possible near the final contour.
- the locking segment preferably has a central, continuous bore, which allows a connection to the hinge pin.
- the cylindrical inner circumference of the bore is expediently provided with a knurling which makes it possible to press the sleeve onto a section of the hinge pin so that it is connected to one another in a rotationally fixed manner. Accordingly, upon rotation of the hinge pin, the angle segment is rotated along the brake member, and due to the bias of the brake member generates a corresponding braking force.
- the insert preferably has an appropriately through opening penetrated by the hinge pin, which makes it possible to axially insert the locking sleeve with the projecting locking segment, so that the hinge pin need not be split in the region of the sleeve.
- the opening in a plane normal to the hinge axis has a first portion and a second portion, wherein the periphery of the opening in the first portion is provided closer to the hinge axis than in the second portion.
- the opening has a first portion with a small radius in which the locking sleeve is peripherally bordered, and a second portion with a larger radius than the first portion in which the angle segment is pivotally mounted at an angle.
- the first portion has a smaller diameter than the second portion, wherein the second portion is substantially facing the stop plane of the hinge half on the door frame.
- the second portion of the opening is dimensioned such that the locking segment is always in engagement with the brake member regardless of an opening angle of the two hinge halves, a spin and thus disengage the two parts of the locking device is prevented.
- the step between the first section and the second section of the opening can advantageously limit the locking segment in its pivoting angle.
- a guide channel is expediently provided, in which the brake member is axially displaceable and guided, wherein the guide channel connects the second portion of the opening with a front side facing away from the first portion of the insert.
- the axes of the guide channel and the opening are expediently arranged perpendicular to each other to allow radial delivery of the brake member.
- the guide channel is formed as a blind hole, against the closed end, the spring member which biases the brake member is supported.
- a support for the end remote from the braking member of the spring member in its axial position in the insert is adjustable to adjust the bias of the spring member and thus achieved between the braking member and outer peripheral surface of the locking segment braking torque.
- the support can be adjusted in various ways, for example by the provision of spacers or by a threaded connection, but preferably the support has a projection facing away from the spring member, which is adjustably fixed in an opening of the support structure to adjust the bias of the spring , It is possible to fix the extension in the set position against the support structure, but preferably the extension is at the same time designed as a fastening means for the hinge part on the motor vehicle door or the door frame, so that the fixing of the adjustment of the bias of the spring force with the connection of the hinge part to the corresponding door assembly part, motor vehicle door or door frame, takes place.
- the attachment to the door assembly part can be done for example by riveting one end of the extension, whereby the extension of a further rotation and thus a change in the Pre-tension of the spring member is prevented.
- Another mounting option is to set a threaded end of the extension with a nut or a countered nut assembly.
- a part of the locking device is at the same time a fastening means for the hinge half on the motor vehicle door or door frame.
- an axis of an opening for a fastening means of the one hinge half with an axis of the hinge pin biases a plane in space.
- the region in which the projection or the fastening means is connected to the support structure with a somewhat greater thickness, for example by means of a pull-through, which produces a thickening of the mass of the base of the support structure in the region of its opening, which is designed to be more stable.
- the passage in this case has a diameter which is smaller than the diameter of the guide channel, but is preferably adapted to the diameter of the guide channel, so that when inserting the insert at the same time an additional positive fixation of the insert takes place on the support structure.
- the extension which is also designed as a fastening means and which penetrates the base of the support structure, also fixes the insert on the support structure. It is possible to provide by the adjustability of the support up or reduced braking torques for the hinge in a particularly advantageous position for dip painting. In this case, the hinge can be provisionally fixed to the door frame by means of the fastening means.
- the fastening means passes through an opening of a hinge half, and the opening is aligned with a at least a portion of the locking device receiving guide channel.
- the eye is provided as a bent sheet metal part in the leg of the bent sheet metal part.
- the eye is lined for this purpose with a socket, which ensures the rotational mobility of the hinge pin in the hinge half.
- the hinge pin is expediently mounted in a rotatable manner in each case in one eye of each of the two legs with a corresponding collar bushing.
- the leg (s) advantageously delimits axially the opening which is formed in the insert as a continuous opening, so that the receptacle for the securing device is suitably encapsulated against the ingress of contaminants.
- the hinge pin is riveted on one side of the leg facing away from the other hinge half, wherein this can be done directly on the collar part of the bush designed as a collar bushing.
- the insert and the support structure are advantageously clamped axially, so that the ingress of contaminants on the mutually facing surfaces of the legs and the insert is effectively avoided. If this seal is not sufficient, for example, to prevent the ingress of liquids, a sealing tape can be inserted between said parts, which can alternatively be vulcanized on one of the surfaces of support structure and use.
- the spring may be indirectly or directly supported against insert or support frame.
- the vehicle hinge is expediently designed as Amsterdamlenkscharnier, in which a hinge half can be fixed to a first door assembly part, and the other hinge half can be fixed to the other door assembly part.
- a double-cone-shaped opening may be provided, in which a cone portion of the hinge pin from one side and a conical portion having bolts can be inserted from the other side, so that the hinge is lifted altogether.
- a hexagonal recess is provided in the other hinge half, in which a hexagonal portion of the hinge pin can be inserted with a central threaded bore for receiving a bolt.
- the other hinge provided with the double cone or the hexagonal recess may also have a support structure and an insert, for example in which the support structure provides the two conical surfaces and is otherwise formed as a sheet metal bent part, while the insert fills the support structure and thus prevents this bends under the load.
- the hinge half can be provided with the locking device, but in which no locking device is provided. It is also possible to provide a locking device in both hinge halves, for example, when larger opening angle than the usual about 80 degrees are desired, or to provide with the other locking device a preferred stop position for the dip painting, which is no longer needed in the subsequent driving.
- the motor vehicle hinge as a multi-joint hinge, in particular four-bar hinge, in which the actual hinge halves, which are fixed to the door assembly parts, are connected to each other via two links. Then, the handlebar drives the hinge pin, which is fixed in the one hinge half to the locking device in preferred holding positions.
- four-bar hinges are used for example in hoods and tailgates.
- the motor vehicle hinge further includes a first hinge half attachable to one of the vehicle door and door frame, a second hinge half attachable to the other of the vehicle door and door frame, and a hinge pin hingedly connecting the two hinge halves, at least one the two hinge halves has a support structure and an insert, and that the support structure and the insert are mutually fixed.
- This advantageously two properties of the hinge half namely the possibility to accommodate the locking device and the provision of a load bearing, separated into two different parts that are mutually fixed and thus act as a part.
- the hinge pin is mounted on at least one eye of the support structure.
- the support structure and the insert have a different density, so that overall a part which is lighter in weight relative to a solid part is created.
- the motor vehicle hinge comprises a locking device which acts in the insert, that is at least predominantly accommodated therein.
- the locking device sets the two hinge halves mutually releasably fixed in at least certain pivot angles.
- This may be a latching locking device that provides preferred brackets in which a spring member is relatively relaxed by a brake member engages therein.
- This can also be a stepless locking device, which generates different braking torques depending on the set profiling in the corresponding opening angle.
- the locking device may also be a device that secures the pivotal movement of the door by a uniform braking torque against impact by wind gusts. Combinations of the above versions are possible.
- the volume-consuming housing of the locking device is essentially effected by the use, while the inclusion of the loads, which are essentially introduced by the gravity introduced into the hinge half the door and the introduction of the weight of the hinge in the door frame or the vehicle door is characterized, carried by the support structure.
- the insert which has to absorb only small loads, such as the guiding or storing components of the locking device, can be made of a lightweight, less expensive and especially light or even non-machinable material, while the weight and the volume of the support structure on the male Weight can be designed and thus is not oversized. This results in a significant weight saving, which reduces the weight of the vehicle and its fuel consumption accordingly.
- the support structure is formed as a metal part, while the insert is formed as a plastic part. Both materials have favorable properties in terms of formability, manufacturability and weight for the specific requirements, so that the resulting motor vehicle hinge is sufficiently stable to absorb the loads, and yet not oversized.
- the insert is fixed to the support structure, for example, positive or non-positive, but alternatively also by gluing or by cohesive bonding.
- the hinge half can be produced in that the support structure consists of one or more metal parts, which are encapsulated in an injection mold with plastic, or of a plastic part, in which the support structure is used in corresponding guides in one or more parts.

Description
Die Erfindung betrifft ein Kraftfahrzeugscharnier nach dem Oberbegriff des unabhängigen Anspruchs.The invention relates to a motor vehicle hinge according to the preamble of the independent claim.
Es ist die Aufgabe der Erfindung, ein Kraftfahrzeugscharnier anzugeben, das bezüglich Dimension und Gewicht verbessert ist.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Kraftfahrzeugscharnier mit den Merkmalen des unabhängigen Anspruchs.
It is the object of the invention to provide a motor vehicle hinge which is improved in dimension and weight.
This object is achieved by a motor vehicle hinge with the features of the independent claim.
Gemäß der Erfindung ist ein Kraftfahrzeugscharnier geschaffen, eine erste Scharnierhälfte, die an einem von Kraftfahrzeugtür und Türrahmen befestigbar ist, eine zweite Scharnierhälfte, die an dem anderen von Kraftfahrzeugtür und Türrahmen befestigbar ist, einen Scharnierstift, der die beiden Scharnierhälften gelenkig verbindet, und eine in einer der beiden Scharnierhälften angeordnete Feststelleinrichtung, die die beiden Scharnierhälften in zumindest bestimmten Schwenkwinkeln gegenseitig lösbar festlegt, wobei die Feststelleinrichtung eine dem Scharnierstift zugeordnete Feststellhülse und ein mit der Feststellhülse zusammenwirkendes Bremsglied aufweist, wobei die Feststelleinrichtung eine dem Scharnierstift zugeordnete Feststellhülse mit einem radial vorspringenden Feststellsegment und ein mit einer Umfangsfläche des Feststellsegments zusammenwirkendes Bremsglied aufweist, wobei das Bremsglied vorzugsweise radial gegen die äußere Umfangsfläche des Feststellsegments von einem Federglied vorgespannt ist. Durch das radial vorspringende Feststellsegment wird vorteilhaft ein größerer äußerer Umfang des Feststellsegments bereitgestellt, der eine entsprechend bessere Auflösung für bestimmte Feststellpositionen ermöglicht, ohne hierdurch die Abmessungen der Feststellhülse insgesamt und/oder die Abmessungen der die Feststellhülse aufnehmenden Öffnung insgesamt zu vergrößern. Im Fall einer rastenden Feststellcharakteristik kann diese durch Auswechseln der Feststellhülse bei im Übrigen unveränderten Scharnier geändert werden, z.B. für verschiedene Fahrzeugmodelle.According to the invention, there is provided a motor vehicle hinge, a first hinge half attachable to one of the motor vehicle door and door frame, a second hinge half securable to the other of the motor vehicle door and door frame, a hinge pin hingedly connecting the two hinge halves, and an inboard hinge one of the two hinge halves arranged locking device, which determines the two hinge halves mutually releasably in at least certain pivoting angles, wherein the locking device comprises a hinge pin associated with the locking sleeve and cooperating with the locking brake member, wherein the locking device associated with the hinge pin locking sleeve with a radially projecting locking segment and a cooperating with a peripheral surface of the locking segment brake member, wherein the brake member is preferably radially against the outer peripheral surface of the locking segment v is biased on a spring member. Due to the radially projecting locking segment, a larger outer circumference of the locking segment is advantageously provided which allows a correspondingly better resolution for certain locking positions, without thereby increasing the overall dimensions of the locking sleeve and / or the dimensions of the locking sleeve receiving opening. In the case of a latching locking characteristic this can be changed by replacing the locking sleeve with otherwise unchanged hinge, e.g. for different vehicle models.
Die äußere Umfangsfläche kann sich über einen Winkelbereich erstrecken, der einem Öffnungswinkel der Kraftfahrzeugtür, in der Regel ca. 75 Grad, maximal 90 Grad, entspricht. Die äußere Umfangsfläche springt radial gegenüber dem übrigen Umfang des Feststellsegments nach Art eines Winkelsegments vor, wodurch die Begrenzungsflächen des Winkelsegments, die die äußere Umfangsfläche mit dem Hülsenteil der Feststellhülse verbinden, zugleich den Anschlag für maximale und minimale Öffnungswinkel bilden. Der übrige Umfang des Feststellsegments ist hierbei im Wesentlichen als zylindrischer Mantelabschnitt gebildet, der in einer entsprechend kleindimensionierten Abschnitt der Öffnung der Scharnierhälfte aufgenommen ist. Es ist möglich, dass der übrige Umfang zugleich der Lagerung in dieser Öffnung dient, um die Schwenk- oder Drehbewegung des Winkelsegments zu unterstützen, vorzugsweise ist aber vorgesehen, dass der gesamte Umfang der Feststellhülse von der Öffnung beabstandet angeordnet ist, und damit allenfalls die anschlagenden Begrenzungsflächen des Feststellsegments gegen Teile der Öffnung in Anlage gelangen - hierdurch wird Reibung und Geräuschentwicklung sowie eine unerwünschte Änderung der Bremskraft bei sich ändernden tribologischen Parametern vermieden.The outer circumferential surface may extend over an angular range, the maximum opening angle of the vehicle door, usually about 75 degrees 90 degrees, corresponds. The outer circumferential surface protrudes radially relative to the remaining circumference of the locking segment in the manner of an angular segment, whereby the boundary surfaces of the angle segment, which connect the outer peripheral surface with the sleeve part of the locking sleeve, at the same time form the stop for maximum and minimum opening angle. The rest of the circumference of the locking segment is in this case formed essentially as a cylindrical shell portion, which is received in a correspondingly small-sized portion of the opening of the hinge half. It is possible that the rest of the circumference at the same time the storage in this opening is used to support the pivoting or rotational movement of the angle segment, but it is preferably provided that the entire circumference of the locking sleeve is arranged spaced from the opening, and thus possibly the abutting Limiting surfaces of the locking segment against parts of the opening come into abutment - this friction and noise and an undesirable change in braking force is avoided with changing tribological parameters.
Durch das Vorsehen des Winkelsegments, das einen mindestens um 20 % größeren Radius aufweist als der übrige Umfang des Feststellsegments, wird eine entsprechend große Auflösung im Bereich von dessen äußerer Umfangsfläche erreicht, wobei die Öffnung für die Aufnahme der Hülse mit dem Feststellsegment kleiner bemessen sein kann, da das Feststellsegment nur einen Winkel überfährt, der bei dem doppelten Öffnungswinkel der Fahrzeugtür entspricht, und damit in der Regel kleiner als 180 Grad ist. Damit kann insbesondere das kritische Maß, nämlich der Abstand der Anlageebene der Scharnierhälfte mit dem Türrahmen oder der Kraftfahrzeugtür zu dem abgekehrten Ende, kleiner ausfallen. Weiterhin ist die Masse der an dem Scharnierstift angeschlossenen Hülse geringer als eine Hülse, die vollständig den Radius der äußeren Umfangsfläche des Feststellsegments einnimmt. Die äußere Umfangsfläche kann parallel zur Scharnierachse laufende Ausnehmungen oder Nuten aufweisen, die bevorzugte Raststellungen definieren, sie kann aber auch eine im Wesentlichen ungestufte Umfangsprofilierung aufweisen, um ein stufenloses Feststellen in einer Vielzahl von Öffnungswinkeln der Fahrzeugtür einer Arretierung zu erreichen. Dadurch, dass in der Regel über den gesamten Verlauf der Öffnungsbewegung der Tür das Bremsglied mit der äußeren Umfangsfläche des Feststellsegments in Eingriff steht, ergibt sich, dass ein Ausweichraum für das Feststellsegment lediglich annähernd den Winkeln des Segments entsprechen muss. Vorzugsweise schlägt die in Bewegungsrichtung vorne liegende Begrenzung des Feststellsegments gegen eine Anschlagfläche der Öffnung an, so dass nicht nur die Feststelleinrichtung in die Scharnierhälfte integriert ist, sondern auch der Endanschlag.By providing the angle segment, which has at least a 20% larger radius than the rest of the circumference of the locking segment, a correspondingly large resolution is achieved in the region of the outer peripheral surface, wherein the opening for receiving the sleeve with the locking segment can be made smaller because the locking segment only passes over an angle that corresponds to twice the opening angle of the vehicle door, and thus is usually less than 180 degrees. Thus, in particular the critical dimension, namely the distance of the contact plane of the hinge half with the door frame or the motor vehicle door to the remote end, turn out smaller. Furthermore, the mass of the sleeve connected to the hinge pin is less than a sleeve which completely occupies the radius of the outer peripheral surface of the locking segment. The outer peripheral surface may have recesses or grooves running parallel to the hinge axis which define preferred detent positions, but may also have substantially unrestricted circumferential profiling to provide stepless locking in a plurality From opening angles of the vehicle door to achieve a lock. Due to the fact that, as a rule, over the entire course of the opening movement of the door, the brake member engages with the outer circumferential surface of the locking segment, it follows that an escape space for the locking segment only has to correspond approximately to the angles of the segment. Preferably, the front in the direction of movement boundary of the locking segment abuts against a stop surface of the opening, so that not only the locking device is integrated into the hinge half, but also the end stop.
Vorteilhaft ist vorgesehen, dass die äußere Umfangsfläche des Feststellsegments mehrere Haltepositionen, beispielsweise in Form von Nuten, aufweist, und dass die Haltepositionen ebenfalls gegenüber dem Umfang der Feststellhülse außerhalb des Feststellsegments radial weiter außenliegend vorgesehen sind. Hierdurch wird unter anderem sichergestellt, dass die das Bremsglied beaufschlagende Feder nicht vollständig entlastet wird, wenn sie in eine Nut des äußeren Umfangs eindringt.Advantageously, it is provided that the outer circumferential surface of the locking segment a plurality of holding positions, for example in the form of grooves, and that the holding positions are also provided radially outwardly opposite the periphery of the locking sleeve outside the locking segment. This ensures, inter alia, that the spring acting on the brake member is not completely relieved when it penetrates into a groove of the outer circumference.
Es ist möglich, die Anschlagfläche mit Metall auszukleiden, um einen Verschleiß zu verhindern. Die Verstärkung der Anschlagflächen im Bereich der Öffnung, in dem das Winkelsegment aufgenommen ist, kann durch Abfalten eines Blechabschnitts der Schenkel des Biegeteils erfolgen, zweckmäßigerweise wird aber eine Metallklammer eingesetzt, die die beiden Anschlagflächen über eine Basis, die das Segment bedeckt, verbindet. Diese kann, wenn der Einsatz als Spritzgussteil hergestellt wird, auch bereits mit in den Einsatz eingespritzt sein. Die Basis überdeckt hierbei das Segment, so dass der Scharnierstift mit angeschlossener Hülse von unten in die Öffnung der Scharnierhälfte eingeschoben werden kann, ohne dass die Teile kollidieren.It is possible to line the stop face with metal to prevent wear. The reinforcement of the abutment surfaces in the region of the opening in which the angular segment is received, can be made by folding a sheet metal portion of the legs of the bending part, but suitably a metal clip is used, which connects the two abutment surfaces via a base which covers the segment. This can, if the insert is manufactured as an injection molded part, also already be injected into the insert. The base covers the segment, so that the hinge pin with attached sleeve can be inserted from below into the opening of the hinge half without the parts colliding.
Zweckmäßigerweise ist die Feststellhülse, an der das Feststellsegment angeordnet ist, aus Metall wie Stahl hergestellt, so dass eine hohe Verschleißfestigkeit besteht. Alternativ kann es sich aber auch um ein Sinterteil aus Keramik handeln, dessen Formgebung nahe der Endkontur möglich ist. Das Feststellsegment weist vorzugsweise eine zentrale, durchgehende Bohrung auf, die einen Anschluss an den Scharnierstift ermöglicht. Hierzu ist zweckmäßigerweise der zylindrische Innenumfang der Bohrung mit einer Rändelung ausgestattet, die ein Aufpressen der Hülse auf einen Abschnitt des Scharnierstifts ermöglicht, so dass diese drehfest miteinander verbunden sind. Entsprechend wird bei Drehung des Scharnierstifts das Winkelsegment entlang des Bremsglieds verdreht, und aufgrund der Vorspannung des Bremsglieds eine entsprechende Bremskraft erzeugt.Conveniently, the locking sleeve on which the locking segment is arranged, made of metal such as steel, so that a high wear resistance. Alternatively, it can also be a ceramic sintered part whose shape is possible near the final contour. The locking segment preferably has a central, continuous bore, which allows a connection to the hinge pin. For this purpose, the cylindrical inner circumference of the bore is expediently provided with a knurling which makes it possible to press the sleeve onto a section of the hinge pin so that it is connected to one another in a rotationally fixed manner. Accordingly, upon rotation of the hinge pin, the angle segment is rotated along the brake member, and due to the bias of the brake member generates a corresponding braking force.
Der Einsatz weist vorzugsweise eine von dem Scharnierstift durchsetzte, zweckmäßigerweise durchgehende Öffnung auf, die es ermöglicht, die Feststellhülse mit dem vorspringenden Feststellsegment axial einzuführen, so dass der Scharnierstift im Bereich der Hülse nicht geteilt ausgebildet sein muss.The insert preferably has an appropriately through opening penetrated by the hinge pin, which makes it possible to axially insert the locking sleeve with the projecting locking segment, so that the hinge pin need not be split in the region of the sleeve.
Vorzugsweise weist die Öffnung in einer Ebene normal zu der Scharnierachse einen ersten Abschnitt und einen zweiten Abschnitt aufweist, wobei der Umfang der Öffnung im ersten Abschnitt näher an der Scharnierachse vorgesehen ist als im zweiten Abschnitt. Die Öffnung weist einen ersten Abschnitt mit einem kleinen Radius auf, in dem die Feststellhülse umfangsmäßig eingefasst ist, und einen zweiten Abschnitt mit größerem Radius als dem ersten Abschnitt, in dem das Winkelsegment über einen Winkel verschwenkbar angeordnet ist. Der erste Abschnitt weist einen kleineren Durchmesser auf als der zweite Abschnitt, wobei der zweite Abschnitt im Wesentlichen der Anschlagebene der Scharnierhälfte an dem Türrahmen zugekehrt ist. Hierdurch wird der Abstand zwischen Anschlagebene der Scharnierhälfte an ein Türanordnungsteil und dem distalen Ende der Scharnierhälfte, in dem der Scharnierstift verläuft und das auch als Kopfrolle bezeichnet wird, verringert und entsprechen ein geringerer Einbauraum benötigt.Preferably, the opening in a plane normal to the hinge axis has a first portion and a second portion, wherein the periphery of the opening in the first portion is provided closer to the hinge axis than in the second portion. The opening has a first portion with a small radius in which the locking sleeve is peripherally bordered, and a second portion with a larger radius than the first portion in which the angle segment is pivotally mounted at an angle. The first portion has a smaller diameter than the second portion, wherein the second portion is substantially facing the stop plane of the hinge half on the door frame. As a result, the distance between the stop plane of the hinge half to a door assembly part and the distal end of the hinge half, in which the hinge pin extends and which is also referred to as a head roller, reduced and correspond to a smaller installation space required.
Vorzugsweise ist der zweite Abschnitt der Öffnung so bemessen, dass das Feststellsegment unabhängig von einem Öffnungswinkel der beiden Scharnierhälften stets mit dem Bremsglied in Eingriff steht, ein Durchdrehen und damit ein außer Eingriff gelangen der beiden Teile der Feststelleinrichtung damit verhindert ist. Die Stufe zwischen erstem Abschnitt und zweitem Abschnitt der Öffnung kann vorteilhaft das Feststellsegment in seinem Schwenkwinkel begrenzen.Preferably, the second portion of the opening is dimensioned such that the locking segment is always in engagement with the brake member regardless of an opening angle of the two hinge halves, a spin and thus disengage the two parts of the locking device is prevented. The step between the first section and the second section of the opening can advantageously limit the locking segment in its pivoting angle.
In dem Einsatz ist zweckmäßigerweise ein Führungskanal vorgesehen, in dem das Bremsglied axial verlagerbar und geführt ist, wobei der Führungskanal den zweiten Abschnitt der Öffnung mit einer dem ersten Abschnitt abgekehrten Stirnseite des Einsatzes verbindet. Die Achsen des Führungskanals und der Öffnung sind hierbei zweckmäßig senkrecht zueinander angeordnet, um eine radiale Zustellung des Bremsgliedes zu ermöglichen. Es ist aber alternativ auch möglich, dass der Führungskanal als Sackloch ausgebildet ist, gegen dessen geschlossenes Ende sich das Federglied, das das Bremsglied vorspannt, abstützt.In the insert a guide channel is expediently provided, in which the brake member is axially displaceable and guided, wherein the guide channel connects the second portion of the opening with a front side facing away from the first portion of the insert. The axes of the guide channel and the opening are expediently arranged perpendicular to each other to allow radial delivery of the brake member. But it is alternatively also possible that the guide channel is formed as a blind hole, against the closed end, the spring member which biases the brake member is supported.
Gemäß einer bevorzugten Weiterbildung ist vorgesehen, dass eine Abstützung für das dem Bremsglied abgekehrte Ende des Federglieds in seiner axialen Lage in dem Einsatz verstellbar ist, um die Vorspannung des Federglieds und damit das zwischen Bremsglied und äußerer Umfangsfläche des Feststellsegments erreichte Bremsmoment einzustellen. Die Abstützung kann auf verschiedene Art und Weise verstellt werden, beispielsweise durch das Vorsehen von Zwischenstücken oder durch eine Gewindeverbindung, vorzugsweise weist die Abstützung jedoch einen dem Federglied abgekehrten Fortsatz auf, der in einer Durchbrechung der Tragstruktur verstellbar festlegbar ist, um die Vorspannung der Feder einzustellen. Es ist möglich, den Fortsatz in der eingestellten Position gegen die Tragstruktur zu fixieren, vorzugsweise ist der Fortsatz aber zugleich als Befestigungsmittel für das Scharnierteil an der Kraftfahrzeugtür oder dem Türrahmen ausgebildet, so dass die Fixierung der Einstellung der Vorspannung der Federkraft mit dem Anschluss des Scharnierteils an das entsprechende Türanordnungsteil, Kraftfahrzeugtür oder Türrahmen, erfolgt. Die Befestigung an dem Türanordnungsteil kann beispielsweise durch Vernieten eines Endes des Fortsatzes erfolgen, wodurch der Fortsatz an einer weiteren Verdrehung und damit einer Veränderung der Vorspannung des Federglieds gehindert ist. Eine andere Befestigungsmöglichkeit besteht darin, ein Gewindeende des Fortsatzes mit einer Mutter oder einer gekonterten Mutternanordnung festzulegen.According to a preferred embodiment it is provided that a support for the end remote from the braking member of the spring member in its axial position in the insert is adjustable to adjust the bias of the spring member and thus achieved between the braking member and outer peripheral surface of the locking segment braking torque. The support can be adjusted in various ways, for example by the provision of spacers or by a threaded connection, but preferably the support has a projection facing away from the spring member, which is adjustably fixed in an opening of the support structure to adjust the bias of the spring , It is possible to fix the extension in the set position against the support structure, but preferably the extension is at the same time designed as a fastening means for the hinge part on the motor vehicle door or the door frame, so that the fixing of the adjustment of the bias of the spring force with the connection of the hinge part to the corresponding door assembly part, motor vehicle door or door frame, takes place. The attachment to the door assembly part can be done for example by riveting one end of the extension, whereby the extension of a further rotation and thus a change in the Pre-tension of the spring member is prevented. Another mounting option is to set a threaded end of the extension with a nut or a countered nut assembly.
Gemäß einem bevorzugten Aspekt ist ein Teil der Feststelleinrichtung zugleich ein Befestigungsmittel für die Scharnierhälfte an Kraftfahrzeugtür oder Türrahmen. Gemäß einem anderen bevorzugten Aspekt spannt eine Achse einer Durchbrechung für ein Befestigungsmittel der einen Scharnierhälfte mit einer Achse des Scharnierstiftes eine Ebene im Raum auf.According to a preferred aspect, a part of the locking device is at the same time a fastening means for the hinge half on the motor vehicle door or door frame. According to another preferred aspect, an axis of an opening for a fastening means of the one hinge half with an axis of the hinge pin biases a plane in space.
Das Vorsehen eines Befestigungsmittels, das in der Verlängerung des Führungskanals bzw. des Bremsgliedes verläuft und damit keinen seitlichen Versatz und damit keinen Moment gegenüber der angreifenden Last bzw. der kürzesten Verbindungslinie Scharnierachse-Befestigungsebene aufweist, ermöglicht es, die Tragstruktur etwas weniger massiv und damit mit geringerem Gewicht auszubilden.The provision of a fastener that extends in the extension of the guide channel and the brake member and thus has no lateral offset and thus no moment against the load or the shortest connecting line hinge axis mounting plane allows the support structure slightly less massive and thus with to train less weight.
Es ist weiter möglich, den Bereich, in dem der Fortsatz bzw. das Befestigungsmittel an der Tragstruktur angeschlossen ist, mit einer etwas größeren Stärke auszubilden, beispielsweise mittels eines Durchzugs, der eine Verdickung der Masse der Basis der Tragstruktur im Bereich von deren Durchbrechung erzeugt, die entsprechend stabiler ausgeführt ist. Der Durchzug hat hierbei einen Durchmesser, der geringer ist als der Durchmesser des Führungskanals, vorzugsweise aber an dem Durchmesser des Führungskanals angepasst ist, so dass bei Einschieben des Einsatzes zugleich eine zusätzliche formschlüssige Fixierung des Einsatzes an der Tragstruktur erfolgt. Der Fortsatz, der zugleich als Befestigungsmittel ausgebildet ist und der die Basis der Tragstruktur durchsetzt, fixiert überdies den Einsatz an der Tragstruktur. Es ist möglich, durch die Verstellbarkeit der Abstützung herauf- oder herabgesetzte Bremsmomente für das Scharnier in einer für die Tauchlackierung besonders vorteilhaften Position vorzusehen. Hierbei kann das Scharnier mit Hilfe der Befestigungsmittel vorläufig an dem Türrahmen festgelegt sein.It is further possible to form the region in which the projection or the fastening means is connected to the support structure with a somewhat greater thickness, for example by means of a pull-through, which produces a thickening of the mass of the base of the support structure in the region of its opening, which is designed to be more stable. The passage in this case has a diameter which is smaller than the diameter of the guide channel, but is preferably adapted to the diameter of the guide channel, so that when inserting the insert at the same time an additional positive fixation of the insert takes place on the support structure. The extension, which is also designed as a fastening means and which penetrates the base of the support structure, also fixes the insert on the support structure. It is possible to provide by the adjustability of the support up or reduced braking torques for the hinge in a particularly advantageous position for dip painting. In this case, the hinge can be provisionally fixed to the door frame by means of the fastening means.
Vorzugsweise durchsetzt das Befestigungsmittel eine Durchbrechung der einen Scharnierhälfte, und die Durchbrechung fluchtet mit einem zumindest ein Teil der Feststelleinrichtung aufnehmenden Führungskanal.Preferably, the fastening means passes through an opening of a hinge half, and the opening is aligned with a at least a portion of the locking device receiving guide channel.
Vorzugsweise ist das Auge bei Ausgestaltung der Tragstruktur als Blechbiegeteil in dem Schenkel des Blechbiegeteils vorgesehen ist. Das Auge wird hierzu mit einer Buchse ausgekleidet, die die Drehbeweglichkeit des Scharnierstifts in der Scharnierhälfte sicherstellt. Weist das Blechbiegeteil zwei Schenkel auf, wird zweckmäßigerweise der Scharnierstift in jeweils einem Auge jedes der beiden Schenkel mit einer entsprechenden Kragenbuchse drehbeweglich gelagert. Der oder die Schenkel begrenzen zugleich vorteilhaft die Öffnung, die in dem Einsatz als durchgehende Öffnung ausgebildet ist, axial, so dass die Aufnahme für die Feststelleinrichtung gegen Eindringen von Verunreinigungen günstigerweise gekapselt ist. Zweckmäßigerweise wird der Scharnierstift auf einer der anderen Scharnierhälfte abgekehrten Seite des Schenkels vernietet, wobei dies unmittelbar auf dem Kragenteil der als Kragenbuchse ausgebildeten Buchse erfolgen kann. Hierdurch werden der Einsatz und die Tragstruktur vorteilhaft axial verklammert, so dass das Eindringen von Verunreinigungen an den einander zugekehrten Flächen der Schenkel und des Einsatzes wirksam vermieden wird. Sollte diese Abdichtung nicht ausreichen, beispielswiese um das Eindringen von Flüssigkeiten zu vermeiden, kann zwischen den genannten Teilen ein Dichtband eingelegt werden, das alternativ auch auf einer der Flächen von Tragstruktur und Einsatz aufvulkanisiert sein kann.Preferably, in the embodiment of the support structure, the eye is provided as a bent sheet metal part in the leg of the bent sheet metal part. The eye is lined for this purpose with a socket, which ensures the rotational mobility of the hinge pin in the hinge half. If the bent sheet metal part has two legs, the hinge pin is expediently mounted in a rotatable manner in each case in one eye of each of the two legs with a corresponding collar bushing. At the same time, the leg (s) advantageously delimits axially the opening which is formed in the insert as a continuous opening, so that the receptacle for the securing device is suitably encapsulated against the ingress of contaminants. Conveniently, the hinge pin is riveted on one side of the leg facing away from the other hinge half, wherein this can be done directly on the collar part of the bush designed as a collar bushing. As a result, the insert and the support structure are advantageously clamped axially, so that the ingress of contaminants on the mutually facing surfaces of the legs and the insert is effectively avoided. If this seal is not sufficient, for example, to prevent the ingress of liquids, a sealing tape can be inserted between said parts, which can alternatively be vulcanized on one of the surfaces of support structure and use.
Eine alternative Feststelleinrichtung, die keinen Teil der Erfindung formt, umfasst einen Rastring, der undrehbar an den Scharnierstift angeschlossen ist und sich mit diesem dreht, und einen konzentrischen Nockenring, der von einer Feder gegen den Rastring vorgespannt ist, die einander zugekehrte axiale Flächen aufweisen und die bei gegenseitiger Drehung eine Bremskraft erzeugen. Die Feder kann mittelbar oder unmittelbar gegen Einsatz oder Tragrahmen abgestützt sein.An alternative locking device which does not form part of the invention comprises a locking ring which is non-rotatably connected to the hinge pin and rotates therewith, and a concentric cam ring which is biased by a spring against the locking ring having facing axial surfaces and which generate a braking force with mutual rotation. The spring may be indirectly or directly supported against insert or support frame.
Das Fahrzeugscharnier ist zweckmäßigerweise als Eingelenkscharnier ausgebildet, bei dem eine Scharnierhälfte an einem ersten Türanordnungsteil festgelegt werden kann, und die andere Scharnierhälfte an dem anderen Türanordnungsteil festgelegt werden kann. Hierzu kann in der anderen, nicht mit der Feststelleinrichtung ausgestatteten Scharnierhälfte eine doppelkonusförmige Öffnung vorgesehen sein, in die ein Konusabschnitt des Scharnierstifts von der einen Seite und ein einen Konusbereich aufweisender Schraubenbolzen von der anderen Seite eingesetzt werden kann, so dass das Scharnier insgesamt aushebbar ist. Alternativ ist eine Sechskantausnehmung in der anderen Scharnierhälfte vorgesehen, in die ein Sechskantabschnitt des Scharnierstifts mit einer zentralen Gewindebohrung zur Aufnahme eines Schraubenbolzens eingeführt werden kann. Auch das andere, mit dem Doppelkonus oder der Sechskantausnehmung versehene Scharnier kann hierbei eine Tragstruktur und einen Einsatz aufweisen, beispielsweise in dem die Tragstruktur die beiden Konusförmigen Flächen vorsieht und im Übrigen als Blechbiegeteil gebildet ist, während der Einsatz die Tragstruktur ausfüllt und damit verhindert, dass sich diese unter der Last aufbiegt. Unter Umständen kann sogar derselbe oder ein vergleichbarer Einsatz wie für die Scharnierhälfte mit der Feststelleinrichtung vorgesehen sein, in der aber keine Feststelleinrichtung vorgesehen ist. Es ist auch möglich, eine Feststelleinrichtung in beiden Scharnierhälften vorzusehen, beispielsweise wenn größere Öffnungswinkel als die üblichen ca. 80 Grad erwünscht sind, oder aber um mit der weiteren Feststelleinrichtung eine bevorzugte Halteposition für die Tauchlackierung vorzusehen, die im späteren Fahrbetrieb nicht mehr benötigt wird.The vehicle hinge is expediently designed as Einelenkscharnier, in which a hinge half can be fixed to a first door assembly part, and the other hinge half can be fixed to the other door assembly part. For this purpose, in the other, not provided with the locking device hinge half a double-cone-shaped opening may be provided, in which a cone portion of the hinge pin from one side and a conical portion having bolts can be inserted from the other side, so that the hinge is lifted altogether. Alternatively, a hexagonal recess is provided in the other hinge half, in which a hexagonal portion of the hinge pin can be inserted with a central threaded bore for receiving a bolt. The other hinge provided with the double cone or the hexagonal recess may also have a support structure and an insert, for example in which the support structure provides the two conical surfaces and is otherwise formed as a sheet metal bent part, while the insert fills the support structure and thus prevents this bends under the load. Under certain circumstances, even the same or a similar use as for the hinge half can be provided with the locking device, but in which no locking device is provided. It is also possible to provide a locking device in both hinge halves, for example, when larger opening angle than the usual about 80 degrees are desired, or to provide with the other locking device a preferred stop position for the dip painting, which is no longer needed in the subsequent driving.
Alternativ ist es auch möglich, das Kraftfahrzeugscharnier als Mehrgelenkscharnier, insbesondere Viergelenkscharnier auszubilden, bei dem die eigentlichen Scharnierhälften, die an die Türanordnungsteile festgelegt werden, über zwei Lenker miteinander verbunden sind. Dann treibt der Lenker den Scharnierstift an, der in der einen Scharnierhälfte an die Feststelleinrichtung in bevorzugten Haltestellungen festlegbar ist. Solche Viergelenkscharniere werden beispielsweise bei Motorhauben und Heckklappen eingesetzt.Alternatively, it is also possible to form the motor vehicle hinge as a multi-joint hinge, in particular four-bar hinge, in which the actual hinge halves, which are fixed to the door assembly parts, are connected to each other via two links. Then, the handlebar drives the hinge pin, which is fixed in the one hinge half to the locking device in preferred holding positions. Such four-bar hinges are used for example in hoods and tailgates.
Gemäß einem Aspekt umfasst das Kraftfahrzeugscharnier zusätzlich eine erste Scharnierhälfte, die an einem von Kraftfahrzeugtür und Türrahmen befestigbar ist, eine zweite Scharnierhälfte, die an dem anderen von Kraftfahrzeugtür und Türrahmen befestigbar ist, und einen Scharnierstift, der die beiden Scharnierhälften gelenkig verbindet, wobei zumindest eine der beiden Scharnierhälften eine Tragstruktur und einen Einsatz aufweist, und dass die Tragstruktur und der Einsatz gegenseitig fixiert sind. Damit werden vorteilhaft zwei Eigenschaften der Scharnierhälfte, nämlich die Möglichkeit zur Unterbringung der Feststelleinrichtung und das Vorsehen einer Lastaufnahme, in zwei verschiedene Teile separiert, die gegenseitig fixiert sind und damit wie ein Teil wirken. Hierbei ist der Scharnierstift an zumindest einem Auge der Tragstruktur gelagert. Zweckmäßigerweise, aber nicht notwendigerweise haben die Tragstruktur und der Einsatz eine unterschiedliche Dichte, so dass insgesamt ein gegenüber einem massiven Teil leichtgewichtigeres Teil geschaffen ist.In one aspect, the motor vehicle hinge further includes a first hinge half attachable to one of the vehicle door and door frame, a second hinge half attachable to the other of the vehicle door and door frame, and a hinge pin hingedly connecting the two hinge halves, at least one the two hinge halves has a support structure and an insert, and that the support structure and the insert are mutually fixed. This advantageously two properties of the hinge half, namely the possibility to accommodate the locking device and the provision of a load bearing, separated into two different parts that are mutually fixed and thus act as a part. Here, the hinge pin is mounted on at least one eye of the support structure. Expediently, but not necessarily, the support structure and the insert have a different density, so that overall a part which is lighter in weight relative to a solid part is created.
Vorzugsweise umfasst das Kraftfahrzeugscharnier eine Feststelleinrichtung, die in dem Einsatz wirkt, also zumindest überwiegend darin untergebracht ist. Die Feststelleinrichtung legt die die beiden Scharnierhälften in zumindest bestimmten Schwenkwinkeln gegenseitig lösbar fest. Dies kann eine rastende Feststelleinrichtung sein, die bevorzugte Haltewinkel vorsieht, in denen ein Federglied relativ entspannt ist, indem ein Bremsglied darin einrastet. Dies kann auch eine stufenlose Feststelleinrichtung sein, die je nach eingestellter Profilierung in dem entsprechenden Öffnungswinkel unterschiedliche Bremsmomente erzeugt. Weiterhin kann die Feststelleinrichtung auch eine Einrichtung sein, die die Schwenkbewegung der Tür durch ein gleichmäßiges Bremsmoment gegen Aufschlagen durch Windböen sichert. Auch Kombinationen der genannten Ausführungen sind möglich.Preferably, the motor vehicle hinge comprises a locking device which acts in the insert, that is at least predominantly accommodated therein. The locking device sets the two hinge halves mutually releasably fixed in at least certain pivot angles. This may be a latching locking device that provides preferred brackets in which a spring member is relatively relaxed by a brake member engages therein. This can also be a stepless locking device, which generates different braking torques depending on the set profiling in the corresponding opening angle. Furthermore, the locking device may also be a device that secures the pivotal movement of the door by a uniform braking torque against impact by wind gusts. Combinations of the above versions are possible.
Die volumenmäßig aufwändige Unterbringung der Feststelleinrichtung wird im Wesentlichen durch den Einsatz bewirkt, während die Aufnahme der Lasten, die im Wesentlichen durch die in die Scharnierhälfte eingeleitete Gewichtskraft der Tür und das Einleiten der Gewichtskraft des Scharniers in den Türrahmen oder die Kraftfahrzeugtür gekennzeichnet ist, durch die Tragstruktur erfolgt. Der Einsatz, der nur geringen Lasten aufzunehmen hat, wie beispielsweise das Führen oder Lagern von Bestandteilen der Feststelleinrichtung, kann aus einem leichtgewichtigen, weniger teuren und insbesondere leichter oder gar nicht zu bearbeitenden Werkstoff erfolgen, während das Gewicht und das Volumen der Tragstruktur auf die aufzunehmende Gewichtskraft ausgelegt werden kann und damit nicht überdimensioniert ist. Hieraus resultiert eine erhebliche Gewichtseinsparung, die das Gewicht des Fahrzeugs und dessen Kraftstoffverbrauch entsprechend reduziert.The volume-consuming housing of the locking device is essentially effected by the use, while the inclusion of the loads, which are essentially introduced by the gravity introduced into the hinge half the door and the introduction of the weight of the hinge in the door frame or the vehicle door is characterized, carried by the support structure. The insert, which has to absorb only small loads, such as the guiding or storing components of the locking device, can be made of a lightweight, less expensive and especially light or even non-machinable material, while the weight and the volume of the support structure on the male Weight can be designed and thus is not oversized. This results in a significant weight saving, which reduces the weight of the vehicle and its fuel consumption accordingly.
Vorzugsweise ist die Tragstruktur als Metallteil ausgebildet, während der Einsatz als Kunststoffteil geformt ist. Beide Werkstoffe haben für die spezifischen Anforderungen günstige Eigenschaften hinsichtlich Formbarkeit, Herstellbarkeit und Gewicht, so dass das resultierende Kraftfahrzeugscharnier ausreichend stabil ist, um die Lasten aufzunehmen, und trotzdem nicht überdimensioniert ist. Zweckmäßigerweise ist der Einsatz an der Tragstruktur festgelegt, beispielsweise formschlüssig oder kraftschlüssig, alternativ aber auch durch Kleben oder durch stoffschlüssiges Verbinden. Insbesondere kann die Scharnierhälfte dadurch hergestellt werden, dass die Tragstruktur aus einem oder mehreren Metallteilen besteht, die in einer Spritzgussform mit Kunststoff umspritzt werden, oder aus einem Kunststoffteil, in dem in entsprechenden Führungen die Tragstruktur in einem oder mehreren Teilen eingesetzt wird.Preferably, the support structure is formed as a metal part, while the insert is formed as a plastic part. Both materials have favorable properties in terms of formability, manufacturability and weight for the specific requirements, so that the resulting motor vehicle hinge is sufficiently stable to absorb the loads, and yet not oversized. Conveniently, the insert is fixed to the support structure, for example, positive or non-positive, but alternatively also by gluing or by cohesive bonding. In particular, the hinge half can be produced in that the support structure consists of one or more metal parts, which are encapsulated in an injection mold with plastic, or of a plastic part, in which the support structure is used in corresponding guides in one or more parts.
Vorzugsweise ist die Tragstruktur als L- oder U-förmiges Biegeteil aus Metallblech geformt und weist eine Basis und zumindest einen, vorzugsweise zwei zu der Basis senkrechte Schenkel auf. Das Biegeteil bildet so einen Rahmen, der den Einsatz umfasst und in den der Einsatz eingeschoben werden kann. Hierbei ist der zumindest eine Schenkel vorzugsweise von dem Scharnierstift durchsetzt, so dass die Lagerung des Scharnierstifts an der Tragstruktur erfolgt und so auch Kräfte und Lasten zumindest überwiegend in die Tragstruktur eingeleitet werden. Hierbei ist zweckmäßigerweise vorgesehen, dass die Basis des Biegeteils dem Türrahmen, oder alternativ auch der Tür, zugeordnet ist, und entsprechend wenigstens eine Durchbrechung zur Befestigung an dem entsprechenden Türanordnungsteil, Kraftfahrzeugtür oder Kraftfahrzeugtürrahmen, aufweist. Als Befestigungsmittel kommen Gewindestangen, Nieten, Bolzen, Schrauben oder dergleichen in Betracht. Bei der späteren Entsorgung lassen sich Einsatz und Biegeteil leichter trennen als mit Kunststoff umspritzte Bauteile, so dass ein einfaches Recycling nach Trennung möglich ist.Preferably, the support structure is formed as an L-shaped or U-shaped bent part of sheet metal and has a base and at least one, preferably two legs perpendicular to the base. The bent part thus forms a frame which comprises the insert and into which the insert can be inserted. Here, the at least one leg is preferably penetrated by the hinge pin, so that the storage of the hinge pin takes place on the support structure and so forces and loads are at least predominantly introduced into the support structure. This is expediently provided that the base of the bending part of the door frame, or alternatively the door, is assigned, and correspondingly at least one opening for attachment to the corresponding door assembly part, motor vehicle door or motor vehicle door frame having. As fasteners threaded rods, rivets, bolts, screws or the like come into consideration. In the event of subsequent disposal, the insert and the bent part are easier to separate than components coated with plastic, so that simple recycling after separation is possible.
Es ist möglich, den Einsatz mehrteilig herzustellen, vorzugsweise ist dieser aber einstückig ausgebildet, was im Spritzgussverfahren oder durch Gießen leicht möglich ist. Sind in dem Einsatz Sacklöcher, Hinterschnitte oder dergleichen vorzusehen, kann dieser aus zwei Hälften, beispielsweise geteilt entlang einer Längsachse, zusammengefügt sein, die zusammengesteckt werden. Es ist auch möglich, die Hohlräume, aber auch die Konturen, in der die Feststelleinrichtung bzw. deren Teile angeordnet werden, aus dem Vollmaterial durch spanende Bearbeitung wie beispielsweise Fräsen zu schaffen, einfacher ist es jedoch, entsprechende Kerne beim Spritzgießen vorzusehen; hierbei ist zu beachten, dass die Kerne zur leichteren Entfernung oft einen sehr leichten Konus aufweisen, und die entsprechenden Hohlräume, beispielsweise Kanäle oder Öffnungen, dann ebenfalls einen leichten Konus aufweisen. Werden die Kerne von zwei Seiten eingeführt, kann es sich auch um einen Doppelkonus handeln, dessen Durchmesser nach innen hin abnimmt.It is possible to produce the insert in several parts, but this is preferably formed in one piece, which is easily possible by injection molding or by casting. If blind holes, undercuts or the like are to be provided in the insert, this can be composed of two halves, for example divided along a longitudinal axis, which are put together. It is also possible, the cavities, but also the contours in which the locking device or its parts are arranged to create from the solid material by machining such as milling, but it is easier to provide appropriate cores during injection molding; It should be noted that the cores often have a very slight cone for easy removal, and the corresponding cavities, such as channels or openings, then also have a slight cone. If the cores are introduced from two sides, it can also be a double cone whose diameter decreases inwards.
Vorzugsweise ist der Einsatz in Richtung auf die Basis der Tragstruktur in die Tragstruktur einschiebbar, wodurch eine einfache Montage gewährleistet ist. Hierbei weist die Tragstruktur vorzugsweise ein Rastmittel auf, das in eine Ausnehmung des Einsatzes eindringt und den Einsatz an der Tragstruktur verklipst. Hierdurch ist eine formschlüssige Fixierung gegeben, die für den weiteren Zusammenbau des Scharniers den Einsatz und die Tragstruktur gegenseitig fixiert. Es ist möglich, von den Schenkeln des Biegeteils abgefaltete Blechstreifen nach Art von Anschlägen vorzusehen, die den Einsatz in einer weiteren Ebene, wenn dieser in die Tragstruktur eingeschoben wird, begrenzen und damit die beiden Teile in einer weiteren Richtung gegenseitig fixieren. Alternativ können die Schenkel Verprägungen aufweisen, die rastend oder clipsend in entsprechende Begrenzungsflächen des Einsatzes bzw. Ausnehmungen daraus einrasten. Der Einsatz weist zweckmäßigerweise an dem der Basis abgekehrten Ende eine Verbreiterung auf, die verhindert, dass bei automatischem Einsetzen in die Tragstruktur, beispielsweise durch Roboter oder dergleichen, der Einsatz in der falschen Richtung eingesetzt wird.Preferably, the insert in the direction of the base of the support structure in the support structure can be inserted, whereby a simple assembly is ensured. In this case, the support structure preferably has a latching means which penetrates into a recess of the insert and cleats the insert on the support structure. As a result, a positive fixation is given, which fixes the insert and the supporting structure for the further assembly of the hinge. It is possible, provided by the legs of the bent part folded metal strips on the type of attacks, which limit the use in a further plane when it is inserted into the support structure and thus fix the two parts in another direction each other. Alternatively, the legs may have embossments which engage in detenting or clip-like manner into corresponding boundary surfaces of the insert or recesses therefrom. The insert expediently has a broadening on the end facing away from the base, which prevents the insertion being used in the wrong direction during automatic insertion into the supporting structure, for example by robots or the like.
Gemäß einem Aspekt wird ein Verfahren zur Herstellung einer Scharnierhälfte und vorzugsweise zur anschließenden Verbindung mit einer weiteren Scharnierhälfte zur Herstellung eines Kraftfahrzeugscharniers angegeben, mit den Schritten (S1) Anordnen einer Feststellhülse einer Feststelleinrichtung in einer Öffnung eines Einsatzes; (S2) Einschieben des Einsatzes zusammen mit der Feststellhülse in eine Tragstruktur, wodurch die Feststellhülse nicht mehr aus der Öffnung austreten kann; und (S3) Durchsetzen der Feststellhülse und der Tragstruktur mit einem Scharnierstift.According to one aspect, there is provided a method for making a hinge half, and preferably for subsequent connection to another hinge half for making a motor vehicle hinge, comprising the steps of: (S1) placing a locking sleeve of a locking device in an opening of an insert; (S2) inserting the insert together with the locking sleeve in a support structure, whereby the locking sleeve can not escape from the opening; and (S3) passing the locking sleeve and the support structure with a hinge pin.
Vorzugsweise werden vor dem Einschiebeschritt (S2) auch die anderen Bestandteile der Feststelleinrichtung in den Einsatz eingeführt. Die zentrale Bohrung der Feststellhülse, die ggfs. von der Öffnung umlaufend beabstandet ist, wird vorzugsweise mit Augen der Tragstruktur ausgefluchten positioniert, damit der Scharnierstift in einem Hub eingeführt werden und an seinem Ende vernietet werden kann. Da die Feststellhülse auf einen Abschnitt des Scharnierstift aufgepresst wird, kann entweder eine Positionierhilfe durch das Auge der Tragstruktur die Feststellhülse zentriert halten und beaufschlagen; bevorzugt wird aber ein Hilfsdorn ein Auge und die zentrale Bohrung der Feststellhülse gegenseitig fixieren, die auf die Feststellhülse wirkende Kraft zum Einpressen des Scharnierstifts wird mittelbar über die Tragstruktur auf diese übertragen, und beim Eindringen des Scharnierstifts wird der Dorn ausgestoßen oder herausgezogen.Preferably, the other components of the locking device are introduced into the insert before the insertion step (S2). The central bore of the locking sleeve, which is optionally circumferentially spaced from the opening, is preferably positioned aligned with eyes of the support structure so that the hinge pin can be inserted in a hub and riveted at its end. Since the locking sleeve is pressed onto a portion of the hinge pin, either a positioning aid through the eye of the support structure hold the locking sleeve centered and act upon; but preferred is an auxiliary mandrel an eye and fix the central bore of the locking sleeve mutually, the force acting on the locking sleeve force for pressing the hinge pin is indirectly transmitted via the support structure on this, and upon penetration of the hinge pin, the mandrel is ejected or pulled out.

In
Die erste Scharnierhälfte 10 umfasst eine als U-förmiges Metallblechbiegeteil ausgebildete Tragstruktur 11 und einen in die Tragstruktur 11 einführbaren Einsatz 12. Die Tragstruktur 11 umfasst eine Basis 110, von der jeweils um ca. 90 Grad abgewinkelt ein unterer Schenkel 112 und ein oberer Schenkel 114 abstehen. In der Basis 110 ist eine erste Durchbrechung 110a vorgesehen, die von dem Einsatz 12 bedeckt ist, und eine zweite Durchbrechung 110b, die benachbart und beabstandet zu dem Einsatz 12 vorgesehen ist. Die dem Einsatz 12 abgekehrte Seite der Basis 110 wird hierbei an die Anlagekante des Türrahmens 10a angelegt, und Befestigungsmittel wie Schrauben, Bolzen oder Niete durchsetzen die Durchbrechungen 110a, 110b, was nachstehend noch im Einzelnen näher erläutert wird. Die Tragstruktur 11 ist insgesamt winkelförmig ausgebildet, wobei der eine Schenkel des Winkels U-förmig gefaltet ist und in Erstreckungsrichtung der Basis 110 weist, und der andere Schenkel des Winkels ist durch die beiden Schenkel 112, 114 gebildet, vgl. insbesondere auch
Von den Schenkeln 112, 114 steht um 90 Grad abgewinkelt und eine Ebene senkrecht zu den Schenkeln 112, 114 und senkrecht zu der Basis 110 verschließend jeweils beidseitig ein um 90 Grad abgewinkelter Anschlag 112a, 114a, 112b, 114b vor, die paarweise eine seitliche Begrenzung für den Einsatz 12 bilden, die Anschläge 112a, 114a einerseits des Einsatzes 12 und die Anschläge 112b, 114b andererseits des Anschlags, vgl. insbesondere auch
Der Einsatz 12 ist aus einem - wahlweise transparentem oder opakem - Kunststoff im Spritzgussverfahren als einstückiges Teil hergestellt und weist einen quaderförmigen Abschnitt 120, der der Basis 110 zugekehrt ist, und einen auskragenden Abschnitt 121, der der Basis 110 abgekehrt ist, auf, die als einstückiges Spritzgussteil ausgebildet sind. Eine dem auskragenden Abschnitt 121 abgekehrte Stirnseite 120a des quaderförmigen Abschnitts 120 weist einen abgerundeten Übergang 120r zu den parallelen oberen und unteren Begrenzungsflächen 120b, 120c des quaderförmigen Abschnitts 120 und des auskragenden Abschnitts 121 des Einsatzes 12 auf, der an den Radius zwischen der Basis 110 und den Schenkeln 112, 114 angepasst ist. Die seitlichen Begrenzungsflächen 120d, 120e des quaderförmigen Abschnitts 120 sind derart beabstandet, dass diese sich zwischen den Anschlägen 112a, 114a einerseits und 112b, 114b andererseits einführen lassen, wobei auf Höhe der die Anschläge mit den Schenkeln 112, 114 verbindenden Metallabschnitte Ausnehmungen 122 in dem Einsatz 12 ausgespart sind, die ein Einrasten der Verbindungen zulassen und so ein formschlüssiges Fixieren des Einsatzes 12 in der Tragstruktur 11 ermöglichen.The
Der auskragende Abschnitt 121 des Einsatzes 12 weist eine die breiten Begrenzungsflächen 120b, 120c durchsetzende Öffnung 123 auf, die einen ersten Abschnitt 123a aufweist, der einen Radius um die strichpunktiert angedeutete Scharnierachse A aufweist, und einen zweiten Abschnitt 123b mit einem um ca. 40-60 % größeren Radius als der des ersten Abschnitts 123a, wobei der erste Abschnitt etwas mehr als 180 Grad und der zweite Abschnitt 123b etwas weniger als 180 Grad Öffnungswinkel ausmacht, wie aus der geschnittenen Darstellung gemäß
In dem Einsatz 12 ist eine Feststellanordnung 40 ganz oder zumindest überwiegend untergebracht. Die Feststellanordnung 40 umfasst eine Feststellhülse 41 mit einer zentralen Bohrung 41a und einem Feststellsegment 410, das nach Art eines Winkelsegments radial über den übrigen Umfang 41b der Feststellhülse 41 vorsteht. Die Feststellhülse 41 ist aus Stahl hergestellt und weist im Bereich ihrer zentralen Bohrung 41a eine Rändelung auf, die ein Verpressen auf einen Abschnitt 30a des Scharnierstifts 30 zulässt. Hierbei wird die äußere Umfangsfläche 41b in dem ersten Abschnitt 123a mit einem radialen Spalt aufgenommen, während das Feststellsegment 410 in dem zweiten Abschnitt 123b mit einem radialen Spalt aufgenommen ist.In the
Die beiden Schenkel 411, 412 des Feststellsegments 410 begrenzen die Verschwenkbarkeit der Feststellhülse 41 in der Öffnung 123, wenn diese gegen die in etwa auf die Scharnierachse gerichteten Ebenen oder Stufen 123c, 123d am Übergang des größeren Abschnitts 123b zum kleineren Abschnitts 123a anschlagen. Der Achse A abgekehrt sind in der radial von der Achse A nach außen weisenden Umfangsfläche 413 vier vertikale Nuten 413a eingelassen, die eine bevorzugte Rastposition des Bremsgliedes 42 der Feststelleinrichtung 40 ermöglichen, und so bevorzugte Öffnungswinkel der an das Scharnier 1 angeschlossenen Fahrzeugtür 20a einstellen.The two
Die Feststellanordnung 40 umfasst ferner ein Bremsglied 42, das von einem gegen eine Abstützung 43 abgestützten Federglied 44 in Richtung auf die Öffnung 123 in dem Führungskanal 124 vorgespannt ist, welche Teile 43, 44 ebenfalls in dem Führungskanal des Einsatzes 12 untergebracht sind. Zur Abdichtung sind an dem Bremsglied 42 bzw. an der Abstützung 43 jeweils radial O-Ringe 42a bzw. 43a aus Kunststoff in entsprechenden Nuten 42b des Bremsglieds 42 bzw. 43b der Abstützung 43 angeordnet. Das Bremsglied 42 weist einen der Öffnung 123 abgekehrten Zentrierstift 42c auf, der eine Unterlegscheibe 42d durchsetzt und den mittleren Hohlraum des als Schraubenfeder ausgebildeten Federglieds 44 eindringt. Das Federglied 44 ist gegen einen vorderen Teller der Abstützung 43 abgestützt und spannt das Bremsglied 42 in Richtung auf die Öffnung 123 innerhalb des Führungskanals 124 vor.
