Definitions
- the invention relates to a removable frame for a loader device, in particular for a front loader, telescopic loader, skid steer loader, swing loader, wheel loader or Hoflader.
- Front loaders, telehandlers, skid steers and others are loader devices intended to carry out batching, grading, shoveling, clearing, etc.
- the charger device has one or more pivotable arms on which or on which a working tool is attached.
- a front loader two booms are provided, which are usually coupled together by cross braces and can be raised and lowered by means of lifting cylinders.
- the telehandler has only one boom.
- a tilting movement of the tool at the end of the or the boom can be performed.
- the boom or arms can be provided variable in length in order to increase the radius of action for the tool.
- removable frame In order to equip the boom or arms modularly with different tools, are in the art used so-called removable frame.
- a removable frame is exemplary in the FIG. 1 shown and designated by the reference numeral 1 '.
- the removable frame 1 ' is coupled to the two arms 100' of a charger device, not shown.
- the removable frame 1 ' has a frame 2' on which a tool, not shown, such as a blade or a fork can be attached.
- the frame 2 ' has an upper and lower beam 3' and 4 ', which are connected to each other via side plates 5' and 6 'and together span the substantially rectangular frame 2'.
- To stabilize or reinforce the removable frame 1 'further struts can be provided, which in the FIG. 1 are indicated.
- the interchangeable frame 1 ' communicates with hydraulic devices 101' of the arms 100 'in connection with which a tilting movement of the interchangeable frame 1' and thus possibly a tool attached thereto about a substantially horizontal axis B 'can be realized
- the removable frame 1 'of FIG. 1 is connected to the one degree of freedom of pivoting about the horizontal axis B 'fixed to the arms 100. Furthermore, the removable frame 1 'on no further degrees of freedom for tilting, rotating or pivoting of the tool. In particular, with the conventional removable frame a lateral inclination compensation, such as an uneven load distribution or an inclination of the charger device in the field is not possible. Any flexibility of the tool is not necessarily desirable, since this usually requires technically complex structures that are maintenance-prone and can affect the robustness or stability.
- the US 5,562,398 describes a skid steer loader in which the tool, which is here a blade, can be rotated about a horizontal longitudinal axis in addition to the degree of freedom described above.
- the skid steer loader has two parallel boom, at the end of which there is a plate which is connected via a rotary member with the blade.
- the rotary shaft in the longitudinal direction is located centrally between the two arms and in the upper part of the plate.
- the rotation about the horizontal longitudinal axis takes place in the US 5,562,398 hydraulically and for the purpose of lateral tilting of material from the blade, whereby comparatively large tilt angles about the horizontal longitudinal axis can be realized.
- An object of the invention is to provide a removable frame for a charger device, which allows a side slope compensation of the charger device in a technically robust, compact, lightweight and low-maintenance manner.
- the interchangeable frame according to the invention is coupled or coupled to one or more arms of a loading device, such as a front loader, telescopic loader, skid steer loader, swing loader, wheel loader or Hoflader.
- the charger device is usually a vehicle, such as a tractor. Due to the position and position of the charger device in the state of use, the terms “right”, “left”, “top” and “bottom” are uniquely determined. Thus, the positions of a “horizontal longitudinal axis”, “horizontal plane”, “vertical plane”, “width direction”, “longitudinal direction”, etc. are also clearly determined.
- the removable frame is connected or connectable with a tool.
- the removable frame as a module for receiving and replacing different tools, such as for example, a shovel, a fork, etc. provided.
- the exchangeable frame is pivotable about a horizontal axis in the width direction of the loading device relative to the cantilever and the cantilevers, respectively.
- the removable frame according to the invention has a mechanism for tilting the tool about a compensating axis.
- the compensating axis extends substantially horizontally and in the longitudinal direction with respect to the loading device.
- the removable frame additionally permits tilting about the longitudinal axis.
- the compensation axis is offset to the right or left from a vertical plane which intersects the center of gravity of the removable frame.
- the compensation axis is thus not in a plane which bisects the rectangle symmetrically in the vertical direction.
- the compensation axis is thus offset laterally, to the right or left of the center of the removable frame. Due to the lateral position of the pivot point for pivoting about the compensation axis of the desired lateral inclination compensation is accomplished with little force. A central pivot point would require considerable design effort to stabilize the rotation, especially in the case of large and very unevenly distributed loads.
- the interchangeable frame of the invention has a low weight and avoids a significant visual obstruction, which would be present in the case of a central pivot point.
- the lateral displacement of the fulcrum and the associated advantages are, among other things, therefore technically useful, because for the purpose of side slope compensation no very large swivel angle must be achieved.
- the compensation axis intersects the removable frame in the lower area.
- the compensation axis intersects the rectangle in the lower half with respect to a horizontal bisector, preferably the compensation axis intersects the change frame in the vicinity or directly on the lower side.
- the compensation axis preferably extends substantially through a lower corner of the frame. It is further preferred that the compensation axis is substantially perpendicular to the rectangle.
- the degree of lateral inclination compensation to be made depends not only on the position of the loading device in the field and on the load distribution on the tool, but also on the position of the boom (s) and the tilting angle about the horizontal axis in the width direction. Depending on the position of the boom and the conventional tilt angle leads a lateral inclination compensation to the compensating axis, possibly also to an undesirable rotation about one or more other axes. For this reason, the tilting about the compensation axis can be accomplished so that not desired rotation angle can be compensated.
- the compensation axis is not exactly perpendicular to the removable frame or the plane spanned by the removable frame level. Rather, deviations by a few degrees are possible.
- the position of the compensation axis relative to the removable frame may even change depending on the tilt angle about the compensation axis.
- the tilting about the compensating axis is effected via a hydraulic actuating means.
- one or more hydraulic cylinders can be provided, the or which is preferably provided on the compensation axis of the opposite side of the removable frame or, with respect to the vertical plane which intersects the center of gravity of the removable frame.
- the adjustment of the tilt angle about the compensating axis can be done manually or automatically, in particular electronically.
- a sensor may be provided which measures the inclination of the loading device in the field and / or the load distribution on the tool and then adjusts the optimal tilt angle about the compensating axis.
- the removable frame on a rail and a roller, which cooperate technically to guide the tilting movement about the compensating axis.
- the rail and the roller are provided on two parts of the removable frame, which are pivotable relative to each other about the compensation axis.
- the rail and the roller are preferably located on the opposite side of the compensating axis of the removable frame, with respect to the vertical plane which intersects the center of gravity of the removable frame.
- the rail and the roller are located as far as possible on the lateral edge of the removable frame, which is opposite to the edge on which the compensation axis is located.
- the rail is preferably curved along a contour that corresponds to the tilting movement about the compensating axis. In other words, the rail preferably describes approximately a circular arc around the compensation axis.
- a guiding means and a guided means are provided, which cooperate technically to stabilize the tilting movement about the compensation axis.
- roller and rail are mentioned for the sake of simplicity, the corresponding features can be applied generally to the guide means and the guided means.
- the guide means may be curved as described above and below.
- the rail is also curved in a direction that is not in the plane of the above circular arc, or more generally, is not in the plane perpendicular to the balance axis.
- the curvature along such additional direction is intended to compensate for rotations about "unwanted" axes of rotation that may occur depending on the location of the tool, as described above. If such a compensation is to take place, the position of the compensation axis is variable as a function of the pivoting angle about the same.
- Such mobility can be realized for example via a ball joint at the pivot point on the compensation axis.
- the removable frame is intended and suitable for use with a front loader or telehandler.
- a side slope compensation of the type described above is desirable.
- the side tilt compensation mechanism can be made in a technically simple, robust, lightweight and low maintenance manner, without significant obstruction, without requiring constructive adjustment of the loader device and / or the tool.
- the FIG. 2 shows a removable frame 1, which is attached to two arms 100 of a loading device, not shown beyond.
- the removable frame 1 has a rectangular frame 2, which in turn is composed of an upper 3 and lower 4 spar and a right 5 and left 6 side plate and spans a rectangle.
- Other elements for stabilizing or reinforcing the removable frame 1, such as struts can be provided and are in the FIG. 2 indicated, but unspecified.
- the removable frame 1 is attached via hydraulic cylinder 101 to the arms 100, so that the removable frame 1 to a horizontal axis in the width direction B can be tilted forward and backward.
- the removable frame 1 can be tilted about a compensating axis A, which is approximately perpendicular to the rectangle that is spanned by the frame 2.
- the removable frame 1 is shown in three positions to show the lateral tilting movement about the compensating axis A.
- the pivot point of this tilting movement is located approximately in the lower left corner of the frame 2 spanned by the rectangle.
- the fulcrum is thus offset laterally from a vertical plane which intersects the center of gravity of the removable frame 1.
- the here mentioned vertical plane is in the FIG. 2 not shown; it stands vertically on the frame 2 and bisects it in the vertical direction.
- the emphasis here is on the geometric center of gravity of the frame 2.
- An actuating means for pivoting the frame 2 about the compensating axis A such as a hydraulic cylinder is provided, but in the FIG. 2 for the sake of clarity not shown.

Description
Die Erfindung betrifft einen Wechselrahmen für eine Ladervorrichtung, insbesondere für einen Frontlader, Teleskoplader, Kompaktlader, Schwenklader, Radlader oder Hoflader.The invention relates to a removable frame for a loader device, in particular for a front loader, telescopic loader, skid steer loader, swing loader, wheel loader or Hoflader.
Frontlader, Teleskoplader, Kompaktlader und andere sind Ladervorrichtung, die zur Verrichtung von Stapelarbeiten, Planierarbeiten, Schaufelarbeiten, Räumarbeiten usw. vorgesehen sind. Hierzu weist die Ladervorrichtung einen oder mehrere schwenkbare Ausleger auf, an dem bzw. an denen ein Arbeitswerkzeug befestigt ist.Front loaders, telehandlers, skid steers and others are loader devices intended to carry out batching, grading, shoveling, clearing, etc. For this purpose, the charger device has one or more pivotable arms on which or on which a working tool is attached.
Im Falle eines Frontladers sind zwei Ausleger vorgesehen, die üblicherweise über Querstreben miteinander gekoppelt sind und mittels Hubzylindern angehoben und abgesenkt werden können. Im Unterschied zum Frontlader weist der Teleskoplader nur einen Ausleger auf. Mittels einer oder mehrerer Stelleinrichtungen kann eine Kippbewegung des Werkzeugs am Ende des oder der Ausleger durchgeführt werden. Ferner ist bekannt, dass der oder die Ausleger in der Länge veränderbar vorgesehen sein können, um den Aktionsradius für das Werkzeug zu vergrößern.In the case of a front loader two booms are provided, which are usually coupled together by cross braces and can be raised and lowered by means of lifting cylinders. Unlike the front loader, the telehandler has only one boom. By means of one or more adjusting devices, a tilting movement of the tool at the end of the or the boom can be performed. Furthermore, it is known that the boom or arms can be provided variable in length in order to increase the radius of action for the tool.

Eine Aufgabe der Erfindung besteht darin, einen Wechselrahmen für eine Ladervorrichtung bereitzustellen, der einen Seitenneigungsausgleich der Ladervorrichtung auf technisch robuste, kompakte, leichtgewichtige und wartungsarme Weise ermöglicht.An object of the invention is to provide a removable frame for a charger device, which allows a side slope compensation of the charger device in a technically robust, compact, lightweight and low-maintenance manner.
Die Aufgabe wird mit einem Wechselrahmen gemäß Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen folgen aus den Unteransprüchen.The object is achieved with a removable frame according to claim 1. Advantageous embodiments follow from the subclaims.
Der Wechselrahmen gemäß der Erfindung ist mit einem oder mehreren Auslegern einer Ladervorrichtung, etwa einem Frontlader, Teleskoplader, Kompaktlader, Schwenklader, Radlader oder Hoflader gekoppelt oder koppelbar. Die Ladervorrichtung ist üblicherweise ein Fahrzeug, etwa ein Traktor. Durch die Position und Lage der Ladervorrichtung im Benutzungszustand sind die Bezeichnungen "rechts", "links", "oben" und "unten" eindeutig bestimmt. Damit sind auch die Lagen einer "horizontalen Längsachse", "horizontalen Ebene", "vertikalen Ebene", "Breitenrichtung", "Längsrichtung" usw. eindeutig bestimmt.The interchangeable frame according to the invention is coupled or coupled to one or more arms of a loading device, such as a front loader, telescopic loader, skid steer loader, swing loader, wheel loader or Hoflader. The charger device is usually a vehicle, such as a tractor. Due to the position and position of the charger device in the state of use, the terms "right", "left", "top" and "bottom" are uniquely determined. Thus, the positions of a "horizontal longitudinal axis", "horizontal plane", "vertical plane", "width direction", "longitudinal direction", etc. are also clearly determined.
Der Wechselrahmen ist mit einem Werkzeug verbunden oder verbindbar. Insbesondere ist der Wechselrahmen als Modul zur Aufnahme und zum Auswechseln verschiedener Werkzeuge, wie beispielsweise einer Schaufel, einer Gabel usw. vorgesehen. Außerdem ist der Wechselrahmen wie herkömmlich vorzugsweise um eine horizontale Achse in Breitenrichtung der Ladervorrichtung relativ zu dem Ausleger bzw. den Auslegern schwenkbar bzw. kippbar.The removable frame is connected or connectable with a tool. In particular, the removable frame as a module for receiving and replacing different tools, such as for example, a shovel, a fork, etc. provided. In addition, as is conventional, preferably, the exchangeable frame is pivotable about a horizontal axis in the width direction of the loading device relative to the cantilever and the cantilevers, respectively.
Darüber hinaus weist der erfindungsgemäße Wechselrahmen einen Mechanismus zum Kippen des Werkzeugs um eine Ausgleichsachse auf. Die Ausgleichsachse verläuft bezüglich der Ladervorrichtung im Wesentlichen horizontal und in Längsrichtung. Mit anderen Worten ermöglicht der Wechselrahmen neben dem bevorzugten herkömmlichen Kippen des Werkzeugs um die horizontale Achse in Breitenrichtung zusätzlich ein Kippen um die Längsachse.In addition, the removable frame according to the invention has a mechanism for tilting the tool about a compensating axis. The compensating axis extends substantially horizontally and in the longitudinal direction with respect to the loading device. In other words, in addition to the preferred conventional tilting of the tool about the horizontal axis in the width direction, the removable frame additionally permits tilting about the longitudinal axis.
Erfindungsgemäß ist die Ausgleichsachse von einer vertikalen Ebene, welche den Schwerpunkt des Wechselrahmens schneidet, nach rechts oder links versetzt. In dem Fall, in dem der Wechselrahmen ein Rechteck aufspannt, liegt die Ausgleichsachse somit nicht in einer Ebene, welche das Rechteck in vertikaler Richtung symmetrisch halbiert. Die Ausgleichsachse ist somit seitlich, nach rechts oder links von der Mitte des Wechselrahmens versetzt. Durch die seitliche Lage des Drehpunkts für das Schwenken um die Ausgleichsachse wird der gewünschte Seitenneigungsausgleich mit geringer Kraft bewerkstelligt. Ein zentraler Drehpunkt würde einen erheblichen konstruktiven Aufwand zur Stabilisierung der Drehung erfordern, insbesondere im Falle großer und sehr ungleich verteilten Lasten. Der Wechselrahmen der Erfindung weist ein geringes Gewicht auf und vermeidet eine erhebliche Sichtbehinderung, die im Falle eines zentralen Drehpunkts vorhanden wäre. Die seitliche Versetzung des Drehpunkts und die damit verbundenen Vorteile sind unter anderem auch deshalb technisch sinnvoll, weil für den Zweck des Seitenneigungsausgleichs keine ausgesprochen großen Schwenkwinkel erzielbar sein müssen.According to the invention, the compensation axis is offset to the right or left from a vertical plane which intersects the center of gravity of the removable frame. In the case in which the removable frame spans a rectangle, the compensation axis is thus not in a plane which bisects the rectangle symmetrically in the vertical direction. The compensation axis is thus offset laterally, to the right or left of the center of the removable frame. Due to the lateral position of the pivot point for pivoting about the compensation axis of the desired lateral inclination compensation is accomplished with little force. A central pivot point would require considerable design effort to stabilize the rotation, especially in the case of large and very unevenly distributed loads. The interchangeable frame of the invention has a low weight and avoids a significant visual obstruction, which would be present in the case of a central pivot point. The lateral displacement of the fulcrum and the associated advantages are, among other things, therefore technically useful, because for the purpose of side slope compensation no very large swivel angle must be achieved.
Vorzugsweise schneidet die Ausgleichsachse den Wechselrahmen im unteren Bereich. In dem oben beschriebenen Fall, in dem der Ausgleichsrahmen ein Rechteck aufspannt, schneidet die Ausgleichsachse das Rechteck in der unteren Hälfte bezüglich einer horizontalen Halbierenden, bevorzugt schneidet die Ausgleichsachse den Wechselrahmen in der Nähe oder direkt an der unteren Seite. Dadurch kann der Bewegungsradius des Werkzeugs beim Kippen um die Ausgleichsachse klein gehalten werden, was für den Zweck des Seitenneigungsausgleichs besonders vorteilhaft ist.Preferably, the compensation axis intersects the removable frame in the lower area. In the case described above, in which the balance frame spans a rectangle, the compensation axis intersects the rectangle in the lower half with respect to a horizontal bisector, preferably the compensation axis intersects the change frame in the vicinity or directly on the lower side. As a result, the radius of movement of the tool when tilting about the compensating axis can be kept small, which is particularly advantageous for the purpose of lateral inclination compensation.
In dem Fall, in dem der Wechselrahmen ein Rechteck aufspannt, verläuft die Ausgleichsachse vorzugsweise im Wesentlichen durch eine untere Ecke des Rahmens. Ferner ist bevorzugt, dass die Ausgleichsachse im Wesentlichen senkrecht auf dem Rechteck steht. Der Grad des herzustellenden Seitenneigungsausgleichs hängt nicht nur von der Lage der Ladervorrichtung im Gelände und von der Lastverteilung am Werkzeug ab, sondern auch von der Stellung des bzw. der Ausleger und vom Kippwinkel um die horizontale Achse in Breitenrichtung. In Abhängigkeit der Lage der Ausleger und des herkömmlichen Kippwinkels führt ein Seitenneigungsausgleich um die Ausgleichsachse ggf. auch zu einer unerwünschten Drehung um eine oder mehrere andere Achsen. Aus diesem Grund kann das Kippen um die Ausgleichsachse so bewerkstelligt werden, dass nicht gewünschte Drehwinkel kompensiert werden. Dies kann dadurch erzielt werden, dass die Ausgleichsachse nicht exakt senkrecht auf dem Wechselrahmen bzw. der vom Wechselrahmen aufgespannten Ebene stehen. Vielmehr sind Abweichungen um einige Grad möglich. Die Lage der Ausgleichsachse relativ zum Wechselrahmen kann sich sogar in Abhängigkeit vom Kippwinkel um die Ausgleichsachse ändern.In the case in which the removable frame spans a rectangle, the compensation axis preferably extends substantially through a lower corner of the frame. It is further preferred that the compensation axis is substantially perpendicular to the rectangle. The degree of lateral inclination compensation to be made depends not only on the position of the loading device in the field and on the load distribution on the tool, but also on the position of the boom (s) and the tilting angle about the horizontal axis in the width direction. Depending on the position of the boom and the conventional tilt angle leads a lateral inclination compensation to the compensating axis, possibly also to an undesirable rotation about one or more other axes. For this reason, the tilting about the compensation axis can be accomplished so that not desired rotation angle can be compensated. This can be achieved in that the compensation axis is not exactly perpendicular to the removable frame or the plane spanned by the removable frame level. Rather, deviations by a few degrees are possible. The position of the compensation axis relative to the removable frame may even change depending on the tilt angle about the compensation axis.
Vorzugsweise wird das Kippen um die Ausgleichsachse über ein hydraulisches Betätigungsmittel bewirkt. Hierzu kann ein oder können mehrere Hydraulikzylinder vorgesehen sein, der bzw. die vorzugsweise auf der der Ausgleichsachse gegenüberliegenden Seite des Wechselrahmens vorgesehen ist bzw. sind, bezüglich der vertikalen Ebene, welche den Schwerpunkt des Wechselrahmens schneidet. In diesem Zusammenhang sei darauf hingewiesen, dass die Einstellung des Kippwinkels um die Ausgleichsachse manuell oder automatisch, insbesondere elektronisch erfolgen kann. Beispielsweise kann ein Sensor vorgesehen sein, der die Schrägstellung der Ladervorrichtung im Gelände und/oder die Lastenverteilung am Werkzeug misst und daraufhin den optimalen Kippwinkel um die Ausgleichsachse einstellt.Preferably, the tilting about the compensating axis is effected via a hydraulic actuating means. For this purpose, one or more hydraulic cylinders can be provided, the or which is preferably provided on the compensation axis of the opposite side of the removable frame or, with respect to the vertical plane which intersects the center of gravity of the removable frame. In this context, it should be noted that the adjustment of the tilt angle about the compensating axis can be done manually or automatically, in particular electronically. For example, a sensor may be provided which measures the inclination of the loading device in the field and / or the load distribution on the tool and then adjusts the optimal tilt angle about the compensating axis.
Vorzugsweise weist der Wechselrahmen eine Schiene und eine Rolle auf, die technisch zusammenwirken, um die Kippbewegung um die Ausgleichsachse zu führen. Die Schiene und die Rolle sind an zwei Teilen des Wechselrahmens vorgesehen, die gegeneinander um die Ausgleichsachse schwenkbar sind. Hierbei befinden sich die Schiene und die Rolle vorzugsweise auf der der Ausgleichsachse gegenüberliegenden Seite des Wechselrahmens, bezüglich der vertikalen Ebene, welche den Schwerpunkt des Wechselrahmens schneidet. Insbesondere ist es bevorzugt, dass sich die Schiene und die Rolle möglichst weit am seitlichen Rand des Wechselrahmens befinden, der dem Rand, an dem sich die Ausgleichsachse befindet, gegenüberliegt. Die Schiene ist hierbei vorzugsweise entlang einer Kontur gekrümmt, die der Kippbewegung um die Ausgleichsachse entspricht. Mit anderen Worten beschreibt die Schiene vorzugsweise ungefähr einen Kreisbogen um die Ausgleichsachse.Preferably, the removable frame on a rail and a roller, which cooperate technically to guide the tilting movement about the compensating axis. The rail and the roller are provided on two parts of the removable frame, which are pivotable relative to each other about the compensation axis. Here, the rail and the roller are preferably located on the opposite side of the compensating axis of the removable frame, with respect to the vertical plane which intersects the center of gravity of the removable frame. In particular, it is preferred that the rail and the roller are located as far as possible on the lateral edge of the removable frame, which is opposite to the edge on which the compensation axis is located. The rail is preferably curved along a contour that corresponds to the tilting movement about the compensating axis. In other words, the rail preferably describes approximately a circular arc around the compensation axis.
Alternativ kann die Führung der Kippbewegung mittels eines Langlochs und eines Stifts, einer Nut/Feder-Konstruktion, eines Drehkreuzes, einer Lenkerkonstruktion, einer Hebelkonstruktion ggf. aus mehreren sich parallel verschiebenden oder drehenden Holmen oder anders bewerkstelligt werden. Allgemein gesprochen sind vorzugsweise somit ein Führungsmittel und ein geführtes Mittel vorgesehen, die technisch zusammenwirken, um die Kippbewegung um die Ausgleichsachse zu stabilisieren. Wenn oben und im Folgenden der Einfachheit halber von Rolle und Schiene die Rede ist, können die entsprechenden Merkmale allgemein für das Führungsmittel und das geführte Mittel angewendet werden. Insbesondere kann das Führungsmittel wie oben und im Folgenden beschrieben gekrümmt sein.Alternatively, the leadership of the tilting movement by means of a slot and a pin, a tongue / groove construction, a turnstile, a handlebar construction, a lever construction, if necessary, from several parallel shifting or rotating spars or otherwise accomplished. Generally speaking, preferably a guiding means and a guided means are provided, which cooperate technically to stabilize the tilting movement about the compensation axis. If, above and below, the term roller and rail are mentioned for the sake of simplicity, the corresponding features can be applied generally to the guide means and the guided means. In particular, the guide means may be curved as described above and below.
Vorzugsweise ist die Schiene auch in einer Richtung gekrümmt, die nicht in der Ebene des obigen Kreisbogens liegt, oder allgemeiner gesprochen, nicht in der Ebene liegt, die senkrecht auf der Ausgleichsachse steht. Die Krümmung entlang einer solchen Zusatzrichtung ist vorgesehen, wenn eine Kompensation von Drehungen um "nicht gewollte" Drehachsen bewerkstelligt werden soll, die in Abhängigkeit von der Lage des Werkzeugs stattfinden können, wie es oben beschrieben ist. Wenn eine solche Kompensation stattfinden soll, ist die Lage der Ausgleichsachse in Abhängigkeit des Schwenkwinkels um selbige veränderlich. Eine solche Beweglichkeit kann beispielsweise über ein Kugelgelenk am Drehpunkt auf der Ausgleichsachse realisiert werden.Preferably, the rail is also curved in a direction that is not in the plane of the above circular arc, or more generally, is not in the plane perpendicular to the balance axis. The curvature along such additional direction is intended to compensate for rotations about "unwanted" axes of rotation that may occur depending on the location of the tool, as described above. If such a compensation is to take place, the position of the compensation axis is variable as a function of the pivoting angle about the same. Such mobility can be realized for example via a ball joint at the pivot point on the compensation axis.
Vorzugsweise ist der Wechselrahmen zur Verwendung mit einem Frontlader oder Teleskoplader vorgesehen und geeignet. Insbesondere für Frontlader und Teleskoplader, aber auch für Kompaktlader und andere ist ein Seitenneigungsausgleich der oben beschriebenen Art wünschenswert. Indem der Mechanismus zum Seitenneigungsausgleich im Wechselrahmen integriert ist, kann der Seitenneigungsausgleich auf technisch einfache, robuste, leichte und wartungsarme Art und Weise, ohne erhebliche Sichtbehinderung, vorgenommen werden, ohne dass eine konstruktive Anpassung der Ladervorrichtung und/oder des Werkzeugs erforderlich ist.Preferably, the removable frame is intended and suitable for use with a front loader or telehandler. Especially for front loader and telescopic loaders, but also for skid steers and others a side slope compensation of the type described above is desirable. By incorporating the side tilt compensation mechanism in the interchangeable frame, the side tilt compensation can be made in a technically simple, robust, lightweight and low maintenance manner, without significant obstruction, without requiring constructive adjustment of the loader device and / or the tool.

Die oben dargestellten beispielhaften Ausführungsformen realisieren die Erfindung auf technisch robuste und wartungsarme Art und Weise. Zudem sind die gezeigten Wechselrahmen vergleichsweise leicht und werden über einen technisch besonders einfachen Betätigungsmechanismus betätigt, was insbesondere deshalb möglich ist, weil die Ausgleichsachse nicht zentral bezüglich des Wechselrahmens vorgesehen ist, sondern seitlich versetzt.The exemplary embodiments presented above realize the invention in a technically robust and low-maintenance manner. In addition, the removable frame shown are relatively easy and are actuated by a technically particularly simple operating mechanism, which is particularly possible because the compensation axis is not centrally provided with respect to the removable frame, but laterally offset.
Der hier dargestellte Seitenneigungsausgleich ist für Radlader (Schaufellader), Frontlader (für Schlepper, Zugmaschinen), Teleskoplader, Schwenklader, Kompaktlader und Hoflader mit Hubschwinge oder Hubarm (der oder die auch seitlich versetzt sein können) mit oder ohne Teleskopeinheit geeignet.The lateral inclination compensation system shown here is suitable for wheel loaders (loaders), front loaders (for tractors, tractors), telescopic loaders, swing loaders, skid steer loaders and reciprocating loaders (which can also be laterally offset) with or without telescopic unit.
Der Mechanismus zum Seitenneigungsausgleich ist Teil des Wechselrahmens oder an diesem vorgesehen. Dadurch ist es nicht erforderlich, dass die Werkzeuge und/oder Ausleger der Ladervorrichtung auf besondere Weise für diese zusätzliche Funktionalität angepasst werden. Durch die vergleichsweise geringe Neigungsbewegung (eine sehr große Neigungsbewegung ist für den hier beschriebenen Seitenneigungsausgleich nicht erforderlich) ist eine sehr kompakte Bauweise mit geringem Zusatzgewicht realisierbar. Darüber hinaus kann die zusätzliche Funktionalität des Seitenneigungsausgleichs preiswert hergestellt werden, sie ist unempfindlich gegen Schmutz und äußerst langlebig. Eine hydraulische Betätigung ist bevorzugt.The lateral tilt compensation mechanism is part of or provided on the removable frame. Thereby, it is not necessary that the tools and / or arms of the charger device in a special way for this additional Functionality to be adjusted. Due to the comparatively low inclination movement (a very large inclination movement is not required for the lateral inclination compensation described here), a very compact design with low additional weight can be realized. In addition, the additional functionality of the side tilt compensation can be produced inexpensively, it is insensitive to dirt and extremely durable. Hydraulic actuation is preferred.
