Description
Technical Field
The present invention relates to a disc brake, in particular for a motor vehicle, and to a method for producing such a disc brake.
Background
In this case, the invention comprises a disc brake having a sliding caliper or a fixed caliper and covering one or more brake discs. The present invention relates generally, but not exclusively, to a part-pad disc brake.
Different embodiments of disc brakes, in particular for heavy-duty trucks, are known, which relate not only to the type of brake operating mechanism, the type and manner in which the braking force is transmitted to one or more brake discs, but also to the manner in which the adjustment for compensating for the wear of the brake linings is carried out.
One particular embodiment of a brake operating device for use in a disc brake is disclosed, for example, by the present inventors' international patent application WO 2011/113554 A2. The brake operating mechanism known from this application is characterized by the most compact construction with a smaller space requirement and a lighter weight in the caliper housing. All the components of the brake operating mechanism are functionally cooperatively mounted in the brake caliper by means of a lever axially mounted in the housing of the brake caliper such that they operate parallel to the brake disc axis of rotation. Because of the displacement movement of the force-increasing mechanism, the pressure-exerting element together with the adjusting device performs a translational movement towards the brake disk in order to transmit the pressing force.
For an accurate manner of operation in respect of the supply and transmission of braking forces and readjustment movements in the brake operating mechanisms disclosed in the prior art, reference is explicitly made to the disclosure of WO 2011/113554 A2. Other similarly conceived brake operating mechanisms are disclosed, for example, by the inventors' WO 2013/083857 A2, WO 2014/106672 A2 or WO 2015/140225 A2, to which reference is also explicitly made.
WO 2018/015565 A1 of the present inventor, for example, also shows another brake operating mechanism of the aforementioned type in which a plurality of components are arranged around the lever and assembled by means of the lever into one preassembled unit.
A common advantage of all the aforementioned brake actuating mechanisms is that they can be mounted in the housing of the brake caliper by means of a lever as a preassembled unit. In the prior art, as shown for example in the sectional view of fig. 1, for this purpose, for example, a lock nut is attached to the external thread of the lever from the outside of the housing of the brake caliper, whereby a wedge in a rear part of the housing of the brake caliper, i.e. in a correspondingly configured opening opposite the brake caliper, is clamped, whereby the brake actuating mechanism is to be fixed in the housing of the brake caliper.
Disclosure of Invention
In view of this, the present invention is based on the task of further simplifying the installation of such a brake operating mechanism in which a lever is employed to position and fix some of its components for installation and/or to perform a certain function.
This object is achieved by a disk brake and a method for producing a disk brake.
In a first aspect, the invention therefore relates to a disc brake having a brake caliper which clamps at least one brake disc and a brake actuating mechanism which has:
A force-increasing mechanism for introducing a pressing force,
An adjusting device for compensating for lining wear with a torque clutch,
A pressure piece for transmitting a pressing force to a brake disk, and
The device is reset and the device is reset,
The force-increasing mechanism, the adjusting device, the pressure element and the restoring device are functionally and cooperatively mounted in the brake caliper by means of a lever which is mounted in an axially immovable manner in the housing of the brake caliper, wherein the force-increasing mechanism has a lever which is rotatably mounted on at least one eccentric bearing structure which extends transversely to the lever and which is fixedly connected to the housing of the brake caliper, and wherein the lever can be connected to the eccentric bearing structure by means of at least one preferably detachable device.
The eccentric bearing structure is generally realized in the form of at least one eccentric roller or cylinder, at least one partial cylinder, on which the lever of the force-increasing mechanism is rotatably supported. The lever is designed and constructed in such a way with respect to the at least one eccentric roller that, during a rotational movement about the eccentric roller, the eccentric displacement of the lever with respect to the eccentric roller is adjusted, which ultimately results in the force of the lever introduced by the actuator being increased before being transmitted further to the brake disk as a pressing force via other components of the brake actuating mechanism, in particular subsequently by the pressing element. The eccentric displacement is achieved in that the axis of the cylinder coincides with the center of the internal concave rotary support surface of the lever, while the center of the external convex rotary support surface of the lever is displaced relative to the center of the concave rotary support surface relative to the force-transmitting member of the brake actuating mechanism. With regard to the exact design and working of such an eccentric support structure of the lever, reference is made to the disclosure of the above-mentioned international patent application or of the inventor's international patent application WO 2004/027281 A2, the disclosure of which is hereby expressly referred to.
The lever is used to mount the brake elements of the brake actuating mechanism in the brake caliper housing in such a way that they operate parallel to the axis of rotation of the brake disc, wherein the lever is designed such that the brake elements are supported and held on the one hand on the lever and on the other hand in the region of the brake caliper rear housing facing away from the brake disc in different modular units and/or the brake actuating mechanism as a whole as an at least partially preassemblable unit that is always self-supporting. The disclosure of the above-mentioned international patent application should also be explicitly referred to regarding the way in which the lever works and the associated brake operating mechanism or parts thereof are installed as a pre-assembled unit.
The core of the invention is that the eccentric bearing structure or at least one eccentric roller is fixedly connected, preferably threadably connected, to the housing of the brake caliper, wherein the screw can be screwed from outside the rear housing part and through a corresponding bore, which is optionally internally threaded and can be penetrated.
The eccentric roller is thereby fixed in position and fixed in a rotationally fixed manner on the inner side of the housing, wherein the housing can have a correspondingly dimensioned concave cylinder inner surface for receiving and accommodating the eccentric roller.
At the same time, according to the invention, the entire brake actuating mechanism, which is held together as a self-supporting unit by means of a rod, is fastened to the rod by at least one device. In other words, by fixing the eccentric bearing structure or eccentric roller to the rear inner housing part of the brake caliper by means of a fixing device, such as a screw, the entire self-supporting unit of the brake actuating mechanism, including the eccentric bearing structure, is fixed in its operating position in the brake caliper housing.
For this purpose, the eccentric support structure or column may according to the invention have a receptacle for the device extending transversely to the rod. The device can preferably be embodied as a pin which is inserted into the receptacle in such a way that the brake actuating mechanism is held together with the eccentric support structure as a preassembled unit and is thus easy to handle. The pin is passed through a corresponding hole in the rod for this purpose.
The dimensions and tolerances of the recesses in the eccentric roller and of the holes in the lever and of the pins are selected such that a press fit is formed between them which is sufficient to withstand the forces occurring in such brake actuating mechanisms without separation, in particular without the shaking load caused by the driving of the vehicle, and which can be separated mechanically at any time for the removal of the brake actuating mechanism.
If the entire unit is secured to the rod by means of the pin or any other suitable mechanism, the unit may be screwed into or with the caliper housing by means of an eccentric roller by inserting corresponding bolts from the outside into holes in the housing and in the eccentric roller.
In one embodiment of the eccentric bearing structure according to the invention, the holes are arranged such that the securing means or pins are axially aligned with, i.e. intersect, the cylinder axis of the eccentric roller.
In a preferred embodiment of the disk brake, the device is designed as a nut which is accommodated in a recess of the eccentric bearing structure and screwed onto the rear-side threaded portion of the lever, preferably in such a way that the brake actuating mechanism can be actuated as a preassembled unit together with the eccentric bearing structure.
For this purpose, the recess of the eccentric bearing structure can have, at least in part, in the axial direction, a complementarily shaped abutment surface against which the nut abuts with its corresponding surface.
In particular, the eccentric bearing structure can have a further recess opposite the recess for the nut, into which the correspondingly formed shoulder of the rod can be inserted at least in part in a complementary manner. Thereby ensuring that the eccentric roller is positioned in a functionally accurate manner on the rod.
By means of the solution according to the invention, the installation of such a brake actuating mechanism is significantly simplified, since only a simple screw-fastening is required to fix the entire brake actuating mechanism, which can be produced by means of a defined holding torque if necessary. In addition, the solution of the invention increases the rigidity of the brake caliper, since there is no through hole for the lever that has to be provided in the rear housing part of large dimensions as in the prior art. The necessity of further measures for sealing such holes is obviated.
In addition, the invention relates in another aspect to a method for producing a disk brake having a brake caliper which clamps at least one brake disk and a brake actuating mechanism which has:
a force-increasing mechanism for the incoming compression force,
An adjusting device for compensating for lining wear with a torque clutch,
A pressing element for transmitting a pressing force to the brake disc, and
The device is reset and the device is reset,
Wherein the force-increasing means, the adjusting device, the pressure element and the restoring device are functionally and cooperatively mounted in the brake caliper by means of at least one lever which is not axially movably mounted in the housing of the brake caliper, wherein the force-increasing means has a lever which is rotatably mounted on at least one eccentric bearing structure which extends transversely to the lever,
The method comprises the following steps:
-fixing the eccentric support structure to the rod by at least one means in the case of forming the brake operating mechanism as a pre-assembled unit, and
-Fixing the pre-assembled unit in the housing of the brake caliper by inserting at least one fixing means cooperating with the eccentric support structure through the housing from outside the housing of the brake caliper.
The fastening means, for example bolts, can be inserted from outside the brake caliper housing, wherein a plurality of holes are provided in the housing at corresponding points, which preferably are aligned exactly with the cylinder axis of the roller body of the eccentric bearing structure.
However, the holes are also provided on both sides of the rod in the axial direction of the rod, obliquely with respect to the rod, transversely to the rod and/or laterally to the column, whereby the availability of installation space and also the requirements are taken into account. But preferably there are two holes or bolts on either side of the rod and oriented parallel to its axial direction, which are arranged on the same plane below the rod extending generally above the cylinder axis but aligned with the cylinder axis, so as to be effective against the corresponding leverage caused by the lever rotation during braking operations.

Detailed Description
Fig. 1 shows a brake actuating mechanism of the type known, for example, from international patent application WO 2011/113554 A2 of the present inventor in a sectional view.
All components of the brake actuating mechanism, namely the adjusting device, the pressure piece and the return device, are arranged on the same lever 1. Similarly, the lever 1 is provided with a force increasing mechanism for increasing the braking force transmitted from the actuator. The force-increasing means is realized such that the lever 2 is mounted eccentrically and rotatably on the cylinder or eccentric roller 3, whereby, when the lever 2 is rotated, an eccentric displacement is adjusted, which correspondingly increases the force and transmits the force into the adjusting device by means of the force-transmitting element 4.
The lever 1 and thus the brake actuating mechanism is fixed in the rear part of the housing 5 of the brake caliper in the mounted state in such a way that the lever 1 passes through a conically outwardly enlarged opening 6 in this part, so that the external thread of the lever 1 can receive a locking nut 7 which, with a sealing ring 9 interposed, clamps a wedge ring 8 in the opening 6, whereby the lever 1 and thus the brake actuating mechanism is fixedly held in the rear part of the housing 5 of the brake caliper.
Fig. 2 to 4 show a first embodiment of a disk brake according to the invention together with its main components, wherein fig. 2 shows an exploded view and fig. 3 and 4 each show an assembled state.
The brake actuating mechanism has a force-increasing mechanism a, an adjusting device B and a resetting device C, and a pressure piece, which is not shown in detail. For an accurate manner of operation of such a brake actuating mechanism reference should be made, for example, to the disclosure of the inventor's international patent application WO 2018/015565 A1.
The force-increasing means a has a lever 2 which is rotatably mounted with its convex rotational surface relative to the force-transmitting element 4 and with its concave rotational surface relative to an eccentrically offset cylinder 11 by means of a respective bearing element 10, as a result of which an eccentric bearing structure is realized.
The cylinder or eccentric roller 11 has a horizontal through hole 12 for the rod 1. Vertical receptacles 13 for receiving pins 14 are provided in eccentric roller 11, perpendicularly and offset relative to cylinder axis Z and also perpendicularly transversely to throughbore 12.
In the installed state shown in fig. 4, the pin 14 passes through the vertical hole 15 shown in fig. 2 in the rod 1, whereby the entire brake actuating mechanism together with the eccentric support structure 11 is clamped as a preassembled unit on the rod 1 and thereby assembled together. The peg 14 and the hole 15 may for example form a press fit, which is dimensioned to be large enough that they do not separate automatically during operation of the disc brake.
According to the invention, this now makes it possible to fix the preloaded brake actuating mechanism in a simple manner in the rear side of the housing of the brake caliper, by screwing the eccentric roller 11 from the outside through the housing wall. For receiving correspondingly designed bolts, the eccentric roller 11 has in each case one receiving opening 16 on both sides of the rod 1 and on the same plane underneath it, for example as shown by the dashed lines in fig. 4.
According to the invention, the axis of the hole 16 or the axis of a bolt, not shown, is exactly aligned with the cylinder axis Z of the eccentric roller 11, i.e. the two axes intersect in one plane.
A second embodiment of a disc brake according to the invention is shown in fig. 5 to 10.
In this embodiment, the means for the loss-proof fixed connection of the eccentric support structure or eccentric roller 11 to the rod 1 are designed as a nut 20 which is accommodated in a correspondingly dimensioned receptacle or recess 21 in the eccentric roller 11.
As shown in particular in fig. 7 and 8, the nut 20 is screwed onto a thread 22 of the rod 1 provided at its rear end.
The nut 20 is in surface contact with a correspondingly shaped abutment surface 23 in the recess 21.
At the same time, the lever 1 has a circumferential shoulder 25 or the like, which is inserted complementarily in a recess or recess 24 in the eccentric roller 11 opposite the recess 21. The eccentric roller 11 is thus positioned exactly on the rod between the shoulder 25 and the nut 20.
As shown in fig. 9 and 10, according to the invention, the eccentric roller 11 is fixedly screwed to the housing 5 of the brake caliper on both sides of the rod 1 on the same plane aligned with respect to the cylinder axis Z of the eccentric roller 11 by means of a fastening device in the form of bolts 30, whereby the entire preassembled unit of the brake actuating mechanism is simultaneously positioned in the brake caliper in a functionally accurate manner. The eccentric roller 11 is in this case brought into contact with a corresponding semi-shell-shaped support surface 29 in the rear inner part of the housing 5.
As shown in particular in fig. 10, the invention brings the advantage that the rear part of the housing 5 of the brake caliper has only openings 28 for bolts 30 which are dimensioned relatively small, whereby the strength of the brake caliper is increased in this region 5.
