Abstract

A brake pad arrangement for a vehicle brake, having a frictional pad, a pad back plate and a damping plate that is arranged on the pad back plate, the brake pad arrangement having a separate damping element which is provided in order to avoid frictional vibrations of the brake pad arrangement.

First claim

The invention claimed is:

1. A brake pad arrangement for a vehicle brake having
a friction pad,
a pad back plate having an extension which is adapted to guide the brake pad arrangement in the vehicle brake, and
a damping plate which is arranged on the pad back plate,

wherein the brake pad arrangement comprises a separate damping element, which is adapted to damp frictional vibrations of the brake pad arrangement, and the damping element has at least one fixing element which acts on a front side, rear side and/or laterally on the pad back plate, in order to fix the damping element on the pad back plate, the fixing element comprising at least one latching element which is engageable with a correspondingly shaped indentation in the pad back plate, and the damping element being of u-shaped configuration and the damping element being arranged on the pad back plate in such a manner that limbs of the damping element engage around the pad back plate laterally below the extension,
wherein the fixing element has an aperture or engaging limb which is engageable with a positioning projection arranged on the pad back plate, in order to fix and position the damping element on the pad back plate.

2. The brake pad arrangement according to claim 1 ,
wherein the damping element is connected to the pad back plate in such a manner that at least a part of the damping element bears in a manner free from play against the pad back plate.

3. The brake pad arrangement according to claim 1 ,
wherein the damping element is connected to or with the pad back plate via a latching connection, an adhesive-bonding connection and/or with the aid of a biasing force.

4. The brake pad arrangement according to claim 1 ,
wherein the fixing element has a clamping force which is produced owing to elastic deformation of the fixing element and can be exerted on the damping element, in order to fix the damping element on the pad back plate.

5. The brake pad arrangement according to claim 1 ,
wherein the damping element is biased in a state attached to the pad back plate, the damping element being received under vibration-reducing biasing on installation in a brake carrier.

6. The brake pad arrangement according to claim 1 ,
wherein the damping element has a portion or arm which is situated on a side facing the friction pad and is formed in such a manner that, when a wear limit of the friction pad is reached, a striking of a brake disc of the vehicle brake on which the friction pad can act is initiated, thereby resulting in a warning noise indicating a worn friction pad.

7. The brake pad arrangement according to claim 1 ,
wherein damping material is arranged between the damping element and the pad back plate at the contact surface.

8. The brake pad arrangement according to claim 7 ,
wherein the damping material is an adhesive layer.

9. The brake pad arrangement according to claim 1 ,
wherein the damping element is of one part and is produced from bent sheet metal or plastic.

10. A disc brake arrangement for a vehicle system having a brake disc and the brake pad arrangement according to claim 1 , the brake pad arrangement being arranged so as to be movable relative to the brake disc in order to act on the brake disc by means of the friction pad.

11. The brake pad arrangement according to claim 1 ,
wherein the limbs of the damping element engage around the pad back plate vertically below the extension.

12. The brake pad arrangement according to claim 1 ,
wherein the damping element comprises engaging limbs disposed adjacent the pad back plate.

13. A brake pad arrangement for a vehicle brake having
a friction pad,
a pad back plate having an extension which is adapted to guide the brake pad arrangement in the vehicle brake, and
a damping plate which is arranged on the pad back plate,

wherein the brake pad arrangement comprises a separate damping element, which is adapted to damp frictional vibrations of the brake pad arrangement, and the damping element has at least one fixing element which acts on a front side, rear side and/or laterally on the pad back plate, in order to fix the damping element on the pad back plate, the fixing element comprising at least one latching element which is engageable with a correspondingly shaped indentation in the pad back plate, and the damping element being of u-shaped configuration and the damping element being arranged on the pad back plate in such a manner that limbs of the damping element engage around the pad back plate laterally below the extension,
wherein the entire damping element engages around the pad back plate vertically below the extension.

14. A brake pad arrangement for a vehicle brake having
a friction pad,
a pad back plate having an extension which is adapted to guide the brake pad arrangement in the vehicle brake, and
a damping plate which is arranged on the pad back plate,

wherein the brake pad arrangement comprises a separate damping element, which is adapted to damp frictional vibrations of the brake pad arrangement, and the damping element has at least one fixing element which acts on a front side, rear side and/or laterally on the pad back plate, in order to fix the damping element on the pad back plate, the fixing element comprising at least one latching element which is engageable with a correspondingly shaped indentation in the pad back plate, and the damping element being of u-shaped configuration and the damping element being arranged on the pad back plate in such a manner that limbs of the damping element engage around the pad back plate laterally below the extension,
wherein the extension is a first extension, and the pad back plate has a second extension opposite the first extension and which is also adapted to guide the brake pad arrangement, and, in a direction from the second extension to the first extension, the first extension extends further than the damping element.
