Abstract

A disk brake, in particular for a vehicle, comprising a brake lining arrangement with a friction lining and a pad back plate. The friction lining can interact with a brake disk in order to achieve a braking effect. The disc brake also comprises a vibration damping device which is arranged on a brake caliper or on a brake support, comprising at least one additional mass which is designed as a separate component. The vibration damping device further comprises a receiving pin which is secured to the brake caliper or to the brake support and via which the additional mass can be fixed to the brake caliper or to the brake support.

First claim

1 . A disc brake for a vehicle comprising:
a brake pad assembly with a friction pad and a pad back plate, the friction pad being engageable with a brake disc in order to achieve a braking effect, and at least one vibration-damping device with at least one additional mass arranged on a brake caliper or on a brake carrier, wherein the additional mass is embodied as a separate component and the vibration-damping device further comprises a locating bolts fastened to the brake caliper or to the brake carrier by means of which the additional mass is configured to be fixed to the brake caliper or to the brake carrier, wherein the locating bolt is elongate and has on a lateral surface a groove structure aligned in its a longitudinal direction and/or transverse to the longitudinal direction, wherein the additional mass is configured to be fixed by pressing to the locating bolt such that the groove structure engages in a surface of the additional mass.

2 . The disc brake as set forth in claim 1 , wherein the locating bolts engage with a recess embodied in the additional mass.

3 . The disc brake as set forth in claim 1 , wherein a first thread is embodied on a part of the locating bolt facing toward the brake caliper or the brake carrier, the thread being securely connected to the brake caliper or the brake carrier by means of a second thread embodied on the brake caliper or on the brake carrier that is complementary to the first thread.

4 . The disc brake as set forth in claim 1 , wherein the locating bolt and/or the additional mass is substantially cylindrical.

5 . The disc brake as set forth in claim 1 , wherein an annular groove is embodied in the locating bolt at an end facing away from the brake caliper or the brake carrier in which a circlip engages around the locating bolt such that the circlip prevents the additional mass from detaching from the locating bolt.

6 . A disc brake for a vehicle comprising:
a brake pad assembly with a friction pad and a pad back plate, the friction pad being engageable with a brake disc in order to achieve a braking effect, and at least one vibration-damping device with at least one additional mass arranged on a brake caliper or on a brake carrier, wherein the additional mass is embodied as a separate component and the vibration-damping device further comprises a locating bolt fastened to the brake caliper or to the brake carrier by means of which the additional mass is configured to be fixed to the brake caliper or to the brake carrier, wherein the additional mass has a base portion in the form of a flat fastening tab and a block portion, the block portion having a greater mass than the base portion and the fastening tab lying flat against the brake caliper or the brake carrier.

7 . The disc brake as set forth in claim 6 , wherein the locating bolt engages with a recess embodied in the additional mass, the recess being embodied as a core hole bore in the additional mass in the region of the base portion.

8 . The disc brake as set forth in claim 1 , wherein a plurality of additional masses are configured to be fixed at different receiving points to the brake caliper or to the brake carrier by means of substantially equivalent locating bolts, wherein at least two of the additional masses are arranged on opposite sides of the brake caliper or brake carrier with respect to the brake disc.

9 . The disc brake as set forth in claim 8 , wherein at least two of the additional masses have different masses and/or the block portions are aligned differently with respect to the base portions.

10 . The disc brake as set forth in claim 6 , wherein a respective groove structure is embodied on the base portion or base portions that engages in a surface of the brake caliper or of the brake carrier.

11 . The disc brake as set forth in claim 8 , wherein at least two of the additional masses are configured to be fixed by means of the same locating bolt at the same receiving point to the brake caliper or to the brake carrier.

12 . The disc brake as set forth in claim 8 , wherein the additional mass is made of a material having a greater density and/or elasticity than the material of which the brake caliper or brake carrier is made in the vicinity of the respective receiving point.

13 . The disc brake as set forth in claim 1 , wherein the disc brake is embodied as a fixed-caliper disc brake, wherein the brake caliper engages around the brake disc and the vibration-damping device is arranged on the brake caliper.

14 . The disc brake as set forth in claim 1 , wherein the disc brake is embodied as a floating-caliper disc brake, wherein the brake caliper engages around the brake disc and is displaceably mounted on the brake carrier.

15 . The disc brake as set forth in claim 14 , wherein the locating bolt is a guide screw of a guide mechanism of the brake caliper that is extended beyond a surface of the brake caliper.

16 . A kit comprising a disc brake as set forth in claim 1 , wherein commensurately dimensioned additional masses are configured to optionally be put in place according to different vibration frequencies to be dampened by the vibration-damping device.

17 . The disc brake as set forth in claim 6 , wherein the disc brake is embodied as a fixed-caliper disc brake, wherein the brake caliper engages around the brake disc and the vibration-damping device is arranged on the brake caliper.

18 . The disc brake as set forth in claim 6 , wherein the disc brake is embodied as a floating-caliper disc brake, wherein the brake caliper engages around the brake disc and is displaceably mounted on the brake carrier.

19 . A kit comprising a disc brake as set forth in claim 6 , wherein commensurately dimensioned additional masses are configured to optionally be put in place according to different vibration frequencies to be dampened by the vibration-damping device.
