Abstract

A brake lining for a disc brake includes a distribution of lining elements which are arranged on a lining support or on group supports in groups, and the group supports are secured to the lining support. The lining elements have first lining elements and second lining elements, and the group supports have a first group support and a second group support. The first lining elements are arranged on the first group support or on the lining support in a non-tiltable and/or inflexible manner, and the second lining elements are arranged on the second group support or on the lining in a tiltable and/or flexible manner.

First claim

The invention claimed is:

1. A brake lining for a disk brake, the brake lining comprising:
a distribution of a plurality of lining elements arranged in groups on a lining support or on a group support of a plurality of group supports, wherein the group supports are attached to the lining support,
wherein the plurality of lining elements include one or more first lining elements and second lining elements,
wherein the first lining elements are arranged in a non-tiltable and/or inflexible fashion on a first group support and coupled to the lining support, and the second lining elements are arranged in a tiltable and/or flexible fashion on a second group support and coupled to the lining support.

2. The brake lining of claim 1 , wherein the first group support is attached to an end position of the lining support, wherein, of all the positions of the group supports on the lining support, the end position is a first position or last position on the lining support with respect to a relative movement between a brake disk or disk brake and the brake lining.

3. The brake lining of claim 2 , wherein the lining elements have at least a third lining element, wherein the group supports have a third group support, wherein the third lining elements are arranged in a non-tiltable fashion on the third group support, and the third group support is arranged at a further end position of the lining support which lies opposite the end position.

4. The brake lining of claim 3 , wherein the first, second and third group supports are part of the plurality of group supports, wherein at least one group support of which is attached in a non-tiltable fashion or tiltable fashion on the lining support.

5. The brake lining of claim 1 , wherein a gap is formed between the second lining elements and the second group support to permit tilting of the second lining elements.

6. The brake lining of claim 1 , wherein the first lining elements lie in a gap-free fashion on the first group support to prevent tilting.

7. The brake lining claim 1 , wherein all the lining elements of a group of lining elements are arranged in a non-tiltable or tiltable fashion on the respective group support.

8. The brake lining, of claim 1 , wherein the lining elements are arranged on the respective group supports in a rotatable fashion and/or the group supports are arranged in a rotatable fashion on the lining support.

9. The brake lining of claim 1 , wherein the lining elements are arranged in a rotationally fixed fashion on the respective group supports.

10. The brake lining of claim 9 , wherein the lining elements are polygons, wherein at least some of the lining elements adjoin one another with at least one of their side edges to prevent rotation.

11. The brake lining of claim 1 , wherein at least some of the lining elements are attached to the respective group supports by ball and socket joints, and/or at least some of the group supports are attached to the lining support by ball and socket joints, wherein the ball and socket joints permit rotation about a rotational axis and/or tilting with respect to the rotational axis, and wherein the rotational axis is perpendicular with respect to the distribution of the lining elements.

12. The brake lining of claim 1 , wherein the lining elements are pre-stressed elastically in relation to the respective group supports by springs.

13. The brake lining of claim 1 , wherein lining elements include attachment elements, which comprise a spherical-cap-shaped section to provide a spherical-joint-shaped connection to the respective group supports.

14. The brake lining of claim 1 , wherein the first lining elements have a different frictional material than the second lining elements.

15. A disk brake having a brake lining, wherein the brake lining has a distribution of a plurality of lining elements arranged in groups on a lining support or on a group support of a plurality of group supports, wherein the group supports-are attached to the lining support
wherein the plurality of lining elements include one or more first lining elements and second lining elements,
wherein the first lining elements are arranged in a non-tiltable and/or inflexible fashion on a first group support coupled to the lining support, and the second lining elements are arranged in a tiltable and/or flexible fashion on a second group support-coupled to the lining support.

16. A rail vehicle having a disk brake including a brake lining, wherein the brake lining has a distribution of a plurality of lining elements arranged in groups on a lining support or on a group support of a plurality of group supports, wherein the group supports are attached to the lining support,
wherein the plurality of lining elements include one or more first lining elements and second lining elements,
wherein the first lining elements are arranged in a non-tiltable and/or inflexible fashion on a first group support and coupled to the lining support, and the second lining elements are arranged in a tiltable and/or flexible fashion on a second group support and coupled to the lining support.

17. The rail vehicle of claim 16 , wherein the first group support is attached to an end position of the lining support, wherein, of all the positions of the group supports on the lining support, the end position is a first position or last position on the lining support with respect to a relative movement between a brake disk or disk brake and the brake lining.

18. The rail vehicle of claim 17 , wherein the lining elements have at least a third lining element, wherein the group supports have a third group support, wherein the third lining elements are arranged in a non-tiltable fashion on the third group support, and the third group support is arranged at a further end position of the lining support which lies opposite the end position.

19. The rail vehicle of claim 16 , wherein a gap is formed between the second lining elements and the second group support to permit tilting of the second lining elements.

20. The rail vehicle of claim 16 , wherein the first lining elements lie in a gap-free fashion on the first group support to prevent tilting.
