Abstract

A pad retaining spring for a brake pad on a disc brake includes a spring section which can be mounted captively and so that it can be radially deflected at an edge of the pad carrier plate. The lining retaining spring has a partial section designed as a clamping section which extends at an angle from one end of the spring section of the pad retaining spring. A brake pad retainer for a disc brake on a motor vehicle is also provided.

First claim

What is claimed is:

1 . A pad holding spring of a brake pad for a disc brake, comprising:
a spring section mountable in a manner secure against loss and allowing radial deflection on an edge of a pad carrier plate of the brake pad; and a spring subsection configured as a wedging section and extending at an angle from one end of the spring section.

2 . The pad holding spring according to claim 1 , wherein the subsection of the pad holding spring is of rectilinear design.

3 . The pad holding spring according to claim 1 , wherein the subsection of the pad holding spring is of at least partially undulating or serrated design transversely to the longitudinal extent of the subsection.

4 . The pad holding spring according to claim 2 , wherein the subsection of the pad holding spring is of at least partially undulating or serrated design transversely to the longitudinal extent of the subsection.

5 . The pad holding spring according to claim 3 , wherein a transitional subsection of the pad holding spring between the spring section and the subsection is of arc-shaped design.

6 . The pad holding spring according to claim 1 , wherein a transitional subsection of the pad holding spring between the spring section and the subsection is of arc-shaped design.

7 . The pad holding spring according to claim 5 , wherein the transitional subsection is formed in an arc such that the spring section and the subsection angled relative to the spring section enclose an angle (α) of 70° to 120°.

8 . The pad holding spring according to claim 6 , wherein the transitional subsection is formed in an arc such that the spring section and the subsection angled relative to the spring section enclose an angle (α) of 70° to 120°.

9 . The pad holding spring according to claim 1 , wherein the pad holding spring is designed as a leaf spring or as a wire spring.

10 . The pad holding spring according to claim 7 , wherein the pad holding spring is designed as a leaf spring or as a wire spring.

11 . A brake pad holding arrangement for a disc brake of a motor vehicle, wherein brake pads are associated on both sides with a brake disc, the arrangement comprising:
a fixed brake carrier having a pad slot with brake carrier horns which laterally enclose the brake pads, wherein each of the brake pads has at least one friction pad and one pad carrier plate carrying the friction pad and has at least one pad holding spring, which is secured against loss and held in a manner which allows radial deflection on an edge of the pad carrier plate facing away from a bridge of the brake carrier, wherein, in an installed state, the pad carrier plate of the brake pads is held positively on a brake carrier horn on a leading-edge side, and wherein, in a mounted position, a subsection of the pad holding spring extends over that edge of the pad carrier plate which faces the brake carrier horn on a trailing-edge side and into a gap between the brake carrier horn on the trailing-edge side and that lateral edge of the pad carrier plate which faces the brake carrier horn on the trailing-edge side.

12 . The brake pad holding arrangement according to claim 11 , wherein the subsection of the pad holding spring is matched to a contour of that lateral edge of the pad carrier plate which faces the brake carrier horn on the trailing-edge side.

13 . The brake pad holding arrangement according to claim 12 , wherein the subsection of the pad holding spring is of rectilinear design or is of at least partially undulating or serrated design transversely to a longitudinal extent of the subsection and to an axis of rotation of the brake pad.

14 . The brake pad holding arrangement according to claim 11 , wherein the subsection of the pad holding spring is of rectilinear design or is of at least partially undulating or serrated design transversely to a longitudinal extent of the subsection and to an axis of rotation of the brake pad.

15 . The brake pad holding arrangement according to claim 11 , wherein a transitional subsection of the pad holding spring between the spring piece arranged along that edge of the pad carrier plate which faces away from the bridge of the brake carrier and the subsection which extends into the gap between the brake carrier horn on the trailing-edge side and that lateral edge of the pad carrier plate which faces the brake carrier horn on the trailing-edge side is designed such that it runs in an arc around a corner region of the pad carrier plate.

16 . The brake pad holding arrangement according to claim 13 , wherein a transitional subsection of the pad holding spring between the spring piece arranged along that edge of the pad carrier plate which faces away from the bridge of the brake carrier and the subsection which extends into the gap between the brake carrier horn on the trailing-edge side and that lateral edge of the pad carrier plate which faces the brake carrier horn on the trailing-edge side is designed such that it runs in an arc around a corner region of the pad carrier plate.

17 . The brake pad holding arrangement according to claim 11 , wherein the pad holding spring is designed as a leaf spring or as a wire spring.

18 . The brake pad holding arrangement according to claim 16 , wherein the pad holding spring is designed as a leaf spring or as a wire spring.

19 . The brake pad holding arrangement according to claim 11 , wherein the arrangement is configured for a commercial vehicle disc brake.
