Abstract
The invention relates to a vehicle brake, in particular a disc brake, and includes a backplate and a friction lining arranged on the front side of the backplate, wherein the backplate has a first radial support surface lying in a first radial plane for support against a first radial counter surface on a brake carrier or brake caliper. Furthermore, the backplate has a second radial support surface lying in a second radial plane for support against a second radial counter surface on a brake carrier or brake caliper. The first radial plane and the second radial plane are arranged to run at least largely parallel to one another, wherein the backplate has two tangential support surfaces lying in a common tangential plane for support against a tangential counter surface provided on a brake carrier or brake caliper.
Claims11
A brake pad for a vehicle brake, for a disc brake comprising a pad holder for the brake pad and a brake disc arranged about a brake center axis having a backplate and having a friction lining arranged on the backplate,
- wherein the backplate has a first radial support surface lying in a first radial plane for support against a first radial counter surface on the pad holder, wherein the backplate has a second radial support surface lying in a second radial plane for support against a second radial counter surface on the pad holder wherein the first radial plane and the second radial plane are arranged to run at least largely parallel to one another,
- wherein a brake pad center plane lying centrally between the first radial plane and the second radial plane runs through the brake center axis when the brake pad is inserted into the pad holder,
- and
- wherein the backplate has two tangential support surfaces lying in a common tangential plane for support against a tangential counter surface provided on a brake carrier or brake caliper,
- characterized in that
- the tangential plane forms an acute angle with the first radial plane and an obtuse angle with the second radial plane
A disc brake for vehicle axles, comprising
- at least one brake disc for arrangement on a wheel hub,
- a brake carrier which can be fixedly arranged on an axle body, wherein the brake disc, the wheel hub and the axle body are arranged about a brake center axis, and
- a brake caliper which can be arranged on the brake carrier and which overlaps the brake disc,
- wherein the brake carrier and/or the brake caliper have at least one pad holder, wherein the pad holder has a first radial counter surface lying in a first radial plane for support against a first radial support surface of a brake pad,
- wherein the pad holder has a second radial counter surface lying in a second radial plane for support against a second radial support surface of a brake pad in the pad holder,
- wherein the first radial plane and the second radial plane are arranged to run at least largely parallel to one another,
- wherein a brake center plane lying centrally between the first radial plane and the second radial plane runs through the brake center axis and, when a brake pad is inserted into the pad holder, a brake pad center plane is congruent with the brake center plane, and
- wherein the pad holder has at least one tangential support surface lying in a tangential plane for support against at least one tangential support surface provided on a brake pad, characterized in that the tangential plane forms an acute angle with the first radial plane and an obtuse angle with the second radial plane.
