Abstract

The floating caliper of a disk brake has three bridge arms, which extend over the brake disk, wherein one of the bridge arms, preferably the middle arm (34), is bifurcated into two branches (34a, 34b).

Claims

1. Floating caliper for a disk brake, comprising two actuating cylinders and a brake shoe support lying opposite the actuating cylinders, wherein three bridge arms connect the actuating cylinders to the brake shoe support and wherein at least one bridge arm is bifurcated, wherein the bifurcated bridge arm is bifurcated in a direction towards the actuating cylinders into two branches and wherein each of the branches leads to one of the actuating cylinders.

2. Floating caliper for a disk brake according to claim 1, wherein the bifurcation lies at least approximately midway between the actuating cylinder and the brake shoe support.

3. Floating caliper for a disk brake according to claim 1, wherein the bridge arms are connected at the brake shoe support by a cross strut.

4. Floating caliper for a disk brake according to claim 1, wherein the bridge arms in their longitudinal direction are aligned in each case with a supporting finger of the brake shoe support, wherein the supporting fingers are disposed substantially at right angles to the longitudinal direction of the bridge arms.

5. Floating caliper for a disk brake according to claim 1, wherein the bridge arms extend separately from one another over substantially the entire distance between the actuating cylinders and the brake shoe support.

6. Floating caliper for a disk brake according to claim 1, wherein only the middle bridge arm is bifurcated and each of its branches leads to one of the two actuating cylinders.

7. Floating caliper for a disk brake according to claim 6, wherein the longitudinal axes of the branches of the middle bridge arm extend at angles of between 3°

and 15°

relative to an axial direction of the brake.

8. Floating-caliper disk brake having a floating caliper according to claim 1.
