Caliper disk brake of a vehicle
A caliper disk brake of a vehicle with a brake disk, a brake caliper, a brake anchor plate, a force transmission element guided and supported in a shaft of the brake caliper or of the brake anchor plate, a holding-down spring for holding down the force transmission element, and a holding-down device held and supported on the caliper by a holding device, pretensions the holding-down spring radially against the force transmission device and pretensions the holding-down spring tangentially in the direction of rotation against the force transmission device during forwards travel. The holding device has a center line parallel to the axis of rotation of the brake disk. The tangential pre-tensioning is at least partially attributed to the dimensions of the holding-down device, as measured in the tangential direction from the center line, being larger at least in sections on the disk exit side than on the disk entry side.
1. A caliper disk brake of a vehicle, comprising:
a brake disk having an axis of rotation;
a brake caliper;
a back plate assembly;
a force transmission element guided and supported in a channel of the brake caliper or the back plate assembly;
a hold-down spring configured to hold down the at least one force transmission elements;
a hold-down yoke configured to pre-stress the hold-down spring radially against the force transmission element and to pre-stress the hold-down spring against the force transmission element tangentially in a direction of rotation during forward travel of the vehicle; and
a holding device configured to hold and support the hold-down yoke on the brake caliper, the holding device having a centerline parallel to the axis of rotation of the brake disk,
wherein a width of the hold-down yoke in the direction of rotation from a first point on a radial plane to an edge of the hold down yoke on a disk run-out side of the brake disk, the radial plane extending through the centerline and the axis of rotation of the brake disk, is greater than a width of the hold-down yoke in the direction of rotation from an edge of the hold down yoke on a disk run-in side of the brake disk to the first point on the radial plane.
2. The caliper brake as claimed in claim 1 , wherein the holding device is symmetrical in relation to the radial plane containing the centerline.
3. The caliper disk brake as claimed in claim 2 , wherein the holding device comprises a projection extending in a direction of the axis of rotation, lateral flanks of the projection being configured to absorb tangential forces and a radially inner flank of the projection being configured to absorb radial forces.
4. The caliper disk brake as claimed in claim 3 , wherein the projection has a roof edge-like shape.
5. The caliper disk brake as claimed in claim 3 , wherein the projection is disposed on an actuation side of the holding device.
6. The caliper disk brake as claimed in claim 2 , wherein the holding device comprises a coding device.
7. The caliper disk brake as claimed in claim 6 , wherein the coding device comprises a shoulder.
8. The caliper disk brake as claimed in claim 2 , wherein the holding device comprises a threaded connection.
9. The caliper disk brake as claimed in claim 2 , wherein the coding device and/or the threaded connection is/are disposed on a wheel rim-side of the holding device.
10. The caliper disk brake as claimed in claim 1 , wherein the brake caliper is a sliding caliper.
11. The caliper disk brake as claimed in claim 1 , wherein the at least one force transmission element is a brake-pad plate and/or a pressure plate.
12. The caliper disk brake as claimed in claim 1 , wherein the brake caliper is formed by casting.
13. The caliper disk brake as claimed in claim 1 , wherein the hold-down yoke comprises tangential shoulders on an actuation side but not on a wheel-rim side.
14. The caliper disk brake as claimed in claim 13 , wherein the first point on the radial plane is located in the direction of rotation from an edge of a tangential shoulder of the hold-down yoke on the disk run-in side of the brake disk and in a direction opposite the direction of rotation from an edge of a tangential shoulder of the hold-down yoke on the disk run-out side of the brake disk.
15. The caliper disk brake as claimed in claim 14 , wherein the first point on the radial plane is located at the actuation side of the hold-down yoke.
16. The caliper brake disk as claimed in claim 3 , wherein the first point on the radial plane is located in the direction of rotation from a lateral flank of the projection on the disk run-in side of the brake disk and in a direction opposite the direction of rotation from a lateral flank of the projection on the disk run-out side of the brake disk.
17. The caliper disk brake as claim in claim 1 , wherein the first point on the radial plane is located in a direction of an actuation side of the hold down yoke from a wheel-rim side of an actuation side brake lining.
