Disk Brake

Abstract

The present invention relates to a disk brake in which a connection is configured between a brake lining retainer and a pressure plate of a push rod in order to move the push rod by means of the brake lining retainer so that it slides axially in a brake caliper

Claims

1. A disk brake consisting of a brake caliper that overlaps at least one brake disk and a brake actuation mechanism that is enclosed in the brake caliper and includes a reinforcing mechanism to convey braking force into a push rod, which is positioned so that it can slide in the brake caliper and has on its brake disk end a pressure plate in order to transmit the braking force by a brake lining retainer and a brake lining to the brake disk, and where the brake lining retainer is moved radially and tangentially with the brake lining in the brake caliper or in a carrier that guides the brake caliper, characterized in that the pressure plate is connected with the brake lining retainer in such a way that during brake actuation and brake force release the push rod is moved axially by the brake lining retainer in the brake caliper.

2. A disk brake according to claim 1, wherein the pressure plate on its side facing the brake disk has at least one connecting element, which acts with a form-complementary connecting element, which is positioned on its side facing the brake disk on the brake lining retainer.

3. A disk brake according to claim 2, wherein the pressure plate has two projections at a distance to one another, which engage into two corresponding form-complementary recesses in the brake lining retainer.

4. A disk brake according to claim 2, wherein the pressure plate has two recesses at a distance to one another, into which two corresponding, form-complementary projections of the brake lining retainer engage.

5. A disk brake according to claim 2, wherein the brake lining retainer has a recess, which receives the pressure plate completely, in form complementary manner.

6. A disk brake according to claim 2, wherein the brake lining retainer has two projections opposite one another, which receive the pressure plate, surrounding its sides.

7. A disk brake according to claim 3, wherein between the connecting elements there is, in each case, a clearance with sufficient tolerance so that the pressure plate is fixed radially and tangentially and at the same time replacement of the brake lining retainer is ensured whenever necessary.

8. A disk brake according to claim 1, wherein at least one spring clamp is provided, which extends over the brake lining retainer and the pressure plate, holding them firmly connected to one another.

9. A disk brake according to claim 1, wherein the push rod is configured as a traverse having two parallel adjustment spindles mounted so that they can rotate on it, and the pressure plate interacts with the two adjustment spindles.

10. A disk brake according to claim 1, wherein the push rod is configured as an essentially rotation-symmetric cam with an adjustment spindle mounted on it, and the pressure plate interacts with the adjustment spindle.

11. A disk brake according to claim 9, where in the push rod is moved in the brake caliper in the area of its end that faces the brake disk and on which the reinforcing mechanism is applied.

12. A disk brake according to claim 11, wherein the push rod is moved in the brake caliper on four diagonally opposite slide surfaces.

13. A brake lining retainer for a brake lining for a disk brake, which can be moved radially and tangentially in a brake caliper or in a carrier, which guides the brake caliper, characterized in that devices are provided on the side opposite the brake linings for connecting with a pressure plate of a push rod of a brake actuation mechanism of the disk brake.

14. A brake lining retainer according to claim 13, wherein two recesses are provided at a distance to one another, into which two form-complementary projections of the pressure plate can be received.

15. A brake lining retainer according to claim 13, wherein to projections are provided at a distance to one another, which can be received in two corresponding, form-complementary recesses of the pressure plate.

16. A brake lining retainer according to claim 13, wherein two projections are provided opposite to one another, between which the pressure plate can be received by embracing its sides.
