Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a brake lining mounting in a disk brake which is shown as a part detail, in a perspective view, and

(2) FIGS. 2 and 3 in each case show a part detail of the brake lining mounting, likewise shown in perspective.

DETAILED DESCRIPTION OF EMBODIMENTS

(3) FIG. 1 shows a disk brake for a commercial vehicle, with a brake caliper 1, in which two brake linings 3 which are assigned on both sides of a brake disk 2 are positioned.

(4) In each case spring-loaded by means of a lining holding spring 4, both brake linings 3 are held in a lining shaft of a stationary brake carrier (not shown) or in the brake caliper 1.

(5) Here, the respective lining holding spring 4 extends transversely with respect to the axial direction of the brake disk 2 and is fastened to the brake lining 3 such that it can be deflected radially.

(6) By means of a lining holder 5 which extends in the axial direction of the brake disk 2, spans a mounting opening of the brake caliper 1 and is supported on the lining holding springs 4, the latter are set under prestress, with the result that the brake linings 3 are pressed against the bottom of the lining shaft.

(7) According to the embodiment, the lining holder 5 consists of a cable, which may be a steel cable, with two cable sections 6 which run parallel to and at a spacing from one another and bear against the lining holding springs 4. The lining holder 5 is guided in the manner of a loop and is fastened by way of two free end regions 12 in a holder 8 which is of disk-shaped configuration.

(8) A screw 9 which is screwed into a threaded bore (not shown) of the brake caliper 1 is guided through the holder 8.

(9) The opposite end of the lining holder 5 which forms a U-shaped course is held in a groove 14 of a base 13 which is formed integrally on the brake caliper 1, the groove 14 which can be seen clearly in the enlarged illustration in FIG. 3 extending transversely with respect to the axial direction of the brake disk 2. That is to say transversely with respect to the cable sections 6, and being made in the base 13 on the side which faces away from the associated brake lining 3.

(10) That end region of the lining holder 5 which lies opposite the base 13 is depicted as a detail in another perspective in FIG. 2; it can be seen that, adjacently to a fastening element 7, a constituent part of which is the holder 8, a bump 10 is formed integrally on the brake caliper 1, and is expediently made during casting just like the base 13 if the brake caliper 1 consists of cast iron.

(11) On the upper side, the bump 10 has two notches 11 which are arranged at a spacing from one another, extend in the axial direction of the brake disk 2, and in which the cable sections 6 lie for guidance purposes.

(12) The end regions 12 run in an inclined manner toward the brake caliper 1 in comparison with the connected cable sections 6, to which end the fastening element 7 is lower than the notches 11.

(13) In order to tension the lining holder 5, in which the base 13 forms an abutment, an eccentric cam which cannot be seen since it lies on the concealed side is arranged on the holder 8, by way of which eccentric cam the cable sections 6 can be tensioned upon rotation, with the result that permanent prestress of the lining holding springs 4 is ensured.
