Brake pad mounting for a disc brake for a commercial vehicle

Abstract

A brake pad mounting is provided for a disc brake for a commercial vehicle, having a pad mounting bracket which is supported on pad holding springs of brake pads which are arranged in a brake caliper on both sides of a brake disc. The pad mounting bracket spans a mounting opening of the brake caliper in the axial direction of the brake disc and is held in a fastening socket of the brake caliper at least on one side by way of a securing bolt, is configured in such a way that the securing bolt consists of two individual parts which are connected to one another in a positively locking and/or nonpositive and/or integrally joined manner and, on the end side, have in each case one head which can bear against an associated side surface of the pad mounting bracket.

Claims

1. A brake pad mount of a disc brake for a commercial vehicle, comprising: a pad mounting bracket supportable on pad mounting springs of brake pads arranged on both sides of a brake disc in a brake caliper of the disc brake, the pad mounting bracket bridging an assembly opening of the brake caliper in an axial direction of the brake disc and being held in a fastening socket of the caliper at least on one side via a securing bolt, wherein the securing bolt comprises two individual parts connected to one another in a positively locking, non-positively locking and/or integrally joined manner, on each end side of the securing bolt, a head is arranged that bears against an associated side face of the pad mounting bracket, wherein at an end lying opposite the head, the shank of the first individual part has a threaded shank whose diameter is less than a diameter of the shank, and the threaded shank is screwed into an internal thread of a shank of the second individual part, wherein the shanks of the first and second individual parts have identical diameters, and a spur toothing system is provided on end sides of the shanks which lay against one another, the spur toothing system having radially extending teeth which engage in a positively locking manner into one another in a screwed-in position.

2. The brake pad mounting according to claim 1, wherein the first individual part is adhesively bonded to the second individual part.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIGS. 1a) to 1c) show one exemplary embodiment of the invention in different views, and

(2) FIGS. 2a) and 2b) show a further exemplary embodiment of the invention in different views.

DETAILED DESCRIPTION OF THE DRAWINGS

(3) FIGS. 1a) and 1b) show part of a disc brake for a commercial vehicle, having a brake caliper 1, in which two brake pads can be positioned which are assigned on both sides of a brake disc and are not shown, however, just like the brake disc.

(4) Both brake pads are held in each case in a spring-loaded manner by way of a pad mounting spring in a pad shaft of a stationary brake carrier or in the brake caliper 1.

(5) Here, the respective pad mounting spring extends transversely with respect to the axial direction of the brake disc and is fastened to the brake pad such that it can be deflected radially.

(6) The pad mounting springs are set under prestress by way of a pad mounting bracket 3 which extends in the axial direction of the brake disc, bridges an assembly opening 2 of the brake caliper 1, and is supported on said pad mounting springs, with the result that the brake pads are pressed against the bottom of the pad shaft.

(7) The pad mounting bracket 3 is plugged with one end into a formed pocket 17 of the brake caliper 1, whereas the other end is held on an integrally formed fastening socket 5 of the brake caliper 1 by way of a securing bolt 7. The fastening socket 5 passes through a window cutout 4 of the pad mounting bracket 3.

(8) The securing bolt 7 is plugged in a transverse bore 6 of the fastening socket 5 and lies in a bead 18 of the pad mounting bracket 3 on the upper side which faces away from the brake caliper 1.

(9) The securing bolt 7 according to one design variant is shown as a detail in FIG. 1c), whereas FIG. 1a) shows the securing bolt 7 in an assembled perspective illustration, and FIG. 1b) shows it in a sectioned view.

(10) According to an embodiment of the invention, the securing bolt 7 consists of two individual parts 8, 9 which have an integrally formed head 10 at their respective one end, which head 10 bears against an associated side face 19 of the pad mounting bracket 3.

(11) As illustrated, in particular, by FIG. 1c), the first individual part 8 has a threaded shank 12 at its end which lies opposite the head 10, which threaded shank 12 is screwed into an internal thread 13 of the second individual part 9. Here, the diameter of the threaded shank 12 is smaller than that of a shank 11, onto which the threaded shank 12 is formed integrally and which carries the head 10 at its other end.

(12) As can be seen, both shanks 11 of the individual parts 8, 9 have the same diameter.

(13) The mutually facing end sides of the respective shank 11 are provided with a spur toothing system 14, the teeth of which run radially, and which spur toothing systems 14 engage into one another after the two individual parts 8, 9 are screwed to one another, with the result that an anti-rotation safeguard exists.

(14) FIGS. 2a) and 2b) show a further variant of the invention, in which the two individual parts 8, 9 consist of a pin 11 and an expanding sleeve 20 which, on the end side, in each case have a head 10 which bears against the associated side face 19 of the pad mounting bracket 3.

(15) As is illustrated very clearly, in particular, by FIG. 2b), the expanding sleeve 20 has a continuous slot 15 which makes radial expansion possible.

(16) To this end, in the non-assembled position, the inside diameter of the expanding sleeve 20 is slightly smaller than the shank 11 of the first individual part 8, a profiling 16, in the form of a plurality of circumferential grooves, being formed integrally on that end region of the shank 11 which lies opposite the head 10.

(17) In order to assemble the securing bolt 7, first of all the expanding sleeve 20 is plugged into the transverse bore 6. Afterward, the first individual part 8 is struck into the expanding sleeve 20, which is resisted by the latter, said expanding sleeve 20 expanding radially and being pressed against the reveal of the transverse bore 6.

(18) By way of the profiling 16, a positively locking connection is achieved with the inner wall of the expanding sleeve 20, by way of which positively locking connection the connection of both individual parts 8, 9 is secured.

(19) The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
