Cover plate for a disc brake

Abstract

A cover panel (1) for a disc brake (2) for covering an installation opening (5) of the disc brake (2), wherein the disc brake (2) comprises a brake carrier (13) and a brake caliper (3) sliding on the brake carrier (13) axially in the direction of an application side (Z) or axially in the direction of a rim side (F).

Claims

1. A disc brake (2) comprising: a brake carrier (13); a brake caliper (3) sliding on the brake carrier (13) axially toward an application side (Z) or axially toward a rim side (F); an installation opening (5) defined in the brake caliper (3) for removing and for fitting brake pads; and a cover panel (1); wherein the cover panel (1) includes a cable guide (6) for fixing a cable (7); wherein the cover panel (1) extends substantially across an axial width and a circumferential length of the installation opening and substantially covers the installation opening, wherein the cover panel extends across substantially the entire installation opening; wherein the cover panel includes a plurality of spaced apart fixing elements along the cable guide for securing a cable in the cable guide, wherein cable guide, cover panel, and the fixing elements are monolithically formed as a one-piece homogenous structure.

2. The disc brake (2) of claim 1, wherein the cover panel extends fully across the circumferential length of the installation opening.

3. The disc brake (2) of claim 1, wherein a circumferential length of the cover panel is greater than an axial width of the cover panel.

4. The disc brake (2) of claim 1, wherein the cover panel defines a curvature corresponding to a curvature of the brake caliper (13) such that the brake caliper and the cover panel combine to define a generally continuous curvature.

DETAILED DESCRIPTION OF THE DRAWINGS

(7) FIG. 1 shows a disc brake 2 with a cover panel 1 according to the invention. A cable guide 6 is integrated in the cover panel 1. The cover panel 1 covers an installation opening 5 of a brake caliper 3 for removing and for fitting brake pads 12, 12a. The brake pads 12, 12a are illustrated in FIG. 4. The brake caliper 3 is arranged on a brake carrier 13, wherein the brake caliper 3 is mounted on the brake carrier 13 so as to be displaceable axially along the disc brake axis A. Furthermore, the cover panel 1 is arranged on the brake caliper 3 radially with respect to a disc brake axis A. In order to fix the cover panel 1 on the disc brake 2, the cover panel 1 has what are referred to as retaining struts 9, 9a, 9b, 9c. The retaining struts 9, 9a, 9b, 9c and the cable guide 6 are formed from the cover panel 1 by means of forming and punching. The retaining struts 9, 9a, 9b, 9c run coaxially along the disc brake axis A. A pad retaining clamp 4 secures the brake pads 12, 12a against dropping radially out of a brake pad carrier well 16, 16a (see FIG. 4) of the brake carrier 13. The retaining struts 9, 9a, 9b, 9c span the pad retaining clamp 4. Two screws 10, 10a additionally secure the cover panel 1 against moving radially with respect to the disc brake axis A. The screw 10 is connected to the pad retaining clamp 4 via a bore 15 in the retaining strut 9a. The second screw 10a is connected to the pad retaining clamp 4 via a bore 15a in the retaining strut 9c. The bore 15 of the retaining strut 9a and the bore 15a of the retaining strut 9c are illustrated in FIG. 3. Between the retaining struts 9, 9a, 9b, 9c, a fixing element 8 is arranged as cable guide 6 on the cover panel 1 and two further fixing elements 8a, 8b are arranged on the retaining struts 9a, 9b. Supporting elements 17, 17a of the cover panel 1 engage under the pad retaining clamp 4 and secure the cover panel 1 in the radial direction opposite the brake disc. The cover panel 1 is supported in the tangential direction on the pad retaining clamp 4 by means of securing elements 18, 18a, 18b, 18c, 18d, 18e.

(8) FIG. 2 shows the disc brake 2 according to FIG. 1 in top view. In FIG. 2, a cable 7 is additionally arranged in the cable guide 6 of the cover panel 1. The cable 7 is a pad wear sensor cable and is arranged in the cable guide 6 axially along the disc brake axis A, from an application side Z of the disc brake 2 in the direction of a rim side F of the disc brake 2. The cable 7 is clamped in the manner of a labyrinth between the fixing elements 8, 8a, 8b.

(9) FIG. 3 shows the cover panel according to FIG. 1 and FIG. 2 in detail. In particular, the bore 15 in the retaining strut 9a for fixing the screw 10 and the bore 15a in the retaining strut 9c for fixing the screw 10a are visible. In particular, the arrangement of the securing elements 18, 18a, 18b, 18c, 18d, 18e and the arrangement of the supporting elements 17, 17a can be seen.

(10) FIG. 4 shows the disc brake 1 in a laterally sectioned view. FIG. 4 once again illustrates the covering of the installation opening 5 by the cover panel 1, as a result of which the brake pads 12, 12a and the brake disc, which is arranged between the brake pads 12, 12a but is not shown, are protected against environmental influences, such as dust or snow.

(11) While the above description constitutes the preferred example of the present invention, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope and fair meaning of the accompanying claims.
