Embodiment Construction

[0033] exist figure 1 shows a disc brake for a commercial vehicle, which has, in its basic construction, a brake caliper 2 which encloses a brake disc 3 which is fastened in a non-rotatable on the axis shown.

[0034] The brake caliper 2 is arranged axially displaceable relative to the brake disc 3 on a stationary brake carrier 1 of the commercial vehicle.

[0035] Two fastening elements are provided, each having a guide rod 6 connected to the brake carrier 1 and fastened to the brake carrier 1 by means of screws not shown. In this case, one fastening element is designed as a fixed bearing 4 and the other fastening element is designed as a floating bearing 5 .

[0036] For supporting the guide rod 6 , that is to say for guiding the brake caliper 2 in the axial direction, the non-locating bearing 5 has a sliding bush 7 made of plastic, preferably elastomer, which according to the invention is held in a displacement-proof manner on the guide rod 6, as available in figure 2 ...

Abstract

A disc brake for a utility vehicle, having a brake calliper (2) which engages over a brake disc (3) and is held on a stationary brake carrier (1) such that it can be displaced axially in relation to the brake disc (3) by way of two fastening elements which are arranged in each case in a bore (9) of the brake calliper (2), are configured as plain bearings, and of which one is configured as a locating bearing (4) and the other is configured as a floating bearing (5), wherein the floating bearing (5) has a sliding bush (7) made from a plastic, in particular an elastomer, in which a guide rod (6) which is connected to the brake carrier (1) is mounted, is configured in such a way that the sliding bush (7) is held on the guide rod (6) such that it is secured against displacement and bears against the wall of the brake calliper-side bore (9), wherein the sliding bush (7) projects radially with respect to the guide rod (6).

Description

technical field [0001] The invention relates to a disc brake for a commercial vehicle according to the preamble of claim 1 . Background technique [0002] The brake caliper of a disk brake of the same type, also referred to as a sliding caliper, is held by means of a fastening element on a vehicle-side, ie stationary, brake carrier. [0003] For this purpose, the guide rod is fastened to the brake carrier, in particular by screws, which on the other hand are guided in the slide bearings of the brake caliper in such a way that the brake caliper is held in a rotationally fixed manner relative to the brake disc on the axle. It can move axially when braking. [0004] One of the sliding bearings is designed as a fixed bearing with a small sliding play and serves to guide the brake caliper axially in the main shaft, the bearing play being kept as small as possible. [0005] However, the other slide bearing, as a non-locating bearing, functionally has a larger bearing play, since...
