Problems solved by technology

This is of course only possible with considerable machining outlay, which is generally opposed to a reasonable machining of disc brakes
[0006] In addition, replacing a defective lining wear sensor is likewise only possible at considerable expense, especially with regard to the positioning of the lining wear sensor relative to the position of the brake lining or the reduction gear.
Replacing the lining wear sensor can therefore only be carried out by appropriately trained personnel, which is in contrast to the requirement for reduced operating costs

Embodiment Construction

[0024] exist figure 1 A disc brake, in particular for commercial vehicles, is shown in the figure, which comprises a brake caliper 1 which bridges a brake disc 24, each brake disc which is arranged on both sides of the brake disc 24 and contacts the brake disc during braking. Brake lining 25, a clamping device 23 and a readjustment device 2, by which the brake lining 25 on the clamping side can be pressed against the brake disc 24, wherein the two adjusting screws 3, 4 is transmitted to the brake lining 25 by the clamping device 23, and the wear-induced changes in the air gap between the brake lining 25 and the brake disc 24 can basically be compensated by said readjustment device. Variety. In this case, the readjustment device 2 is arranged on an adjusting screw 3 in a rotationally fixed manner.

[0025] In order to adjust the adjusting screws 3, 4 synchronously to compensate for the wear path, the two adjusting screws are coupled to each other via a chain drive, which cons...

Abstract

The invention relates to a disc brake for a utility vehicle, having a brake calliper which engages over a brake disc, having brake linings which make contact with the brake disc in the functional position, a brake application device with which one of the brake linings can be pressed, via at least one actuation spindle, against the brake disc, an adjustment device which is connected in a rotationally fixed fashion to the actuation spindle and with which wear-induced change in the running clearance between the brake lining and the brake disc can essentially be compensated, a closure lid which covers the adjustment device and is attached to the brake calliper, and a lining wear sensor which corresponds to a step-down gear mechanism which is connected to the actuation spindle, is embodied in such a way that a sensor which rotates on a concentric path and which corresponds to the lining wear sensor which is embodied as a contactless sensor and by means of which a change in the angular position of the sensor can be detected and transmitted to an evaluation device is connected to the step-down gear mechanism.

Description

technical field [0001] The invention relates to a disc brake, in particular for commercial vehicles, according to the preamble of claim 1 . Background technique [0002] In order to keep constant the air gap between the brake disc and the brake lining which exists in the non-operating position of the brake lining, also referred to as the working stroke, that is, to compensate for the The wear path caused by the abrasion of the friction lining of the disc brake, the known disc brake is equipped with a readjustment device at least on the clamping side. This is an adjusting screw that can move axially. [0003] A device is used for detecting brake lining wear, which consists of a reduction gear connected to one of the two adjusting screws and a lining wear sensor connected thereto. Such a device is known from DE 93 12 119 U1. [0004] It is proposed therein to use an angle of rotation sensor, which is designed as a rotary potentiometer, as the lining wear sensor. The state ...
