Embodiment Construction

[0033] The exemplary embodiment of the disc brake according to the invention shown in the figures has a (not shown) brake disc, the axis of rotation of which is designated A. The direction of rotation when driving forward is marked with arrow D. The brake has a brake caliper 20 and a brake carrier 22 , wherein the brake caliper surrounds a (not shown) brake disk in a frame-like manner. The brake pad on the rim side, which is formed from a metal backing plate with friction lining, is designated with the reference numeral 24 , while the brake pad on the application side, which is formed from a metal backing plate with friction lining, is designated with the reference numeral 26 Note, the pressure plate is marked with reference numeral 28 . The elements mentioned are force transmission elements. The force transmission elements are compressed, ie prestressed in the radial direction, by the compression springs 30 , 32 or 34 . As will be explained later, the brake pads 26 and the...

Abstract

A caliper disc brake of a vehicle, in particular of a commercial vehicle, with a brake disc having an axis of rotation, a brake caliper, a brake anchor plate, a force transmission element, such as, for example, a lining support and / or a pressure plate, which is guided and supported in a shaft of the brake caliper or of the brake anchor plate, a holding-down spring (32) for holding down the force transmission element, and a holding-down device (36) which is held and supported on the caliper by a holding device, pretensions the holding-down spring radially against the force transmission device and pretensions the holding-down spring tangentially in the direction of rotation against the force transmission device during forwards travel, wherein the holding device has a centre line lying parallel to the axis of rotation. The holding-down spring has two identical spring legs and a trapezoidal central region which is located in between and projects radially inwards, wherein the two legs of the trapezoidal region each enclose an angle of more than 95 degrees with the base in the relaxed state and an angle of less than 85 degrees with the respectively adjacent spring leg.

Description

technical field [0001] The invention relates to a caliper disc brake for a vehicle, in particular a commercial vehicle, with a brake disc having an axis of rotation, a brake caliper, a brake carrier, a force transmission element such as a friction plate carrier and / or a pressure plate , the force transmission element extends and is supported in the cavity (Schacht) of the brake caliper or brake bracket, and the caliper disc brake also has a compression spring for compressing the force transmission element and is held and supported on the caliper by a holding device The compression device prestresses the compression spring radially against the force transmission device and pretensions the compression spring tangentially in the direction of rotation during forward travel against the force transmission device, wherein The holding device has a centerline parallel to the axis of rotation. Background technique [0002] A brake of the type mentioned at the outset is known, for exa...
