Embodiment Construction

[0033] according to figure 1 The coil spring 1 has a coil spring first end 2, a coil spring second end 3 and is arranged between the coil spring first end 2 and the coil spring second end 3 The coiled spring section 4. The wrap-around spring section 4 is divided into two wrap-around spring turns 6 , 6 a. The first end 2 of the wrap spring extends over 90 degrees in the circumferential direction. Thus, the switching angle of the readjustment device 10 (not shown) can be halved compared to the prior art. The first coil 6 of the wrap spring has a U-shaped projection 7 . The introduction of a load L on the U-shaped projection 7 leads to a bending moment on the U-shaped projection 7 which deforms slightly under load. As a result, a radial force is formed on the side of the U-shaped projection 7 opposite the load introduction L which prevents further deformation and limits bending on the side of the load introduction L moment.

Abstract

The invention relates to a wrap spring for blocking an undesired rotational movement of a rotary element. Furthermore, the invention relates to a readjustment device for readjusting the wear of brake linings of a disc brake. The readjustment device comprises: a guide sleeve in which a coiled spring is arranged; a grooved ring surrounding the guide sleeve, wherein the grooved ring is coupled to the closure cap via a torsion spring; and a surrounding belt A split ring for a grooved ring. Furthermore, the invention relates to a disc brake for a vehicle, in particular for a commercial vehicle, wherein the disc brake is provided with a readjustment device with a coil spring.

Description

technical field [0001] The invention relates to a wrap spring for blocking an undesired rotational movement of a rotary element. The invention also relates to a readjustment device for readjusting the wear of brake linings of a disc brake. The readjustment device comprises: a guide sleeve, in which a coiled spring is arranged; a grooved ring surrounding the guide sleeve, wherein the grooved ring is coupled to the closure cap via a torsion spring; and an open ring surrounding the grooved ring pieces. Furthermore, the invention relates to a disc brake for a vehicle, in particular for a commercial vehicle, wherein the disc brake is provided with a readjustment device with a coil spring. Background technique [0002] Compression devices with readjustment devices for readjusting the air gap between brake lining and brake disc are known. In general, such disc brakes can usually be actuated pneumatically or electromechanically. [0003] For example, in the field of commercial v...
