Embodiment Construction

[0030] 1-12 show a brake disc 1 for a disc brake, which can be fastened on the hub of a commercial vehicle, in particular, with two concentric friction rings 2, which are formed for The friction surface of a not shown, compressible brake pad of the disc brake and is provided with a friction lining.

[0031] Furthermore, the brake disc 1 has a coaxial brake disc neck 3 into which a wheel axle of the motor vehicle can be inserted.

[0032] A connecting piece in the form of an annular spring element 4 is firmly connected in the region of the free end facing away from the friction ring 2 and is fastened to a hub or axle.

[0033] The elastic element 4 is axially elastically deformable relative to the friction ring 2 and has dimensions determined by the working stroke.

[0034] In addition, a spring element 4 arranged parallel to the friction ring 2 is preferably positively connected to the brake disk neck 3 . However, a force-fit or material-fit connection is also conceivable. ...

Abstract

Disclosed is a brake disk (1) for a disk brake, which can be fixed to a wheel hub, especially of a utility vehicle. Said brake disk (1) comprises two concentric friction rings (2) and a brake disk neck (3) that is connected thereto and is joined to the wheel hub. The inventive disk brake is embodied such that the brake disk neck (3) is fastened to the wheel hub by means of a joining piece which is connected in a fixed manner to said brake disk neck (3) and can be elastically deformed relative to the friction rings in an axial direction.

Description

technical field [0001] The invention relates to a brake disk according to claim 1 or the preamble to claim 13 which can be fastened to a wheel hub, in particular of a commercial vehicle. Background technique [0002] Such brake disks are used, for example, in so-called fixed-caliper disk brakes, wherein the brake disk is designed as a sliding disk which is mounted axially displaceably on a wheel hub or axle. [0003] During braking, the brake disc is pressed by a first brake pad against a second, opposite brake pad, wherein the corresponding contact surface of the brake disc is formed by the friction ring. [0004] In order to compensate the working travel caused by the air gap that the brake has to overcome during each braking operation and the elastic deformation of the brake lining and the brake caliper when the force is applied, a method is known from DE 101 48 681 A1 Brake disc, which is fastened to the hub or axle by means of an axially deflectable elastic connection....
