Problems solved by technology

In addition to the contact problem between the two dissimilar metals in these discs, the disc housing also needs to be manufactured separately and thus leads to higher costs
Furthermore, for friction rings made of cast steel, the problem of minimum wall thickness and the increased weight in this respect still exist

Embodiment Construction

[0024] figure 1 One half of a sectional view of an exemplary embodiment of a brake disc according to the invention is shown. The brake disc 1 includes a brake disc chamber 2 and a friction ring 3 . During braking, the friction ring 3 establishes contact with a brake pad (not shown), so that the rotation of the brake disc 1 is braked by the friction on the friction ring 3 . According to the invention, the brake disc chamber 2 and the friction ring 3 are designed in one piece from a flow-formed material. This has the substantial advantage that firstly the connection between the friction ring and the brake disk chamber has maximum strength. Secondly, thanks to the flow forming process or the flow spinning process, materials other than cast materials can be used for the manufacture of the brake disc, so that sufficiently low wall thicknesses can be achieved. Besides this, another advantage compared to other lightweight solutions is that due to the one-piece design of the brake ...

Abstract

The invention relates to a brake disc of a disc brake, comprising a brake disc chamber (2) and a friction ring (3), wherein the brake disc chamber and the friction ring of the brake disc are integral and formed by flow Constructed of heat or high temperature resistant grade steel.

Description

technical field [0001] The invention relates to a brake disc of a disc brake, which comprises a friction ring and a brake disc chamber. The invention also relates to a method for producing a brake disk and also to the use of said brake disk. Background technique [0002] Disc brakes are braking systems commonly used in motor vehicles, cranes or elevators. In these examples, disc brakes include brake pads that typically press against a rotating brake disc so that the rotational movement of the brake disc is braked. For this purpose, the brake disc comprises a brake disc chamber which has the shape of a cup and which has a friction ring fixed to the brake disc chamber. The pads of the disc brake are pressed against the surface of the friction ring. The brake disc chamber is used to fix the rotating shaft whose rotation is to be braked. Brake disc chambers and friction rings are usually manufactured from cast steel for mass production. Although very complex parts and brake...
