Description

technical field

[0001] The invention relates to a friction lining for industrial brakes and drive elements, said friction lining having a two-layer structure, wherein the friction layer is connected to a carrier layer, and to a method for producing a two-layer friction lining . Background technique

[0002] Friction linings in industrial brakes and industrial drive elements such as clutches are used to: hold static loads (holding brakes), brake rotational movements (dynamic brakes) or compensate relative movements (clutches). A two-layer friction material is known from DE 697 26 641 T2, which consists of a fibrous base material. The fibrous base material has a first layer and a second layer, said layers being joined to each other during the wet papermaking process. In this case, the first layer is formed from a friction material comprising fibers and / or filler material and / or friction particles. The second layer of friction material likewise includes fibers and / or filler ...

Embodiment Construction

[0022] exist figure 1 An exemplary embodiment of a friction lining 1 according to the invention is shown in FIG. 1 , which is designed to be annular. In side view it can be seen that the friction lining 1 is composed of two layers, namely the friction layer 2 and the carrier layer 3 , which can also be referred to as the base layer. The double-layer friction lining 1 is attached via a carrier layer 3 to a rigid rotor of an industrial brake or a drive element, for example a clutch, when used. The friction layer 2 is a plastic elastomer composition consisting of 0% to 25% elastomer in the form of rubber and 5% to 30% resin. The plastic elastomer composition has a filler content of between 45% and 70%.

[0023] The plastic elastomer composition forming the carrier layer 3 is a composite material consisting of SBR rubber with a proportion of between 10% and 40%. Additionally, between 0% and 20% resin and between 40% and 80% filler material are contained. In the produced state,...
