摘要： The invention relates to a friction layer for two opposing friction pieces which may be brought together and apart and which also circulate. At least one friction piece comprises a friction layer rigidly arranged on a support and a medium is found between the friction layer and the corresponding counterpiece to the friction piece. The material components for the material composition of the friction layer made from composite material, further additives and the binding composition of the above, are selected such that the material composition and hence the friction layer have considerable shrinkage properties caused by the heat treatment during the production thereof and shrinkage relative to the material of the support for the friction layer. As a result of the shrinkage process during the heat treatment, a network structure of irregularly distributed, directly interconnected channel-like recesses is embodied in the whole friction layer.

摘要： Disclosed is a synchronizer ring (10) comprising a support member (5), a conical frictional surface (9), and a frictional layer (14) that is applied to the frictional surface (9) and is made of a material containing carbon fibers. Said material represents a compressed, carbon fiber-reinforced plastic. The inventive synchronizer ring is inexpensive while being more resistant to wear than synchronizer rings known in prior art as a result of the improved dimensional stability of the frictional layer.

摘要： The invention relates to a method for producing a component of a synchronization device for manual transmissions, in particular a synchronizer ring (1, 2, 3), wherein a round blank produced from metal is formed in a plurality of forming steps. In order to simplify the production process, it is proposed according to the invention that at least one of the forming steps is a hot forming step in which the round blank is partially heated to a temperature of more than 600° C. and is then formed in the partially heated forming portion.
