Abstract
A wet multi-disk clutch comprises an input member (2) and an output member (3), and first disks (22) and second disks (21), which are connected to the input member (2) and the output member (3) respectively and can be pressed together by actuating means (24). In order to create a low-vibration tribosystem with a long life, the first disks (22) are composed of steel and their friction faces are linings (42) composed of carbon fibers embedded in a carbon matrix and having channels (43) leading from the inside outward, and the second disks (21) are composed of steel and their friction faces are provided with a nickel dispersion layer.

A wet multi-disk clutch in part of a vehicle drive and a lubricant for a housing containing said clutch, comprising an input member (2) and an output member (3), and a number of first disks (22) and second disks (21), which are connected to the input member (2) and the output member (3) respectively and can be pressed together by actuating means (24), wherein
- a) the first disks (22) are composed of steel and their friction faces are linings (42) composed of carbon fibers embedded in a carbon matrix, which are interrupted by channels (43) leading from the inside outward, and
- b) the second disks (21) are composed of steel and their friction faces are provided with a nickel dispersion layer.
A coupling that senses a differential rotational speed between an input member and an output member comprises a wet multi-disk clutch having a number of first disks (22) and second disks (21), which are connected to the input member (2) and the output member (3) respectively and can be pressed together by actuating means (24), wherein a) the first disks (22) are composed of steel and their friction faces are linings (42) composed of carbon fibers embedded in a carbon matrix, which are interrupted by channels (43) leading from the inside outward, and b) the second disks (21) are composed of steel and their friction faces are provided with a nickel dispersion layer.
