ABSTRACT:
The coupling device, such as a clutch, comprises an alternation of first discs (22) made from hardened steel and having teeth (25) for rotational coupling with a first member of the clutch, and second disc (19) having teeth (15) for rotational coupling with a second member of the clutch. The second discs (19) are made of carbon fibers embedded in a carbon base material, with no support inside the disc. The stable and progressive operation of the clutch and the life time of the discs are improved. Costs and space-requirement are reduced over all-carbon devices.
