Engaging/disengaging device for transmission of piston force to partial clutch of dual clutch, has recesses present on circle diameters in housing part, and pistons assigned to clutches and arranged at radii that are identical or different

摘要

The device has a housing part (1.1) closed by another housing part (1.2) at an end side. Two recesses (A2) are present on two different pitch circle diameters in the former part. Pistons (2, 4) are inserted into the recesses and guided along inner walls of a housing. Sealing elements (9, 10) are assigned to the pistons. The pistons assigned to partial clutches are arranged at two radii, which are identical or different. The pistons are effectively connected with clutch release bearings (3, 5). An area (R2) acting as a pressure chamber is formed between one piston and one housing part.
