Abstract
The proposal is for a clutch arrangement consisting of at least one first clutch (4) and at least one second clutch (5). The first clutch (4) is arranged radially around the second clutch (5). Both clutches have balancing chambers (19, 20).
Claims5
A clutch arrangement having at least one first clutch and at least one second clutch (4, 5), each of the at least first and second clutches comprising:
- a first cylinder (6, 13) with at least one outer clutch disc (7, 14);
- a second cylinder (8, 15) with at least one an inner clutch disc (9, 16);
- a piston (10, 17) being coupled to apply an actuation force against the at least one outer clutch disc against the at least one inner clutch disc;
- a resetting member (12, 27) which, in an absence of an actuation force being applied by the piston (10, 17), returns the piston (10, 17) back to an initial retracted position;
- and a clutch balancing chamber (19, 20);
- wherein the first clutch (4) is radially disposed about the second clutch (5);
- the at least one second clutch has a disc (28) which together with the piston (17) forms the clutch balancing chamber (20) for the at least one second clutch (5);
- the piston (10) of the first clutch (4) and the first cylinder (13) of the second clutch (5) form the balancing chamber (19) for the at least one first clutch (4);
- and each of the balancing chambers counteracts changes in a pressure of the pistons as a result of rotation of the at least one first and the at least one second clutches (4, 5).
