A clutch (2) with oil-lubricated discs (1, 5) makes use of a disc spring (11) as the closing spring (10), the force exerted by which in one working stroke drops at the spring travel increases. In a first part of the working stroke of the closing spring (10), from the fully closed to the open clutch (2) without clearance, the spring force of discs (1) taking the form of corrugated disc springs acts against that of the closing spring (10) in such a way that the sum of the spring forces remains substantially the same. A clutch (2) of the invention can be larger than previously customary because the pedal pressure, in normal or emergency situations, need generate only the sum of the spring forces which is small in relation to the strongest force of the closing spring (10) needed. |
