Abstract
In a housing (2) inner guide surfaces (3, 4, 5) and at least one first and one second stop (40, 41) fixed with respect to the housing are formed. A first and a second thrust plate (10, 11) are guided rotatably and axially displaceably at the guide surfaces (3, 4, 5) of the housing (2). Lugs (12, 13) on the thrust plates (10, 11) limit the rotation thereof in one direction of rotation by striking the first and second stop (40, 41). A first and a second set of brake discs (20, 24; 21, 25) are arranged adjacent the first and second thrust plate (10, 11). A first and a second intermediate disc (22, 23) are arranged between the brake discs (20, 24; 21, 25). Between the two thrust plates (10; 11), spreading members (46) are arranged which spread the thrust plates (10; 11) thereby initiating a braking with servo effect. Torque-transmitting connections between the thrust plates (10; 11) and the intermediate discs (22, 23) increase the servo effect. Each of the two intermediate discs (22, 23) comprises two projections (26, 28; 27, 29) which are arranged offset with respect to each other at equal angular intervals and are each associated with a projection (16, 18; 17, 19) of the associated thrust plate (10; 11) in such a manner that each intermediate disc (22, 23) can transmit to the associated thrust plate (10; 11) solely moments in the direction of rotation in which the lug (12; 13) of the respective thrust plate (10; 11) moves away from the associated stop (40; 41) fixed with respect to the housing.
