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.

Full plate disc brake, in particular for tractors

In a self-energizing disc brake of the spreading type the angular position of a pressure plate in a retracted 'brakes-off' position is determined by an adjuster member comprising a cam which cooperates with the plate and of which the relative position is adjustable. The cam is carried by a cam shaft which is radially or axially arranged, and is accessible from the exterior of the housing of the brake. The cam may be incorporated into and comprise the stop abutment for arresting angular movement of one of the plates when the brake is applied.

Self-energizing disc brakes

A self-energizing disc brake of the spreading type incorporates a drag-taking stop abutment for arresting angular movement of one of the pressure plates when the brake is applied. The stop abutment comprises a cam which is mounted on the inner end of a cam shaft, and the cam shaft is rotatable in a radial bore in the housing to adjust the relative circumferential position of the stop abutment.
