摘要： A coupling for an AWD vehicle comprises a disc package with alternate discs (6,7; 56, 57; 76, 77), which are connected for rotation with, but are axially movable in relation to an ingoing (1; 52, 71) and an outgoing axle (2; 51; 72), respectively, of the coupling, and a hydraulic piston (9; 59; 79) for pressing the disc package together under the action of hydraulic pressure, hereby establishing a connect mode, in which the ingoing axle is connected to the outgoing axle. A coupling slack adjuster (13-15; 64, 65; 83-85) is provided for mechanically establishing a rest position for the hydraulic piston (9; 59; 79) in a disconnect mode, in which a predetermined slack in the disc package is established, irrespective of the wear of the discs.

摘要： A disconnected, hydraulic disc coupling (4) in an AWD vehicle with a hydraulic cylinder (14) for its actuation is to be quickly connected or engaged. The effective piston area in the cylinder (14) is for that reason reduced during the connection phase.
