Abstract
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.
Claims9
A coupling for an AWD vehicle, comprising a disc package with alternate discs, which are connected for rotation with, but are axially movable in relation to an ingoing and an outgoing axle, respectively, of the coupling, and
- a hydraulic piston for pressing the disc package together under the action of hydraulic pressure, hereby altering the coupling from a disconnect mode to a connect mode, in which the ingoing axle is connected to the outgoing axle,
- a coupling slack adjuster for mechanically establishing a rest position for the hydraulic piston in a disconnect mode, in which a predetermined slack in the disc package is established, irrespective of the wear of the discs.
