Abstract:
A coupling device with two parts which are coaxially rotatable relative to one another, comprising a friction coupling whose friction plates are alternately connected to each of the rotatable parts. Further the coupling device comprises an actuating device for the friction coupling, which comprises an annular chamber formed in one of the rotatable parts and containing a highly viscous fluid. A rotational chamber is arranged in the annular chamber and is drivingly connected to the other one of the rotatable parts. The actuating device, when the rotatable parts rotate relative to one another, causes an increase in pressure for the purpose of loading the friction coupling.

Two axle shaft gears are rotatably held in cylindrical bores in the differential carrier and are arranged coaxially relative to one another. A plurality of differential gears are supported in an axis-less way in bores in the differential carrier and are arranged so as to be axis-parallel. One group of the differential gears engages the one of the axle shaft gears and the other group engages the other of the axle shaft gears. At least one of the group of the differential gears engages the respective other group of the differential gears. At least the tooth heads of the differential gears are provided with grooves, with at least the bores or pockets for the differential gears in the differential carrier being provided with grooves.
Abstract:
A drive assembly for the driveline of a motor vehicle with an axle which can be driven when required. The drive assembly includes a drive and a multi-plate coupling. The drive comprises a drive housing with a sleeve-shaped projection in which a drive input shaft is rotatably supported. The multi-plate coupling which is rotatably supported in a coupling housing connected to the drive housing comprises a coupling input part for introducing torque and a coupling output part connected to the drive input shaft in a rotationally fast way. The multi-plate coupling is arranged coaxially on the outside relative to the sleeve-shaped projection and partially axially covers the latter.
Abstract:
A differential carrier is disclosed containing sideshaft gears supported in the carrier so as to be coaxially rotatable around a longitudinal axis (A). Differential gears are supported in the carrier on axes of rotation (R) positioned radially relative to the longitudinal axis (A) and have teeth engaging those of the sideshaft gears, and a multi-plate coupling in the carrier to extend coaxially relative to the axis. The carrier includes a flange to which a ring gear can be bolted, and is formed of a dish-shaped part with a base and an integrally formed-on flange and a cover which is axially fixed by an annular securing element. The multi-plate coupling and the cover are positioned in the carrier on the side located opposite the flange and the base.

Abstract:
The invention relates to an axially adjusting device for actuating a multiple disk clutch in the drive train of a motor vehicle. Said adjusting device comprises a housing (4) with a longitudinal axis (A) and a ball ramp arrangement (1) having a support disk (17) that is axially and radially supported in the housing (4) and an axially displaceable adjusting disk (16). The supporting disk (17) is secured against rotation in the housing (4) and, in a first lateral face (23), has first ball tracks (24) of varying depth in the peripheral direction. The adjusting disk (16) can be rotatingly driven and, in a second lateral face (25) opposite the first lateral face (23), has second ball tracks (26) of varying depth in the peripheral direction. The ball tracks (24, 26) define one pair each with opposed slopes and receive one ball (27) each. The adjusting disk (16) is axially supported on the multiple disk clutch (2) and axially and radially mounted by means of the balls (27) retained in the ball tracks (24, 26).
Abstract:
A coupling device with two parts which are coaxially rotatable relative to one another, comprising a friction coupling whose friction plates are alternately connected to each of the rotatable parts. Further the coupling device comprises an actuating device for the friction coupling, which comprises an annular chamber formed in one of the rotatable parts and containing a highly viscous fluid. A rotational member is arranged in the annular chamber and is drivingly connected to the other one of the rotatable parts. The actuating device, when the rotatable parts rotate relative to one another, causes an increase in pressure of the highly viscous fluid for the purpose of loading the friction coupling. When the relative rotation between the rotatable parts exceeds a given value, the increase in pressure is checked to limit the torque transferred through the friction coupling.
