  • Patent number: 8668615
    Abstract: A drive assembly for a motor vehicle driven by a plurality of axles includes a differential unit, an externally controllable hang-on coupling, an externally controllable locking coupling, a first hydraulic actuating unit, and a second hydraulic actuating unit. The differential unit includes an input part that is rotatably drivable around an axis of rotation, and two output parts drivingly connected to the input part. The hang-on coupling drivingly connects the differential unit and a driveshaft. The locking coupling locks the differential movement between the two output parts of the differential assembly. The first hydraulic actuating unit actuates the hang-on coupling and the second hydraulic actuating unit actuates the locking coupling. The first hydraulic actuating unit, the hang-on coupling, the second hydraulic actuating unit and the locking coupling are arranged coaxially relative to the axis of rotation.

  • Publication number: 20110275467
    Abstract: The disclosure relates to a drive assembly for a motor vehicle driven by a plurality of axles. The drive assembly comprises a differential unit, an externally controllable hang-on coupling, an externally controllable locking coupling, a first hydraulic actuating unit, and a second hydraulic actuating unit. The differential unit includes an input part which is rotatably drivable around an axis of rotation A, and two output parts which are drivingly connected to the input part. The two output parts have a differential effect relative to one another. The externally controllable hang-on coupling drivingly connects the differential unit and a driveshaft. The externally controllable locking coupling locks the differential movement between the two output parts of the differential assembly. The first hydraulic actuating unit actuates the hang-on coupling and the second hydraulic actuating unit actuates the locking coupling.

  • Patent number: 7846056
    Abstract: A drive assembly for use between an axle differential and a sideshaft comprises an intermediate shaft that is rotatably supported around a rotation axis and has a first end fixedly connected to an output gear of the axle differential and a second end fixedly connected at least indirectly to the sideshaft. A controllable coupling unit comprises a coupling cage with outer plates and a coupling hub with inner plates. The coupling cage is rotatably supported around the rotation axis relative to a bearing support. The coupling hub is connected to the intermediate shaft. The outer plates and the inner plates are arranged so as to axially alternate and jointly form a plate package. The coupling cage extends in the axial direction from the differential carrier to the bearing support and is sealed by first and second rotary seals.

  • Patent number: 7677374
    Abstract: A method of determining the coupling moment in a friction coupling with an electro-mechanical actuator which comprises a supporting element axially supported in a housing and a displaceable setting element axially supported on said supporting element, wherein the supporting element is axially supported in the housing via an undisplaceably enclosed hydraulic medium and that the pressure in the hydraulic medium is measured and used by lookup tables of values for the actuator and for the friction coupling for the purpose of calculating the coupling moment in a central ECU.

  • Publication number: 20070270264
    Abstract: A hydrostatic coupling assembly for use in the driveline of a motor vehicle includes a first coupling part (3) and a second coupling part (4); a displacement machine (22) having a first rotor (23) which is eccentrically supported relative to one of the coupling parts (3, 4), and a second rotor (25) which is connected to the other one of the two coupling parts (3, 4). The first rotor (23) and second rotor (25) form displacement chambers (31) for hydraulic fluid thereby creating a pump. An annular chamber (50) communicates with the displacement chambers through first and second connecting channels (34, 35). A sliding sleeve (38) is axially displaceable between an open and closed position in which the outlets of the first and second connecting channels (34, 35) in the annular chamber (50) are open or closed, respectively.

  • Publication number: 20070193846
    Abstract: An axial setting device for actuating a multi-plate coupling (2) in the driveline of a motor vehicle, comprising a housing (3), a cylinder unit (15) and a hydraulic system. In the housing (3), two parts (4, 5) are supported so as to be coaxially rotatable relative to one another and can be coupled to one another by a set of coupling plates (10) which are axially arranged between a supporting disc (9) and a pressure disc (11). The cylinder unit (15) comprises a hydraulic chamber (22) and a piston (21) axially displaceably arranged therein for actuating the multi-plate coupling (10) via the pressure disc (11). The hydraulic system for actuating the piston (21) comprises a quantity of oil jointly contained in the housing (3) and in the hydraulic chamber (22), as well as a pump (18) which has a first connection (23) connected to the housing (3) and a second connection (24) connected to the hydraulic chamber (22).

  • Patent number: 6186286
    Abstract: A braking device for wheels of vehicles such as trailers includes a caliper in which brake linings are guided. Between these linings, at least one brake disk is displaceably held on driving toothing of a wheel hub. A pneumatically operable mechanical adjusting device interacts with the brake linings. The braking device includes at least one brake disk in a caliper which is fixed. On one end, the caliper is connected by a fastening element with an axle element of the vehicle. On the caliper, an enclosing housing for bearing the adjusting device is held. By way of a bearing plate, the adjusting device is also supported on the caliper. Pressure pistons of the device are guided by a one-part yoke in a jointly axially adjustable manner and can be acted upon by pressure with respect to the brake linings and the brake disks.
