  • Actuating assembly
    Patent number: 8739953
    Abstract: An actuating assembly for connecting a driving axle in the driveline of a motor vehicle is disclosed. The actuating assembly comprises a pump for generating a hydraulic pressure; a pressure accumulator which can be filled by the pump with a hydraulic fluid for generating a pre-pressure; a first hydraulic actuating unit for actuating a first coupling; a second hydraulic actuating unit for actuating a second coupling; wherein at least one of the two first or second hydraulic actuating units can be loaded by the pressure accumulator with hydraulic pressure and, after the pressure accumulator has been at least partially emptied, can be additionally loaded by the pump, wherein the associated first or second coupling can be actuated in the closing sense. Furthermore, a drive assembly having an inventive actuating assembly is also disclosed.

  • Angle drive assembly
    Patent number: 8661942
    Abstract: An angle drive arrangement for a drive train comprises an input shaft and a shift clutch. The input shaft can be driven about a first rotational axis. The shift clutch is arranged coaxially with respect to the first rotational axis and has a clutch input part and a clutch output part which can be coupled to one another to transmit torque. The angle drive arrangement further includes an angle gearing with a crown gear, which is arranged coaxially to the first rotational axis, and a pinion, which is mounted about a second rotational axis and which is in meshing engagement with the crown gear. The second rotational axis is at a right angle to the first rotational axis. The crown gear is fixedly connected to an intermediate shaft mounted in a housing by first and second bearing mechanisms, which are arranged on the same side of the second rotational axis.

  • Drive assembly with hydraulic actuating mechanism
    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.

  • DRIVE ASSEMBLY WITH HYDRAULIC ACTUATING MECHANISM
    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.

  • PARKING BRAKE ASSEMBLY WITH EMERGENCY UNLOCKING MECHANISM
    Publication number: 20110290615
    Abstract: A parking brake assembly for the driveline of a motor vehicle is disclosed. The parking brake assembly comprises a locking mechanism, an actuator and an unlocking mechanism. The locking mechanism is able to inhibit and release the rotational movement of a shaft in the driveline of a motor vehicle. The actuator actuates the locking mechanism. The locking mechanism comprises a locking element which is linearly movable by the actuator, and a latching element which cooperates with the locking element. The locking element can be transferred into a first axial position in which the latching element assumes a releasing position in which the shaft is rotatable, and wherein the locking element can be transferred into a second axial position in which the latching element assumes a closing position in which the latching element inhibits a rotational movement of the shaft. The unlocking mechanism forcibly unlocks the locking mechanism.
