  • Differential gear unit for motor vehicles having controllable driving power distribution
    Patent number: 8062162
    Abstract: A differential gear unit for motor vehicles for the controllable distribution of the driving power comprises a housing and a differential gear (4) disposed therein, the gear having two speed-changing transmissions (5) drivingly connected to the output shafts (7, 8) and to the input member (14) of the differential gear, and two hydraulically controllable clutches (24, 25).
    Type: Grant

  • Drive unit for motor vehicles with hybrid drive in a longitudinal arrangement
    Patent number: 7661495
    Abstract: A drive unit for motor vehicles with hybrid drive and a drive train in a longitudinal arrangement, between the internal combustion engine and the first axle, comprising a housing piece, a through driveshaft, an electric motor, surrounding the through driveshaft with a first clutch before the electric motor and a second clutch thereafter, whereby a second axle is also to be driven with minimal space requirement. A first electric motor is thus physically combined with the first clutch, surrounding a second electric motor and the through driveshaft and is connected to the second axle by means of a third clutch, an offset gear and a shaft.
