  • Patent number: 7507181
    Abstract: A method and device for determining a driving torque correction factor for compensating the driving torques of a drive unit including a first drive device and a second drive device, both of which act with their driving torque on a common drive shaft. The method includes specifying and setting a desired driving torque for one of the two drive devices, adjusting a brake torque for the other of the two drive devices to a brake torque value, which is equivalent to the value of the actual driving torque (that occurs on the basis of the desired driving torque) of one of the two drive devices, and determining the correction value as a function of the specified desired driving torque of the one drive device and as a function of the brake torque value of the other drive device, the brake torque value being adjusted at the time of the compensation of the torques.

  • Patent number: 7258646
    Abstract: Differential gearing for vehicles, having a gearing input and two gearing output shafts which exit on mutually opposite sides of a differential gearing housing from the differential gearing housing, having a differential holder which is arranged in the differential gearing housing in the area between the gearing output shafts, the differential holder being rotatably disposed in the differential gearing housing by means of a ball bearing arrangement which has a bearing prestress. At least one disk spring is provided which generates the bearing prestress of the ball bearing arrangement.
