  • Patent number: 9951850
    Abstract: A drive assembly for a motor vehicle has a multi-step transmission and a differential drive. The multi-step transmission comprises a rotatingly drivable driveshaft and an intermediate shaft parallel to the driveshaft, and at least one first transmission stage and a second transmission stage for transmitting torque from the driveshaft to the intermediate shaft with different transmission ratios, as well as a shift unit, wherein the intermediate shaft comprises an output gear for transmitting torque to a differential carrier of the differential drive, wherein a rotational axis of the differential carrier extends parallel to the intermediate shaft, wherein the output gear and the shift unit are arranged axially between the at least two transmission stages, and wherein the driveshaft comprises bores for supplying lubricant.
    Type: Grant

  • Patent number: 8808127
    Abstract: A differential assembly is disclosed, and more particularly a differential assembly for a motor vehicle driving axle drivable by an electric motor. The differential assembly comprises a driving gear; a differential drive with an input part and two output parts, wherein the output parts are drivingly connected to the input part and, relative to one another, have a differential effect; a coupling which is arranged effectively between the driving gear and the differential drive, wherein, in a closed condition of the coupling, torque is transmitted from the driving gear to the differential drive and, in an open condition of the coupling, a transmission of torque is interrupted; a controllable actuator for actuating the coupling and a sensor for determining at least three switched positions of the coupling. Furthermore, a driving assembly with such a differential assembly is also disclosed.
