  • Publication number: 20170074378
    Abstract: A propulsion device for a vehicle includes a differential gear, which is driven by the electric machine via a planetary gear and operatively connected to an axle on the vehicle, with the planetary gear including at least three rotatable gear elements. A switching device is switchable by an actuator between a first switch position, in which one gear element is secured against a rotation about the axis of rotation, and a second switch position, in which the one gear element is connected by the switching device to another gear element in a torsion-proof manner. A parking brake including at least one parking brake element is movable by the actuator between a park position, in which the vehicle is prevented from rolling away, and at least one release position.

  • Publication number: 20110174103
    Abstract: There is provided a double clutch for connecting a crankshaft of an engine to one of two input shafts of a gearbox for engine torque transmission. The double clutch includes, but is not limited to a first clutch for selectively connecting a first input shaft of the gearbox to the crankshaft, a second clutch for selectively connecting a second input shaft of the gearbox to the crankshaft, and an actuator coupled to both the first clutch and the second clutch. The actuator is operable to move the first clutch and the second clutch between a default position and an activated position. In the default position, the first clutch connects the first input shaft to the crankshaft while the second clutch disconnects the second input shaft from the crankshaft. In the activated position, the first clutch disconnects the first input shaft from the crankshaft while the second clutch connects the second input shaft to the crankshaft. The crankshaft is always connected to one of the input shafts.
