  • Drive unit for a motor vehicle
    Patent number: 7640829
    Abstract: A drive unit for a motor vehicle, having an engine unit and an axle differential arranged on the engine unit, as well as having drive shafts for the vehicle wheels disposed at least partially in the crankcase. The separating plane between the crankcase bottom part and the oil bearing housing of the crankcase acts as the bearing for at least one drive shaft.
    Type: Grant
    Filed: March 9, 2006
    Date of Patent: January 5, 2010
    Assignee: Dr. Ing. h.c. F. Porsche Aktiengesellschaft

  • Gearshift transmission for a motor vehicle with hydraulically actuated multiple clutch
    Patent number: 7147095
    Abstract: A gearshift mechanism for a motor vehicle with hydraulically actuated multiple clutch, particularly a twin clutch, has a first gear input shaft to drive a first group of gears and a second gear input shaft to drive a second group of gears. The two gear input shafts are each assigned a clutch unit being coaxial to one another. A stationary housing accommodates the two clutch units. At its end face, the housing can be closed off by a housing cover that has a central opening through which a drive hub of a clutch cage is guided. The housing cover is provided with a bearing flange around the central opening, on the outside of which the clutch cage is supported. This advantageously supports the clutch on the housing and makes it possible to achieve a support effect for a dual mass flywheel or the crankshaft end of the internal combustion engine.
