Document Type and Number:
WIPO Patent Application WO/2012/084684
Kind Code:
A3
Abstract:
The invention relates to a transmission unit comprising a planetary gear set which comprises a plurality of gear elements and is designed as a pump, which brings about delivery of hydraulic fluid from a suction chamber to a pressure chamber of a pump housing containing the planetary gear set by means of the gear elements. A controllable throttle device is provided for selectively throttling a fluid flow delivered between the suction chamber and the pressure chamber, and for thereby braking the gear elements of the planetary gear set relative to each other. A fluid tank is disposed in an intermediate space of the pump housing formed between a plurality of gear elements of the planetary gear set and can be connected to the suction chamber and the pressure chamber simultaneously by means of the throttle device.
