Abstract:
1. A transmission unit, comprising: a pump having a pump casing and a planetary wheel set in the pump casing, the planetary wheel set having a plurality of gearwheel elements, the pump being configured to deliver, via the gearwheel elements, a hydraulic fluid from a suction zone to a pressure zone of the pump casing; a controllable throttling device between adjacent gearwheel elements and configured to selectively throttle fluid flow between the suction zone and the pressure zone and thereby to brake the gearwheel elements relative to one another, the throttling device including a valve moveable by centrifugal force, the valve including a rotatable shutoff element configured to be latched between a first end position and a second end position; a fluid reservoir in the pump casing in spaces between adjacent gearwheel elements, and configured for simultaneous fluidic connection to the suction zone and to the pressure zone via the controllable throttling device; and a synchronizer ring configured to couple the rotatable shutoff elements to one another.
