Patent ID: 8601893

Claim:
A transmission device ( 1 ) comprising: at least one shift element ( 3 , 4 ) being actuatable via an actuator ( 6 ) comprising at least one electrical component ( 5 ), the electrical component ( 5 ) being connected to a transmission shaft ( 7 ) and being operatively connected to at least one further component of the transmission device ( 1 ) via an electrical transmitting device ( 8 ); the electrical component ( 5 ) and a pump device ( 9 A, 9 B) connected to the transmission shaft ( 7 ) both rotating during operation around the transmission shaft ( 7 ) at a rotational speed of the transmission shaft ( 7 ); a hydraulic actuating pressure, for actuating the shift element ( 3 , 4 ), being generated via the electrical component ( 5 ); electrical energy being inductively exchanged between the at least one further component of the transmission device ( 1 ) and the at least one electrical component ( 5 ) connected to the transmission shaft ( 7 ); the electrical component ( 5 ) comprising an electric machine ( 5 A, 5 B) which drives the pump device ( 9 A, 9 B); and the actuator ( 6 ) comprising a hydraulic fluid accumulator ( 10 A, 10 B) being operatively connectable to a pressure compensation space ( 27 ) of the shift element ( 3 , 4 ).
