Abstract:
A transmission device (1) including at least one shift element (3, 4) that can be actuated via an actuator (6) having at least one electrical component (5). The electrical component (5) is connected to a transmission shaft (7), rotates during operation at the rotational speed of the transmission shaft (7), and is operatively connected to further components of the transmission device (1), via an electrical transmitting device (8). Electrical energy can be exchanged, at the least, inductively via the transmitting device (8) between the components of the transmission device (1) and the at least one electrical component (5) connected to the transmission shaft (7). Hydraulic actuating pressure can be generated, via the electrical component (5), for actuating the shift element (3, 4).
