Abstract

The invention relates to an actuating device for actuating at least one shifting element (3, 4, 5) shiftable through a shifting device (6, 7, 8), whereas the shifting device (6, 7, 8) features a pressure space (6a, 7a, 8a) with a supply (26) for a pressurized medium, along with a shut-off valve (17).

It is proposed that the shut-off valve (17) is connected in an electrically controllable and torque-proof manner to at least one shifting element (3, 4, 5), and that the electrical energy for the actuation of the shut-off valve (17) is able to be supplied without contact.

Claims

1. Actuating device for actuating at least one shifting element (3, 4, 5) shiftable through a shifting device (6, 7, 8;

48), whereas the shifting device (6, 7, 8, 48) features a pressure space (6a, 7a, 8a) with a supply (26;

49) for a pressurized medium, along with a shut-off valve (17), characterized in that the shut-off valve (17) is connected in an electrically controllable and torque-proof manner to at least one shifting element (3, 4, 5), and that the electrical energy for the actuation of the shut-off valve (17) is able to be supplied without contact.
