1. An arrangement comprising:
at least one dog clutch for shiftable coupling and decoupling at least one shaft with at least one component of a multi-gear transmission, an actuating piston (5, 5A, 5C) being disposed at least partially axially movable within the shaft in order to move a shifting claw (9, 9A, 9C) of the dog clutch into a disengaged state and an engaged state, the shifting claw (9, 9A, 9C) being rotationally fixed to the shaft so as to rotate with the shaft and being axially movable along the shaft, the actuating piston (5, 5A, 5C) being pressurized on both sides, with a pressurizing medium, such that the actuating piston (5, 5A, 5C) being hydraulically actuated in two opposed directions, and the actuating piston (5, 5A, 5C) being guided, at least to some extent, in a central bore (6) provided in an interior of the shaft, a first piston chamber (7, 7A, 7C) of the actuating piston (5, 5A, 5C) being pressurizable with pressurizing medium for disengaging the dog clutch, and a second piston chamber (8, 8A, 8C) of the actuating piston (5, 5A, 5C) being pressurizable with pressurizing medium for engaging the dog clutch, a physical tube (10) being connected to a pressurizing medium supply channel (11), the tube (10) being press fit into and fixed to a hub (14) and the hub (14) being fixed to a housing, and the tube (10) being guided through the actuating piston (5) into the first piston chamber (7) for pressurizing the actuating piston (5) with pressurizing medium and disengaging the dog clutch. |
