Patent ID: 8894532

Claim:
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 , 5 A, 5 C) being disposed at least partially axially movable within the shaft in order to move a shifting claw ( 9 , 9 A, 9 C) of the dog clutch into a disengaged state and an engaged state, the shifting claw ( 9 , 9 A, 9 C) being rotationally fixed to the shaft so as to rotate with the shaft and being axially movable along the shaft, the actuating piston ( 5 , 5 A, 5 C) being pressurized on both sides, with a pressurizing medium, such that the actuating piston ( 5 , 5 A, 5 C) being hydraulically actuated in two opposed directions, and the actuating piston ( 5 , 5 A, 5 C) being guided, at least to some extent, in a central bore ( 6 ) provided in an interior of the shaft, a first piston chamber ( 7 , 7 A, 7 C) of the actuating piston ( 5 , 5 A, 5 C) being pressurizable with pressurizing medium for disengaging the dog clutch, and a second piston chamber ( 8 , 8 A, 8 C) of the actuating piston ( 5 , 5 A, 5 C) 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.
