ABSTRACT:
A shifting device (1) for shifting a motor vehicle transmission with a shift selector shaft on which a plurality of shift elements (2) such as shift forks or shift rockers (3) are arranged and can be displaced to carry out a shifting operation. The shifting device (1) includes one hydraulic shift cylinder (5, 11, 18, 25), that can be actuated from both sides, with a piston (9, 15, 16, 19, 26) that can be displaced within a cylinder housing (6) and which is actively connected with a shift element (2) to be actuated. To simplify a shifting device (1) of this type, the piston (9, 15, 16, 19, 26) has a piston rod (10, 17, 23, 29) that follows the movement of the piston (9, 15, 16, 19, 26) and can be connected directly to the shift element (2) in a detachable manner.
