The invention relates to a shifting arrangement (10) for displacing a selector fork (44) of a multispeed transmission assembly (58) along a selector rod (48). Said shifting arrangement (10) comprises a positioning element (38) which is mounted so as to be rotatable about an axis (38). The positioning element (38) is connected to the selector fork (44), which is movably mounted on the selector rod (48), via a driving mechanism (18) designed for converting the rotational movement of the positioning element (12) into a sliding movement of the selector fork (44) along the selector rod (48). The shifting arrangement (10) further comprises a locking device (50) for locking the selector fork (44) in selected operating positions. The locking device (50) is designed for establishing a locking connection between the positioning element (12) and the selector fork (44).
Shifting arrangement (10) for displacing a selector fork (44) of a multispeed transmission assembly (58) along a selector rod (48), with a positioning element (12) rotatable about an axis (38) and connected to selector fork (44) movably mounted on selector rod (48), via a drive mechanism (18) which is furnished to convert the rotational movement of positioning element (12) into a translational movement of selector fork (44) along selector rod (48), and with a locking device (50) for locking selector fork (44) in selected actuating positions, characterized in that locking device (50) is designed in order to create a locking connection between positioning element (12), or an element moving with positioning element (12), and selector fork (44), or an element moving with selector fork (44).
Transmission assembly (58), in particular for the drivetrain of a utility vehicle, with a first shaft (62) on which a speed change gear (64, 66) is rotatably mounted, a second shaft (78) that bears a gearwheel (74, 76) meshing with speed change gear (64, 66), a selector sleeve (68), mounted displaceably with respect to first shaft (62), that produces a torque-conductive connection between first shaft (62) and speed change gear (64, 66) in a first position, which connection is broken in a second position of selector sleeve (68), wherein selector sleeve (68) cooperates with a selector fork (44) that can be moved between the first and the second position by a shifting arrangement (10) according to one of the previous claims.
