Abstract
The disclosure relates to a shifting arrangement for displacing a selector fork of a multispeed transmission assembly along a selector rod. The shifting arrangement has a positioning element which is mounted so as to be rotatable about an axis. The positioning element is connected to the selector fork, which is movably mounted on the selector rod, via a driving mechanism designed for converting the rotational movement of the positioning element into a sliding movement of the selector fork along the selector rod. The shifting arrangement further comprises also has a locking device for locking the selector fork in selected operating positions. The locking device is designed for establishing a locking connection between the positioning element and the selector fork.

A shifting arrangement for displacing a selector fork of a multispeed transmission assembly along a selector rod, comprising:
- a positioning element rotatable about an axis and connected to the selector fork which is movably mounted on the selector rod;
- a drive mechanism that converts rotational movement of the positioning element into a translational movement of the selector fork along the selector rod;
- and
- a locking device for locking the selector fork in selected actuating positions;
- wherein the locking device creates a locking connection between the positioning element, or an element moving with the positioning element, and the selector fork, or an element moving with the selector fork;
- and
- wherein the locking device is arranged coaxially to the axis of the positioning element.
The shifting arrangement of 1, wherein the locking device includes a spring and a locking element that is biased by the spring into one of several locking recesses.
A transmission assembly for a drivetrain of a utility vehicle, comprising:
- a first shaft on which a speed change gear is rotatably mounted;
- a second shaft that bears a gearwheel meshing with the speed change gear;
- a selector sleeve mounted displaceably with respect to the first shaft, wherein in a first position the selector sleeve establishes a torque-conductive connection between the first shaft and the speed change gear, and in a second position of the selector sleeve, the torque-conductive connection is broken;
- and
- a shifting arrangement moving the selector sleeve between the first and second positions, the shifting arrangement including:
- a selector rod;
- a selector fork;
- a positioning element rotatable about an axis;
- a drive mechanism that converts rotational movement of the positioning element into a translational movement of the selector fork along the selector rod;
- and
- a locking device arranged coaxially to the axis of the positioning element, the locking device creating a locking connection between the positioning element and the selector fork and locking the selector fork in selected actuating positions.
