Abstract
A shift track selection rod and a shifting element are provided which can be connected to one another without additional fastening elements. A system consists of the shift track selection rod and the shifting element. A transmission actuator includes the system. A transmission includes the system or the transmission actuator.
Claims16
A shift track selection rod mounted on a shifting element, comprising:
- an axis and a connection geometry of the shift track selection rod, wherein the axis and the connection geometry fix the shifting element via a positive locking at a position along the axis, wherein
- the connection geometry is configured so as not to hinder a rotational movement of the shifting element, about the axis of the shift track selection rod, for a shifting movement to select a shift track at least over an angular range, without the fixing being released along the axis, and
- the shift track selection rod is provided rotationally fixedly about its axis, in a transmission actuator.
A shifting element which is designed to be fixed onto a shift track selection rod along an axis of the shift track selection rod, comprising:
- a correspondence geometry of the shifting element, wherein the correspondence geometry fixes the shifting element at a position along the axis of the shift track selection rod, wherein
- the correspondence geometry is configured so as not to hinder a rotational movement of the shifting element, about the axis of the shift track selection rod, for a shifting movement to select a shift track, at least over an angular range without the fixing being released along the axis.
A system, comprising:
- a shift track selection rod mounted on a shifting element, wherein the shift track selection rod has an axis and a connection geometry which fix the shifting element via a positive locking at a position along the axis, wherein
- the connection geometry is configured so as not to hinder a rotational movement of the shifting element, about the axis of the shift track selection rod, for a shifting movement to select a shift track, without the fixing being released along the axis, and the shift track selection rod is provided rotationally fixed about its axis, in a transmission actuator, and
- the shifting element is fixed onto the shift track selection rod along the axis of the shift track selection rod, wherein
- the shifting element has a correspondence geometry which fixes the shifting element at a position along the axis of the shift track selection rod, wherein
- the system is designed for installation in the transmission actuator.
