A shifting device with two positive-locking shifting element halves includes a positive connection between the shifting element halves that is able to be established or released. The respective prevailing operating states of the shifting element halves are determined through a sensor device. The surface areas of an encoder contour relative to a measuring device are formed in a convex or concave manner, whereas a perpendicular gap between the surface areas of the encoder contour and a permanent magnet, starting from a joint area between the surface areas in the direction of an end area of the surface areas increases or decreases in each case.

Shifting device of a vehicle transmission

A component of a transmission device, which rotates around a central axis and is adjustable in an axial direction, includes with an encoder contour on the circumference of the component that interacts with a sensor device. The encoder contour features at least one area provided for calculating the axial position of the component, whereas a surface of the first area is designed with a varying radial extension along the axial direction relative to the central axis. The encoder contour has second areas for calculating the rotational speed of the component, whereas a slope of a radial surface of the second areas in the axial direction is differentiated from a slope of the surface of the first areas in the axial direction. In the circumferential direction of the component, the encoder contour is designed alternately with first areas and second areas.
