Magnet unit for a sensor device of a motor vehicle, sensor device having a magnet unit and motor vehicle having a sensor device

A magnet unit for a sensor device for acquiring a measured variable that characterizes a rotational state of a steering shaft of a motor vehicle, the magnet unit comprising:

• a sleeve;
• and
• a magnet element that is connected in a positive-locking manner to the sleeve,
• wherein the sleeve comprises a bush-shaped attaching section for connecting the magnet unit to a first part of the steering shaft and a connecting flange that extends outwards in the radial direction and comprises at least one cut-out having a radial outer face for connecting to the magnet element,
• wherein the magnet element comprises a magnetically-effective magnet section and at least one connecting element that extends in the axial direction and comprises a radial inner face for connecting to the sleeve,
• wherein when the magnet unit is being used in the state of use in accordance with a function of the magnet unit, at least one connecting element of the magnet element extends through at least one cut-out in the connecting flange of the sleeve and is configured in such a manner that the connecting element of the magnet element forms a positive-locking connection in the tangential direction and in the axial direction with the connecting flange of the sleeve,
• wherein the magnet unit is configured so that in at least one operating state, in a reference state in the case of a reference ambient temperature, the radial inner face at least of one connecting element is spaced in the radial direction with respect to the radial outer face of the associated cut-out of the connecting flange of the sleeve.
