Abstract

A steering angle sensor, equipped for installation in a steering arrangement of a motor vehicle, is provided. The steering angle sensor comprises a rotatably mounted first gearwheel which upon actuation of the steering arrangement rotates about an axis and at least one rotatably mounted second gearwheel which is in engagement with the first gearwheel and is carried along with a rotary movement of the first gearwheel, so that with reference to a rotary movement of the second gearwheel a steering angle of the steering arrangement can be determined. The teeth of at least one of the gearwheels are tapered in axial direction along the tooth width such that a respective tooth of the one gearwheel, which is tapered along the tooth width, with wedge action can be fitted into a tooth gap of the gearwheel in engagement therewith.
