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.

Steering angle sensor

In one form, the invention relates to a transmission device for transmitting an electric current to a component of a steering wheel of a motor vehicle, including a rotor which is to be arranged on the steering wheel such that it is rotatable along with the steering wheel; a stator which is to be arranged on a component of the vehicle that is stationary as compared to a rotary movement of the steering wheel; at least one conductor element by which the rotor is electrically connected with the stator; and a temperature determination device for determining the temperature of the conductor element or in the region of the conductor element. In another form, the invention also relates to a method for transmitting an electric current to a component of a steering wheel of a motor vehicle.

A steering angle sensor for motor vehicles for determining the steering angle of a steering element of a steering wheel assembly, which is rotatable during a steering movement is provided. The steering angle sensor comprises a rotatably mounted drive element which during a rotary movement of the steering element likewise performs a rotary movement, and a rotatably mounted driven element which is in engagement with the drive element and is driven by the same. The steering angle is determined by detecting the rotary movement and/or the angle of rotation of the driven element. The drive element and/or the driven element include elastic means via which the drive element and the driven element are braced against each other.

Steering angle sensor for motor vehicles

An optical steering angle sensor for determining the absolute value of the steering angle even when a steering wheel has been revolved several times is provided, having a stator, a rotor with a barcode and evaluation electronics. In one form, the invention provides for the rotor to have a track groove which is arranged in the form of a worm in order to determine the number of revolutions, which track groove has an associated driver finger on the stator, which engages in the track groove and is arranged in a bearing such that it can pivot, and has a holder for a magnet which can pivot with the driver finger and which driver finger has an associated stationary Hall sensor, which is provided in an evaluation circuit.
