Abstract

A steering element sensor assembly for sensing a steering torque and an absolute angular position having a circuit board and first and second sensor elements. The circuit board has a base surface arranged perpendicularly to a steering axis and a wing surface angled to the base. The first sensor element determines the steering torque and has a first primary sensor formed as a magnetically coded portion on the steering element and one secondary sensor for converting the changing magnetic field generated by the primary sensor into an electrical signal. The secondary sensor determines the absolute angular position and a main gear arranged on the steering element that meshes with at least two gears, one which has one more tooth than the other. Each gear has a target that faces a respective angle sensor.
