A torsion module includes first and second rings ( ) and a spoked wheel ( ). The first ring is attachable to a steering wheel ( ). The spoked wheel is attached on top and bottom sides to the rings and has bending spokes which join a rim to a hub. The bending spokes bend in response to rotation angle offset between the hub and rim caused by torque on the steering wheel. A sensor, placed on a bending spoke, generates a signal indicative of bending experienced by the bending spoke in response to rotation angle offset between the hub and rim. The spoked wheel includes bending-resistant limit stop spokes each having a free end. The free ends engage the rim to limit rotation angle offset between the hub and rim. The rings have axially separated limit stops which enclose the free ends to prevent axial movement between the hub and rim.

A steering angle sensing system for measuring the angle position of a vehicle steering wheel is disclosed which uses at least one position magnet coupled to the rotary movement of the steering wheel as a transducer, and a magnetostrictive transducer as a measuring device. Magnetostrictive transducer includes an elongated, magnetostrictive waveguide extending over a defined arc section, with mode converter for detecting magnetostrictively generated voltage pulses at one end. The waveguide is stationary related to the rotary movement of at least one position magnet; , so that, when turning the steering wheel, the magnet field of one position magnet is applied to waveguide in different positions dependent of the position of the steering wheel.

A steering wheel angle sensor includes first and second sensors, a differential gear, and a detector. The first sensor determines steering wheel angular position within one revolution and the second sensor determines number of steering wheel revolutions. The first sensor has a first rotor carrying a first coding. The first rotor and the first coding rotate as the steering wheel rotates. The second sensor has a second rotor and a second coding movable by the second rotor. The gear includes driving, reference, and planetary wheels for coupling the rotors such that the rotors rotate at different speeds with respect to one another as the steering wheel rotates. The second rotor engages with a pivoted lever into an arm carrying the second coding such that the second coding pivots as the second rotor rotates. The detector scans the first coding within an angular segment of the steering wheel range of rotation as the first coding rotates. The detector scans the second coding within the steering wheel range of rotation as the second coding pivots while the second rotor rotates in order to determine the angular position of the steering wheel.
