Sensor arrangement for detecting torque at steering column of motor vehicle, has sensor device detecting measured values based on electromagnetic field caused by magnet, and transmission module wirelessly sending detected values to receiver

摘要

The arrangement has a torsion bar (16) arranged between an input shaft (12) and an output shaft (14). Multiple magnets (15) are provided at the input or output shafts. A sensor device is arranged on an opposite-lying output shaft and/or input shaft for detecting measured values based on an electromagnetic field caused by the magnets. The device comprises a transmission module (22) for wirelessly sending the detected measured values to a receiver, and an energy module (24) is energized for supplying to the transmission module. A receiver module (26) is arranged at a housing in a motor vehicle.
