Abstract
A device for measuring torque in a drive assembly includes a torque-loaded torsion element ( ), such as a shaft, and a reference element ( ) surrounding the torsion element ( ). The reference element is correspondingly tubular in shape. A first tube end ( ) of the reference element ( ) is firmly connected to a first shaft end ( ) of the torsion element ( ). A second tube end ( ) of the reference element ( ) is supported on the second shaft end ( ) of the torsion element ( ). The two tube ends ( ) are each associated with a transmitter element ( ). The relative position of the transmitter elements ( ) in the direction of rotation around the rotational axis ( ) is recorded by a sensor element ( ). The sensor ( ) is associated with a housing ( ). The sensor ( ) generates a signal each time the two transmitter elements ( ) pass and transmits signals to an evaluation unit ( ). The evaluation unit ( ) determines the torque applied from the offset of the signals.
