Abstract
A torque sensor comprises a freewheel with a first rotating element for transferring a torque to be determined to a second rotating element which is coaxial to the first rotating element, the transfer occurring in one rotational direction, and devices for determining a rotation of the first rotating element relative to the second rotating element in said rotational direction and for determining the torque using the determined relative rotation.
Claims16
A torque sensor comprising:
- a freewheel with a first rotating element for transferring a torque to be determined to a second rotating element which is coaxial to the first rotating element, said freewheel being adapted to transfer said torque in one rotational direction only;
- and
- devices for determining a rotation a of the first rotating element relative to the second rotating element in said rotational direction as well as for determining the torque using the determined relative rotation;
- and
- wherein the devices for determining the relative rotation of the rotating elements serve to determine the rotational angle of the rotating elements independent of one another, said relative rotation being determined as the difference between the rotational angles of the rotating elements.
