Abstract
A sensor for measuring an angle of rotation, and in particular the instantaneous angle of rotation of a rotatable member such as a steering column of a motor vehicle, is especially applicable in a power steering mechanism for a motor vehicle and includes a first wheel, the movement of which serves for measuring the angle of rotation and its direction. The sensor further includes a second wheel which is mechanically linked with but movable relative to the first wheel, the displacement of the second wheel being an indication of the number of rotations effected about an axis by the first wheel, and/or an indication of the direction of the rotation.
