Abstract

A goniometric device for measuring an angle such as the angle of rotation of the steering wheel in a motor vehicle is useful for providing a backlash-free reduction ratio of the angular movement to be measured. For this purpose an elastic torque rod is used to one end of which the angular movement is applied and the other end of which is rigidly fixed. The angular movement of a tap is taken off at a tap location between the two ends. The reduction ratio depends on the ratio between the two distances from the tap to both ends of the torque rod.
