Abstract:
1. An actuator comprising: a drive device comprising an electromechanical drive; a telescopic device that actuates a brake cable; a displacement sensor unit for detecting the adjustment travel of the telescopic device, comprising a displacement signal sensor and a displacement signal receiver; and a force sensor unit for detecting the force applied to the brake cable by means of the telescopic device, comprising a force signal sensor and a force signal receiver; wherein the displacement sensor unit and the force sensor unit are disposed spatially adjacent to each other in the housing of the telescopic device and separate from the brake cable; wherein the displacement signal sensor is a rotational travel sensor; wherein the force signal sensor is a translation displacement sensor; wherein the force signal sensor and the displacement signal sensor are provided in such a manner that the rotation of the hollow shaft provides a measurement for the adjustment travel of the telescopic device and the translatory motion of the hollow shaft provides a measurement for the force applied, and wherein the adjustment travel of the telescopic device and the force applied to the brake cable are detected in such a manner that the adjustment travel of the brake cable is obtainable by deducting a travel of the hollow shaft detected by the force sensor unit from the adjustment travel of the telescopic device detected by the displacement sensor unit.
