Принадлежит:

The invention provides a position sensor which is used for sensing the position of a speed changer component and outputting a position signal. The position sensor comprises an expansion bolt assembly, a signal assembly and sensors. The expansion bolt of the expansion bolt assembly is supported in an expansion bolt shell and is effectively connected with and drives a telescopic handle to linearly move in a reciprocating way. The expansion bolt is pre-compressed relative to the speed changer component. The signal assembly is provided with a blind hole accommodating telescopic handle. The position sensor is characterized by further comprising a signal conversion calibration module. The sensors are distributed at the periphery of a blind hole so as to sense the position of the telescopic handle linearly moving in the blind hole in the reciprocating way. The signal conversion calibration module is connected between the sensors and a connector assembly so that the position sensor is enabled to ...
