The present invention relates to a PTU switching device. More specifically, the present invention relates to the PTU switching device, moving a pork forward by using a linear actuator only when coupling between an input shaft and an output shaft is released and moving the pork rearward by using an elastic force of a spring when the input shaft and the output shaft are coupled in order to improve response performance of the pork and prevent a loss of fuel efficiency caused by power consumption. 본 발명은 PTU 절환장치에 관한 것으로, 보다 구체적으로는 인풋 샤프트와 아웃풋 샤프트 간의 결합을 해제할 때에만 리니어 엑츄에이터를 이용하여 포크를 순방향으로 이동시키고, 인풋 샤프트와 아웃풋 샤프트 간의 결합을 체결할 때에는 스프링의 탄성력을 이용하여 포크를 역방향으로 이동시킴으로써, 포크의 응답성능을 향상시키고, 전류소모에 의한 연비손실을 방지할 수 있는 리니어 엑츄에이터를 이용한 PTU 절환장치에 관한 것이다.
