Document Type and Number:
WIPO Patent Application WO/2019/013514
Kind Code:
A1
Abstract:
An actuator system for an electric vehicle is disclosed. According to an embodiment of the present invention, the actuator system for the electric vehicle comprises: an actuator motor having a rotary shaft; a speed reduction part detachably coupled to the rotary shaft, reducing the speed of rotation power transmitted from the rotary shaft so as to form a set reduction ratio, and including a fork driving shaft rotating according to the speed-reduced rotation power, and a linearly moving part coupled to the fork driving shaft so as to linearly move the fork driving shaft according to the rotational direction of the fork driving shaft; and a shift part including a shift fork detachably coupled to the linearly moving part so as to linearly move according to a linear movement of the linearly moving part, and a sleeve coupled to the shift fork and linearly moving at a set position according to the linear movement of the shift fork so as to be coupled to and released from a first-stage gear or a second-stage gear such that a first-stage shift gear or a second-stage shift gear is implemented.
