The present invention relates to a steering actuator for active steering control of railway vehicles. The steering actuator of the present invention comprises: a case fixated to a bogie side frame of a railway vehicle as one body; a first link whose one end is combined with one side in the case with a hinge; a second link whose one end is combined with the other side in the case with a hinge and whose other end is combined with one side of a housing with a hinge; a link operating means for moving a piston link forward and backward, which is placed to protrude to the other side of the housing and is combined with the other end of the first link with a hinge; a front steering link whose one end is combined with the middle part of the first link with a hinge and whose other end is combined with one side of a front axle box supporting a front wheel and axle with a hinge; and a rear steering link whose one end is combined with the middle part of the second link with a hinge and whose other end is combined with one side of a rear axle box supporting a rear wheel and axle with a hinge. According to the present invention, stable steering of a wheel and axle is possible by fixating the steering actuator on a bogie side frame, combining the front and the rear steering links on both sides with one side of a front and rear axle boxes with a hinge, and simultaneously controlling the steering of a front wheel and axle and a rear wheel and axle.
본 발명은 철도차량용 능동 조향 제어를 위한 조향 액추에이터 장치에 관한 것으로; 철도차량의 대차 사이드프레임에 일체로 고정되는 케이스와, 상기 케이스 내부 일측에 일단부가 힌지결합되는 제1 링크와; 상기 케이스 내부 타측에 일단부가 힌지결합되는 제2 링크와, 하우징의 일측은 상기 제2 링크의 타단부에 힌지결합되고 상기 하우징의 타측으로 돌출구비되어 상기 제1링크의 타단부에 힌지결합되는 피스톤 링크를 전후진시키는 링크 작동수단과, 상기 제1 링크의 중간부에 일단부가 힌지결합되고 타단부는 전방 윤축을 지지하는 전방 액슬박스의 일측에 힌지결합되는 전방 조향링크와, 상기 제2 링크의 중간부에 일단부가 힌지결합되고 타단부는 후방 윤축을 지지하는 후방 액슬박스의 일측에 힌지결합되는 후방 조향링크로 구성되는 것을 특징으로 한다. 본 발명에 따르면, 대차 사이드프레임에 조향 액추에이터 장치를 고정하고 양측의 전방 및 후방 조향링크를 전방 및 후방 액슬박스의 일측에 힌지결합하여 전방 및 후방 윤축의 조향을 동시에 조정함으로서 안정적인 윤축의 조향이 가능하다.
