The present invention relates to a variable width steering system for tractor wheels. The variable width steering system includes: a main base member installed on the bottom of a tractor; a pair of wheel members installed on both sides of the main base member to be steerable; a pair of variable control members installed on the front side of the main base member symmetrically to each other so as to control the width between a pair of the variable control members; a guide member installed in the main base member to be movable so as to change the width between the wheel members in accordance with the operation of the variable control members; and a variable link member installed on the bottom of the main base member to be rotatable so as to change the width between a pair of the wheel members in accordance with the operation of the guide member. Therefore, when a tractor is driving in farmland, the width between front wheels or rear wheels of the tractor (or a wheel track) can be controlled in accordance with the distance between ridges, and thus, the shape of the ridges can be maintained in accordance with the driving of the tractor, and the tractor can be steered in a desired direction even in a state in which the wheel track of the wheel members is controlled.

    트랙터 바퀴의 가변폭 조향장치에 관한 것으로, 트랙터의 저면에 설치되는 메인베이스부재; 상기 메인베이스부재의 양측에 조향 가능하게 설치되는 한 쌍의 바퀴부재; 상기 한 쌍의 바퀴부재의 폭을 조절하도록 상기 메인베이스부재의 전면에 서로 대칭되게 설치되는 한 쌍의 가변조절부재; 상기 가변조절부재의 작동에 따라 상기 바퀴부재의 폭을 가변시키도록 상기 메인베이스부재의 내부에 이동 가능하게 설치되는 가이드부재; 상기 가이드부재의 이동에 따라 상기 한 쌍의 바퀴부재의 폭이 조절되게 상기 메인베이스부재의 저면에 회전 가능하게 설치되는 가변링크부재;를 마련하여 트랙터의 경작지 주행 시 두둑의 간격에 따라 트랙터의 전륜 또는 후륜의 폭(또는 윤거)를 조절할 수 있고, 이로 인해 트랙터의 주행에 따라 두둑의 형상을 유지할 수 있으며, 바퀴부재의 윤거가 조절된 상태에서도 트랙터를 원하는 방향으로 조향할 수 있다는 효과가 얻어진다.
