The present invention relates to a steering system for steering an electric cart. A steering handle is connected to an upper part of a steering shaft for easy movement. A lower part of the steering shaft is connected to a gearbox mounted on a support plate. An operating plate having a reduced thickness while occupying a small space is erected on a drive shaft connected to the rear surface of the gearbox. Thus, the distance between a footrest corresponding to the seat of a driver and a body is decreased to the maximum to reduce the distance between front and rear axles. As result, a reduced radius of rotation facilitates a change of direction in a narrow space. Connecting rods are coupled to both sides of an upper part of the operating plate so that the connecting rods can be easily moved by operating shafts, and thus the rotary motion of the operating plate can be converted into a linear motion. Ends of the connecting rods are coupled to front parts of upper surfaces of covers coupled to wheels so that the ends can be easily moved by both motion shafts thereof. Thus, both the wheels can be steered by the linear motion of the connecting rods. Central shafts as the center of rotation are coupled to rear parts of upper surfaces of both the covers so that the covers coupled to the motion shafts can rotated around the central shafts. The central shafts are coupled to insertion pipes vertically installed on both sides of the support plate, for easy movement, to be supported thereon.

    본 발명은 전동 운반차의 이동 방향을 조향하는 조향장치에 관한 것으로 특히, 조향축 상측부에 조향핸들을 유동용이토록 연결시키고 조향축의 하측부는 지지판에 장착된 기어박스와 연결시킨 다음 기어박스의 후측면으로 연결되는 구동축상으로 적은 공간을 차지하면서 얇은 두께로 작동판을 입설하여 운전석에 해당하는 발판과 본체 사이의 간격을 최대한으로 좁혀 앞,뒷차축간의 거리를 줄여줌으로서 줄여진 회전반경에 의해 협소한 공간내에서의 방향 전환이 용이하도록 하고 작동판의 상부 양측에 연결봉들을 작동축들에 의해 유동용이토록 결합시켜 작동판의 회전운동을 직선운동으로 전환시킬 수 있도록 하며 바퀴를 결합하고 있는 커버의 상면 전방부에 연결봉들의 끝단부를 양측의 운동축에 의해 유동용이토록 결합시켜 연결봉들의 직선운동에 의해 양측 바퀴들을 조향시킬 수 있도록 한 다음 양측 커버의 상면 후방부에 회전 중심이 되는 중심축을 결합하여 운동축들이 결합된 커버들이 이 중심축을 중심으로 회전할 수 있도록 하고 지지판의 양측부에 수직 입설되는 삽입관에 중심축들을 유동용이토록 결합시켜 지지시킬 수 있도록 된 전동운반차의 조향장치를 제공한다.
