The present invention relates to an electric vehicle for minimizing a cornering radius, wherein a cornering radius of the electric vehicle is minimized to 90 degrees so that a direction can be easily changed even in a narrow work space. To achieve this, according to the present invention, in the electric vehicle, a rotation wheel (10) is provided in the front, and two driving wheels (21, 22) rotating by motor operation are individually and rotationally formed about a driving shaft (20) at both sides in the rear. Moreover, a steering shaft (30) is formed for directional rotation in the rotation wheel. An angle sensor (31) is formed to detect directional rotation of the rotation wheel (10) in the steering shaft (30), and both sides of rear driving wheels (20, 30) are operated in a mutual opposite direction by a detection signal of the angle sensor (31).

    본 발명은 회전 반경을 최소화한 일렉트릭 전동차에 관한 것으로서, 전동차의 회전방경이 90도로 최소화되어질 수 있도록 함으로 협소한 작업공간에서도 방향전환이 용이하게 이루어질 수 있도록 하기 위한 것이다. 이를 실현하기 위한 본 발명은, 전방에는 회동바퀴(10)가 구비되고, 후방에는 모터 구동에 의해 회동이 이루어지는 2개의 구동바퀴(21,22)가 양측에서 구동축(20)을 중심으로 개별 회동 가능하게 구성되며, 상기 회동바퀴에는 방향 회동을 위한 조향축(30)이 구성된 일렉트릭 전동차에 있어서, 상기 조향축(30)에는 회동바퀴(10)의 방향 회동을 감지하기 위한 각도센서(31)가 구성되고; 상기 후방 구동바퀴(20,30)는 각도센서(31)의 감지신호에 의해 양측이 상호 반대방향으로 구동이 이루어지는 것을 특징으로 한다.
