Single motor drive steering frame

The utility model relates to a single-motor drive steering support, wherein a drawing device of single motor is mounted under a frame of the steering support, the output shaft of single motor is arranged along the longitudinal central line of the steering support, while two ends of the output shaft are respectively connected with a universal shaft, another side ends of the two universal shafts are respectively connected with a vehicle shaft gear box, and the two vehicle shaft gear boxes are respectively mounted on the front and back vehicle shafts of the steering support. The utility model uses single motor to drive the steering support along orbit, to reduce the motor volume and the space occupied by the motor, thereby reducing the horizontal width of the steering support to meet the design demand of steering support of narrow-orbit vehicle. The utility model can effectively reduce the height and load of steering support, to improve the speed of narrow-orbit vehicle.
