The invention discloses an electric power steering system for an unmanned single-wheel steering vehicle. The power assisting system comprises a power assisting motor, a speed reducing mechanism and anoutput shaft, and the speed reducing mechanism comprises a first worm connected with the power assisting motor, a second worm, a first worm wheel arranged on the second worm and meshed with the firstworm, and a second worm wheel arranged on the output shaft and meshed with the second worm. According to the electric power steering system for the unmanned single-wheel steering vehicle, a two-stageworm and gear speed reducing mechanism is adopted, the structure is more simplified, the size is smaller, the cost is lower, angle closed-loop control is adopted, and the risk of angle distortion iseliminated.

    本发明公开了一种无人驾驶独轮转向车辆用电动助力转向系统,包括助力电机、减速机构和输出轴,所述减速机构包括与所述助力电机连接的第一蜗杆、第二蜗杆、设置于第二蜗杆上且与第一蜗杆相啮合的第一蜗轮和设置于所述输出轴上且与第二蜗杆相啮合的第二蜗轮。本发明的无人驾驶独轮转向车辆用电动助力转向系统,采用二级蜗轮蜗杆减速机构,结构更简化,体积更小,成本更低,采用角度闭环控制,消除角度失真风险。
