The invention provides a steering wheel-free automatic driving steering mechanism which comprises a motor, a small belt wheel, a large belt wheel, a synchronous belt, a connecting shaft, a steering gear box, a radar, a central processing unit, a steering angle sensor and a motor driver, an output shaft of the motor is connected with the small belt wheel, the synchronous belt is connected with the small belt wheel and the large belt wheel, the large belt wheel is connected with the steering gear box through the connecting shaft, the central processing unit is connected with the radar, the steering angle sensor and the motor driver, the radar is connected with the steering angle sensor, the radar detects the external environment and obstacles and sends signals to the central processing unit, the steering angle sensor obtains the steering angle of a vehicle and feeds back the steering angle to the central processing unit, the central processing unit sends a steering control signal to the motor driver, and the motor driver drives the motor to rotate according to the steering control signal. A steering wheel, an electromagnetic clutch, a universal coupling and the like are omitted, the cost of an automatic driving steering mechanism is reduced, the size is small, and unmanned driving steering is achieved.

    本发明提供了一种无方向盘自动驾驶转向机构,包括电机、小带轮、大带轮、同步带、联接轴、方向机、雷达、中央处理器、转向角度传感器和电机驱动器,电机的输出轴与小带轮连接,同步带分别连接小带轮和大带轮,大带轮通过联接轴与方向机连接,中央处理器分别与雷达、转向角度传感器和电机驱动器连接,雷达与转向角度传感器连接,雷达探测外部环境和障碍并发送信号给中央处理器,转向角度传感器获取车辆的转向角度并反馈给中央处理器,中央处理器发送转向控制信号给电机驱动器,电机驱动器根据转向控制信号驱动电机转动。本发明取消了方向盘、电磁离合器、万向联轴器等,降低了自动驾驶转向机构成本,体积小,实现无人驾驶转向。
