The invention provides an electric steering wheel and a wheel type agricultural machine steering system. Comprising a steering wheel, a handball, a rotating shaft, a planetary gear set, an electromagnetic clutch, an electric slip ring, a torque motor mounting shell, a torque motor, a through type encoder, a controller board, a torque motor driver, a steering transmission shaft, a steering wheel deflection angle detection device, a full-hydraulic steering device and a steering oil cylinder oil supplementing device. Through the design of the steering oil supplementing loop, the defect that the stroke of the steering oil cylinder is insufficient due to internal leakage of the full-hydraulic steering gear is overcome. A PD control mode is adopted, and whether the steering wheel is manually operated or electrically controlled, the deflection angle of the steering wheel and the rotation angle of the electric steering wheel have a determined corresponding relation. When the steering wheel is manually operated, a driver can sense the wheel deflection angle and the vehicle body posture through the handball phase, and the operation experience of the wheeled agricultural machine is improved.

    本发明提供了一种电动方向盘及轮式农机转向系统,包括方向盘、手球、转轴、行星齿轮组、电磁离合器、电滑环、力矩电机安装壳、力矩电机、贯通式编码器、控制器板、力矩电机驱动器、转向传动轴、转向轮偏角检测装置、全液压转向装置和转向油缸补油装置;本发明通过转向补油回路设计,弥补了全液压转向器的内部泄露导致的转向油缸行程不足的缺陷。采用PD控制方式,无论是手动操作方向盘还是电动控制方向盘,转向轮偏角与电动方向盘转角均具有确定对应关系。当手动操作方向盘,驾驶员通过手球相位即可感知车轮偏转角和车身姿态,提升了轮式农机的操作体验。
