The invention discloses an electric counterbalance forklift and an electric power steering system thereof. The steering system comprises a steering wheel assembly, a steering booster connected to thesteering wheel assembly and a steering axle assembly connected to the steering booster through a steering transmission mechanism. The steering booster comprises a boosting motor, an input shaft, an output shaft and a torsion bar connected between the input shaft and the output shaft, and the output shaft is in transmission connection with the boosting motor; the torsion bar is connected with a torsion sensor, the steering booster is connected with a steering angle sensor used for detecting the rotating angle of the input shaft, and the boosting motor, the steering angle sensor and the torsionsensor are all in communication connection with the steering controller; and the steering controller is used for controlling a power-assisted motor to be powered off when the steering angle sensor detects that the input shaft rotates to a set limit angle. The power-assisted motor drives the steering axle assembly to steer, and electric control steering is adopted to replace hydraulic control, so that the problem of oil leakage can be solved, the environment-friendly effect is achieved, and operation noise is low.

    本发明公开了一种电动平衡重式叉车及其电助力转向系统。转向系统包括方向盘总成、连接于方向盘总成的转向助力器和通过转向传动机构连接于转向助力器的转向桥总成;转向助力器包括助力电机、输入轴、输出轴和连接于输入轴和输出轴之间的扭力杆,输出轴传动连接于助力电机;扭力杆连接有扭力传感器,转向助力器连接有用于检测输入轴转动角度的转向角度传感器,助力电机、转向角度传感器、扭力传感器均通讯连接于转向控制器,转向控制器用于在转向角度传感器检测到输入轴转动到设定极限角度时控制助力电机断电。通过助力电机带动转向桥总成转向,采用电力控制转向替代液压控制,可以避免漏油问题的产生,具有环保效果,运行噪音较小。
