The invention discloses an electric piling car electric power steering device which comprises a control handle, a power steering gear, a controller, a transmission mechanism, a walking driving device and a steering wheel, wherein an input shaft is arranged at the upper end of the power steering gear, an output shaft is arranged at the lower end of the power steering gear, the lower end of the control handle is connected with the input shaft, and the output shaft of the power steering gear is connected with the transmission mechanism; the transmission mechanism is connected with the walking driving device, and the walking driving device can drive the steering wheels to walk. When the power steering gear is powered on and works normally, an operator rotates the control handle to control the input shaft to rotate, and at the moment, the torque of the output shaft can be increased through the power effect of the power steering gear to drive the walking driving device to rotate so as to drive the steering wheel to steer; when the power steering gear loses the power effect due to failure power failure, the mechanical transmission device in the power steering gear can equivalently transmit torque to the output shaft, at the moment, steering is equivalent to manual steering, and the situation of steering failure can be avoided.

    本发明公开了一种电动堆垛车电助力转向装置,包括:操控手柄、助力转向器、控制器、传动机构、行走驱动装置和转向轮,其中助力转向器的上端设有输入轴,下端设有输出轴,操控手柄的下端与输入轴连接,助力转向器的输出轴与传动机构连接;传动机构与行走驱动装置连接,行走驱动装置可以驱动转向轮行走。当助力转向器通电正常工作时,操作者转动操控手柄,以控制输入轴转动,此时通过助力转向器的助力作用,可增大输出轴的扭矩,以带动行走驱动装置转动,进而带动转向轮转向;当助力转向器因故障断电失去助力作用时,助力转向器内部的机械传动装置可以将扭矩等量地传递到输出轴,此时相当于人力转向,可避免转向失效的情况出现。
