Abstract

The invention discloses an electric fork-lift truck steering device which comprises a steering wheel, a steering column, a cardan joint, a steering actuating device, a carframe and a shift wheel, wherein the steering column is arranged below the steering wheel and is connected with the steering wheel. The cardan joint is arranged below the steering column and is connected with the steering column. The steering actuating device is connected with the cardan joint. The carframe is connected with the steering actuating device. The shift wheel is arranged on the carframe. The steering actuating device comprises a chain wheel mechanism and the steering wheel, wherein the horizontally arranged steering is connected with the cardan joint through the chain whell mechanism. The carframe comprises a vertical part and a horizontal part, wherein the horizontal part is connected with the bottom end of the vertical part. The top end of the vertical part of the carframe is fixedly connected with the end face of the steering wheel. The horizontal part of the carframe is provided with the shift wheel. The electric fork-lift truck steering device has the advantages of being simple in structure, convenient to operate and low in cost. In the process of steering, a driver can adjust angles of the shift wheel by constantly steering the steering wheel according to factors such as road surface bending changes and speed changes to maintain steering tracks which a driver wants to reach, and therefore the electric fork-lift truck steering device is reliable in steering, and low in stoppage rate and the like.

Description

[0001] technical field [0002] The invention relates to a steering device of an electric vehicle, in particular to a steering device of an electric forklift. Background technique [0003] When the usual mechanical steering system needs to turn, the driver applies a steering torque to the steering wheel, and the torque is input into the steering gear through the steering shaft. The steering gear as a reduction transmission device has a reduction transmission pair, and the force amplified by the steering gear and The decelerated movement is transmitted to the steering tie rod, and then transmitted to the steering knuckle arm fixed on the steering knuckle, which deflects the steering knuckle and the steering wheels supported by it, thereby changing the driving direction. The mechanism is complicated, the cost is unsatisfactory, and the layout of the whole vehicle is poorly optimized. Contents of the invention [0004] The technical problem to be solved by the present invent...
