Forklift steering method and device and forklift

Abstract

The invention provides a forklift steering method and device and a forklift. The forklift steering method comprises the following steps: obtaining the deflection angle of a steering wheel; based on the deflection angle, determining the differential ratio of the left driving wheel to the right driving wheel; determining a target rotating speed based on the trigger signal of the accelerator pedal; and outputting the rotating speed of the left driving wheel and the rotating speed of the right driving wheel based on the target rotating speed and the differential ratio. According to the forklift steering method and device and the forklift, the differential ratio of the left driving wheel and the right driving wheel is determined according to the deflection angle of the steering wheel, the rotating speed of the left driving wheel and the rotating speed of the right driving wheel are output according to the target rotating speed and the differential ratio, in this way, the driving wheels and the steering wheel can rotate cooperatively, flexible rotation in a small-range space is achieved, in-situ rotation can be achieved, steering control is simpler and more convenient through an electric control mode, and steering precision and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of working machinery, in particular to a steering method and device for a forklift and a forklift. Background technique [0002] Forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. Forklifts are mainly used for cargo handling in factories. Since the work tasks of forklifts are mainly in the factory area and need to be moved between multiple locations, forklifts are required to be able to achieve more flexible steering. [0003] The current forklifts usually give the steering direction by the steering wheel, and the driving wheel follows the steering wheel to change the direction of rotation. Such a solution cannot realize steering in a small range, cannot realize in-situ steering, and the steering control is complicated, and the steering The precision is lower. Contents of t...
