Abstract

The invention belongs to the field of steering drive bridges, and particularly relates to a steering drive axle, an automatic guided vehicle and a control method based on the steering drive axle. Theusing method comprises the following steps that the steering drive axle is mounted on the guided vehicle, the extension or shortening of steering oil cylinders on the steering drive axle is controlledby adopting a distal hydraulic control system, corresponding steering knuckle arms are pulled to move, and then corresponding steering knuckles are pulled to rotate, and the automatic steering function of the guided vehicle is realized. According to the steering drive axle, two sets of steering oil cylinders is used, a first steering oil cylinder drives a first steering knuckle to rotate, and a second steering oil cylinder drives a second steering knuckle to rotate; when the two steering oil cylinders work, the motion is carried out according to the given extension or shortening amount by thehydraulic control system, and the two steering oil cylinders do not interfere with each other; and the running accuracy caused by installation errors and wear of the first half shaft / second half shaft has no effect on the second half shaft / first half shaft.

Description

technical field [0001] The invention belongs to the field of steering drive axles, and in particular relates to a steering drive axle, an automatic guided vehicle and a control method based on the steering drive axle. Background technique [0002] Automatic guided vehicles are widely used in warehousing, logistics and other industries. Compared with traditional transfer tools such as forklifts, automatic guided vehicles have realized automatic operation and high work efficiency, and have gradually become an indispensable part of modern enterprises. The steering system is one of the key systems on the automatic guided vehicle, and the reliability of the steering system directly affects the working performance of the automatic guided vehicle. When the automatic guided vehicle turns, it should respond quickly, the steering angle can be controlled, the steering speed can be controlled, and the steering should be stable. At present, the steering system of automatic guided vehic...
