Steering system of full-electric piling car

Abstract

The invention discloses a steering system of a full-electric piling car. The steering system comprises an operation rudder, an operation connecting rod, a tiller seat, a steering shaft, a driving wheel, an upper shaft sleeve and a lower shaft sleeve. The lower end of the steering shaft is in shaft connection with the driving wheel, and the upper end of the steering shaft is in locked connection with the tiller seat; the operation rudder is fixed to the tiller seat through the operation connecting rod which is arranged in an inclining manner, and the included angle between the operation connecting rod and the horizontal plane ranges from 30 degrees to 60 degrees; handles allowing the left hand and the right hand to be held are arranged on the operation rudder; basic control buttons are arranged on the handles; the upper portion and the lower portion of the steering shaft are fixed to a rack through the upper shaft sleeve and the lower shaft sleeve respectively; an upper needle bearing is arranged between the steering shaft and the upper shaft sleeve; and a vibration reduction spring which is arranged on the steering shaft in a sleeving manner is arranged on the lower side of the upper shaft sleeve, and a lower needle bearing is arranged between the lower shaft sleeve and the steering shaft. The steering system has the advantages of being simple in structure, convenient to manufacture, reliable in motion, easy in steering, high in generality and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of an all-electric vehicle steering system, in particular to an all-electric stacker vehicle steering system. Background technique [0002] 1. At present, the old-fashioned steering system adopts spline steering, and the processing of splines and spline sleeves is relatively difficult, so it is relatively difficult to assemble and disassemble. [0003] 2. The old-fashioned steering uses deep groove ball bearings as the force receiving and transmitting parts. In order to facilitate floating, a large clearance fit is usually used, so there is a possibility of impact force when walking forward and backward. [0004] 3. The old-fashioned steering usually uses a nylon sleeve to fix the axis. Nylon sleeve is processed by bar material, which has a large loss, and it will deform and increase steering resistance when encountering a large load. Special customization is required for replacement of non-standard parts...

Problems solved by technology

[0005] 4. The installation position of the damping spring of the old-fashioned steering system is fixed

If the driving force needs to be changed, spacers need to be added, and the operability is not strong
