Steering support assembly of an electric steering electric tractor

Abstract

The invention provides an electric steering power-driven traction trolley steering support assembly. The electric steering power-driven traction trolley steering support assembly comprises a steering column, a bearing base and a support installation plate fixedly connected to the bearing base; a steering arm installation base is coaxially connected to the upper end of the steering column, a pair of corner stopping blocks are symmetrically arranged on the circumferential lateral wall of the steering arm installation base, and a step cylinder used for fixing the output end of a corner potentiometer is arranged at the lower end of the steering column; a protruding ring is arranged in the bearing base in the circumferential direction, an upper bearing and a lower bearing are arranged at the upper end and the lower end of the protruding ring respectively, a damping ring is arranged between the upper bearing and the lower bearing, and the steering column is sequentially sleeved with the upper bearing, the damping ring and the lower bearing; a corner limiting block is arranged on the top face of the support installation plate, and a connecting piece for fixing a support of the corner potentiometer is arranged on the bottom face of the support installation plate. According to the electric steering power-driven traction trolley steering support assembly, the force of friction of the damping ring and the steering column is changed by adjusting the compression force of a fastening bolt on the damping ring, the gyroscopic moment of the steering column is accordingly changed, operation is convenient, and the abrasion strength is lower.

Description

Technical field [0001] The invention relates to the technical field of electric tractors, and in particular to a steering support assembly for electric steering electric tractors, mainly to provide light, flexible and reliable steering force for electric steering electric tractors. This support assembly It can also be used on various electric steering storage vehicles, such as electric stackers, electric pallet trucks, etc. Background technique [0002] Electric tractors have a large steering force, and the operator is prone to fatigue after long-term use. Therefore, the tractor is equipped with electric steering, and an angle signal is given to the angle potentiometer. The controller controls the steering motor to rotate the corresponding number of turns to drive the whole vehicle to turn. The turning torque required by the angle potentiometer is very small, and the steering is too sensitive, resulting in frequent operation of the steering motor, which not only consumes battery ...
