Single-hydraulic-cylinder power-assisted steering drive axle adopting forked type adjusting arms

Abstract

The invention provides a single-hydraulic-cylinder power-assisted steering drive axle adopting forked type adjusting arms. The drive axle is composed of a left wheel edge reducer assembly, a right wheel edge reducer assembly, a left steering knuckle arm, a right steering knuckle arm, a left outer axle shaft, a right outer axle shaft, two double-cross axle universal couplings which are the left double-cross axle universal coupling and the right double-cross axle universal coupling, two inner axle shafts which are the left inner axle shaft and the right inner axle shaft, a differential mechanismassembly, a main reducer assembly, two outer axle housings which are the left outer axle housing and the right outer axle housing, a steering gear assembly, a bracket, a front axle shell, a front axle shell end cover, the two forked type adjusting arms which are the left forked type adjusting arm and the right forked type adjusting arm, a front portion front axle support, a rear portion front axle support and the like. It is guaranteed that the front axle shell can automatically adapt to the working conditions such as an irregular road condition and a slope, it is guaranteed that the attitudeof a vehicle body is self-leveled, the contact area between tires and the ground is increased, and the stability of the vehicle body is kept; and the drive axle is high in structural strength and rigidity, scientific in design and good in manufacturability and has the application and popularization value.

Description

1. Technical field [0001] The invention relates to a single-hydraulic-cylinder power-assisted steering drive axle adopting a fork-shaped adjustment arm, in particular to a steering drive axle with self-levelling body attitude, which belongs to the technical field of vehicle steering axles. 2. Background technology [0002] Hilly and mountainous areas are mostly dominated by irregular ground, slopes and other ground. When traditional tractors are transferred in hilly areas and farmland operations, the terrain and ground-induced changes in tractor attitude are complex and changeable. The driving stability of the unit is poor, and the safety of the driver is difficult to guarantee. Therefore, in order to ensure the adaptability of the tractor in the mountains and realize the self-leveling of the tractor body on the slope, a new type of steering axle is needed, which can automatically adapt to the road surface and can cooperate with the attitude active leveling device and the run...

AI Technical Summary

Problems solved by technology

[0005] However, the existing tractor steering axle cannot ensure that each tire is in full contact with the ground while adapting to the ground, nor can it ensure that the vehicle body is always in a horizontal state, which may easily lead to safety hazards such as poor stability and easy rollover.
