Double-hydraulic-cylinder power-assisted steering drive axle adopting lower-arranged adjusting arms

Abstract

The invention discloses a double-hydraulic-cylinder power-assisted steering drive axle adopting lower-arranged adjusting arms. The double-hydraulic-cylinder power-assisted steering drive axle is composed of a left wheel side reducer assembly, a right wheel side reducer assembly, a left steering knuckle arm, a right steering knuckle arm, a left outer axle housing, a right outer axle housing, a bracket, a front axle shell, a rear portion front axle support, a steering tie rod, a left adjusting arm, a right adjusting arm, a left steering gear assembly, a right steering gear assembly, a left hingepin, a right hinge pin, a front portion front axle support, a front axle shell end cover, a main reducer assembly, a left outer half-axle, a right outer half-axle, a left double-cross axle universalcoupling, a right double-cross axle universal coupling, a left inner half-axle, a right inner half-axle and a differential mechanism assembly. The double-hydraulic-cylinder power-assisted steering drive axle adopting the lower-arranged adjusting arms can guarantee that the front axle shell can automatically adapt to irregular road conditions or slope conditions and guarantees self-leveling of a car body posture; the contact area between tires and the ground is enhanced, it is ensured that a car body maintains stable, and the ability to adapt to the road conditions and slope is achieved; and the structure design is scientific, manufacturability is good, and the value of popularization and application is achieved.

Description

1. Technical field [0001] The invention relates to a dual-hydraulic-cylinder power-assisted steering drive axle adopting a lower-mounted adjustment arm, in particular to a steering drive axle with a self-leveling 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 ru...

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.
