Steering drive axle of normal ground clearance

Abstract

The invention discloses a steering drive axle of a normal ground clearance, which comprises a front axle shell body, wherein the middle part of the front axle shell body is hinged with a front axle bracket and a holder through a rocking axle; both ends of the front axle shell body are connected with a tail shell body, and the outside of the tail shell body is hinged with steering joints; a hinging pull rod is arranged between the tail shell bodies at both sides and the holder, and a cross pull rod is hinged between steering joints at both sides; a main reducing gear, a differential mechanism assembly and two inner half axles connected to the differential mechanism assembly are installed in the front axle shell body, two inner half axles are connected to outside half axles at both sides through the universal joint. The steering drive axle has the advantages that the angle between the wheel and the front axle shell body can be changed along with the road condition such as irregular pavement or slope, thus the wheel can be self-leveled by matching with the car gesture in a big slope, and the contact face between the tire and the ground is increased, the safety and stability for driving and working are enhanced. Moreover, the axle is a drive axle, and can guarantee the big driving force of the vehicle, overcome obstacle and prevent slippage.

Description

technical field [0001] The invention relates to a vehicle steering axle, in particular to a normal clearance steering drive axle. Background technique [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 running mechanism to level the body. [0003] The land in hilly and mountainous areas is usually uneven, and each tire cannot fully contact the ground when the tractor...

Problems solved by technology

[0005] However, the existing tractor front axle cannot ensure that each tire is in full contact with the ground while adapting to the ground, which may easily lead to safety hazards such as poor stability and easy rollover.
