Front drive axle with large steering angle

Abstract

The invention discloses a front drive axle with a large steering angle, which comprises a front axle shell, wherein the front axle shell is integrally formed, two steering knuckle shells which are symmetrically distributed are fixedly arranged at two ends of the front axle shell, the inner rotation angle of a front wheel of the front axle shell is more than 50 degrees, the inner corner of the front wheel is the angle at which the trapezoidal arm in the steering trapezoid rotates when the front end of the front wheel deflects to the outer side of the drive axle to the maximum angle, the outer corner of the front wheel of the front axle shell is more than 40 degrees, the outer corner of the front wheel is the angle at which the front end of the front wheel deflects to the inner side of the drive axle to the maximum angle. The angle of rotation of the trapezoidal arm in the steering trapezoid is increased, so that the dead point in the steering process is eliminated by increasing the steering angle, the number of left and right steering turns of the steering wheel is consistent, the operability is improved, when the front drive axle is in a working state, when the driving oil rod is used for steering, when the vehicle turns, the tension spring is compressed under the action of impact force, thereby playing a role in buffering the driving oil rod and improving the stability of thedriving oil rod.

Description

technical field [0001] The invention relates to a large range, in particular to a front drive axle with a large steering angle. Background technique [0002] The existing tractor front drive axle mainly consists of a front axle housing, a steering knuckle connected to both ends of the front axle housing, a steering tie rod and a side single oil cylinder. Because the front drive axle is equipped with a tie rod, the steering force of the side-mounted single cylinder is small and the operability is poor. 50°, the turning radius of the whole machine is large and inflexible when the whole machine is working. At the same time, it is not easy to add lubricating oil in the steering knuckle housing of the existing tractor front drive axle, which leads to excessive wear in the steering knuckle housing; when the front drive axle is in working condition , due to the use of the driving oil rod for steering, the driving oil rod is subjected to internal stress when the vehicle is turned, ...

Problems solved by technology

Because the front drive axle is equipped with a tie rod, the steering force of the side-mounted single cylinder is small and the operability is poor. 50°, the turning radius of the whole machine is large and inflexible when the whole machine is working. At the same time, it is not easy to add lubricating oil in the steering knuckle housing of the existing tractor front drive axle, which leads to excessive wear in the steering knuckle housing; when the front drive axle is in working condition , due to the use of the driving oil rod for steering, the driving oil rod is subject to internal stress when turning through the vehicle, which causes certain damage to the driving oil rod
