Steering pair assembly and vehicle with steering pair assembly

Abstract

The invention relates to a steering pair assembly. The steering pair assembly includes a left steering pair assembly and a right steering pair assembly. The steering pair assembly includes a left steering knuckle, a front axle, a first main pin, a top-left roller pin bushing, a top-left cover plate, a bottom-left roller pin bushing, a first snap spring, a thrust gasket, a bottom-left cover plate and a first wedge-shaped lock pin. The right vice steering assembly includes a right steering knuckle, a front axle, a second main pin, a top right roller pin bushing, a top-right cover plate, a cylindrical roller thrust bearing, a bottom-right roller pin bushing, a second snap spring, a bottom-right cover plate and a second wedge-shaped lock pin. According to the structure of the steering pair assembly on the steering front axle, by changing the structure of the steering pair neck bush, the friction force during the rotation of the steering pair is reduced, the aligning torque of the vehicle during travelling is improved, and the vehicle easily goes straight. The influence of the road on a steering system is reduced by reducing the inner distance and the inner inclination of the main pins, then the stability of the vehicle driving is improved, and meanwhile the easiness of rotating a steering wheel during steering is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile front steering, in particular to a steering sub-assembly and an automobile thereof. Background technique [0002] The steering front axle of a commercial vehicle is a non-disconnected steering driven axle, and the structure of the steering front axle is very complicated, such as figure 1 As shown, it is the prior art steering front axle and related parts, including hub 01, steering knuckle 02, upper bushing 03, adjusting gasket 04, wedge lock pin 05, kingpin 06, steering trapezoidal arm 07, steering knuckle arm 08. Front axle 09, leaf spring 010, steering tie rod 011, ball pin 012, lower bushing 013, thrust bearing 014, inner bearing 015 and outer bearing 016. The wedge-shaped lock pin with bolts fixes the kingpin in the kingpin hole of the fist of the front axle so that it cannot rotate. The steering knuckle uses the kingpin to hinge with the front axle to form a steering pair, and supports t...

AI Technical Summary

Problems solved by technology

[0011] Both the upper bush and the lower bush are copper bushes. When the steering knuckle and the kingpin move relative to each other, the sliding friction force is relatively large, which reduces the torque of the car; the inner offset of the kingpin is large, the rotational torque is large, and the rotation is poor; If the inner offset of the kingpin is large, the impact on the steering wheel will be large, and the stability will be poor when driving in a straight line; the copper bush will wear out quickly
