Novel front axle steering knuckle assembly device

Abstract

The invention relates to a novel front axle steering knuckle assembly device. The front axle steering knuckle assembly device comprises a steering knuckle, a steering knuckle frame, a needle roller bearing structure and a steering knuckle thrust bearing, wherein the steering knuckle frame is connected to one end of the steering knuckle; a steering knuckle sleeve is connected to the other end of the steering knuckle; the needle roller bearing structure and the steering knuckle thrust bearing are arranged between the steering knuckle and the steering knuckle frame; and the steering knuckle is in rolling connection with the steering knuckle frame. According to the novel front axle steering knuckle assembly device disclosed by the invention, the installation problem of pneumatic braking components is solved, and a steering knuckle main pin and the steering knuckle frame of the newly designed steering knuckle assembly are connected through the needle roller bearing, and sliding lubricationof the steering part is changed into rolling lubrication so as to reduce the vehicle steering force, therefore the vehicle has the advantage of lightness for steering.

Description

technical field [0001] The invention relates to a novel front axle steering knuckle assembly device. Background technique [0002] The steering knuckle assembly is one of the main parts on the steering axle of the car. The function of the steering knuckle is to bear the front load of the car, support and drive the front wheel pin to turn to make the car turn. Shock loads require high strength. [0003] The structure of the steering knuckle assembly widely used in the steering drive wheel of the front axle of heavy-duty off-road vehicles is as follows: figure 1 , figure 2 , image 3 As shown, the boss holes 2 and 3 extending up and down from the steering knuckle 1 are axially aligned to receive a kingpin 4 and 5 of the steering knuckle, and the upper and lower kingpins 4 and 5 of the steering knuckle are connected to the boss hole by welding In 2 and 3, the steering knuckle sleeve 6 is connected to the steering knuckle 1 through the bolt 7 . The steering knuckle bracke...

AI Technical Summary

Problems solved by technology

[0004] In this kind of steering knuckle assembly, the steering knuckle sleeve is connected to the steering knuckle by bolts, and the steering knuckle kingpin is connected to the steering knuckle by welding, resulting in complex structure, high machining accuracy, large number of parts, low strength, and low steering. The bushing structure used in the connecting structure between the knuckle king pin and the steering knuckle bracket, the bushing is in a state of sliding friction during the movement of the car, and the wear is serious, so it needs to be repaired and replaced irregularly

The steering knuckle bracket with fan-shaped structure takes up a lot of space, and the space is even narrower when the front axle adopts oil-air suspension structure, and can only be used on the brake hub of oil brake, so this steering knuckle assembly is used for air brake. After the front axle turns to the drive wheels, a new steering knuckle assembly structure needs to be designed
