Bushing, automobile steering knuckle and automobile

Abstract

The invention provides a bushing, an automobile steering knuckle and an automobile. The bushing is used for being press mounted in a bushing hole of the automobile steering knuckle. The bushing comprises a columnar body, an inserting end used for inserting towards the bushing hole is arranged on the columnar body in the radial direction, and the end part facing the bushing hole of the inserting end is of a fillet structure. According to the bushing, because the end part facing the bushing hole of the inserting end is of the fillet structure, the inserting end is round and smooth and is not sharp-pointed any more, aluminum scraps are not likely to be scrapped out of a steering knuckle body, after the bushing is press mounted in the bushing hole of the steering knuckle, press-out force of the bushing is increased, the bushing is not likely to be pressed out from the bushing hole of the steering knuckle, the steering knuckle with the bushing assembled conforms to the design requirement, the product qualification ration is increased, and the bushing is capable of playing better shock absorbing, buffering, strength increasing and locating roles in the steering knuckle.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a bushing, an automobile steering knuckle and an automobile. Background technique [0002] Steering Knuckle, also known as "claw horn", is one of the important parts in the steering axle of a car, which can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to turn the car. When the car is running, it bears variable impact loads, so it is required to have high strength. [0003] Automobile steering knuckle bushing is a key component assembled in the bushing hole of the steering knuckle. Lead to poor positioning of the steering knuckle, which in turn leads to the precision of steering when the vehicle is driving. [0004] At present, during the press-fitting process of the steering knuckle and the bushing...

AI Technical Summary

Problems solved by technology

[0005] The problem solved by the invention is that in the prior art, the end structure of the bush used to insert into the bush hole is relatively sharp, and during the process of pressing the bush into the bush hole of the steering knuckle, a large amount of aluminum is easily scraped out of the steering knuckle body. Chips, resulting in a small extrusion force of the bushing, the steering knuckle does not meet the design requirements, and the failure rate of steering knuckle products increases
