Description

Technical Field

[0001] The utility model belongs to the technical field of automobile components and relates to a steering knuckle, in particular to a radially stable steering knuckle. Background Art

[0002] The car steering knuckle, also known as the "ram's horn", is one of the important parts in the car's steering axle. It can make the car run stably and sensitively transmit the direction of travel. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheels to rotate around the kingpin to steer the car.

[0003] The common steering knuckles on the market are designed by setting a steering knuckle body at the end of the input shaft and connecting the steering knuckle body to transmit power. However, due to the integrated structure, the vibration of the vehicle will be directly transmitted through the steering knuckle. In addition, the steering knuckle structure is complex and is usually fixed by welding. The radial support force is insufficient, and long-term vibration will cause cracks in the weld, affecting safety. Summary of the Invention

[0004] The purpose of the utility model is to provide a shock-absorbing radially stable steering knuckle in response to the above-mentioned problems existing in the prior art.

[0005] The objectives of the utility model can be achieved through the following technical solutions: a radially stable steering knuckle, comprising a steering knuckle body and a steering shaft, wherein an upper fixing portion and a lower fixing portion are respectively provided at the upper and lower ends of the steering knuckle, and wherein the steering shaft is composed of a steering shaft body and a mounting portion, a mounting hole for installing the mounting portion is provided on the steering knuckle body, a plurality of reinforcing protrusions for enhancing radial stability are provided on the upper end of the mounting portion, a plurality of positioning grooves matching the reinforcing protrusions are provided on the steering knuckle body and on the sides relative to the mounting hole, a shock absorbing assembly is provided inside the steering knuckle body and on both sides relative to the positioning groove, a mounting groove for installing the shock absorbing assembly is provided inside the steering knuckle body, and the shock absorbing assembly is composed of a shock absorbing protrusion and a shock absorbing spring.

[0006] In the above-mentioned radially stable steering knuckle, there are three reinforcing protrusions, limiting protrusions are arranged on both sides of the shock-absorbing protrusion, and limiting spaces for the limiting protrusions to move are opened inside the steering knuckle body and relative to both sides of the mounting groove. The shock-absorbing spring is arranged in the limiting space and relative to the lower end of the limiting protrusion.

[0007] Compared with the prior art, the reinforcing protrusions provided in the present invention can increase the radial connection strength between the steering knuckle body and the steering shaft, and the shock-absorbing components provided on both sides of the positioning groove can reduce the radial impact force, increase the radial connection strength and improve safety performance.
