Description

Two-wheel drive rear steering knuckle

technical field

The utility model relates to a steering knuckle used on an automobile drive axle, in particular to a rear steering knuckle for a two-wheel drive vehicle.

Background technique

The steering knuckle is one of the main parts of the car suspension, which can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to bear the load of the car. When the car is running, it bears variable impacts Load, therefore, requires it to have high strength.

At present, most steering knuckles on the market are made of iron or forged steel, which have defects such as heavy weight, high energy consumption, and unreasonable structural design, which seriously affect the handling, comfort performance and service life of the vehicle. With the continuous improvement of automobile performance, the rigidity and strength requirements of steering knuckles are also getting higher and higher. The structure design of most steering knuckles in the existing market is complex and unreasonable, and most of them are not suitable for the structural performance requirements of high-end automobiles.

Therefore, there is an urgent need for a steering knuckle with light weight and optimized structure.

Contents of the invention

The purpose of the utility model is to solve the shortcomings of the above-mentioned prior art, and provide a rear steering knuckle of a two-wheel drive vehicle with a scientific and reasonable structural design, which can meet the rigidity and strength requirements of high-performance vehicles.

The utility model is achieved through the following technical solutions:

The rear steering knuckle of a two-wheel drive vehicle includes an aluminum steering knuckle body 1 with an integrally formed structure. The special feature is that the steering knuckle body 1 has a hub mounting part, and the hub mounting part The hub bearing positioning hole 2 in the middle of 1, and three hub bolt connection holes 3 set around the outer circumference of the hub bearing positioning hole 2 are formed. Blind holes on the mounting surface, on the other side opposite to the main mounting surface of the hub, the upper control arm connecting part, the rear tie rod connecting part, the lower control arm connecting part, the brake caliper installing part and the trailing arm connecting part respectively extend. Wherein, the upper control arm connection part and the rear tie rod connection part are the upper control arm connection hole 8 and the rear tie rod connection hole 4 extending upward along the steering knuckle body 1, and the lower control arm connection part is the extension direction The lower control arm connection hole 5 opposite to the upper control arm connection hole 8 and the rear tie rod connection hole 4; the trailing arm installation part is two extending out of the trailing arm connection hole 6, and the brake caliper installation part is Two brake caliper positioning holes 7 are opened on the steering knuckle body 1, one of which is located between the connecting hole 8 of the upper control arm and the connecting hole 6 of the trailing arm, and the other hole is located between the connecting hole 8 of the upper control arm and the connecting hole 6 of the trailing arm. The inner side of the middle part of the arm connection hole 6.

The central axis of the upper control arm connecting hole 8, the rear tie rod connecting hole 4 and the lower control arm connecting hole 5 and the central axis of the hub bearing positioning hole 2 are perpendicular to each other in space;

The central axes of the two trailing arm connection holes 6, the brake caliper positioning hole 7 and the hub bearing positioning hole 2 are parallel to each other in space;

One side of the steering knuckle main body 1 is provided with an ABS sensor installation hole 9 .

The rear steering knuckle of the two-wheel drive vehicle of the utility model is integrally formed by aluminum water molding, and the overall weight is reduced. At the same time, the effective structure optimization of each connecting part of the steering knuckle is carried out, unnecessary materials are reduced, the effect of weight reduction and energy saving is outstanding, and the performance is more stable. .
