Description

A FSAE racing lateral stabilizer

technical field

The invention relates to the field of machinery, in particular to the field of small formula car manufacturing, in particular to a lateral stabilizer mechanism of an FSAE car.

Background technique

With the vigorous development of the automobile industry, people pay more and more attention to the handling stability and smoothness of the automobile. As an important part of the automobile suspension, the stabilizer bar is an auxiliary elastic element in the automobile suspension. The main function is to prevent the body from excessive lateral roll during cornering. The purpose is to prevent the lateral rollover of the car and improve the ride comfort of the car. The stabilizer bar is a torsion bar spring made of spring steel, in the shape of "U" and "Z", which is placed horizontally or vertically at the front and rear of the car. The middle part of the rod body is hinged or welded with the frame through a specific structure, and the two ends of the rod are respectively fixed on the left and right suspensions. When the body only moves vertically, the deformation of the suspension on both sides is the same, and the lateral stabilizer bar does not work. When the body rolls, the suspension on both sides jumps inconsistently, and the stabilizer bar will twist. Most modern racing cars are equipped with lateral stabilizers.

At present, in the case of ensuring that the lateral stabilizer achieves a series of performance indicators, the design difficulties are mainly in the aspects of inconvenient layout, difficult adjustment of stiffness, high cost, and incompatibility with light weight. Therefore, the present invention makes the following improvements to the existing lateral stabilizer mechanism.

SUMMARY OF THE INVENTION

In view of the above situation, the technical problems to be solved by the present invention are: when the existing lateral stabilizer adjusts the stiffness, it is inconvenient to move the stabilizer bar to adjust, and the lightweight design is improved; the stabilizer bar is mostly subjected to bending force, and the rigidity that can be provided is small; and It has a complex structure and occupies a large space, which is easy to cause unnecessary interference problems.

In order to solve the above-mentioned technical problems, the technical scheme adopted in the present invention is to provide a FSAE racing lateral stabilizer, the structure of which includes: a rod end radial joint bearing, a nut, a push-pull rod bonding sleeve, a push-pull rod, a plug bolt, Stabilizer bar segment arm, adjustment hole, stabilizer bar and bolt and nut; wherein, there are two holes at both ends of the stabilizer bar, which are connected with a stabilizer bar segment arm through two bolts and nuts, and the two stabilizer bar segment arms are distributed up and down At the same time, the stabilizing rod segment arm and the push-pull rod are connected by plugging bolts and nuts, and the other end of the push-pull rod is connected with the nut and the rod end radial joint bearing through the push-pull rod bonding sleeve.

The stabilizing rod segment arm structure is provided with 5 adjustment holes, and the stabilizing rod segment arm can change the length of the torsion arm of the stabilizing rod through the adjusting holes, thereby changing the rigidity of the stabilizer.

During use, the stabilizer bar is supported and fixed by the bearing and the bearing seat.

The beneficial effects of the present invention are as follows: the stress condition of the stabilizer bar is improved, greater rigidity can be provided, and light weight is also improved; the mechanism occupies very little space and avoids unnecessary interference problems.
