Problems solved by technology

[0004] The present invention mainly solves the technical problem that the rigidity of the anti-stabilizer bar of the formula car in the prior art cannot be adjusted, and it is necessary to pay great attention to the speed change on different curves to prevent it from rolling over, which will have a great impact on the performance of the car. Provides a stabilizer bar that enables instant stiffness adjustments while the vehicle is in motion

Abstract

The invention relates to a real-time adjustment system for the stabilizer bar of a formula racing car, which comprises a stabilizer bar, two rocker arms, and two tie rods. connected, the tie rod is connected with the wheel suspension, and it is characterized in that the rocker arm is slidably connected with the pull rod, and the two pull rods are connected through a cross bar, and one of the pull rods or the cross bar is connected with a long pull rod. The pull rod is connected with a driving device that can drive it to move axially. The present invention is a transverse stabilizer bar capable of real-time rigidity adjustment during vehicle running, so as to realize its adaptation to different curves, thereby achieving the effect of improving racing performance.

Description

technical field [0001] The invention relates to a formula racing car, in particular to a lateral stabilizer bar of a formula racing car. Background technique [0002] The stabilizer bar is an auxiliary elastic element in the car suspension. Its function is to prevent the body from excessive lateral roll when turning, and try to keep the body as balanced as possible. The purpose is to reduce the degree of lateral roll of the car and improve ride comfort. Stabilizer bars are torsion bar springs made of spring steel that run across the front and rear of the car. The middle part of the rod body is hinged to the vehicle frame with a stabilizer rod bushing, and the two ends of the rod are respectively fixed on the left and right suspensions. When the body only moves vertically, the suspension on both sides deforms the same, and the stabilizer bar does not work. When the car turns, the body rolls, the suspension on both sides jumps inconsistently, the outer suspension will pres...
