The increase in car ownership is evident to all, especially with the emergence of the younger generation of consumers, injecting new vitality into the automotive market. So in order to cater to the demand of young people for cars, almost all car brands are vigorously promoting the handling performance of their products, and even adding more and more sports elements. However, in the process of buying a car, people often focus on price, configuration, power, and appearance. In fact, the suspension system of the car has the greatest impact on the handling performance of the car.
The suspension system of a car is divided into independent suspension and non independent suspension, each with its own advantages and disadvantages. In order to better utilize the characteristics of the suspension and overcome its shortcomings, people have added some special connecting rods to the suspension, such as the stabilizer bar, Watt link, Panhard link, etc. Today we will talk about the structure and function of the lateral stabilizer bar.
The lateral stabilizer bar, also known as the anti roll bar, is an auxiliary elastic component in automotive suspension. The lateral stabilizer bar is a torsion bar spring made of spring steel, which is shaped like a "U" and is horizontally placed at the front and rear ends of the car. The middle of the pole body is hinged to the frame with a sleeve, and the two ends of the pole are fixed to the lower arms of the left and right suspensions.
When a car is cornering, the centrifugal force can cause the body to roll, causing the inner wheel suspension to stretch and the outer wheel suspension to compress, causing the anti roll bar to twist and produce a large amount of torque, which acts in the opposite direction on the suspension, preventing excessive lateral tilting of the body during turns and improving driving smoothness.
The anti roll bar only hardens the suspension when it is in operation, unlike hard springs that completely harden the suspension. If we want to rely solely on springs to reduce body roll, we may need very hard springs, and we need to use shock absorbers with high damping coefficients to suppress spring bouncing. In this way, we must bear the aftermath of poor comfort caused by hard springs and shock absorbers. But if combined with appropriate anti roll bars, it can not only reduce roll, but also avoid sacrificing the necessary comfort and tracking. Therefore, the combination of anti roll bars and springs is the most feasible way to achieve a compromise between comfort and handling.
Generally, independent suspension systems are equipped with a stabilizer bar, and a small number of torsion beam suspensions also have a stabilizer bar installed. For example, most French cars have rear torsion beam suspensions equipped with lateral stabilizer bars. It is said that the good chassis tuning of the car is closely related to this.
