Suspension system, engine and gearbox are also called the three most important assemblies of automobiles. The suspension system is a part that connects the wheels and the car body with springs and shock absorbers, mainly to absorb the bumps transmitted from the ground to the car. The design and adjustment of its structure is related to the handling performance, sports performance and comfort performance of the vehicle when driving.
Automobile rear suspension system is generally divided into dependent suspension and independent suspension. The wheels of dependent suspension are installed at both ends of an integral axle. When one wheel jumps, the other wheel also jumps accordingly, making the whole body vibrate or tilt.
The independent suspension axle is divided into two sections, and each wheel is independently installed under the frame through a coil spring. When one wheel jumps, the other wheel is not affected, and the wheels on both sides can move independently, which improves the stability and comfort of the car.
Extended data
There are three common dependent suspension systems: parallel leaf spring suspension, torsion beam suspension and torsion beam suspension.
superiority
1, when bouncing, the left and right wheels will be involved with each other, and a small change in tire angle will make the tire wear less.
2. It is not easy to change the angle of the wheel when the height of the car body is reduced, so that the handling feeling is consistent.
3. Simple structure, low manufacturing cost and easy maintenance.
4. The occupied space is small, which can reduce the height of the vehicle floor.
disadvantaged
1, when the left and right wheels bounce, they will get involved with each other, which will reduce the ride comfort and control stability.
2. Because of its simple structure, small design freedom and poor control stability.
