The role of car springs

2022-07-12

Automobile suspension is a general term for all force-transmitting connection devices between the frame of the car and the axle or wheels. Its function is to transmit the force and torque acting between the wheels and the frame, and the buffer is transmitted from the uneven road to the car. The impact force of the frame or body, and the vibration caused by it is attenuated to ensure that the car can run smoothly. A typical suspension structure consists of elastic elements, guide mechanisms and shock absorbers, and individual structures include buffer blocks, stabilizer bars, etc. The elastic elements are in the form of leaf springs, air springs, coil springs and torsion bar springs, while modern car suspensions mostly use coil springs and torsion bar springs, and individual high-end cars use air springs.
Suspension is an important assembly in a car, which elastically links the frame and the wheels, and is related to the various performance of the car. From the outside, the car suspension is only composed of some rods, cylinders and springs, but don't think it is very simple. On the contrary, the car suspension is a car assembly that is difficult to achieve perfect requirements. This is because the suspension has both To meet the comfort requirements of the car, but also to meet the requirements of its handling stability, and these two aspects are opposed to each other. For example, in order to achieve good comfort, the vibration of the car needs to be greatly buffered, so the spring should be designed to be softer, but the softer spring is easy to cause the car to brake "nodding", accelerate "head up" and seriously roll left and right. It is not conducive to the steering of the car, and it is easy to cause the car to be unstable.
