What is Suspension System?

Suspension system is a general term for all force-transmitting connecting devices between the frame of the car and the axle or wheels. The impact force of the body and the vibration caused by it are attenuated to ensure the smooth running of the car.

Generally speaking, the suspension system of a car is divided into two types: non-independent suspension and independent suspension. The wheels of non-independent suspension are installed at both ends of an integral axle. When one wheel jumps, the other wheel jumps accordingly, so that the whole The body vibrates or tilts; the independently suspended axle is divided into two sections, and each wheel is independently installed under the frame by a coil spring. When one wheel jumps, the other wheel is not affected, and the wheels on both sides can move independently, improving the car stability and comfort. Due to people's higher and higher requirements for the ride comfort and handling stability of the car, the non-independent suspension system has been gradually eliminated. Because the space under the body makes the car appear to be suspended in mid-air, how to combine the body that seems to be suspended in mid-air with the wheels touching the ground? This combined device is the suspension system. In addition to supporting the weight of the vehicle body, the suspension system is also responsible for reducing the vibration during driving and the handling performance of the vehicle. Suspension system How does the suspension system magically function to reduce vibration while driving and maintain the handling performance of the vehicle? The original suspension system also includes shock absorbers, springs, anti-roll bars, connecting rods and other parts. Between the wheels and the car body, the so-called suspension system is responsible for carrying the car body and absorbing vibrations, providing the best ride comfort.
