Chassis suspension (also known as suspension) is an important component of a car, referring to all the power transmission connection devices between the frame and the axle or wheels.
The main function of chassis suspension includes transmitting various forces and moments between the wheels and the vehicle body, such as support, braking, and driving forces, while buffering the impact of uneven road surfaces on the vehicle body, ensuring ride comfort and driving stability, and reducing the dynamic load on goods and the vehicle itself.
A typical car suspension structure consists of elastic components, shock absorbers, and guiding mechanisms, which respectively play a role in buffering, damping, and force transmission. The vast majority of suspensions have spiral spring and shock absorber structures, and different types of suspensions have significant differences in their guiding mechanisms, which is also the core part of the differences in suspension performance. According to different structures, suspension can be divided into two types: non independent suspension and independent suspension.
