Suspension refers to all the force-transmitting connection devices between the car frame and the axle or wheels. Below is relevant information about suspension: 1. The main functions of the suspension are to transmit all forces and moments acting between the wheels and the body, such as supporting force, braking force, and driving force, while also cushioning the impact loads transmitted from uneven road surfaces to the body, dampening the resulting vibrations, ensuring passenger comfort, and reducing the dynamic loads on cargo and the vehicle itself. 2. A typical car suspension structure consists of elastic elements, shock absorbers, and guiding mechanisms. These three components respectively serve to buffer, dampen vibrations, and transmit forces. Most suspensions feature coil springs and shock absorber structures, but the guiding mechanisms vary significantly among different types of suspensions, which is the core component determining suspension performance differences. Based on structure, suspensions can be categorized into non-independent suspensions and independent suspensions.
