The automotive suspension system typically consists of 8 to 12 core components, with the exact number depending on the suspension type and vehicle design. As core components, elastic elements commonly take the form of coil springs, torsion bar springs, or air springs used in high-end models; they work in conjunction with shock absorbers to absorb road impacts. Guiding mechanisms (such as control arms) are responsible for transmitting longitudinal and lateral forces, while stabilizer bars enhance anti-roll capability. Independent suspension systems, which allow wheels to move independently, usually have 2-3 more connecting components than non-independent suspensions-for example, MacPherson struts add upper support bearings, and multi-link suspensions require additional swing arms. Notably, although small, rubber bushings are crucial for NVH performance; their aging can lead to abnormal noises and loose handling. The precise coordination of suspension components directly affects 80% of the vehicle's handling and 60% of its comfort performance, which is why luxury models often adopt more complex multi-link structures.
