The three core characteristics of a suspension system include support, shock absorption, and guidance. Support is achieved through elastic components (such as coil springs or air springs), which bear the weight of the vehicle body and cushion road impacts. Among these, air springs in high-end models can dynamically adjust stiffness to balance comfort and handling. Shock absorption is dominated by shock absorbers (such as hydraulic or pneumatic shock absorbers), which enhance ride smoothness by rapidly dampening vibrations. For example, magnetorheological shock absorbers can adapt to different road conditions through electronic adjustment. Multi-link suspensions, with their multi-dimensional control capabilities, are commonly found in luxury models, while MacPherson struts, due to their compact structure, are the preferred choice for economy cars. Additionally, active suspension systems further integrate these three characteristics by real-time adjusting damping and height, but their high cost limits their use mainly to high-performance vehicles. These characteristics collectively determine a vehicle’s handling stability and ride comfort, and consumers can choose the appropriate suspension configuration based on their needs.
