How many types of automotive chassis suspension systems are there?
2 Answers
Automotive chassis suspension systems are classified as follows: 1. Dependent suspension: Vehicles equipped with this type of suspension system generally have poorer stability and comfort. However, due to its simpler structure and high load-bearing capacity, this suspension is mostly used in trucks, ordinary buses, and some other special vehicles. 2. Independent suspension: The structure of independent suspension includes various types such as trailing arm, MacPherson, and multi-link. It can reduce body vibration, improve vehicle comfort, and enhance driving stability on high-speed roads. Most passenger cars now adopt independent suspension for both front and rear, which has become a development trend.
There are several common types of automotive chassis suspension systems. From my years of driving experience, I've learned that non-independent suspension, also known as rigid axle suspension, is simple and durable but offers poor comfort, commonly found in older vehicles or trucks. Independent suspension includes MacPherson strut, which is compact and suitable for regular sedans; multi-link suspension consists of multiple links, providing stable cornering and good handling, often used in high-performance sports cars; double-wishbone suspension allows flexible wheel movement and precise control, making it ideal for racing cars. There's also torsion beam suspension, which is a compromise between independent and non-independent types, offering cost-effectiveness for small cars. The suspension type directly affects driving experience—for example, on bumpy roads, MacPherson can absorb more vibrations, while non-independent suspension causes more jolts, affecting long-distance comfort. When choosing a car, I consider suspension performance based on road conditions and budget, and maintenance requires regular checks on shock absorbers and springs.
