How many types of suspensions are there?

[Curtis]

Suspensions are divided into 7 types, which are: 1. Double-wishbone suspension; 2. MacPherson suspension; 3. Multi-link suspension; 4. Double transverse arm suspension; 5. Double ball joint suspension; 6. Torsion beam suspension; 7. Solid axle suspension. The suspension is the general term for all the force-transmitting connection devices between the vehicle's frame and the axle or wheels. The functions of the suspension are: 1. To provide cushioning when the vehicle passes over uneven ground; 2. To ensure that the wheels move within a fixed angle, making steering stable; 3. To support the weight of the wheels; 4. To maintain good contact between the wheels and the ground, ensuring that the driving force and braking force generated between the wheels and the ground are accurately transmitted to the vehicle body.

When it comes to suspension classification, we can divide them into two main categories: independent suspension and non-independent suspension, based on their structure. Independent suspension means each wheel is connected separately and can move independently, like the family car I drive—it handles bumpy roads really well without much jolting. Non-independent suspension, on the other hand, connects the wheels together and is commonly found in pickup trucks or some SUVs. It's simple, durable, and can handle heavy loads, but the handling isn't as responsive as independent suspension. Breaking it down further, independent suspension includes MacPherson strut and double-wishbone types. MacPherson is cheaper and easier to maintain, making it suitable for regular cars, while double-wishbone is better for sports cars to enhance handling. For non-independent suspension, the torsion beam is a common example. When choosing, consider the purpose: for daily commuting and comfort, go for independent suspension; for hauling or off-roading, non-independent is more reliable. Don’t overlook suspension maintenance either—regularly check the shock absorbers and springs to avoid oil leaks or strange noises that could affect driving safety. Oh, and when new cars hype up their suspension performance, don’t be fooled—test driving is the most practical way to judge.
