What does suspension type mean?

Suspension refers to all the force-transmitting connection devices between the vehicle frame or monocoque body and the axle or wheels. Suspension types are mainly divided into independent suspension and non-independent suspension. Introduction to independent suspension: The suspension structure of each wheel is independent, and the movement of a single wheel does not affect other wheels, such as multi-link suspension and MacPherson suspension. Introduction to non-independent suspension: This means that wheels on the same axle are connected through the axle or other forms, so the movement of one wheel affects the other. A typical example is the solid axle non-independent suspension used in body-on-frame structures, which is commonly applied in trucks and large buses. There is also a semi-independent suspension, which belongs to the non-independent suspension category. Many sedans currently use this lower-cost suspension structure, which is an intermediate form between independent and non-independent suspensions on monocoque body structures, such as trailing-arm and torsion-beam suspensions.
I've always thought that suspension types are essentially the design of how a car's chassis connects to its wheels, somewhat similar to how human leg joints move. Common types include independent suspension, where each wheel can move up and down individually, providing better shock absorption when driving over bumpy roads, ensuring a smoother ride for passengers. This type is widely used in sedans and family SUVs. Then there's non-independent suspension, like when the rear wheels are rigidly connected, often seen in off-road vehicles. It's simple and durable in structure but might produce a bumpy and uncomfortable ride on city paved roads. Having driven to work for over a decade, I've learned that choosing the right suspension type is crucial. Independent suspension helps maintain stability on highways, prevents rollovers during turns, and makes parking easier. It also ensures tires grip the road better, enhancing traction and reducing slippage in rainy conditions. Poor suspension design can make a car uncontrollable, like a runaway horse. Regularly checking springs and shock absorbers during maintenance is a proactive measure to prevent issues.
As someone who frequently engages in car modifications, the suspension type is the soul that affects a car's handling for me. Suspension types are broadly divided into independent and non-independent. Independent suspension allows each wheel to move freely, which is why my beloved car feels rock-solid when taking high-speed corners after modifications, with no body sway. Non-independent suspension has a simpler structure, making it suitable for off-road driving but less flexible and prone to bumps. Different suspension types offer distinct driving experiences: independent suspension provides strong grip on the track, with more precise acceleration and braking, while non-independent suspension is more durable when carrying heavy loads or off-roading. Having modified several cars, I've found that choosing the right suspension can enhance overall performance—for example, independent suspension in urban driving saves fuel and reduces noise. If the suspension type isn't suitable, tire wear accelerates, and the driving experience suffers significantly. Beginners should understand this first to avoid feeling like they're on a rollercoaster after modifications.
