How many types of suspension systems are there?

Suspension systems can be categorized into three types: independent, non-independent, and semi-independent suspensions. The suspension system refers to all the force-transmitting connection devices between the vehicle's frame and the axles or wheels. Its functions include transmitting forces and moments between the wheels and the frame, cushioning the impact from uneven road surfaces to the frame or body, and dampening the resulting vibrations to ensure smooth vehicle operation. The suspension system also includes components such as shock absorbers, springs, anti-roll bars, and linkages. Among these, springs are devices used to cushion vibrations, absorbing energy through their deformation, with coil springs being the most common type. Shock absorbers generate pressure internally via liquids or gases to move the valve body, thereby absorbing vibrational energy.
There are several types of suspension systems, and I'll share my experience from years of driving. The most basic classification is independent suspension and non-independent suspension. Non-independent suspension, like the rear axle of older cars, means when one wheel bumps, the other shakes too—less comfortable but cheaper to maintain and more durable. Independent suspension is much better, allowing each wheel to move up and down individually, ideal for smooth and comfortable rides. My car uses a MacPherson strut suspension, which is cost-effective and handles daily bumpy roads well. There's also double-wishbone suspension, which provides more stability at high speeds and less body roll in turns. Air suspension is common in luxury cars, offering adjustable stiffness but at a higher cost. Choosing a suspension depends on road conditions and budget, but don’t overlook handling and safety. Poor maintenance can lead to strange noises or misalignment.
