How many types of car suspensions are there?

Car suspensions are divided into two types: independent suspension and non-independent suspension. Independent suspensions can be further categorized into MacPherson strut independent suspension, multi-link independent suspension, double-wishbone suspension, etc. Non-independent suspensions include torsion beam, leaf spring, solid axle, and others. The suspension refers to all the force-transmitting connecting devices between the car's frame (or unibody) and the axle (or wheels). Its function is to transmit forces and torques acting between the wheels and the frame, while also cushioning impacts from uneven road surfaces transmitted to the frame or body, reducing resulting vibrations to ensure smooth driving.
I've driven quite a few cars and found that automotive suspensions mainly fall into two categories: independent suspension and non-independent suspension. Independent suspension means each wheel can move independently without affecting the others, such as MacPherson strut or double-wishbone types. This type feels very comfortable on bumpy roads with minimal body sway, especially preventing rear passengers from getting carsick, which is most noticeable during stop-and-go city driving. Non-independent suspension connects the left and right wheels to a single axle, moving together, like torsion beam or trailing arm types. They are low-cost and durable, stable under load, and won't sag even when carrying large luggage, making them suitable for economy cars or SUV rear ends. Pay attention to this when choosing a car, as there's a significant difference in comfort and handling feel. Some high-end models even feature air suspension for height adjustment, but ultimately, it's the independent or non-independent design that plays the core role.
