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.

In daily car usage, I notice that suspensions are most commonly categorized into independent and non-independent types. Independent suspensions allow wheels to move independently, like the common MacPherson strut design, which absorbs road vibrations well, making long drives less tiring, though maintenance might be costlier. Non-independent suspensions move wheels together, offering simplicity and affordability, such as the torsion beam used in many compact cars—great for smooth roads but bumpier over potholes, reducing rear-seat comfort. These types impact driving experience: independent suits families or commuters prioritizing quietness, while non-independent is budget-friendly. A few active suspensions auto-adjust stiffness, but the core types remain these two. Before buying, check reviews or test-drive to assess body stability.

I recently studied car knowledge and learned that suspensions are divided into two main categories: independent suspension and non-independent suspension. In independent suspension, each wheel works independently, such as the MacPherson strut, providing flexible handling. Non-independent suspension connects the wheels through a fixed linkage, like a torsion beam, which is simpler in structure. The choice of suspension depends on the intended use—the former offers comfort while the latter is more economical.

As a frequent car modifier, I say the core of suspension systems falls into two categories: independent and non-independent. Independent suspensions like double-wishbone or multi-link allow wheels to move individually, providing strong grip during turns, making them great for high speeds or mountain roads, but not necessarily the most fuel-efficient in stop-and-go city traffic. Non-independent suspensions like torsion beams or trailing arms offer strong structural integrity, preventing sagging when hauling heavy loads, but transmit more vibrations over rough roads. Driving enjoyment often relies on independent suspensions, as they're easier to modify for noticeable improvements. Other types like air suspensions are derivatives of independent systems but don't change the fundamental classification. When modifying cars, pay attention to suspension types as they directly affect acceleration and handling response.
