Which is Better: Independent Suspension or Non-independent Suspension?
2 Answers
Here are the specific differences between independent suspension and non-independent suspension: 1. Structure: In an independent suspension system, each wheel is individually connected to the frame or body through an elastic suspension system. In contrast, non-independent suspension connects both wheels via a solid axle, which is then attached to the frame or body through an elastic suspension system. 2. Advantages: Independent suspension offers benefits such as lighter weight, reduced impact on the overall body, improved wheel traction, and greater comfort compared to non-independent suspension. Non-independent suspension, on the other hand, is simpler in design, lighter in weight, takes up less space, and is stronger than independent suspension. 3. Applications: Independent suspension can be further divided into types like MacPherson strut, double wishbone, multi-link, and others. Most modern passenger cars use independent suspension systems, making them more widely used than non-independent suspension. Non-independent suspension typically includes torsion beam, trailing arm, and leaf spring types, and is mainly found in cost-sensitive passenger cars, as well as in trucks and buses.
As an ordinary person who frequently drives in the city, I can say that independent suspension performs better in daily driving. When I drive my small car on urban roads, the independent suspension allows each wheel to move individually, so hitting small bumps doesn’t transmit too much vibration, making the ride feel exceptionally smooth and comfortable—no soreness even after long drives. However, non-independent suspension is also quite practical. My old SUV uses it, providing a sturdier body, less jolting over speed bumps, and cheaper, simpler repairs. Overall, if you mainly drive on well-paved roads and prioritize comfort and stability, independent suspension is the better choice. But if you often drive on rough roads or have a tight budget, non-independent suspension is more hassle-free and cost-effective—something I’ve deeply realized from years of driving experience.
