What is the difference between independent suspension and non-independent suspension?
2 Answers
The differences between independent suspension and non-independent suspension are: 1. Different structures: Independent suspension means that each side's wheels are individually connected to the body via elastic suspension; non-independent suspension means that both sides of wheels are connected by an integrated frame, and the wheels along with the axle are suspended under the body. 2. Different characteristics: Independent suspension reduces the overall impact on the body and improves wheel traction; non-independent suspension has a simple design structure, is lighter in weight, and occupies less space. 3. Different classifications: Independent suspension is mainly divided into MacPherson strut, double wishbone, multi-link, etc. Most modern cars use independent suspension systems; non-independent suspension commonly includes torsion beam non-independent suspension, trailing arm non-independent suspension, and leaf spring non-independent suspension.
The difference between independent suspension and non-independent suspension mainly lies in how the wheels move. Independent suspension means each wheel has its own system, so they don't interfere with each other when bouncing up and down, resulting in less vibration inside the car on bumpy roads and better stability when turning. For example, when I drive long distances on highways with independent suspension, I don't feel the car swaying left and right, and passengers in the back seat also find it more comfortable. Non-independent suspension, on the other hand, is more like a traditional design where the wheels are connected, so if one side bumps, the other side is affected too, causing more shaking inside the car on rural dirt roads. This is common in older pickup trucks or some SUVs, with the advantage of simpler structure but poorer comfort. If you often drive on smooth city roads, the superiority of independent suspension is obvious, especially when taking turns in rainy weather for better safety.
