What is the difference between independent suspension and non-independent suspension in cars?
2 Answers
The differences between independent suspension and non-independent suspension in cars are: 1. Different disadvantages: Independent suspension systems have the disadvantages of complex structure, high cost, and inconvenient maintenance; non-independent suspension systems have poor comfort and handling stability. 2. Different advantages: The advantage of independent suspension is its light weight, which reduces the impact on the overall body and improves wheel traction; the advantage of non-independent suspension is its simple design structure, light weight, and small space occupation. 3. Different structures: In an independent suspension system, each wheel is individually suspended under the frame or body via an elastic suspension system; in a non-independent suspension, the wheels on both sides are connected by an integrated frame, and the wheels together with the axle are suspended under the frame or body via an elastic suspension system.
As an ordinary person who often drives in the city, I feel there's a significant difference between independent suspension and non-independent suspension. Independent suspension allows each wheel to move independently, such as when going over speed bumps—the vibration only affects one wheel, making the ride much more comfortable and reducing excessive shaking. During turns, the car remains stable without excessive body roll. Non-independent suspension, on the other hand, connects all wheels to a single axle, so uneven roads cause vibrations throughout the entire vehicle. I've driven several cars, like SUVs with non-independent suspension—they're cheaper and more durable but deliver a bumpier ride, often making rear passengers complain of motion sickness. Sedans with independent suspension are pricier but offer a smoother daily commute, especially on rough roads. Simply put, independent suspension prioritizes comfort and handling, while non-independent suspension is cost-effective and practical but sacrifices ride quality. For long-term use, if road conditions are poor, I’d recommend independent suspension as the more worthwhile choice.
