What is the difference between independent and non-independent suspension?
2 Answers
The difference between independent and non-independent suspension lies in their structure, as detailed below: 1. Independent suspension means that each side's wheel is individually mounted to the frame or body via an elastic suspension system. 2. Non-independent suspension means that both wheels are connected by an integrated frame, and the wheels along with the axle are mounted to the frame or body via an elastic suspension system. The advantages of non-independent suspension are as follows: 1. The left and right wheels are interconnected during bouncing, resulting in minimal changes in tire angle and reduced tire wear. 2. When the vehicle height is lowered, the wheel angle is less likely to change, maintaining consistent handling feel. 3. Simple construction, low manufacturing cost, and easy maintenance. The advantages of independent suspension are as follows: 1. Lightweight and improves wheel traction. 2. Lower engine position enhances driving stability. 3. Left and right wheels move independently, reducing body tilt and vibration.
I've been driving for over ten years and have driven various cars, and I've found that the difference between independent suspension and non-independent suspension is significant. Independent suspension has its own separate system for each wheel, like individual small springs. When going over a bump, the left wheel shakes while the right one remains unaffected, providing stable handling during high-speed turns or on rough roads without much bumpiness. Non-independent suspension connects the wheels together, sharing a single frame, so when hitting an uneven surface, the entire car body shakes—commonly found in cheaper models. When I drove a non-independent suspension car on dirt roads back in my hometown, the bumps were unbearable. After switching to a car with independent suspension, it felt like driving on smooth ground. Over time, I've come to appreciate that independent suspension offers better handling and higher comfort, though repairs can be more expensive. Non-independent suspension is simpler and more budget-friendly, suitable for daily commuting, but excessive vibrations can lead to fatigue. When choosing, consider road conditions and budget—non-independent is sufficient for city paved roads, while independent is better for mountainous terrain.
