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 each side's wheels are individually connected to the body via elastic suspension; Non-independent suspension means both sides' wheels are connected by an integrated frame, with the wheels and axle together suspended under the body. 2. Different characteristics: Independent suspension reduces overall body impact and improves wheel traction; Non-independent suspension features simple design structure, lighter weight, and smaller space occupation. Additionally, their classifications differ: Independent suspension mainly includes MacPherson strut, double wishbone, multi-link, etc., and most modern cars adopt independent suspension systems; Non-independent suspension commonly includes torsion beam, trailing arm, and leaf spring types.
I've done quite a bit of research on car suspensions. Independent suspension means each wheel has its own suspension system, allowing it to move up and down independently without affecting the others. For example, when the left wheel hits a bump, the right wheel remains stable. This provides a more comfortable ride and precise handling, especially on rough roads or during high-speed turns, with minimal body sway. Non-independent suspension, on the other hand, connects the wheels via an axle, so when one side moves, the other side follows—like how rear passengers feel pronounced movements over speed bumps. In terms of differences, independent suspension is commonly used in the front wheels of sedans or luxury cars to enhance the driving experience, though it's more complex and costly to maintain. Non-independent suspension is cheaper and more durable, often seen in the rear suspension of trucks or entry-level SUVs. When choosing a car, prioritize independent suspension for city driving to reduce fatigue, while for off-road or heavy-load scenarios, consider non-independent suspension for cost savings.
