Difference 1: Structure
The independent suspension system is that the wheels on each side are individually suspended under the frame or body through the elastic suspension system.
Instead of independent suspension, the wheels on both sides are connected by an integral frame, and the wheels, together with the axle, are suspended under the frame or body through an elastic suspension system.
Difference 2: Advantages
The advantages of independent suspension are light weight, reduce the impact of the overall body, and improve the adhesion of the wheels. Compared with non-independent suspension, it is most prominent in comfort.
The advantages of non-independent suspension are simple design structure, lighter weight, and small space occupation. Compared with independent suspension, its most prominent feature is its high strength.
Difference 3: Application
Independent suspension can be divided into Macpherson type, double wishbone type, link strut type, multi-link type, etc. Most modern cars adopt independent suspension system. In application, independent suspension is obviously more important than non-independent suspension. More extensive.
The most commonly used non-independent suspension is nothing more than torsion beam non-independent suspension, trailing arm non-independent suspension and leaf spring non-independent suspension. In modern cars, only models with stricter cost control will be used, and more are used for trucks. And on the bus.
Difference 4: Disadvantages
The independent suspension system has the disadvantages of complex structure, high cost, and inconvenient maintenance. At the same time, because of the complex structure, it will encroach on some passenger space in the car.
Non-independent suspension is relatively poor in comfort and handling stability, so it generally needs to be adjusted to achieve the effect of independent suspension.
