These suspensions have their own advantages and disadvantages, and different suspensions can be used for different functions of buffering, damping and transmission. The automobile brings vibration, comfort and controllability when driving.

For example, the leaf spring type non-independent suspension is generally not installed on a household vehicle and is mainly suitable for vehicles with high bearing capacity, such as trucks and pick-up trucks; the advantage is that the height is large and the load is strong; the disadvantages are poor comfort and easy abrasion.

The torsion beam type semi-independent suspension is mostly used on middle and low-end vehicle types and has stronger stability; the disadvantages are that the wheels on both sides are affected by the suspension and the comfort is poor.

The double-wishbone type independent suspension has the disadvantage of being expensive to manufacture, and is usually only mounted on high-price medium and high-end vehicles, and is difficult to see by ordinary household vehicles.

The Macpherson type independent suspension has the defects of weaker stability, weaker anti-roll performance, low durability and head nodding phenomenon during braking.

The multi-link independent suspension has the disadvantages of high cost and poor stability.

However, the above suspensions cannot keep the tire perpendicular to the ground all the time during movement, and both the tire and the ground are in a small splayed state during running, so that the inner side of the tire is greatly abraded.
