What is McPherson suspension?

The suspension connects the vehicle body to the wheels and has the following functions:
(1) When driving, it absorbs and cushions the various vibrations, swings and impacts of the vehicle body due to road irregularities together with the tires to protect passengers and cargo and improve driving stability.
(2) Transmit the driving force and braking force generated by the friction between the road surface and the wheels to the chassis and the vehicle body.
(3) Support the vehicle body and maintain the appropriate geometric relationship between the vehicle body and the wheels.

1. Non-independent suspension
A suspension in which the wheels on both sides are supported by a bridge housing or bridge and move together.

2. Independent suspension
A suspension in which each wheel is supported by an independent arm mounted on the vehicle body and the wheels on both sides move independently.
(1) Torsion beam non-independent suspension
Torsion beam non-independent suspension is mainly used as the rear suspension of front-engine front-wheel drive vehicles. It consists of a suspension arm welded to the torsionable front bridge and a stabilizer bar (some do not have a stabilizer bar).
(2) Leaf spring non-independent suspension
Leaf spring non-independent suspension is mainly used as the front suspension of small vans and large buses, and the rear suspension of commercial vehicles. This suspension has a simple structure but high strength. Since the spring must ensure a certain rigidity, the ride comfort of vehicles equipped with this suspension is not very good.
(3) McPherson independent suspension: It is a widely used front suspension form for small and medium-sized vehicles.
