What is McPherson suspension

MacPhersan suspension is now a very common form of independent suspension, mostly used in the front wheels of vehicles. Simply put, the main structure of the McPherson suspension is composed of a coil spring plus a shock absorber and a A line of hem arm, the shock absorber can avoid the phenomenon of forward, backward, left and right offset when the coil spring is stressed, limiting the spring can only be vibrated in the upper and lower directions, and the suspension performance can be adjusted by the stroke of the shock absorber, damping and coil springs with different hardness. The biggest feature of McPherson suspension is that it is relatively small, which is conducive to a relatively compact engine compartment layout. However, it is precisely because of the simple structure that the opposite side cannot provide sufficient support strength, so the steering roll and brake nodding phenomenon are more obvious.

The McPherson suspension consists of coil springs, shock absorbers, A-shaped swing arms, and most models also add lateral stabilizer bars. The physical structure of the McPherson-style independent suspension is a pillar shock absorber doubles as the main pin, withstanding the upper and lower pre-stresses from body shake and ground impact, and the knuckle (also known as the wheel, because the knuckle acts on the wheel) rotates along the main pin; In addition, its main pin can be oscillated, characterized by the main pin position and the front wheel positioning angle with the up and down of the wheel to change with the up and down of the wheel, and the front wheel positioning changes slightly, with good driving stability.
