McPherson suspension (MacPhersan), is now a very common form of independent suspension, mostly used in front of the vehicle. Briefly, ignition coil pack the main structure of the McPherson suspension coil spring that is coupled with the A-arm and the lower shock absorber composed of the damper can be avoided by the coil spring force of the forward, backward, left, right shift phenomenon, limiting spring only for vertical vibration, and can travel through the shock absorber damping and coil springs with different hardness properties of suspension tuning.

McPherson suspension biggest feature is the relatively small size, it is beneficial for more compact engine compartment layout. But it is precisely because of its simple structure, can not provide adequate lateral support efforts, thus turning the roll and the brakes are quite obvious nod. Here I will explain in detail the structure and performance of McPherson suspension.

● McPherson suspension History:

     McPherson suspension is to be a front-engine front-wheel drive (ff) models appear born. ff models not only requires the engine to be placed horizontally, but also to increase the gearbox, differential, drive mechanism, 328ic Camber Plates steering, front suspension previous space had to be compressed and sharp deleted, so engineers was to design a space-saving, low-cost the McPherson suspension in order to meet the demand for cars.

     McPherson (Macphersan) The suspension system is the inventor's name, he was Illinois man, born in 1891. After graduation he worked in Europe for many years engaged in aircraft engines, and joined GM's engineering center in 1924. 1930s, GM's Chevrolet company wanted to design a truly small cars, the chief architect of that McPherson. He was very interested in small car design, the goal is to control the quality of this four-seater car within 0.9 tons, less than 2.74 m wheelbase control key design is suspended. McPherson was a change in the prevalence of leaf spring front suspension with torsion bar springs way, creatively shock absorbers and coil springs together, put the front axle. Practice has proved that such a suspension in the form of simple structure, small footprint, and excellent maneuverability. Later, 318i Camber Plates McPherson switched to Ford, 1950 Ford subsidiaries in the United Kingdom produced two cars, is the first to use McPherson strut goods vehicles in the world.
