What is a MacPherson suspension[汽车维修知识]

Macphersan type suspension is a kind of independent suspension. It is one of the most popular independent suspensions today. It is generally used on the front wheels of cars.
Simply put, the main structure of the MacPherson suspension is the spiral spring plusShock absorberComposition, the shock absorber can avoid the forward, backward, left and right deviation of the coil spring when the coil spring is stressed, limit the spring to only vibrate up and down, and can be set by the stroke length and tightness of the shock absorber The hardness and performance of the suspension.
However, the MacPherson suspension performs satisfactorily in terms of driving comfort. Its structure is not large and can effectively expand the seating space in the car. However, because of its straight-tube structure, it lacks resistance to impacts in the left and right directions.brakeNodding is less effective.
The MacPherson suspension was born in response to the appearance of front-engine front-wheel drive (FF) models. FF models not only require the engine to be placed horizontally, but also increase the gearbox, differential, drive mechanism,Steering machine In the past, the front suspension space had to be compressed and greatly deleted. Therefore, engineers designed a space-saving, low-cost MacPherson suspension to meet thecarneed . At present, the front and rear suspension of general cars are basically MacPherson or its variants.
Mcpherson (Mcpherson) is a personal name. He is a native of Illinois, USA, born in 1891. After graduating from university, he worked in aero engines in Europe for many years, and joined the General Motors Engineering Center in 1924. In the 1930s, GM’s Chevrolet wanted to design a real small car, and the chief designer was McPherson. He is very interested in designing small cars. The goal is to control the quality of this four-seater car within 0.9 tons and the wheelbase within 2.74 meters. The key to the design is the suspension. McPherson changed the prevailing front suspension method of leaf springs and torsion bar springs, creatively combining shock absorbers and coil springs, and mounted them on the front axle. Practice has proved that this type of suspension has a simple structure, a small footprint, and good maneuverability. Later, McPherson moved to Ford. In 1950, the two vehicles produced by Ford's subsidiary in the United Kingdom were the first commercial vehicles in the world to use McPherson suspension. Due to its simple structure and superior performance, the MacPherson suspension is praised as a classic design by experts.
