Automobile suspension system is an important part of the car, and different types of suspension systems have their own advantages and disadvantages. For 2023, we take a look at three common suspension systems: MacPherson, Double-Difference Arm and Multi-link, each with its own unique performance benefits.
MacPherson suspension is one of the simplest suspension systems, the lowest manufacturing cost, and the most versatile. It features a swingarm and strut geometry that automatically adjusts wheel camber to adapt to the road surface when cornering, maximizing tire contact area. This kind of suspension is suitable for small cars and most medium-sized cars, but due to the simple structure, the suspension stiffness is weak, the stability is poor, and there will be obvious roll phenomenon when turning.
The double-arm suspension has two upper and lower rocker arms, which absorb lateral forces at the same time, and the struts only carry the weight of the vehicle. By using unequal-length rocker arms up and down, the wheels automatically change camber when moving up and down, and reduce track variation and tire wear. This suspension can also adapt to the road surface and has good ground fit, but because there is an extra upper swingarm, more space is required, so the front axle of a small car generally cannot be arranged with this kind of suspension.
Multi-link suspension is a system that combines the restraining of a double-arm suspension with a connecting shaft. With different numbers and configurations of linkages (usually three-link, four-link, five-link), multi-link suspension achieves all the performance of double-arm suspension and changes the toe-in angle of the tire when moving up and down. This makes the multi-link suspension more adaptable to corners, and in the front suspension of front-wheel drive cars, it can alleviate understeer and give the feeling of precise steering. In the rear suspension, it changes the toe angle of the rear wheels, allowing the rear wheels to steer with the front wheels for comfortable handling.
Mr. Zhang, an automotive engineer, said: "MacPherson, double differential arm and multi-link are the three common suspension systems at present, each with its own advantages and scope of application. Choosing the right suspension system depends on the type of vehicle and the needs of use. ”
According to statistics, the current double wishbone independent suspension and multi-link suspension are independent suspension systems. However, the double wishbone suspension is less used because it is easy to cause large changes in the wheel base when the wheel jumps, and the tire wear is aggravated, so it does not meet the requirements of high-speed driving. The multi-link independent suspension can keep the wheels and the ground as vertical as possible due to the role of the connecting rods, reduce the tilt of the body, and maintain the closeness of the tires.
Automotive expert Professor Wang pointed out: "MacPherson, double differential arm and multi-link are three common automotive suspension systems. Each of them has different structures and characteristics, and there is no absolute good or bad. It is very important to choose the right suspension system for your vehicle. ”
Different types of suspension systems have a direct impact on a car's performance and driving experience. Consumers need to choose the right suspension system according to their needs and preferences when buying a car. At the same time, car manufacturers also need to choose the right suspension system according to the characteristics and uses of different vehicle models to provide better driving experience and safety performance.
Automobile suspension system is an important part of the car, and different types of suspension systems have their own advantages and disadvantages. MacPherson, double-differential arms, and multi-link suspension systems are still common choices in 2023. Choosing the right suspension system is crucial to improving the performance and driving experience of your car.
