What Are the Types of Automotive Suspension Systems?
1 Answers
Here is an introduction to the types of automotive suspension systems: 1. Non-independent suspension system: The structural feature of a non-independent suspension system is that both wheels are connected by an integral frame, and the wheels, along with the axle, are suspended under the frame or body via an elastic suspension system. Non-independent suspension systems offer advantages such as simple structure, low cost, high strength, easy maintenance, and minimal changes in front-wheel alignment during driving. 2. Independent suspension system: In an independent suspension system, each wheel is individually suspended under the frame or body via an elastic suspension system. Its advantages include: lightweight, reducing the impact on the body, and improving the ground adhesion of the wheels; the use of softer springs with lower stiffness enhances ride comfort; and it allows for lowering the engine position. (1) MacPherson suspension system: The MacPherson suspension system also involves wheels sliding along the kingpin, but it differs from the candle suspension system in that the kingpin can swing. The MacPherson suspension system is a combination of the swing-arm and candle suspension systems. (2) Transverse arm suspension system: The transverse arm suspension system refers to an independent suspension system where the wheels swing within the transverse plane of the vehicle. It is further divided into double-wishbone and single-wishbone suspension systems based on the number of transverse arms. (3) Multi-link suspension system: The multi-link suspension system consists of (3–5) rods combined to control the positional changes of the wheels. It allows the wheels to swing around an axis at a certain angle to the vehicle's longitudinal axis, serving as a compromise between transverse and longitudinal arm suspension systems. (4) Leaf spring non-independent suspension system: Leaf springs are used as the elastic elements in non-independent suspensions. Since they also function as guiding mechanisms, the suspension system is greatly simplified. This type of suspension is widely used in the front and rear suspensions of trucks. (5) Active suspension system: The active suspension system is a new type of suspension system developed in recent decades and controlled by a computer. It integrates knowledge from mechanics and electronics and is a relatively complex high-tech device.
