1. Noun suspension
refers to the automobile suspension system between the tire and the vehicle body and a suspension spring support system of the entire composition. Suspension system should function is to support the body, improve the ride feeling, different suspension settings make drivers have different driving experience. Looks deceptively simple suspension system integrated a variety of forces determines the stability, comfort and safety of cars is one of the crucial components of modern cars.
2. The suspension system defined in
is a general term for all suspension means of frictional connection between the vehicle frame and axle or wheel, whose role is to pass between the frame and acting on the wheel forces and torsional forces, and to cushion the impact force to the vehicle frame or body by the uneven road, and the resulting vibration attenuation to ensure that cars can travel smoothly. A typical system configuration of an elastic suspension member, the guide mechanism and a damper and other components, as well as the structure of the individual blocks buffer, stabilizer and the like. Another elastic member in the form of leaf springs, air springs, coil springs and a torsion bar spring or the like, and use more modern car suspension coil spring and a torsion bar spring, limousine individual air spring is used. A suspension system is important in the automobile assembly, it is the frame and wheels elastically linked to the relationship of the plurality of performance cars. From the outside, the car suspension system is only a few rods, tube and springs, but do not think it is very simple, opposite a car suspension is more difficult to achieve the perfect vehicle assembly requirements, because not only the suspension system to meet the comfort requirements of the car, but also to meet the requirements of its handling and stability, and these two aspects are contradictory to each other. For example, in order to achieve good comfort, it requires a significant buffer vehicle vibration, the spring must be designed so soft, but soft spring but it is easier to make cars brake happen “nod” to accelerate “rise” as well as serious adverse events roll around the tendency is not conducive to steering a car, easily lead to vehicle handling and instability.
3 independent suspension characteristics
the wheel independent suspension system on each side of the system are individually suspended from the frame or body by elastic suspension below. Its advantages are: light weight, reducing the impact received by the vehicle body, and improves the adhesion of the ground wheels; available small spring stiffness of softer, improve the comfort of the car; the engine can be lowered position, the center of gravity cars also reduced so improve vehicle driving stability; beat separate left and right wheels, independent of each other, can be reduced and vibration of the vehicle body is inclined. However, independent suspension system, there is a complex structure, high cost and maintenance inconvenience shortcomings, at the same time because of the complex structure, it will occupy some of the interior passenger space.
Modern cars are mostly independent suspension system, according to the different structure, independent suspension system can be divided into horizontal arm, a vertical arm, multi-link, candle and McPherson suspension systems. Structural features
4. The non-independent suspension characteristics
non-independent suspension system of each wheel is connected by an integral frame, the wheel together with the axle via an elastic suspension system suspended below the frame or body. Non-independent suspension system has a simple structure, low cost, high strength, easy maintenance, small changes in wheel alignment in road advantages, but because of its comfort and manipulationStability are relatively poor, in modern cars, only more stringent cost control models will be used more for the trucks and buses.
non-independent suspension system advantages:
● be implicated in left and right wheels at each bounce, a small amount of change in angle of the tire so that the tire wear is small.
● height is reduced when the vehicle body is not easy to change the angle of the wheels, so that the feeling of manipulation consistent.
● simple structure, low manufacturing cost, easy maintenance.
● a smaller footprint, the height of the floor panel can be reduced.
non-independent suspension system drawback:
● left and right wheels during bounce, will be involved with each other and reduce comfort and handling stability of the ride.
● due to the simple structure that the design freedom is small, poor stability manipulation.
