Motor vehicle suspension on the vehicle suspension system is a very important system. Not only does it affect the comfort of the car (ride), but also to other properties such as the adoption, as well as the stability of the attachment have a significant impact on performance, each of the suspension by the elastic components (buffers), body-oriented (from Chuan And stabilizing role), as well as shock absorbers (from the role of shock absorption). However, not all of the suspension must have three components. As long as we can play to the role of the three. Vehicle maintenance for the conservation network 1, flying the classification 1. Non-independent suspension: on both sides of the wheel mounted on a total-vehicle-bridge, the train-bridge to fly through the frame and connected. This suspension structure is simple and reliable power-but by two rounds of shock and vibration affecting each other. But also because of the quality of flying non-serious suspension of the poor performance of the buffer, the vibration of a moving car, the greater the impact. The suspension generally used for trucks, buses and a number of other ordinary vehicles. (2) independent suspension: each individual through a set of wheels mounted on the body or suspension of vehicular bridge, the use of off-Axle, in the middle of a fixed frame or body; such wheel on both sides of the suspension by the shock Hubuyingxiang, but due to non-flying than by the quality; buffer with a strong shock absorption capacity, ride comfort. The indicators are better than non-independent suspension, but the complex structure of the suspension, but it also drive axle, steering system has become complicated. The use of such suspension of the following two categories of vehicles. Cars, buses and passenger vehicles. Can be improved ride comfort, and high speed when driving the car to improve stability.Off-road vehicles, military vehicles and mining vehicles. In a bad way and have no say under the circumstances, we can make sure all the wheels on the ground and contacts to enhance stability and driving the car attached, to play a speed of the car. 2.Flexible yuan for the type of (1) of the leaf spring: the long-range multi-chip and curvature ranging from the composite plate. After installed at both ends of the natural upward curve. In addition to the leaf spring with a buffer, there is a certain degree of shock absorption, vertical layout also has a force-oriented, non-independent suspension using most of the leaf spring so flexible components, save-oriented devices and shock absorbers, simple structure . (2) of the coil spring: only a cushion for the multi-car independent suspension. In the absence of damping force and mass functions must also be equipped with special shock absorbers and device-oriented. (3) oil and gas spring: a flexible medium as a gas, liquid as a medium-power, which not only has a good buffer capacity, also has a role in shock absorption and at the same time frame of a high degree of regulation may also be applicable to the use of heavy vehicles and buses. (4), torsion bar springs; will be made under the torsion bar springs fixed at one end of the frame, on the other side through the arm and connected to the wheels, and beat at wheel torsion bar the use of reverse deformation played the role of buffer, is suitable for independent The use of suspension. 3. the use of shock absorber tube shock absorbers, the use of oil in the small role to cut energy consumption vibration. Shock absorber and the upper body frame or connected with the lower end of the train-bridge connected. Most of the trip can be done and the compression of the dual role of the role of shock absorber.4.device-oriented: the flexibility in the independent suspension components, most of them can only transfer the vertical loads and can not transmit vertical and horizontal, must be a separate device-oriented. As noted, under the arm and vertical, horizontal stabilizer, and so on. 5. non-independent suspension: before and after the truckswere non-independent suspension bridge, some vehicles such as buses and cars and so on, after the bridge is also a non-independent suspension. Each car of the sedan chair by hoisting two independent non-vertical arrangement of the composition of the leaf spring. Leaf spring fixed in the middle of the train-bridge, with the front end hinged frame or body, the back-end with the frame or body through the ear hanging hinged or connected to use of skateboards. Top of the frame with a shock absorber then, with the lower end of the next school Axle. The truck rear axle and more without shock absorbers.6. many types of independent suspension, coil spring as the use of flexible components. Torsion bar springs for the independent suspension is also divided into vertical and horizontal torsion torque Cup two-under. Although many of the advantages of an independent suspension, but the car would turn the system, the Department of driving and driving more compl
