The leaf spring is a spring made of steel plate and is an elastic element formed by combining a plurality of steel plates. It is also known as a leaf spring. In order to make full use of the material, the leaf spring is made in the form of a stress beam. It has two types, one is equal thickness, and the width exhibits both ends of the gorge, and the middle is wide. The traditional multi-piece leaf spring is this type. This type of leaf spring is made of several steel sheets of different lengths and widths. Most of the buses and trains now use this type of leaf spring. The coil spring is a spiral spring made of spring steel coil. It can be used as an independent suspension elastic component, but also as an independent suspension elastic component, so in the car suspension, especially the independent suspension , Widely used. Its advantages are simple structure, reliable work, low cost and convenient maintenance. The biggest advantage is that it is both the suspension's elastic component and the dominant suspension's guide. It is hinged at one end to the frame and can transmit various moments and moments and determine the trajectory of the wheel. At the same time, it also has a certain friction damping effect. It is used three-fold, so it is widely used on non-independent suspension. The rubber spring uses the elasticity of the rubber itself to act as an elastic element. He can withstand both compressive and torsional loads. Rubber springs are often used as suspension springs and cushions. The advantage of the rubber spring is that the unit mass has more energy storage than the metal spring, sound insulation performance, no noise, no need for lubrication. The structure of the rubber can be freely selected, and the internal friction of the rubber spring is large, so the rubber spring has both a certain ability of vibration reduction. The rubber northern component can be adjusted to control the hardness, with proper damping, which is conducive to crossing the resonance area, attenuating high frequency vibration and noise. The torsion bar spring, which is made of spring steel, has a twisted elastic rod. If a rubber rod is twisted by hand to twist him, he will twist a certain angle and people will feel its elasticity. When relaxed, it will revert to its original condition. Using this principle, the metal torsion bar spring can be used as the elastic component of the automobile suspension. One end of the torsion bar spring is fixedly connected with the frame, and the other end is connected with the suspension control arm. The torsion deformation of the torsion bar achieves the buffering effect. The gas spring is filled with compressed gas (pressure of 0.5~1 moa) in a sealed container and uses the compressibility of the gas to achieve its spring action. The stiffness of the gas spring is variable, because when the load acting on the spring increases, the quantitative gas in the container is compressed, and the gas pressure increases, the stiffness of the spring increases; conversely, when the load decreases, the spring The pressure drops, the stiffness decreases, and the pressure and stiffness inversely relate. Therefore, it has an ideal variable stiffness characteristics. It can not only prolong the service life of the vehicle, but also improve the comfort of the vehicle, reduce the dynamic load of the wheel, and greatly reduce the damage to the road surface of the vehicle, thereby reducing the maintenance cost of the road surface.

Suspension spring types introduced
After more than 100 years of development, the car suspension has now reached hundreds of types. The suspension system of the car was suspended from the initial non-independent suspension to the independent suspension, and then McPherson, double-wishbone etc. were derived from the independent suspension. A wide variety of types and independent suspensions weigh the most advanced design - multi-link suspension. Suspension is an important assembly in the car and has a very direct impact on people's riding comfort. It is one of the standards to evaluate the quality of automotive performance
