The function of top glue of automobile shock absorber, and the function of top glue of shock absorber
For the automobile shock absorber, its existence is to keep the vehicle "stable and comfortable" on the rugged road. Of course, to complete this comfortable and stable mission, the shock absorption effect of the car must be excellent, so that the car will be more stable when walking. However, if the car hears abnormal noise when walking, we usually judge it as the problem of the shock absorber. What is the shock absorber or top glue? Let's take a look at the top glue function of automobile shock absorber with Xiaobian.
Top glue function of automobile shock absorber -- Brief Introduction
The top rubber of the shock absorber is the last shock absorber, which helps the spring reduce the impact force when the spring plays a role. When the spring is pressed to the bottom, we will feel the strong impact from the wheel. When the damping rubber is still good, the impact sound is "bang bang". When the damping rubber fails, the impact sound is "Dangdang" and the impact force is great. It will not only damage the shock absorber, but also cause the deformation of the wheel hub.
Top glue function of automobile shock absorber -- working principle
The interaction between the rubber molecules of the top rubber of the shock absorber will hinder the movement of the molecular chain and show the characteristics of viscosity, so that the stress and strain are often in an unbalanced state. The crimped long chain molecular structure of rubber and the weak secondary force between molecules make the rubber material show unique viscoelastic properties, so it has good shock absorption, sound insulation and cushioning properties. Automotive rubber parts are widely used to isolate vibration and absorb impact because of its lag, damping and reversible large deformation. In addition, rubber also has hysteresis and internal friction characteristics. They are usually expressed by loss factor. The greater the loss factor, the more obvious the damping and heat generation of rubber and the more obvious the damping effect.
