The top glue of the shock absorber is the last shock-absorbing layer, which helps to reduce the impact force of the spring when it functions. When the spring is pressed to the bottom, we will feel a strong impact from the wheel. When the damping rubber is still good, the impact sound is "bang", and when the damping rubber fails, the impact sound is "bang". The impact force is very large, which not only causes damage to the shock absorber, but also may cause deformation of the wheel hub.
The interaction between the top rubber molecules of shock absorbers can hinder the movement of molecular chains, exhibiting viscous characteristics, resulting in stress and strain often being in an unbalanced state. The curly long-chain molecular structure of rubber and the weak secondary forces between molecules make rubber materials exhibit unique viscoelastic properties, resulting in good shock absorption, sound insulation, and cushioning performance. Rubber parts for automobiles are widely used for isolating vibrations and absorbing impacts due to their characteristics of hysteresis, damping, and the ability to undergo reversible large deformations. In addition, rubber also has hysteresis and internal friction characteristics, which are usually represented by a loss factor. The larger the loss factor, the more obvious the damping and heat generation of rubber, and the more obvious the shock absorption effect.
Rubber shock absorbers play an important role in the partial shock absorption and buffering of cars, and are important rubber components of cars. Shute Rubber reminds that the main shock-absorbing rubber products used in cars include rubber tension springs, rubber air tension springs, engine suspension shock absorber top rubber, rubber cone shock absorbers, plug shaped rubber shock absorbers, and various shock-absorbing rubber pads, which are respectively used in the engine and transmission system, front and rear suspension system, vehicle body and exhaust system, etc. Its structure is mainly a composite product of rubber and metal plate, and there are also pure rubber parts. From the trend of development abroad, the number of shock absorbers used in cars has always been increasing. To improve ride comfort, both the amount and quality of shock absorber rubber have been developed, and each sedan has 50-60 points of use of shock absorber rubber parts. After entering the 21st century, the safety, comfort, and convenience of cars have become the primary concerns of users. Although the production of sedans has not increased significantly, the amount of shock-absorbing rubber still shows an increasing trend.
The strength of the shock absorber top glue proves that even the smallest object can play an irreplaceable role. When we encounter a pit while driving, the rubber spring plays a significant role in ensuring that we maintain balance and continue driving on uneven roads. There are also some key components whose shock absorbers can withstand the pressure on the parts.
