Strut mounting is the last section of shock absorption, it reduces the impact force on the spring when the spring is working. When the spring is pressed to the bottom, we will feel a strong impact from the wheels. When the strut mounting kit fails, one obvious symptom will be the clunking noises and the impact force will be larger, it will not only damage the shock absorber, but also deform of the wheel hub.

The interaction rubber molecules of strut mounting will hinder the movement of the molecular chain, resulting in the unbalanced state of stress and strain. Rubber has unique viscoelastic properties because of its curly long-chain molecular structure and the weak secondary forces existing between molecules, so it has good performance in shock absorption, sound insulation and buffering. Automotive rubber-metal parts are widely used to isolate vibrations and absorb shocks due to such characteristics as hysteresis, damping and the ability of reversible deformation. In addition, rubber also has hysteresis and internal friction characteristics, which are usually measured by a loss factor, as the loss factor grows the damping and heat generation of the rubber will be more obvious, and the shock absorption will perform better.

Rubber-metal parts for car mainly include rubber springs, rubber air springs, engine mounting, strut mounting, rubber cone shock absorbers, plug-shaped rubber parts and various shock-absorbing rubber pads etc., which are used on engines, transmission systems, front and rear suspension systems, car bodies and exhausting systems. They are mainly rubber to metal parts, but also pure rubber parts. Automobile rubber parts have been showing an increasing trend. In order to improve comfort, both the quantity and quality of rubber parts have been improved. Each car has 50 to 60 pcs of rubber parts. In the 21st century, the safety, comfort and convenience of cars have become the prime requirement of users. Although the vehicle production has not increased much, the need of rubber parts is still increasing.

The strut mounting kit plays an irreplaceable role. It ensures that the car maintain balance and keep driving on the uneven roads.
