► The gearbox mount usually includes a body connecting frame and a rubber assembly, and the rubber assembly acts as shock absorber and support.
.A modular design uses an inserted core to achieve efficient variable pre-compression of the rubber spring. This results in better high-frequency isolation, leading to improved vehicle interior noise and significant weight and cost savings. 
The essential feature of the product are the rubber flaps on both sides of the main spring. The thickness and height of these flaps can be tuned to target multiple frequencies by different designs, thus, the vehicle interior noise is improved and high frequency isolation is better.
Metal hardness, rubber hardness, etc, are adapt to the performance requirements.
