Abstract
The utility model relates to a silicon oil shock absorber comprising a silicon oil basin containing silicon oil, a rubber column which is hermetically fixed at an upper port of the silicon oil basin and a damping plate arranged at the bottom part of the rubber column; and a clearance is formed between the periphery of the damping plate and the inner wall of the silicon oil basin, and oil storage space is formed between the upper end surface of the damping plate and the bottom surface of the rubber column. In the silicon oil shock absorber, the rubber column is used as a moving part, viscous friction is produced in damping fluid during the vibration and eddy is further formed, thereby consuming vibration energy and further reducing vibration. Therefore, the silicon oil shock absorber has the characteristics of realizing simple structure and being applicable to reducing noise and enabling a driver and passengers to be more comfortable.
