1results about How to "Adjust flow speed" patented technology

The utility model relates to shock absorber technical field, and disclose a shock absorber internal hydraulic buffer stop structure, including the first cylinder, the first cylinder inner wall top is fixedly connected with the second cylinder, the oil cavity is formed between the first cylinder and the second cylinder, the second cylinder inner wall is provided with buffer stop mechanism. Through buffer stop mechanism realizes double buffering effect. When piston rod drives piston to move downward, second fixed ring moves down with piston, extrudes lift ring, makes buffer spring compression, utilizes the elastic deformation of spring to absorb vibration energy, provides first buffering, when piston continues to move down and approaches limit position, second fixed ring and the rubber block of first fixed ring top contact, the elastic buffer of rubber block further reduces piston descending speed, realizes second buffering. Double buffering mechanism not only effectively reduces vibration transmission, still can prevent piston and cylinder rigid impact under extreme working condition, prolongs shock absorber life.
