Welcome!

At this time, the resistance to the fluid flow attenuates the extension tension.

8. When the extension shock absorber manufacturers is approaching the limit, the elongation of the rebound spring absorbs the vibration energy, and in this process, the oil is added to the B room through the small hole in the front * piston, preparing for the next work .

Hydraulic damping type rear shock absorber

1. At this time, when the oil flows through the small hole, it will be subject to great resistance, so it has a better damping effect and plays the purpose of damping.

2.When the wheels fall over the raised ground, the cylinder will move downwards, and the piston will move upwards relative to the cylinder.

3. At the same time, this part of electric scooter shock absorber also flows into the oil cavity between the inner and outer cylinder through the small hole on the bottom valve.

4. This effectively attenuates the impact load of the bumpy road on the vehicle.

5.When the rear wheel encounters bumps on the road, the cylinder moves upwards, and the piston moves relatively downward in the inner cylinder. At this time, the piston valve is flushed open upward, and the oil on the lower side of the piston in the inner cylinder cavity flows to the upper side of the piston without any resistance.

6. When the piston moves upward, the oil flushes the valve at the bottom and flows to the inner cylinder. At the same time, the oil on the upper side of the inner cylinder piston flows down through the small hole in the piston valve.

7.The hydraulic shock absorber is the most common adjustable hydraulic shock absorber currently used in motorcycles. The structure of the hydraulic shock absorber is basically similar to that of the suction pump, except that the upper end of the steel body of the hydraulic shock absorber is closed, while the There are small holes in the valve.
