The sealing unit guarantees that damping oil does not reveal, and the shock attenuation unit realizes the shock attenuation effect to the car, and the radiating unit carries out the heat dissipation to damping oil and handles, guarantees the shock attenuation effect of shock attenuation unit.
The damping unit comprises a piston rod 2, an inner cylinder 3, a piston head 4, a first one-way valve block 8, a second one-way valve block 9 and an oil passing cavity 5, the piston rod 2 is located inside the inner cylinder 3, and the piston head 4 is matched with the inner cylinder 3. An oil passing cavity 5 is arranged between the inner cylinder barrel 3 and the outer cylinder barrel 1, and a plurality of damping holes 6 communicated with the oil passing cavity 5 are arranged on the side wall of the inner cylinder barrel 3. Two ends of the inner cylinder 3 are respectively communicated with the first oil passage 14 and the second oil passage 15, the first oil passage 14 is provided with a first check valve plate 8, and the second oil passage 15 is provided with a second check valve plate 9. The damping oil flows partially between the inner cylinder 3 and the oil passing chamber 5 through the damping hole 6, and partially flows inside the inner cylinder 3 through the piston head 4.
The fixed unit comprises an end cover 11, an oilless bearing 12, an upper lifting lug 10 and an outer cylinder barrel 1, wherein the upper lifting lug 10 is respectively connected with the outer cylinder barrel 1 and the inner cylinder barrel 3. The end cover 11 is provided with a moving hole matched with the piston rod 2, and an oilless bearing 12 connected with the piston rod 2 in a sliding manner is arranged in the moving hole. The upper lifting lug 10 fixes the positions of the inner cylinder barrel 3 and the outer cylinder barrel 1, and smooth work of the damping unit is guaranteed.

The damping oil in the oil passing cavity 5 enters the lower part of the piston head 4 through the damping hole 6 and enters the nitrogen cylinder 13 through the third oil passing channel 16 for heat dissipation.
The heat dissipation unit comprises a nitrogen cylinder 13, and a first oil pipe and a second oil pipe of the nitrogen cylinder 13 are both communicated with a third oil gallery 16. The nitrogen cylinder 13 carries out heat dissipation treatment on the damping oil entering the nitrogen cylinder, and the cooled damping oil continues to enter the damping unit to work, so that the damping effect of the damping unit is ensured.

Example 1
The damping holes 6 can be distributed on the side wall of the inner cylinder barrel 3 into a plurality of sections, and the number of holes, the aperture and the interval of each section can be different. The piston rod 2 has a smaller damping value at the middle position of the inner cylinder 3, and the piston rod 2 has a larger damping value at the two ends of the inner cylinder 3. The law is synchronous with the law of the bumping degree of the vehicle during running, and the hydraulic anti-collision effect is realized when the two ends of the inner cylinder barrel 3 are not provided with the damping holes 6.
In the compression process of the damping unit, the piston head 4 moves upwards to drive a part of damping oil above the piston head 4 to enter the oil passing cavity 5 along the damping hole 6, and the other part of damping oil enters the lower part of the piston head 4 through the deformed compression valve plate group 17. The damping oil that enters the oil passing chamber 5 partly enters below the piston head 4 along the damping hole 6, and partly enters the nitrogen cylinder 13 along the oil passing chamber 5. During the compression process of the damping unit, the piston head 4 shields a part of the damping holes 6 on the side wall of the inner cylinder 3 according to the relative position change of the piston rod 2 and the inner cylinder 3, thereby generating different damping values.
When the piston head 4 is close to the first one-way valve plate 8, the piston head 4 closes the damping hole 6 above the piston head 4, damping oil above the piston head 4 cannot flow along the first one-way valve plate 8, the hydraulic anti-collision effect is achieved, and the maximum anti-collision value is the opening damping force of the compression valve plate group 17.
In the stretching process of the damping unit, the damping oil in the nitrogen cylinder 13 enters the upper part of the piston head 4 along the first one-way valve plate 8. A part of the damping oil below the piston head 4 enters the oil passing cavity 5 along the damping hole 6, passes through the third oil passing channel 16 and the first oil passing channel 14 in sequence, opens the first one-way valve plate 8 and enters the position above the piston head 4.
When the piston head 4 is close to the second oil passage 15, the piston head 4 closes the damping hole 6 below the piston head 4, damping oil below the piston head 4 cannot flow along the second one-way valve plate 9, the hydraulic anti-collision effect is achieved, and the maximum anti-collision value is the opening damping force of the stretching valve plate group 7.
Therefore, the double-oil-cylinder variable damping structure for the shock absorber with the structure can automatically adjust the damping value according to the vehicle bumping condition, quickly restrain the vehicle bumping and enable a driver and passengers to be in a comfortable state all the time.
