The upper chamber is occupied by the piston rod 2 for a part of space, so that the increased volume of the upper chamber is smaller than the decreased volume of the lower chamber, which results in the volume of the hydraulic oil being larger than the volume of the hydraulic cylinder 1, and the stress of the hydraulic oil on the hydraulic cylinder 1, the sealing cover 9, and the like is not avoided, preferably, a circular cavity 12 is formed between the bottom wall of the hydraulic cylinder 1 and the cylinder piston 5 disposed below the hydraulic cylinder 1 at an interval, and a compression valve 13 and a compensation valve 14 are disposed on the bottom wall of the hydraulic cylinder 1, and are used for opening when the oil pressure in the hydraulic cylinder 1 increases, so that the hydraulic oil of the hydraulic cylinder 1 flows into the circular cavity 12, that is, when the increased volume of the upper chamber is smaller than the decreased volume of the lower chamber, a part.

The saving of hydraulic oil by the extension valve 10, the flow valve 11, the compression valve 13 and the compensation valve 14 results in a damping force for the compressed movement of the suspension. On the contrary, when the shock absorber is in an extension stroke, the wheel is far away from the vehicle body, and the shock absorber is stretched. At this time, the hydraulic piston 3 of the shock absorber moves upwards, the oil pressure of the upper cavity of the hydraulic piston 3 rises, the circulation valve 11 is closed, the hydraulic oil in the upper cavity pushes away the extension valve 10 and flows into the lower cavity, the oil flowing from the upper cavity is insufficient to fill the increased volume of the lower cavity due to the existence of the piston rod, a vacuum degree is generated in the lower cavity, and at this time, the hydraulic oil in the circular cavity 12 pushes away the compensation valve 14 and flows into the lower cavity for supplement. The throttling effect of these valves damps the suspension during the extension movement.
Referring to fig. 1, the operation of the damping tunable shock absorber for air suspension provided in the present embodiment will now be described in detail:
during the compression stroke, for example, the vehicle wheels move closer to the vehicle body, the shock absorber is compressed:
when the force is small, the piston rod 2 drives the hydraulic piston 3 and the dust cover 6 to move downwards; the pressure piston 3 moves downwards, the volume of the lower chamber of the hydraulic piston 3 decreases, the oil pressure increases, and the hydraulic oil flows to the chamber (upper chamber) above the hydraulic piston 3 through the flow valve 11. The upper cavity occupies a part of space by the piston rod 2, so that the increased volume of the upper cavity is smaller than the reduced volume of the lower cavity, a part of hydraulic oil pushes away the compression valve 13 and flows into the circular cavity 12 and the U-shaped cavity body 15, and the expansion valve 10, the flow valve 11, the compression valve 13 and the compensation valve 14 save the hydraulic oil to form damping force of the suspension under compression movement; at the same time, the dust cover 6 moves downwards to compress the elastic member 7 between the upper bracket 61 and the lower bracket 41, so that the elastic member 7 generates a damping force in the axial direction of the hydraulic cylinder 1 to damp the compression movement of the suspension; that is, when the force is small, the hydraulic oil in the hydraulic cylinder 1 and the elastic element 7 act together to generate damping force;
along with the increase of the acting force, when the hydraulic piston reaches the extreme position, the damping effect is not played any more, and at the moment, the piston rod 2 drives the hydraulic piston 3 and the dust cover 6 to move downwards; the hydraulic piston 3 drives the hydraulic cylinder 1, the cylinder piston 5 and the sliding cylinder body 8 to integrally move downwards along the inner wall of the cylinder 4, and at the moment, compressed air can be continuously compressed to generate larger damping force which is increased continuously; the dust cover 6 also moves downwards along with the piston rod 2 relative to the cylinder 4, and compresses the elastic part 7 between the upper bracket 61 and the lower bracket 41, so that the elastic part 7 generates a damping force along the axial direction of the hydraulic cylinder 1 to damp the compression motion of the suspension; that is, when the force is large, the hydraulic oil, the compressed air and the elastic member 7 in the hydraulic cylinder 1 act in cooperation to generate the damping force.
During the extension stroke, the shock absorber is far away from the vehicle body at the wheel, and the shock absorber is pulled:
a piston rod 2 of the shock absorber drives a hydraulic piston 3 and a dust cover 6 to move upwards; the oil pressure of an upper cavity of the hydraulic piston 3 is increased, the circulating valve 11 is closed, and hydraulic oil in the upper cavity pushes away the extension valve 10 and flows into a lower cavity; because of the existence of the piston rod 2, the hydraulic oil flowing from the upper cavity is not enough to fill the increased volume of the lower cavity, so that the lower cavity generates a vacuum degree, and the hydraulic oil in the circular cavity 12 and the U-shaped cavity 15 pushes away the compensating valve 14 to flow into the lower cavity for supplement; the dust cover 6 moves upwards to stretch the elastic member 7 between the upper bracket 61 and the lower bracket 41, so that the elastic member 7 generates a damping force along the axial direction of the hydraulic cylinder 1 to damp the stretching motion of the suspension; that is, the hydraulic oil in the hydraulic cylinder 1 and the elastic member 7 act in concert to generate a damping force.
In summary, in the damper with adjustable damping for an air suspension provided by the embodiment, when the road condition is simple and the acting force is small, the external acting force generates the damping force through the cooperative action of the hydraulic oil in the hydraulic cylinder and the spring; along with the increase of the acting force, after the hydraulic piston reaches the extreme position, the hydraulic piston does not play a role in shock absorption any more, and at the moment, the compressed air and the elastic part can be continuously compressed to generate larger damping force which is increased no more; the realization provides different damping force to the condition of difference, reaches the effect of automatically regulated damping, according to the damping force of this bumper shock absorber of different automatic adjustment of road conditions promptly to improve the travelling comfort and the shock attenuation effect of whole car, enlarged the road conditions accommodation of vehicle.
