Abstract
The utility model relates to a variable-damping gas spring comprising a cylinder barrel, a base, a piston rod and a piston component assembled on the piston rod, wherein, the piston component assembled on the piston rod is made up of a pair of matching components formed by a piston ring and a piston, one side of the piston is clung to a circulation valve piece, the side surface of the piston ring is connected with the valve piece, one end of the valve piece is connected with a fastening nut, a guider, a seal ring and a positioning sleeve are arranged in the cylinder barrel, a cone-shaped groove is formed on the inner wall of the cylinder barrel, 3-16 passage launders are formed on the piston, and the section of the piston ring is rectangular. The utility model is simple in structure, is not subject to environment, humidity and the viscosity of oil, and is stable and reliable in performance.
Description
Technical field
The utility model relates to a kind of change damping air spring.
Background technique
At present, automobile-used air spring mainly is made up of piston rod in cylinder barrel, the cylinder barrel and piston element etc.Contain gas and part fluid in the cylinder barrel, general air spring commonly used is to have a little damping hole on piston, when piston rod and piston element inwardly compress, cylindrical and the little damping hole of the piston epicoele that flow to cylinder barrel of the gas liquid mixture of the inner cavity of resorption of air spring by piston, when the piston rod of air spring and piston element outwards stretch, the gas liquid mixture of cylinder barrel upside can only flow to the cavity of resorption of cylinder barrel by the little damping hole of piston, make piston rod rate of stretch under the effect of piston element of air spring inconsistent, impact phenomenon easily takes place.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, and stable and reliable operation becomes the damping air spring.
The technical solution of the utility model is achieved in that a kind of change damping air spring, comprises cylinder barrel, base, piston rod and is assemblied in piston element on the piston rod, is contained in piston element on the piston rod by piston ring and the synthetic a pair of matable assembly of piston set; Wherein, a side of piston is close to circulation valve block, piston ring side and valve block joins, valve block one end with tighten up nut and link to each other, in cylinder barrel, be provided with guider, seal ring and setting sleeve, on inner wall of cylinder, be provided with cone tank.Be provided with 3-16 bar passage chute on piston, the cross section of piston ring is a rectangle.
The utility model has the advantages that: simple in structure, be not subjected to the influence of the viscosity of environment and humidity and oil, working stability is reliable.
Description of drawings
Structural representation when Fig. 1 is the utility model compression;
Structural representation when Fig. 2 is the utility model stretching, extension.
Wherein, 1-piston rod, 2-guider, 3-seal ring, 4-setting sleeve, the 5-valve block that circulates, the 6-piston, the 7-piston ring, the 8-valve block, 9-tightens up nut, 10-cylinder barrel, 11-base, 12-diversion groove.
Embodiment
As shown in Figure 1, 2, a kind of change damping air spring comprises cylinder barrel 10, base 11, piston rod 1 and is assemblied in piston element on the piston rod 1 that the piston element that is contained on the piston rod 1 is combined into a pair of matable assembly by piston ring 7 and piston 6; Wherein, a side of piston 6 is close to circulation valve block 5, piston ring 7 sides and valve block 8 joins, valve block 8 one ends with tighten up nut 9 and link to each other, in cylinder barrel 10, be provided with guider 2, seal ring 3 and setting sleeve 4, on cylinder barrel 10 inwalls, be provided with cone tank 12.Be provided with 3-16 bar passage chute on piston 6, the cross section of piston ring 7 is a rectangle.
During the utility model work, as shown in Figure 1, when the piston rod 1 of air spring under external force, piston rod 1 and on piston element inwardly compress, the gas liquid mixture of cylinder barrel 10 cavity of resorptions of air spring is by valve block 8,3-16 bar passage chute on piston ring 7 and the piston 6, flow to the epicoele of cylinder barrel 10 again through the short slot of circulation valve block 5. after the external force of the piston rod 1 that is added in air spring disappears, as shown in Figure 2, under the effect of piston element pressure at two ends difference, piston rod 1 and piston element will outwards freely stretch, because piston ring 7 is close to the side and the cylinder barrel 10 interior circles of valve block 8, then the gas liquid mixture of cylinder barrel 10 epicoeles can only flow to the cavity of resorption of cylinder barrel 10 by cone tank 12, because the width of the cone tank 12 on cylinder barrel 10 inwalls is arranged to by wide to narrow, structural type from deep to shallow gradually, damping function also increase gradually thereupon, and then the speed that outwards freely stretches of the piston rod 1 of air spring and piston element will be slowed down gradually, cause most zero, it is reliable and stable when work to make it air spring.
