Abstract
The utility model discloses an air shock absorber used on motorcycles and vehicles, which belongs to a shock absorbing device. The utility model comprises a cylinder body, a piston, a piston rod, an upper supporting seat, a cylinder seat, a sealing device, and a shock absorbing spring, and two mutually reverse spring valves are arranged on the piston. The utility model has the advantages that the manufacture process is simple, the raw material is saved, the manufacture cost is low, the utility model is convenient for maintenance, the service life is long, and the shock absorbing effect is good.
Description
Technical field
The utility model relates to a kind of air bump that is used on motorcycle, the automobile, belongs to a kind of damping device.
Background technique
The vibration damper that present motorcycle is used, major part is medium with lubricant oil, its working life is shorter, in case leakage of oil is promptly scrapped.A tree name interrelated data report, having with the inert gas is the vibration damper of medium, in case gas leakage has also just been scrapped, above-mentioned two kinds of vibration dampers all require good seal, can not take maintenance apart, and are difficult in maintenance, in case leakage of oil or gas leakage then need more renew are wasted bigger.
Summary of the invention
The purpose of this utility model be to overcome the deficiency in the background technique and provide a kind of manufacturing process simple, save raw material, cost is low, the air bump of long service life, good damping effect.
The purpose of this utility model is achieved through the following technical solutions: it comprises cylinder body, piston, piston rod, upper support seat, cylinder seat, seal arrangement, outside cylinder body, be set with damping spring, on piston, be provided with two spring valves of oppositely installing each other, its spring valve is made up of spring, valve ball, voltage regulation screw, spring one end is fixed on the piston by voltage regulation screw, and the spring the other end and valve ball touch.
The utility model compared with prior art has following advantage:
1, because of being medium with the air, seal request is not strict, and manufacturing process is simple, saves raw material, and cost is low, can keep in repair;
2, owing on piston, be provided with two spring valves of oppositely installing each other, when running into when making piston motion than big bang, the air of an air chamber in the cylinder body is compressed, pressurized air is opened a spring valve, another spring valve is in closed condition, when will restoring to the original state, piston begins to do heterodromous moment, the spring valve of opening is closed immediately, and another spring valve is not opened, present vaccuum phenomenon, prevented resonance and damping, the effect of damping spring in addition, thereby good damping effect;
3, overcome the drawback that existing vibration damper can not overhaul, can overhaul at any time, thereby working life
3, overcome the drawback that existing vibration damper can not overhaul, can overhaul at any time, thereby long service life;
When 4, travelling in more smooth highway section, cylinder is stressed slightly, and spring valve is failure to actuate, chamber supercharging of cylinder, another chamber decompression can mode be scattered and disappeared a part of kinetic energy heating, the quite buffer function damping of spring again of part stored energy, it is more comfortable that the people is taken.
The explanation of accompanying drawing drawing
Fig. 1 is the utility model structural representation
Fig. 2 is the utility model piston structure schematic representation
Among the figure: upper support seat 1, damping spring 2, piston rod 3, seal arrangement 4, seal ring 5, cylinder body 6, cylinder seat 7, spring valve 8, piston 9, dust-proof cover 10, valve ball 11, spring 12, voltage regulation screw 13
Specific embodiments
Below in conjunction with drawings and Examples in detail specific embodiments is described in detail, as shown in Figure 1: it comprises cylinder body 6, seal arrangement 4, piston 9, piston rod 3, upper support seat 1, cylinder seat 7, outside cylinder body 6, be set with damping spring 2, piston rod 3 one ends are fixed on the upper support seat 1, the other end passes seal arrangement 4 and stretches into cylinder body 6 and be connected and fixed with piston 9, seal ring 5 is housed on the piston 9, is provided with dust-proof cover 10 on cylinder body 6 tops.On piston 9, be provided with two spring valves of oppositely installing each other 8.This vibration damper is fixed on the car body by upper support seat 1 and cylinder seat 7.As shown in Figure 2, spring valve 8 is made up of spring 12, valve ball 11, voltage regulation screw 13, and spring 12 1 ends are fixed on the piston 9 by voltage regulation screw 13, and spring 12 the other ends and valve ball 11 touch.Two spring valves are oppositely installed each other, and promptly the valve ball 11 of a spring valve 8 is in the bottom of piston 9, and spring 12 is fixed on the top of piston 9 by voltage regulation screw 13; And the valve ball 11 of another spring valve 8 is on the top of piston 9, and spring 12 is fixed on the bottom of piston 9 by voltage regulation screw 13.The pressure control of valve spring is in proper range.When running into than big bang, piston 9 movement therewith, the air of cylinder body 6 interior air chambers is compressed, when the pressure of air chamber surpasses the pressure of spring valve, valve ball 11 towards the spring valve 8 of this air chamber be opened, move smoothly to adapt to piston 9, prevent that vehicle from jolting, when oppositely in a flash this valve close immediately, but another valve is not opened again, piston 9 is in obstructed state up and down, presents vaccuum phenomenon.In addition since piston 9 and spring valve 8 leak in slightly, thereby piston is restored.Another former spring valve of closing 8 is opened when oppositely being shaken, and the former spring valve of opening 8 is in closed condition, enters above-mentioned damping program again, and so work prevents resonance, reaches the purpose of damping.
Claims (2)
1, a kind of air bump comprises that cylinder body, piston, piston rod, upper support seat, cylinder seat, seal arrangement, cylinder body are set with damping spring outward, it is characterized in that being provided with on piston two spring valves of oppositely installing each other.
2, air bump according to claim 1 is characterized in that spring valve is made up of valve ball, spring, voltage regulation screw, and spring one end is fixed on the piston by voltage regulation screw, and the spring the other end and valve ball touch.
