Abstract
The utility model provides an air pressure damper, which comprises an air pressure cylinder. An opening is installed at the lower end of the air pressure cylinder, an extensible rod extends into the opening, and the outer wall of the extensible rod is matched with the opening of the air pressure cylinder. The cross section of the upper end of the extensible rod is matched with the inner wall of the air pressure cylinder, the outer wall of a lateral side of the air pressure cylinder is connected with an air pressure bottle provided with an inflation and deflation nozzle, and the top end of the air pressure bottle and the bottom end of the extensible rod are respectively provided with an upper connection point and a lower connection point. The air pressure damper is simple in structure, convenient to use, free of oil leakage like oil pressure dampers, low in carbon and capable of adjusting softness and hardness of the damper, saving resource and protecting environment.
Description
Technical field
The utility model belongs to the auto parts machinery field, specifically is a kind of pneumatic bumper.
Background technique
Vibration damper is used on the automobile, the concussion when mainly being used for suppressing bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, though the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper is too soft, and vehicle body will jump up and down, and vibration damper will bring too big resistance too firmly, hinders the spring proper functioning.The vibration damper that uses at present generally all is an oleo-gear, needs to use oil, has wasted the energy, and leakage of oil easily, and damping effect is good inadequately, and the soft or hard that can not regulate vibration damper.
The model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of pneumatic bumper.
A kind of pneumatic bumper is characterized in that comprising a pressure tank, and there is an opening lower end of said pressure tank; Flexible rod inserts in the said opening; The outer wall of flexible rod and the opening of pressure tank cooperatively interact, and the upper end cross section of flexible rod and the inwall of pressure tank cooperatively interact, and the side outer wall of pressure tank connects an air-pot; Be provided with on the air-pot and charge and discharge valve, the top of pressure tank and flexible rod bottom are provided with tie point and following tie point respectively.
Described pneumatic bumper is characterized in that between the opening of the upper end of flexible rod cross section and pressure tank, being provided with seal ring.
Described pneumatic bumper is characterized in that the said joint that valve is arranged on air-pot top and pressure tank that charges and discharge.
The pneumatic bumper of the utility model, simple in structure, easy to use, can leakage of oil as oleo-gear, and the soft or hard that can regulate vibration damper, save the energy, low-carbon environment-friendly.
Description of drawings
Fig. 1 is the structural representation of the pneumatic bumper of the utility model;
Among the figure, 1-pressure tank; 2-air-pot; 3-charge and discharge valve; 4-seal ring; 5-flexible rod; 6-upward tie points; 7-following tie point.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1; The pneumatic bumper of the utility model comprises a pressure tank 1, and there is an opening lower end of pressure tank 1; Flexible rod 5 inserts in the said opening; The opening of the outer wall of flexible rod 5 and pressure tank 1 cooperatively interacts, and the upper end cross section of flexible rod 5 and the inwall of pressure tank 1 cooperatively interact, and the side outer wall of pressure tank 1 connects an air-pot 2; The joint of air-pot 2 tops and pressure tank 1 is provided with and charges and discharge valve 3, and the top of pressure tank 1 and flexible rod 5 bottoms are provided with tie point 6 and following tie point 7 respectively.Be provided with seal ring 4 between the upper end cross section of flexible rod 5 and the opening of pressure tank 1.
During pneumatic bumper work, be installed on the automobile, from charge and discharge valve, charge into gas through last tie point and following tie point; Concussion when coming bounce-back after the damping spring shock-absorbing and from the impact on road surface through gas atmosphere; If vibration damper is too hard, resistance is too big, when hindering the spring proper functioning; Can bleed off some gases through charging and discharging valve, make the vibration damper deliquescing; If vibration damper is too soft, vehicle body will jump up and down, can charge into some gases through charging and discharging valve, makes the vibration damper hardening.Seal ring 4 can prevent that gas from spilling.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all is included within the protection domain of the utility model.
