Abstract
The present invention relates to a kind of damping device, relate in particular to the hydraulic shock absorber that can obtain to stablize damping characteristics, in the cylinder of filling fluid, disposing piston, form hyperbaric chamber and low pressure chamber, install curtain-shaped cover member by being arranged between aperture on the described piston and the air layer in the low pressure chamber, in the time of making action of giving at short notice, the flow velocity that flows to the buffering oil of low pressure chamber from described aperture relaxes, thereby can obtain the stable damping device of damping characteristics.
Description
Even the present invention relevant makes piston action with short time interval, also can obtain the damping device of fixed damping characteristics.
Fig. 2 is the sectional drawing of the original damping device of expression, and (1) is the shell of store oil among the figure, and oil cylinder (2) is arranged on its a part of position.(3) for making the piston of oil cylinder slip, which is provided with the aperture (4) in a certain size aperture.(5) spring for piston (3) is returned, (6) are oil, and (7) are lid, and with sealed member (8), (9) make it sealing.(10) be exactly the hyperbaric chamber that becomes high pressure when piston (3) moves, (11) are low pressure chamber, and (12) are the chamber gas-bearing formation.
Next action is explained.In Fig. 2, when apply external force make piston (3) towards illustrated left when being pressed into, the oil pressure in hyperbaric chamber (10) just rises, thereby the cushion effect to external force has just taken place.At this moment, the oil (6) in hyperbaric chamber (10) is by aperture (4), go out to low pressure chamber (11) one effluents with very fast flow velocity, make the air of interior oil (6) of low pressure chamber (11) and air layer (12) obtain stirring, thereafter, as shown in Figure 3, oil (6) settles out.In this state, when removing external force, piston (3) is under spring (5) effect, towards illustrated right-hand action.At this moment, oil (6) in the low pressure chamber (11) flows into hyperbaric chamber (10) by aperture (4), yet just after piston (3) is carried out racking, the occasion that piston is returned, the empty G﹠O (6) that is stirred is sneaked into hyperbaric chamber (10) together.
Damping device originally, owing to constitute as described above, after action, piston (3) is returned, then air is sneaked in the hyperbaric chamber (10), even therefore there has been the action in the short time lag, can not obtain the problem of regular buffer attribute.
The present invention proposes for eliminating problem as described above, even its objective is in the action that obtains in the short time lag, also can obtain the damping device of regular damping characteristics.
About damping device of the present invention is exactly between aperture on being located at piston and the air layer in the low pressure chamber curtain-shaped cover member to be set.
Damping device of the present invention is because the oil that flows out with high speed from aperture when piston action lowers thereby prevented the stirring of the oil and the air of low pressure chamber because of curtain-shaped cover member makes flow velocity.
With reference to the accompanying drawings, one embodiment of the invention are explained.Among Fig. 1, (13) are curtain-shaped cover member, and it is arranged between the aperture (4) and air layer (12) on the piston (3), and other (1)-(12) are the same with original structure.
In oil dashpot as constituted above, when piston (3) moves, from aperture (4) to the oil (6) of low pressure chamber to flow out at a high speed, in case when running into curtain-shaped cover member (13), flow velocity is lowered, from the gap between piston (3) and the curtain-shaped cover member, in low pressure chamber (11), flow out with low speed.Therefore, the stirring of the air of oil (6) in the low pressure chamber (11) and air layer (12) not taking place, even after moving like that, piston (3) is returned, can prevent that air from sneaking in the hyperbaric chamber (10) yet.
As mentioned above, if according to the present invention, flow to the curtain-shaped cover member that the flow velocity of the oil of low-pressure chamber reduces by arranging to make when the piston action from aperture, even obtained the action with the short time interval, also can obtain the effect of the stable buffer unit of damping characteristics.
Below accompanying drawing is done simple declaration.
Fig. 1 is the sectional drawing according to the damping device of one embodiment of the invention,
Fig. 2 is the sectional drawing of original damping device,
Fig. 3 is the 2nd action diagram.
Among the figure, (2) are oil cylinder portion, and (3) are piston, and (4) are aperture, and (10) are the hyperbaric chamber, and (11) are low pressure chamber, and (13) are curtain-shaped cover member.
In addition, prosign is represented same or suitable part among each figure.
Claims (1)
1, disposing piston in the cylinder of filling fluid, form hyperbaric chamber and low pressure chamber, at described piston during towards the action of described hyperbaric chamber, the described fluid that makes described hyperbaric chamber on being provided in described piston fixed aperture flow to the curtain-shaped cover member that is provided with the liquid speed that mitigation flows out from described aperture the device of described low pressure chamber, with this damping device as feature.
