Cross logical oil sheet and removable insole pieces is connected with piston, and the diameter of piston is less than the diameter of cylinder ends, forms circumferential weld between the two
Gap.
Lead to and between oil sheet and removable insole pieces, be provided with guard circle.
The fairlead of socket piston rod it is provided with in cylinder body rod chamber end.
Open slot it is provided with on piston.
It is provided with floating piston in cylinder body rodless cavity, between floating piston and cylinder body rodless cavity end, constitutes floating piston
Air chamber.
Cylinder body rodless cavity end is provided with monaural.
The air spring of described unidirectional damping type, its cylinder body rodless cavity and rod chamber are sealed with hydraulic oil, floating piston gas
Indoor are sealed with gases at high pressure, and free state piston rod is retracted；
When there being pulling force effect, piston rod stretches out, and removable insole pieces and guard circle move right under the pressure of fluid, oil circuit
Closing, fluid passes through on the right side of the open slot flow direction on piston, and open slot provides damping action, and floating piston is moved to the left, and compensates
The shared volume of fluid when piston rod stretches out；
When there being thrust, piston rod indentation, in cylinder barrel removable insole pieces and guard circle under the pressure of fluid to the left
Side shifting, oil circuit opens, fluid by the circumferential weld clearance flow of piston and cylinder body to the left, floating piston under oil liquid pressure to moving to left
Dynamic.
The technique effect of the present invention: bidirectional damper is become unidirectional damping by damp type air spring of the present invention, and increases floating
Piston, plays buffering, compensates fluid effect, and this is simple and reliable for structure, exports stable unidirectional damping power.

Detailed description of the invention
The present invention will be further described with embodiment below in conjunction with the accompanying drawings:
Referring to Fig. 1, the air spring of unidirectional damping type of the present invention includes cylinder body, piston rod, logical oil sheet, piston, activity mat
Sheet.Wherein, piston is arranged on hollow cylinder inside and cylinder interior is divided into rod chamber and rodless cavity.Cylinder body rodless cavity and have bar
Chamber is sealed with hydraulic oil.Logical oil sheet and removable insole pieces are arranged on piston side, are socketed in piston rod one end, wherein, removable insole pieces
As opening and closing valve, open and close rod chamber and the oil circuit of rodless cavity fluid, form the form in unidirectional damping hole, make air spring have list
To damping action.
Piston rod is arranged in cylinder body rod chamber, and one end passes cylinder ends, and the other end is through removable insole pieces with piston even
Connecing, and the diameter of piston is less than the diameter of cylinder ends, form circumferential weld gap between the two, fluid is moved by circumferential weld clearance flow.
The air spring of described unidirectional damping type, leads to and is provided with guard circle between oil sheet side and piston rod.
It is provided with the fairlead of socket piston rod in cylinder body rod chamber end, piston rod is guided.
Being provided with open slot on piston, the open slot on piston forms damping hole, produces damping action.When piston rod stretches out
Valve is closed, and the open slot on piston forms damping hole, produces damping action；During piston rod indentation, valve is opened, piston rod
Open slot does not play damping action, reverse undamped effect.
It is provided with floating piston in cylinder body rodless cavity, between floating piston and cylinder body rodless cavity end, constitutes floating piston gas
Room, is sealed with gases at high pressure in floating piston air chamber.Described floating piston plays buffering, compensating action, it is to avoid stretch out at piston rod
Time rodless cavity in the phenomenon of evacuation occurs, it is provided that stable unidirectional damping power.
Cylinder body rodless cavity end is provided with monaural.
The air spring of described unidirectional damping type, its free state piston rod is retracted.
When there being pulling force effect, piston rod stretches out, and removable insole pieces and guard circle move right under the pressure of fluid, oil
Road is closed, and fluid passes through on the right side of the open slot flow direction on piston, and open slot provides damping action, and floating piston is moved to the left, and mends
Repay the shared volume of fluid when piston rod stretches out.
When there being thrust, piston rod indentation, in cylinder barrel removable insole pieces and guard circle under the pressure of fluid to the left
Side shifting, oil circuit opens, fluid by the circumferential weld clearance flow of piston and cylinder body to the left, floating piston under oil liquid pressure to moving to left
Dynamic.
The removable insole pieces of the air spring of unidirectional damping type of the present invention, as opening and closing valve, opens and closes rod chamber and rodless cavity fluid
Oil circuit, formed unidirectional damping hole form, make air spring have unidirectional damping effect.Simultaneously by increasing floating piston composition
2 air chambers, makes fluid and gas barrier, has buffering, the function of compensation fluid, thus exports stable unidirectional damping power.
