In the pneumatic spring proposed in patent documentation 1 to 8, in the deflated condition, the stop component metalwork configured at the upper contact with stop component is when main loading direction top offset (decline), other structure members relative with stop component metalwork on the direction vertical with main loading direction, sometimes with this stop component metal pieces into contact.In the case, stop component metalwork is subject to the surface friction drag produced because of the contact with other structure members, due to the impact of this surface friction drag, may hinder the smooth displacement of stop component metalwork on main loading direction.Thus, can not give full play to and the lower contacts of stop component metalwork and spring constant (elasticity) that the stop component that configures has, its result, there is the problem of the good resiliency being difficult to guarantee under deflation status.
Summary of the invention
The present invention proposes in view of the foregoing, its object is to provide a kind of pneumatic spring of resiliency when can improve venting by effectively playing the elasticity of stop component.
Pneumatic spring of the present invention has: the 1st supporting part; 2nd supporting part, it, when observing from the 1st supporting part, main loading direction configures at spaced intervals with the 1st supporting part; The barrier film of elastically deformable, it is by being connected the 1st supporting part with the 2nd supporting part and forming enclosed space; 3rd supporting part, it, when observing from the 2nd supporting part, is configured in that side contrary with the 1st supporting part; The stop component of elastically deformable, it is configured on stop component supporting surface, this stop component supporting surface is some in the 1st opposing side, the 2nd opposing side or the 3rd opposing side, wherein, 1st opposing side is the face of that side relative with the 2nd supporting part of the 1st supporting part, 2nd opposing side is the face of that side relative with the 1st supporting part of the 2nd supporting part, and the 3rd opposing side is the face of that side relative with the 1st supporting part of the 3rd supporting part; And the 4th supporting part, it is when observing from stop component, is configured in that side contrary with the 2nd stop component supporting surface side.1st opposing side or the 2nd opposing side are formed with guide portion, and this guide portion is protruding upward in the side along main loading direction, on the direction vertical with main loading direction, relative with the 4th supporting part.At least one face in the face of the face relative with guide portion of the 4th supporting part and the relative with the 4th supporting part of guide portion, becomes the face that the coefficient of kinetic friction reduces.
In pneumatic spring of the present invention, at least one face in the face of the face relative with guide portion of the 4th supporting part and the relative with the 4th supporting part of guide portion, becomes the face that the coefficient of kinetic friction reduces.Therefore, in the deflated condition, when the 4th supporting part to contact with guide portion and at main loading direction top offset, the surface friction drag that the 4th supporting part is subject to due to the contact with guide portion is inhibited.Thus, compared with situation about not reducing with the coefficient of kinetic friction, the 4th supporting part can displacement more smoothly on main loading direction.Its result, can give full play to the elasticity that the stop component that is configured with the 4th supporting part has.Therefore, according to pneumatic spring of the present invention, a kind of pneumatic spring of resiliency when can improve venting by effectively playing the elasticity of stop component can be provided.
In above-mentioned pneumatic spring, the 4th supporting part also can be configured to, on the direction vertical with main loading direction, spaced apart with guide portion.
Thus, when the 4th supporting part at main loading direction top offset, contacting of the 4th supporting part and guide portion can be suppressed.Its result, can make the displacement more smoothly on main loading direction of the 4th supporting part.
In above-mentioned pneumatic spring, guide portion also in the mode relative with the outer circumferential face of the 4th supporting part, can be formed on the 1st opposing side or the 2nd opposing side.Like this, in above-mentioned pneumatic spring, the more simple resiliency constructed when improving venting can be adopted.
Above-mentioned pneumatic spring still can have the outside stop component of elastically deformable, and when observing from the 2nd supporting part, this outside stop component is configured in that side contrary with the 1st supporting part side.In addition, outside stop component can have multiple hard layer and the structure alternately laminated on main loading direction of elasitic layer.Thereby, it is possible to improve the resiliency of pneumatic spring when exitting further.
In above-mentioned pneumatic spring, stop component such as also can have the drum being formed with hollow portion.Like this, the shape as stop component can adopt various shape.
In above-mentioned pneumatic spring, stop component also can become the state be compressed on main loading direction.Thus, the decrement of stop component during venting reduces further, its result, can reduce the deflection of car body further.
In above-mentioned pneumatic spring, also can be formed with curved part in the region comprising peripheral part of the 4th supporting part, this curved part protrudes in the mode close to stop component supporting surface side.Thus, the distance of the 4th supporting part and stop component supporting surface reduces further, and when exitting, the 4th supporting part easily abuts with the parts being configured in stop component supporting surface side.Its result, the decrement of stop component during venting reduces further, can reduce the deflection of car body further.
In above-mentioned pneumatic spring, also at least one face in the face relative with the 4th supporting part of the face relative with guide portion of the 4th supporting part and guide portion can be configured with smooth parts.In addition, also at least one face in the face relative with the 4th supporting part of the face relative with guide portion of the 4th supporting part and guide portion can be formed with cover coat.
Thus, when the 4th supporting part to contact with guide portion and at main loading direction top offset, more effectively can suppress the surface friction drag that the 4th supporting part is subject to because of the contact with guide portion.Its result, can make the displacement more smoothly on main loading direction of the 4th supporting part.
In above-mentioned pneumatic spring, guide portion also in the mode relative with the inner peripheral surface of the 4th supporting part, can be formed on the 1st opposing side or the 2nd opposing side.More particularly, also can form the hollow portion surrounded by inner peripheral surface on the 4th supporting part, guide portion is relative with inner peripheral surface by being formed in this hollow portion.In addition, stop component also can be made to have the drum being formed with hollow portion, and guide portion is formed as the hollow portion being positioned at stop component.By adopting above-mentioned structure, compared to the situation forming guide portion in the mode relative with the outer circumferential face of the 4th supporting part, the structure of pneumatic spring can be made compacter.
In above-mentioned pneumatic spring, stop component also can be made to become the state be compressed on main loading direction.Thus, the decrement of stop component during venting reduces further, its result, can reduce the deflection of car body further.
In above-mentioned pneumatic spring, also at least one face in the face relative with the 4th supporting part of the face relative with guide portion of the 4th supporting part and guide portion can be configured with smooth parts.Thus, when the 4th supporting part to contact with guide portion and at main loading direction top offset, more effectively can suppress the surface friction drag that the 4th supporting part is subject to because of the contact with guide portion.Its result, can make the displacement more smoothly on main loading direction of the 4th supporting part.
