Abstract
The invention relates to a method and a device for sealing a self-sealing air spring seam port. The method is characterized in that the side face of the end part of the seam port face of an air spring ballonet is provided with two projected rib lines, and two grooves are also arranged at the corresponding position of an air spring cover plate conical surface, which is matched with the side face of the end part of the seam port face of the air spring ballonet; the positions and the sizes of the grooves are completely inosculated with the projected rib lines on the side face of the end part of the seam port face of the air spring ballonet; under the action of internal pressure, after the seam port is pressed to the cover plate conical surface and is assembled in position, the two projected rib lines of a ballonet seam port are inlaid in the grooves of the cover plate conical surface; the seal-sealing effect of a rubber capsule upper seam port of a rubber air spring is enhanced by the embedded match of the projected rib lines of the air spring ballonet seam port surface and the grooves of the air spring cover plate conical surface at the corresponding position. The key point of the invention lies in sizes, shapes and positions of the ballonet rib lines and the grooves of the cover plate, and the specific design size is obtained on a great amount of tests. The invention can completely solve the problem existing in the matching of self-sealing air spring seam ports.
Description
Technical field
The rim of the mouth partial structurtes that the present invention relates to a kind of pneumatic spring are improved, and are a kind of rim of the mouth selfsealings mode and structure of pneumatic spring specifically.Mainly be exclusively used in the selfsealings of the rubber air spring in the track traffic.
Technical background
Present air spring seam ports selfsealings design mainly is to make the air bag and the taper fit face of cover plate up and down form interference fit through interior pressure.Air-spring bellows can be divided into dual mode with being connected of upper cover plate, selfsealings and bolton mode.
Selfsealings mode up and down rim of the mouth all is that the selfsealings of usefulness connect, and what adopted in the rim of the mouth on the bolt seals mode is that bolt connects, and the selfsealings that remain adopted of rim of the mouth connect down.Therefore the bolt seals mode has still adopted the selfsealings connection in following rim of the mouth.
Its advantage of selfsealings mode is easy to assembly; Can realize the lateral displacement of bigger air spring system with less air bag section girth, shortcoming is, if air bag and cover plate conical surface magnitude of interference are too big; The one, assemble not in place, the 2nd to change air bag very difficult because too tightly make.If air bag and cover plate conical surface magnitude of interference are too little, the one, cause gas leakage easily, the 2nd, air bag and cover plate come off easily in hoisting process, cause security incident.Present selfsealings mode does not all have effective head it off.Find to have similar patent documentation report through patent retrieval:
1, German Kang Ditai (spy) gram air spring system Co., Ltd is in the ZL200580020845.6 patent of China's application, and this patent belongs to typical selfsealings mode.
2, German Kang Ditai (spy) gram air spring system Co., Ltd is in the ZL200580035131.2 patent of China's application, and this patent also is the selfsealings mode.
But above-mentioned two patents design does not still fundamentally solve the problems referred to above that air spring seam ports selfsealings Placement exists.
Summary of the invention
The present invention is primarily aimed at the deficiency of selfsealings design in rim of the mouth on the rubber air spring rubber bag tank in the existing track traffic, proposes a kind of rim of the mouth selfsealings mode and device on air bag and cover plate come off easily in the rim of the mouth selfsealings gas leakage and hoisting process the succinct rubber air spring rubber bag tank that can effectively prevent on the pneumatic spring.
According to the technology implementation scheme that the object of the invention proposed: a kind of self-sealing air spring seam ports sealing means; On the end sides of air-spring bellows rim of the mouth face, be provided with two protrusion muscle line; The pneumatic spring cover plate conical surface same position that matches in the end sides with air-spring bellows rim of the mouth face simultaneously is provided with the groove of twice, and protrusion muscle line matches on the end sides of the position of groove and fully big or small and air-spring bellows rim of the mouth face.Under interior pressure effect, after the air bag rim of the mouth was pressed into the cover plate conical surface and is seated, the muscle line of the twice protrusion in air bag rim of the mouth was bumped into the groove of the cover plate conical surface.Protrusion muscle line through air-spring bellows rim of the mouth face improves the self-packing sealing effect in rim of the mouth on the rubber air spring rubber bag tank with embedded cooperation of the groove of pneumatic spring cover plate conical surface same position.
The particular location size of protrusion muscle line and groove is following: following rim of the mouth and lower cover plate are main, and the size of last rim of the mouth and upper cover plate is equal to lower cover plate and following rim of the mouth.First road protrusion muscle line is positioned on 2/3 position of whole side height on the following rim of the mouth, and second road protrusion muscle line is positioned on the position of whole side height 1/2.And being shaped as of protrusion muscle line is circular-arc, and the radius of circular arc is 1.2-1.7mm; Protrusion muscle line and side are the tangent transition of circular arc, and transition arc radius is 1.0-1.4mm; And the groove on the lower cover plate is corresponding fully with the position of following rim of the mouth protrusion muscle line, and wherein corresponding first road of first groove location protrudes the muscle line, corresponding second road of second groove location protrusion muscle line position.
The invention has the advantages that:
1. adopt the present invention can arrive three purposes simultaneously from close mode:
A: air tight.
B: assembling air bag or replacing air bag are convenient.
C: air bag and cover plate do not come off in the process of lifting.
Traditional rim of the mouth matching design mainly is to confirm air bag rim of the mouth angle [alpha] 1, diameter of phi
1With the angle [alpha] 2 of the cover plate conical surface, diameter of phi
2Between interference.Such as: α 1≤α 2, Φ
1＜Φ
2But this design can't fundamentally solve above-mentioned B, the problem of two aspects of C.
The design's key is the size of air bag muscle line and cover plate groove, shape, position.Concrete design size is on a large amount of experiment basis, to obtain.This invention can solve the existing problem of present matching of self-sealing air spring seam ports fully.
