The present invention provides a kind of air spring air feed high intensity plug type gas holder structure, is not only simple in structure, improves
The strength and stiffness on gas seat pipe road, and avoid the defects such as welding deformation, improve sealing property.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of air spring air feed high intensity plug type gas holder structure, described gas holder structure includes intermediate, trachea and mistake
Cross plug；Described intermediate laterally offers through hole, and bottom is provided with air inlet, and trachea extends transversely through intermediate through hole；Described
One end of trachea be provided with pipe screw thread, the other end is provided with transition plug, and in the middle part of trachea, tube wall has circular hole, enters with intermediate bottom
Pore communicates；
As present invention further optimization, transition plug one end processes pipe screw thread, and the other end stretches into trachea, at convex and trachea
It is welded and fixed；
As present invention further optimization, described trachea adopts the stainless steel making of major-diameter thick-wall, and trachea runs through intermediate
Through hole, is welded and fixed with intermediate；
As present invention further optimization, the Circularhole diameter communicating with intermediate air inlet in the middle part of trachea is slightly larger than air inlet；
As present invention further optimization, described gas holder structure bottom is welded and fixed with sleeper beam, trachea two ends are stretched
Go out sleeper beam two coxostermum；
As present invention further optimization, intermediate, trachea and transition plug are all made using stainless steel.
By above technical scheme, with respect to prior art, the method have the advantages that
(1) present invention adopts a major diameter trachea to pass through intermediate, and structure is simple, and the intensity that improve gas seat pipe road is with just
Degree is it is easy to group is welded and installed；
(2) group weldering is carried out using thick walled steel tube and intermediate, the welding performance of trachea can be effectively improved, it is to avoid welding is burnt
Wear, the defect such as welding deformation, improve sealing good；
(3) the opened Circularhole diameter of trachea tube wall is more than intermediate bottom inflow hole, is easy to and intermediate group weldering positioning, it is to avoid in
Damage cutter during mesosome air inlet polish reaming, improve the machinability in intermediate bottom inflow hole；
(4) it is connected one end with differential valve pipeline and adopts integral transition stopper structure, welding can be avoided to destroy trachea, transition simultaneously
Plug is effectively prevented spatter and enters pipe；
(5), after assembling with sleeper beam, transition plug is located at outside sleeper beam, if transition plug damage meeting gas leakage occurs, can be outer in pillow
Excision transition plug, directly changes, easy to maintenance；
(6) present configuration is simple, is skillfully constructed, technology for processing and assembling is good, and the intensity not only increasing gas seat pipe road is with just
Degree, and avoid weld defect between gas seat pipe road and intermediate, thus improve the sealing property of gas seat, welding performance, resisting
Fatigue behaviour and product quality, have good repair and maintenance performance, solve the internal gas seat leakage problem of sleeper beam, can extensively answer
For field of track traffic railroad coach and city railway vehicle, there is good market prospect.
