Embodiment Construction
[0037] The present invention is further described below in conjunction with specific embodiment, and specific embodiment is the further description of the principle of the present invention, does not limit the present invention in any way, and identical or similar technology with the present invention all does not exceed the scope of protection of the present invention.
[0038] In conjunction with the accompanying drawings.
[0039] The gas path connector of the automatic coupler is composed of a gas path communication mechanism and an opening and closing mechanism. The opening and closing mechanism is a normally closed, top-opening valve mechanism, which is normally closed by the spring compression valve, and opened by the front sliding rod of the air-way communication mechanism pushing the valve when the coupler is combined;
[0040] The gas circuit communication mechanism is a dual-channel mutual coupling communication mechanism, including a convex end communication struct...

The invention discloses an air channel connector suitable for an automatic car coupler. The air channel connector is composed of an air channel communication mechanism and an opening and closing mechanism, the opening and closing mechanism is a normally-closed and top-open type valve mechanism, normal closing is achieved through a spring compression valve, and opening is achieved through the fact that a front sliding rod of the air channel communication mechanism jacks a valve open when the car coupler is combined. The air channel communication mechanism is a double-channel mutual coupling communication mechanism and comprises a convex end communication structure with an ejector rod and a concave end communication structure with the front sliding rod, and the ejector rod and a radial sealing ring arranged in the concave end communication structure are tightly combined on the peripheral wall of the ejector rod to achieve sealing; and the end face of the concave end communication structure of each channel is in pressing contact with an outer end sealing ring arranged on the combined end face of the convex end communication structure to achieve sealing. Two-stage sealing is adopted, the sealing effect is good, the air drift diameter of the connector is large, the connecting force is adjustable, the ejector rod is of a floating structure and can float in the radial direction, reliable connection during butt joint is ensured, a mutual embracing and communicating structure is adopted, undifferentiated matched connection is achieved, installation is easy, and operation is simplified.
Description
technical field [0001] The invention belongs to the technical field of railway vehicle equipment design, in particular to the technical field of railway vehicle coupling coupler design, and relates to an air circuit connector of an automatic coupler. Background technique [0002] At present, the automatic coupler is mainly a close-connected coupler used by bullet trains and subways, and the connection and separation of the air circuit connector interface are carried out simultaneously with the coupling and uncoupling of the coupler. [0003] The existing automatic couplers often do not have the tight connection characteristics of the tight-fitting coupler, and the sealing performance cannot meet the requirements. When the coupler is connected, the interface of the air circuit connector still deflects, which cannot meet the higher precision allowable conditions of the docking. Moreover, the requirements for the diameter of the gas path on railway freight cars and ordinary spe...
