Abstract
The present invention relates to an EP2 gaseous core which is also named as a Germany gaseous core. The EP2 gaseous core comprises a gaseous core main body with a through hole in an inner step shape. Outer screws are arranged at the upper end of the gaseous core main body and are connected with a tire charging device of a vehicle, and a cylinder surface with a step is arranged under the outer screws. A circular ring groove is arranged under the cylinder surface, and a charging prismatic surface is arranged under the circular ring groove which is provided with a seal ring. A transversal ventilation hole is arranged under the seal ring. The gaseous core main body is made from zinc-base alloy material. The through hole in the step shape, the cylinder face with a step, the circular ring groove provided with the seal ring, and the charging prismatic surface are formed from zinc-base alloy material by a hot injection moulding technique. The present invention has the advantages that the zinc alloy material and the hot injection moulding technique are used for replacing copper alloy and a processing technique thereof, the production cost is greatly reduced, the manufacturing technique is simplified and the production cycle is shortened; the EP2 gaseous core is widely used for air charging systems of vehicles of various bicycles, boosting vehicles, battery vehicles, small electric vehicles, etc.
Description
Technical field
The present invention relates to a kind of Tire Inflation System.Particularly relate to a kind of EP2 gaseous core that adopts zinc base alloy to make.The EP2 gaseous core is referred to as to call moral formula gaseous core again, and it is widely used in the inflator of vehicle tires such as bicycle, storage battery car and small-sized electric car.
Background technique
At present, the manufactured materials of the domestic EP2 gaseous core that generally uses and method of manufacturing technology be by the bar of Cuprum alloy as raw material through turning be shaped, account for the hole, screw thread is processed and electroplating surface processing etc. is finished by multiple working procedure; This not only takes a lot of work, time-consuming, and what is more important is the strategic resource of national precious as raw-material Cuprum alloy, and price is higher; Making the EP2 gaseous core and be widely used in the inflator of various types of vehicles tire with Cu alloy material is very unfortunate really.
Summary of the invention
Purpose of the present invention is exactly in order to overcome above-mentioned deficiency of the prior art, and a kind of EP2 gaseous core that adopts zinc base alloy thermoforming, manufacturing process advantages of simple is provided.
The objective of the invention is by providing a kind of EP2 gaseous core to realize with following manufactured materials and method of manufacturing technology, it comprises that one has the gaseous core main body of interior step-like through hole, the upper end of described gaseous core main body is provided with the outside thread of the inflator that is used to connect vehicle tyre, described outside thread below is provided with cylndrical surface with the level, below, described cylndrical surface is provided with the annular groove of a dress seal ring, described annular groove below is provided with the inflation cylinder, described inflation cylinder lower end is provided with the hemisphere outer rim, the end of described hemisphere outer rim is provided with an aperture, described aperture is connected with step-like through hole in the described gaseous core main body, the inner of described hemisphere outer rim, and above described aperture, be provided with one and stop the packing that leaks of inflation, described annular groove is provided with a seal ring, and described seal ring below is provided with the horizontal communication hole of a described gaseous core main body.
Described gaseous core main body is to be made by Zn-base alloy.The Zn-base alloy of described gaseous core main body is the zinc base alloy of zinc content more than 80 percent.
