Abstract
The utility model relates to Piston Machining technical field, specifically a kind of gasoline engine aluminum piston with valve hole.A kind of gasoline engine aluminum piston with valve hole, it is characterized by: being respectively equipped with one group of valve hole in the main thrust side of aluminum piston top surface and secondary thrust sides, one group of valve hole is made of two valve holes, and two valve holes are located at the upside and downside of aluminum piston top surface, and two valve holes are that mutual mirror surface is arranged；The side in valve hole is the arc structure of outwardly convex, and one end of arc structure is equipped with valve and cheats overlap, and valve cheats overlap and the outside piston of aluminum piston connects；The other side in valve hole is vertical structure, the other end of one end connection circular arc of vertical structure, the outside piston of the other end connection aluminum piston of vertical structure.Compared with the existing technology, according to the performance requirement of aluminum piston, the structure in valve hole on piston is improved, optimization piston valve cheats the design of overlap, is designed to the shape of " √ ", improves the overall quality of aluminum piston.
Description
Technical field
The utility model relates to Piston Machining technical field, specifically a kind of gasoline engine aluminium with valve hole is living
Plug.
Background technique
Since the high compression ratio of piston of gasoline engine is increasing, to need to increase valve hole in piston-top surface to avoid work
When plug moves to top dead centre and valve interference.But deeper valve hole structure and biggish valve hole diameter will lead to valve hole
The case where the distance between outside piston is very few, has sharp side, burr, necessarily leading to piston in use in this way influences its property
Energy.
Summary of the invention
The utility model in order to overcome the deficiencies of the prior art, provides a kind of gasoline engine aluminum piston with valve hole.
To achieve the above object, a kind of gasoline engine aluminum piston with valve hole is designed, including aluminum piston, feature exist
In: it is respectively equipped with one group of valve hole in the main thrust side of aluminum piston top surface and secondary thrust sides, one group of valve is cheated by two
Valve hole composition, and two valve holes are located at the upside and downside of aluminum piston top surface, and two valve holes are mutual mirror surface
Arrangement；The described valve hole is in " √ " type structure, and the side in valve hole is the arc structure of outwardly convex, and arc structure
One end is equipped with valve and cheats overlap, and valve cheats overlap and the outside piston of aluminum piston connects；The other side in valve hole is vertical structure,
The other end of one end connection circular arc of vertical structure, the outside piston of the other end connection aluminum piston of vertical structure.
One group of valve hole of the main thrust side is that mutual mirror surface is arranged with one group of valve hole of secondary thrust sides.
The valve hole overlap is more than or equal to 3.4mm at a distance from the first annular groove of aluminum piston.
The width of the valve hole overlap is more than or equal to 1.2mm.
The utility model compared with the existing technology, according to the performance requirement of aluminum piston, improves the structure in valve hole on piston,
Optimization piston valve cheats the design of overlap, is designed to the shape of " √ ", improves the overall quality of aluminum piston.
Detailed description of the invention
Fig. 1 is the utility model structure top view.
Fig. 2 is the utility model structural front view.
It is that valve cheats overlap referring to Fig. 1, Fig. 2,1,2 be outside piston, and 3 cheat for valve, and 4 be aluminum piston, and 5 be the first annular groove
5。
Specific embodiment
The utility model is described further below according to attached drawing.
As shown in Fig.1 and Fig.2, one group of valve hole, institute are respectively equipped in the main thrust side of 4 top surface of aluminum piston and secondary thrust sides
The one group of valve hole stated is made of two valves hole, and two valves holes 3 be located at 4 top surface of aluminum piston upside and under
Side, two valve holes 3 are arranged for mutual mirror surface；The valve hole 3 is in " √ " type structure, and the side in valve hole 3 is convex
The arc structure risen, and one end of arc structure is equipped with valve and cheats overlap 1, and valve cheats the outside piston of overlap 1 and aluminum piston 4
2 connections；Valve hole 3 the other side be vertical structure, vertical structure one end connection circular arc the other end, vertical structure it is another
The outside piston 2 of end connection aluminum piston 4.
One group of valve hole of main thrust side is that mutual mirror surface is arranged with one group of valve hole of secondary thrust sides.
Valve cheats overlap 1 and is more than or equal to 3.4mm at a distance from the first annular groove 5 of aluminum piston 4.
The width that valve cheats overlap 1 is more than or equal to 1.2mm.
According to the performance requirement of aluminum piston, the structure in valve hole on piston is improved, optimization piston valve cheats the design of overlap,
It is designed to the shape of " √ ", improves the overall quality of aluminum piston.
