Description
Technical field
The utility model relates to a kind of cylinder head gasket, relates in particular to a kind of internal combustion engine cylinder cover spacer.
Background technique
Internal-combustion engine (petrol engine and diesel engine) all relies on fuel burn to produce explosive force in cylinder combustion and promotes piston to-and-fro motion and doing work in cylinder.The sealability of cylinder head is most important, always is the key technology that improves engine performance, and wherein cylinder-top gasket sheet material and moulding are the most important things.Early stage gland shim adopts horsestone velveteen plate in the double-layer alloy Copper Foil more, and sealing is better but working life is not high; In recent years, adopt the stacked conducting plate embossing again, sealing and working life improve, but working life is still not ideal enough.
Summary of the invention
The utility model provides a kind of good sealing effect, is difficult for deforming the cylinder head gasket of long service life.
The technological scheme of the utility model technical solution problem is:
A kind of internal combustion engine cylinder cover spacer, form by sheet metal and cushion rubber, be provided with cylinder-bore, valve tappet through hole, cooling water through hole on described sheet metal, be provided with the metal ring body to the both sides projection at sheet metal cylinder-bore edge, this metal ring body and sheet metal are one; Be inlaid with cushion rubber at described valve tappet through hole, cooling water through hole edge, this cushion rubber is the rubber ring body to the both sides projection.
Described metal ring body width is 1～3 millimeter, and the metal ring height goes out 0.025～0.1 millimeter on sheet metal plane.
Described rubber ring body width is 1.5～3 millimeters, and the rubber ring body exceeds 0.025～0.1 millimeter on sheet metal plane.
The thickness of described sheet metal is 0.7～2 millimeter.
Described metallic sheet material is carbon steel 08F.
Described rubber ring body material is a fluorine rubber.
Technique effect of the present utility model is: because the utility model adopts individual layer unitary solid sheet metal to make the engine cylinder head system pad, the cylinder-bore edge is provided with the annular solid to the both sides projection, its protruding annular solid can produce good sealing effect, can bear strong wallop for a long time and do not deform, can keep original sealing effect for a long time, improve the working efficiency and the working life of internal-combustion engine greatly.Since the cushion rubber that the utility model adopts high temperature resistant, high voltage bearing fluorine rubber to make be embedded in sheet metal valve tappet through hole, cooling water through hole around, especially cushion rubber is a rubber ring body to the both sides projection, valve tappet through hole, cooling water through hole to easy generation seepage have sealing effectively, the reliability and the working life of improving internal-combustion engine greatly.

Among the figure: 1. sheet metal, 2. cushion rubber, 3. metal ring body, 4. bolt hole, 5. cylinder-bore, 6. valve tappet through hole, 7. cooling water through hole.
Embodiment
Specify below in conjunction with drawings and Examples:
Present embodiment is fit to all types of internal-combustion engines, comprises petrol engine and diesel engine.
To shown in Figure 2, the IC engine cylinder head pad is the closure that is enclosed within the cylinder-bore periphery as Fig. 1.The utility model IC engine cylinder head pad adopts individual layer bulk metal plate, and the thickness c of sheet metal 1 is 0.7～2 millimeter.Sheet metal 1 is provided with the metal ring body 3 to sheet metal face both sides projection at cylinder-bore 5 edges, the metal ring body width a that is positioned at the cylinder-bore edge is 1～3 millimeter, the height b that metal ring body 3 exceeds the sheet metal plane is 0.025～0.1 millimeter, be subjected to the time spent of doing of cylinder bolt when metal ring body 3, metal ring body 3 is subjected to very big pressure because of lifting surface area is very little, cause metal ring body 3 small slit between cylinder cap and body of projection fully to be filled up, the cylinder-bore sealing is greatly enhanced like this.Because sheet metal 1 material adopts carbon steel 08F, this material has very strong high temperature resistant, high voltage bearing performance, can stand the ability of rugged environment in the cylinder-bore for a long time, therefore makes motor have long working life and combustion seal effect preferably.
As Fig. 1, Fig. 3, Fig. 4 and shown in Figure 5, cushion rubber 2 is for being located at the closure of valve tappet through hole 6, cooling water through hole 7 inward flanges.Cushion rubber 2 materials are resistant to elevated temperatures fluorine rubber, heat with specialized mould, by hot vulcanization process attached to the through hole inward flange, cushion rubber 2 is the rubber ring bodies to sheet metal face both sides projection, rubber ring body width e is 1.5～3 millimeters, and the height f that the rubber ring body exceeds the sheet metal plane is 0.025～0.1 millimeter.Cushion rubber 2 causes rubber ring body small slit between cylinder cap and body of projection fully to be filled up when the time spent of doing that is subjected to cylinder bolt, and valve tappet through hole 6, cooling water through hole 7 sealings are greatly enhanced like this.Because cushion rubber 2 residing valve tappet through holes 6, cooling water through hole 7 environment are abominable like that not as cylinder-bore 5, the tolerance performance of cushion rubber 2 self can adapt to fully, thereby can keep long working life and sealing effect.
With Stevr king truck is example, and according to test, the supporting diesel engine of this car adopts horsestone velveteen cylinder cover gasket in the double-layer alloy Copper Foil, the 50000 kilometers not overhauls of can travelling under the normal condition; Adopt single layer alloy waveform cylinder cover gasket, the 100000 kilometers not overhauls of can travelling under the normal condition; Adopt the utility model IC engine cylinder head pad, 300,000～500,000 kilometers not overhauls of can travelling under the normal condition, no matter the utility model IC engine cylinder head pad is sealability, or all obtains effect preferably working life.
