Abstract
The invention discloses an air cylinder cover gasket which comprises a frame body and bearing plates, wherein the frame body is provided with a cylinder mouth part and cylinder cover bolt tack hole parts; the frame body is a single-layer plate except the cylinder mouth part; the cylinder mouth part is a multi-layer plate; and the bearing plates are separately arranged at the cylinder cover bolt tack hole parts and used for adjusting the whole surface pressure of the air cylinder cover gasket. According to the air cylinder cover gasket, the cylinder mouth part and the cylinder cover bolt tack hole parts of the air cylinder cover gasket are separately designed, so that sealing of an air cylinder is ensured, a material is saved, and the air cylinder cover gasket is environment-friendly.
Description
Technical field
The present invention relates to engine cylinder field, particularly a kind of cylinder head gasket.
Background technique
Cylinder head gasket, is called for short cylinder pad, is the elastic sealing elements being placed between cylinder block and head.Due to can not be definitely smooth between cylinder body and cylinder cap, therefore, just need to there is cylinder head gasket to prevent that pressurized gas, lubricant oil and cooling water are from scurrying out between them.Along with the development of engine technology, at present large multiple-motor adopts the cylinder head gasket of the metallic material of multilayer (2 layers or more multi-layered), this scheme can realize the effective sealing of cylinder inner high voltage gas, and because metal framework entirety adopts stacked conducting plate, so, the face of cylinder head gasket is pressed comparatively even, and the reliability of cylinder head gasket is better.
As shown in Figures 1 and 2, the integral frame of existing cylinder head gasket 10 is multi-layer sealing structure design, the cylinder notch portion 101 of existing cylinder head gasket 10 and cylinder bolt are crossed nail bore portion 102 and frame body and are belonged to the identical sealing number of plies (referring to Fig. 2), and metal framework entirety adopts stacked conducting plate, this design can meet the sealing effect of cylinder block, but consumptive material is many, cost is high.
Therefore, cylinder head gasket metal framework entirety of the prior art adopts stacked conducting plate, and consumptive material is many, and cost is high, can not save material.
Summary of the invention
The present invention is in order to overcome defect in above-mentioned prior art, and a kind of cylinder head gasket is provided, and crosses nail bore portion design separately by the cylinder notch portion to cylinder head gasket and cylinder bolt, can save material, reduces costs.
For achieving the above object, the invention provides a kind of cylinder head gasket, comprising: frame body, it has cylinder notch portion and cylinder bolt is crossed nail bore portion, and frame body is removed cylinder oral area and is divided into single layer board, and cylinder oral area is divided into sandwich plate; And bearing plate, it is located at separately cylinder bolt and crosses the integral face that nail bore portion is used for adjusting cylinder head gasket and press.
In technique scheme, frame body is removed cylinder oral area and is divided into single-layer metal plate, and cylinder oral area is divided into stacked conducting plate.
In technique scheme, the material of bearing plate and frame body is stainless steel.
In technique scheme, cylinder oral area is divided into 3-4 layer sheet metal.
Compared with prior art, the present invention has following beneficial effect: by the cylinder notch portion to cylinder head gasket and cylinder bolt, cross nail bore portion and design separately, and the frame body of cylinder head gasket is removed cylinder oral area and is divided into single layer structure, when guaranteeing cylinder seal, save material, use environmental protection.
Accompanying drawing explanation
Fig. 1 is existing cylinder head gasket structural representation;
Fig. 2 is the partial sectional view along A-A direction in Fig. 1;
Fig. 3 is cylinder head gasket structural representation of the present invention;
Fig. 4 is the partial sectional view along B-B direction in Fig. 3.
Mark the following drawings mark thereon by reference to the accompanying drawings:
1-frame body, 11-cylinder notch portion, 12-cylinder bolt is crossed nail bore portion, 2-bearing plate.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of embodiment.
Cylinder head gasket of the present invention needs difference according to frame body in the sealing of different parts, by designing the single-store frame body that is divided into multi-layer sealing structure except cylinder oral area, under the prerequisite of sealing function that guarantees cylinder head gasket, can save consumptive material.
As shown in Figures 3 and 4, the cylinder head gasket that the present embodiment provides comprises frame body 1 and bearing plate 2, frame body 1 has cylinder notch portion 11 and cylinder bolt is crossed nail bore portion 12, frame body 1 entirety adopts sheet metal to make, but cylinder notch portion 11 adopts stacked conducting plate, be generally designed to 3-4 layer, other parts of removing outside cylinder notch portion are single-layer metal plate, specifically can adopt stainless steel.Even in order to realize the pressure-bearing surface of gland shim, at the cylinder bolt of cylinder head gasket, cross nail bore portion 12 and be provided with separately bearing plate 2, the different parts that the design consideration cylinder bolt of bearing plate 2 is crossed nail hole designs different shapes, as long as can guarantee stress surface smooth of cylinder head gasket, can adjust cylinder head gasket integral face and press.Bearing plate 2 can adopt the material that is different from frame body 1 to make, such as adopting common stainless steel, also can adopt the material same with cylinder notch portion to make, the bearing plate 2 of making separately can be fixed on and be needed position by the mode of welding, when using this cylinder head gasket, make equally cylinder seal like this, but can save the material at frame body 1 other positions, and use environmental protection.
Disclosed is above only specific embodiments of the invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
