Abstract
The invention discloses a cylinder head gasket with a variable step of a cylinder port. The cylinder head gasket comprises a cylinder gasket body (1), wherein at least one cylinder hole (2) is arranged in the cylinder gasket body, and the cylinder gasket body (1) is composed of metal sheets; and each layer of metal sheet is in an opening form (7) at the edge of the cylinder hole (2). The cylinder head gasket is characterized in that gas sealing corrugations are pressed on the two layers of metal sheets at the periphery of the cylinder hole (2); and a cylinder port ring (8) and an adjustment plate (9) are arranged between the two layers of metal sheets, the thickness of one layer of cylinder port ring (8) is adjusted, the periphery of the cylinder hole (2) is thicker than other positions, the thickness difference between the cylinder port ring (8) and the adjustment plate (9) forms a step structure of the cylinder port, and the cylinder port ring (8) forming the step of the cylinder port is machined into different thicknesses through a die along the circumferential direction, and is matched with the sealing corrugations to play a role of gas sealing for the cylinder port. The problem of different sealing pressures caused by different deformations of the periphery of the cylinder hole of an engine is overcome, and a uniform sealing pressure of the periphery of the cylinder hole is guaranteed.
Description
Technical field：
The present invention relates to engine cylinder cap pad technical field, specifically a kind of variable cylinder mouth segment difference cylinder head gasket.
Background technology：
Cylinder head gasket is mounted in the seal member between cylinder head and cylinder block, its role is to reliably seal high temperature combustion
Gas, lubricating oil and coolant, prevent from revealing, and its middle cylinder mouth envelope gas is crucial, and the quality of cylinder head gasket directly affects starts
The performance of machine.
As shown in fig. 1, this cylinder head gasket cylinder mouth segment difference is along the circumferential direction common engine cylinder head pad
Identical.At present, with the development of engine technology, electromotor develops to densification, light-weighted direction, electromotor simultaneously
The continuous lifting of energy, explosion pressure also more and more higher, for guaranteeing the reliability of cylinder mouth envelope gas, general method is to improve cylinder mouth section
Difference, to improve cylinder oral area position seal pressure, because engine body, cylinder cap cylinder oral area position deform difference everywhere, therefore in deformation
Can there are local weak spots in big position, only improve cylinder oral area position segment difference and air seal can not be completely secured, cylinder mouth segment difference mistake simultaneously
Conference aggravation engine body, cylinder cap deformation, adversely affect to electromotor.Invent a kind of cylinder-top gasket of variable cylinder mouth segment difference
Piece, makes that cylinder oral area position seal pressure is more uniform, and to meet electromotor seal request, tool is of great significance.
Content of the invention：
The purpose of the present invention is to overcome the shortcomings of above-mentioned prior art, and provides a kind of variable cylinder mouth segment difference cylinder head gasket；Main
Solve the problems, such as that existing cylinder head gasket can have local weak spots at the big position of deformation.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of variable cylinder mouth segment difference cylinder head gasket, including
Cylinder pad body（1）, described cylinder pad body is provided with least one cylinder-bore（2）, cylinder-bore（2）Run through cylinder pad body up and down
（1）, described cylinder pad body（1）It is made up of sheet metal；Every layer of sheet metal is in cylinder-bore（2）The position at edge is in opening form
（7）；It is characterized in that, described sheet metal is in cylinder-bore（2）Air seal ripple is suppressed on the double layer of metal thin plate of surrounding；?
There is cylinder choma between double layer of metal thin plate（8）With adjustment plate（9）, adjust wherein one layer cylinder choma（8）Thickness, cylinder-bore（2）Around
Thicker than other positions, cylinder choma（8）With adjustment plate（9）Thickness difference formed cylinder mouth segment difference structure, described formation cylinder mouth segment difference
Cylinder choma（8）, it is processed into different thickness in circumferential direction through mould.
Compared with the prior art a kind of variable cylinder mouth segment difference cylinder head gasket of the present invention has prominent substance
Feature and marked improvement：
1st, pass through to adjust the thickness of one layer of cylinder choma of cylinder pad body, more thick than other positions around cylinder-bore, form cylinder mouth section
Difference structure, forms the cylinder choma of cylinder mouth segment difference, needs to be processed into different thickness in circumferential direction through mould according to sealing, with
Sealing ripple cooperation, plays the function that cylinder mouth seals gas, has been obviously improved reliability and the durability of cylinder head gasket air seal；
2. cylinder-top gasket chip architecture is simple, easy to use, long service life, good sealing effect；Require to carry in electromotor detonation pressure etc.
In the case of height, can effectively guarantee air seal, can ensure that reliability and service life get a promotion again.

Specific embodiment：
Below in conjunction with accompanying drawing, the present invention will be described in detail, and illustrated embodiment is served only for explaining the present invention, is not intended to limit
Determine the scope of the present invention.
Embodiment 1, referring to Fig. 2,3,4, is processed into cylinder pad body 1 according to design requirement, is provided with cylinder pad body 1
Several cylinder-bore 2, cylinder-bore runs through cylinder pad body 1 about 2, if cylinder pad body 1 is made up of dried layer sheet metal, cylinder-bore 2
Surrounding has double layer of metal thin plate, and that is, two-layer is suppressed with the upper pressure ripple plate of air seal ripple 5 and lower air seal ripple 6 respectively
3 and push ripple plate 4；Upper pressure ripple plate 3 and pushing has cylinder choma 8 and adjustment plate 9 between ripple plate 4；Three-layer metal around cylinder-bore 2
Leave gap between thin plate and form opening form 7；By adjusting cylinder choma 8 thickness, cylinder-bore 2 surrounding is thicker than other positions, cylinder
Choma 8 forms cylinder mouth segment difference structure with the thickness difference of adjustment plate 9, forms the cylinder choma 8 of cylinder mouth segment difference, in circumferential direction through mould
Tool is processed into different thickness, and the thickness of cylinder choma shown in Fig. 48 is more than the thickness of cylinder choma 8 shown in Fig. 3, forms variable segment difference,
With the cooperation of air seal ripple, play the function that cylinder mouth seals gas.
Above-described embodiment 1, air seal ripple and cylinder mouth segment difference folded structures；Fig. 4 middle cylinder choma 8 thickness is more than in Fig. 3
Cylinder choma 8 thickness, can suppress overpressure, the pressure of supplementary pressure lower position, so that one week seal pressure of cylinder mouth is more
Plus uniformly.
The cylinder head gasket of a kind of variable cylinder mouth segment difference that the present invention provides, by the variable segment difference of cylinder mouth and air seal ripple
The cooperation of stricture of vagina, plays the function that cylinder mouth seals gas.
The invention has the beneficial effects as follows while guaranteeing cylinder head gasket air seal effect, by variable segment difference, just
It is possible to rigidity according to electromotor to adjust face pressure, sealing can be improved and reduce the deformation of electromotor.
