Description
Technical field
This utility model relates to engine art, particularly to the cylinder head gasket of a kind of electromotor.
Background technology
As it is shown in figure 1, cylinder head gasket 2 is pressed between cylinder jacket 1, cylinder block 4 and cylinder head 3.In prior art,
Cylinder head gasket 2 is multi-layer metal structure, it include multiple be from top to bottom sequentially placed envelope qigong ergosphere 21, be disposed therein
Distance layer 220 between two adjacent envelope qigong ergospheres 21 and spacing layer 230, the effect of distance layer 220 and spacing layer 230 is
Adjust the thickness of cylinder head gasket 2.Envelope qigong ergosphere 21 is provided with multiple groove 211 or projection, makes envelope qigong ergosphere 21 be formed
Corrugated.After having assembled, the envelope qigong ergosphere 21 of the top directly contacts the bottom surface of cylinder head 3.
When the rigidity deficiency of cylinder head 3, operationally, cylinder head 3 can send out the effect of pressure to electromotor at cylindrical implosion
The most constantly by jack-up and falling, the bottom surface of cylinder head 3 " is directly hit with the groove or projection sealing qigong ergosphere 21 in the process
Hit " and be gradually worn, easily cause and rush cylinder pad, even have no alternative but because of the bottom surface excessive wear of cylinder head 3 change cylinder head
3。
The information being disclosed in this background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or imply in any form this information structure existing well known to persons skilled in the art
Technology.
Utility model content
The purpose of this utility model is to provide the cylinder head gasket of a kind of electromotor, thus overcomes existing cylinder-top gasket
Sheet easily makes the shortcoming that cylinder head is worn and torn.
For achieving the above object, this utility model provides the cylinder head gasket of a kind of electromotor, and cylinder head gasket is arranged
In the space that cylinder block, cylinder head and the cylinder jacket of electromotor surround, cylinder head gasket includes: protective layer, and protective layer supports
Being connected on the bottom surface of cylinder head, protective layer is tabular；Multiple envelope qigong ergospheres, multiple envelope qigong ergospheres set the most successively
Putting the lower section at protective layer, multiple envelope qigong ergospheres are provided with multiple groove or projection, make envelope qigong ergosphere form corrugated；Limit
Position layer, spacing layer is arranged between adjacent envelope qigong ergosphere, makes cylinder head gasket have predetermined thickness.
Preferably, in technique scheme, spacing layer is arranged on the top of the envelope qigong ergosphere of bottom.
Preferably, in technique scheme, protective layer, envelope qigong ergosphere and spacing layer are made up of steel spring plate.
Compared with prior art, this utility model has the advantages that
This utility model is provided with smooth protective layer between cylinder head and envelope qigong ergosphere, it is to avoid cylinder head is falling
During with envelope qigong ergosphere ripple clash into cause the bottom surface of cylinder head to be worn, extend the life-span of cylinder head.
Accompanying drawing explanation
Fig. 1 is cylinder head gasket and cylinder block and the installation diagram of cylinder jacket of the electromotor of prior art.
Fig. 2 is the cylinder head gasket according to electromotor of the present utility model and cylinder block and the installation diagram of cylinder jacket.
Main Reference Numerals illustrates:
1-cylinder jacket, 2-cylinder head gasket, 21-seals qigong ergosphere, 211-groove, 22-protective layer, 220-distance layer, 23-
Spacing layer, the spacing layer of 230-, 3-cylinder head, 4-cylinder block.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described in detail, it is to be understood that this practicality
Novel protection domain is not limited by detailed description of the invention.
Explicitly indicating that unless otherwise other, otherwise in entire disclosure and claims, term " includes " or it becomes
Change and such as " comprising " or " including " etc. will be understood to comprise stated element or ingredient, and do not get rid of other yuan
Part or other ingredient.
As in figure 2 it is shown, include protective layer according to the cylinder head gasket 2 of the electromotor of this utility model detailed description of the invention
22, multiple envelope qigong ergospheres 21 and spacing layer 23.Protective layer 22, envelope qigong ergosphere 21 and spacing layer 23 are by steel spring plate system
Become.
Protective layer 22 is in tabular, and it is arranged on the bottom surface of cylinder head 3, directly contacts with the bottom surface of cylinder head 3, right
The bottom surface of cylinder head 3 plays a protective role.
Envelope qigong ergosphere 21 is provided with multiple groove 211 or projection, makes envelope qigong ergosphere 21 form corrugated.Multiple envelope gas
Functional layer 21 is from top to bottom successively set on the lower section of protective layer 22 so that the position of the groove of envelope qigong ergosphere 21 is with adjacent
The protruding correspondence of envelope qigong ergosphere, plays the function of envelope gas.
Spacing layer 23 is arranged between adjacent two envelope qigong ergospheres 21, and it plays the work of the thickness regulating cylinder head gasket
With so that cylinder head gasket keeps the predetermined thickness of this type, makes the envelope gas part thickness of cylinder head gasket more than oil sealing, water shutoff
The thickness at position, makes the axle power of cylinder bolt focus more on envelope gas position.As an embodiment, as in figure 2 it is shown, spacing layer 23
It is arranged on the top of the envelope qigong ergosphere 21 of bottom.
When the rigidity deficiency of cylinder head 3, operationally, cylinder head 3 is under cylindrical implosion sends out the effect of pressure to electromotor
Constantly by jack-up and falling, owing to cylinder head 3 is kept apart by protective layer 22 with envelope qigong ergosphere 21, cylinder head 3 jack-up with
In dropping process, the bottom surface of cylinder head 3 is clashed into the flat top of protective layer 22, without clashing into the ripple of envelope qigong ergosphere,
Therefore the bottom surface of cylinder head 3 will not produce abrasion.
This utility model is provided with smooth protective layer between cylinder head and envelope qigong ergosphere, it is to avoid cylinder head is falling
During with envelope qigong ergosphere ripple clash into cause the bottom surface of cylinder head to be worn, extend the life-span of cylinder head.
The aforementioned description to specific illustrative embodiment of the present utility model illustrates that and the purpose of illustration.These
Describe and be not wishing to be defined to this utility model disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
A lot of changes and change.The purpose selected exemplary embodiment and describe is to explain certain principles of the present utility model
And reality application, so that those skilled in the art is capable of and utilizes various different example of the present utility model
Property embodiment and various different selection and change.Scope of the present utility model be intended to by claims and etc. similar shape
Formula is limited.
