Description
Technical field
The present invention relates to gasket seal technical fields, more particularly to a kind of cylinder head cover gasket.
Background technique
Cylinder Cover Gasket, abbreviation cylinder pad are the elastic sealing elements being placed between cylinder block and head.Due to
Can not be absolutely smooth between cylinder body and cylinder cap, it is therefore desirable to have cylinder head gasket to prevent high pressure gas, lubricating oil and cold
But water is scurried out between them.There are two types of cylinder-top gaskets: using asbestos as matrix, outsourcing copper sheet or sheetmetal, and some braided steel wires
Or rolling hole steel plate is skeleton, some adds becket around cylinder holes, and to improve intensity, advantage is that price is lower, but intensity is poor；
It is made of the steel plate of monolithic finishing, the flexible burr at sealing, is sealed by the elasticity of burr and the effect of temperature resistant encapsulation glue,
Advantage is intensity height, and sealing effect is good, but higher cost.
In actual conditions, since the combustion chamber sealing spot temperature of engine is higher, gasket seal in existing cylinder head
It is easily damaged at high temperature and pressure, gasket seal periphery is caused to fester and separate, cause stress value reduction, generate engine oil
Dew, but there is no warning notes for whole process, there are security risks；Sometimes gasket can be loose because of the high-frequency vibration of engine
It is dynamic, it causes to generate gap between cylinder head cover and cylinder.
Summary of the invention
(1) the technical issues of solving
Present invention aims to overcome that the shortcomings that above-mentioned prior art, provide a kind of cylinder head cover gasket.
(2) technical solution
A kind of cylinder head cover gasket, including gasket I, sheet rubber, gasket II and protective layer, the gasket I, sheet rubber and gasket
II sets gradually from top to bottom, and the protective layer is arranged on the whole right side that gasket I, sheet rubber and gasket II form；
The inside of the gasket I is equipped with pressure sensor piece, and the pressure sensor piece is connected in ECU control unit by conducting wire, described
ECU control unit is connected with alarm lamp；Gap is equipped between the sheet rubber and gasket II, the inside of the sheet rubber is equipped with sky
Chamber is equipped with friction plate group in the cavity, and the friction plate group includes 2 friction plates, and cavity is respectively set in the friction plate
The left and right sides, described friction plate one end are fixed on the inner wall of cavity, and the other end is free end, the free end of the friction plate
Divide and be overlapped setting, the bottom surface of the cavity is equipped with venthole, and the venthole is connected with air bag, and the air bag is arranged in gap
In.
Further, the protective layer is set as ceramic metal alloy layer.
Further, the quantity of the cavity is at least provided with two.
Further, nitrogen is equipped in the cavity.
Further, the quantity of the friction plate group is at least provided with two groups, and the friction plate group is between the upper and lower every setting.
Further, the air bag is set as high-temperature resistant rubber air bag.
(3) beneficial effect
A kind of cylinder head cover gasket provided by the invention, due to that constantly vibration can cause to connect bolt in cylinder start-up course
Loosening after pressure sensor piece receives signal, it is single to pass to ECU control so that the pressing force between cylinder head cover and cylinder decays
Member issues alarm signal, makes corresponding processing mode convenient for people；The vibration of cylinder can make the mutual friction of friction plate phase and generate
Heat, air expansion cause air bag to expand, and then make to be bonded closer, reinforcement sealing effect between gasket and cylinder head cover, anti-
Only sealing effect is bad, causes leakage and influences the normal performance of engine power.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, will be described below to embodiment required
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description be only it is of the invention, protect some embodiments, it is right
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings
His attached drawing.
Fig. 1 is the structural diagram of the present invention；
In attached drawing, parts list represented by the reference numerals are as follows:
1- gasket I, 2- sheet rubber, 3- gasket II, the gap 4-, 5- cavity, 6- friction plate group, 7- protective layer, 8- air bag, 9-
Pressure sensor piece, 10- venthole.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of cylinder head cover gasket, including gasket I 1, sheet rubber 2, gasket II 3 and protective layer 7, gasket I 1,
Sheet rubber 2 and gasket II 3 are set gradually from top to bottom, and the whole of gasket I 1, sheet rubber 2 and the composition of gasket II 3 is arranged in protective layer 7
On the right side of body, and the inside of cylinder head cover is arranged in protective layer 7；The inside of gasket I 1 is equipped with pressure sensor piece 9, feeling of stress
Piece 9 is answered to be connected in ECU control unit by conducting wire, ECU control unit is connected with alarm lamp；Between sheet rubber 2 and gasket II
Equipped with gap 4, the inside of sheet rubber 2 is equipped with cavity 5, and friction plate group 6 is equipped in cavity 5, and friction plate group 6 includes 2 friction plates,
The left and right sides of cavity 5 is respectively set in friction plate, and friction plate one end is fixed on the inner wall of cavity 5, and the other end is free end, rubs
The free end portion of pad is overlapped setting, adequacy when convenient for phase mutual friction, and the bottom surface of cavity 5 is equipped with venthole 10, ventilation
Hole 10 is connected with air bag 8, and air bag 8 is arranged in gap 4.
Further, protective layer 7 is set as ceramic metal alloy layer.
Further, the quantity of cavity 5 is at least provided with two.
Further, nitrogen is equipped in cavity 5.
Further, the quantity of friction plate group 6 is at least provided with two groups, and friction plate group 6 is between the upper and lower every setting.
Further, air bag 8 is set as high-temperature resistant rubber air bag.
The course of work of the invention is installed the present invention between cylinder head cover and cylinder, with the work of cylinder, can not be stopped
Ground generates vibration, and the process of vibration can make the friction plate group 7 in cavity 5 interact, i.e., every group of friction plate phase mutual friction, by
Heat can be generated in friction, increases the internal temperature in cavity 5, nitrogen expanded by heating, air bag 8 is to seal to connect with venthole 10
It connects, so the nitrogen of expansion can be such that air bag 8 also expands therewith, and acts on gasket II 3, and then keep gasket gentle with cylinder head cover
Cylinder is snugly closer, improves the sealing effect of gasket；Gasket I 1, sheet rubber 2 and II 3 long-time of gasket are soaked by high temperature oil
Bubble, it may appear that the periphery of gasket seal is festered and is separated, so that the pressure value for acting on cylinder head cover on gasket I 1 reduces,
After pressure sensor piece receives the signal that pressure value reduces, ECU control unit is passed to, and then issue alarm signal, notify car owner
There is exception in cylinder cover of engine, need on-call maintenance, avoid security risk.
