Technical field
It the utility model is related to auto parts and components field, and in particular to a kind of reusable exhaust manifold gasket.
Background technology
Exhaust manifold, it is connected with engine cylinder block, the exhaust of each cylinder is put together into importing exhaust main, carried
The pipeline of difference.The automobile engine of early stage, the power of Unit Weight is low, and the efficiency of combustion of fuel is not high, the waste gas discharged
Temperature is no more than 500 DEG C.With the raising of car engine engine efficiency, delivery temperature brings up to 600~650 DEG C.In recent years, constantly
Improve automobile exhaust emission standard, catalysis technique and worm gear supercharging technology using the more notable work for improving exhaust manifold
Temperature, more than 750 DEG C are reached.With the further raising of engine performance, the operating temperature of exhaust manifold will also improve.With
This simultaneously, with the progress of engine technology, the structure of exhaust manifold also complicates therewith, in addition in repeat state of temperature
Lower work, it is desirable to which exhaust manifold material will not only have good high-temperature behavior, also possess good casting character.
Therefore exhaust manifold must possess following characteristic:1st, good high-temperature oxidation resistance:Exhaust manifold is for a long time in height
Worked under warm repeat state, the antioxygenic property of material at high temperature directly influences the service life of exhaust manifold.It is general
Logical cast iron obviously can not meet requirement, it is necessary to add the high-temperature oxidation resistance that alloying element improves material in the material;2nd, it is steady
Fixed microscopic structure:In room temperature to operating temperature range, material should not undergo phase transition or reduce as far as possible phase transformation as far as possible.Because
Phase transformation can cause the change of volume, be allowed to produce internal stress or deformation, influence performance and the life-span of product.Therefore matrix material
Material preferably stable ferrite or austenite structure.The failure mode of the cast iron part to work under the high temperature conditions mainly shows
For the corrosion under hot conditions, after the composition phase oxidation in tissue, such as graphitic carbon, the volume of oxide is more than original volume, drawn
Play the irreversible expansion of casting;3rd, thermal coefficient of expansion is small:Small thermal coefficient of expansion be advantageous to reduce exhaust manifold thermal stress and
Thermal deformation, be advantageous to improve the performance and service life of product;4th, excellent elevated temperature strength:Product must is fulfilled in high temperature
Necessary intensity requirement during lower use;5th, good processing performance and low cost:It is heat-resisting, refractory metal material species is a lot,
But for the shape that exhaust manifold is complicated, the material for manufacturing exhaust manifold must have a good manufacturability, and its into
Originally it must is fulfilled for the demand of auto industry batch production.
In order to ensure exhaust manifold exhaust sealing it is intact, and avoid exhaust manifold during engine use with
Loosened between cylinder, influence the normal importing of exhaust, exhaust is then installed between exhaust manifold and cylinder
Manifold gasket, but because traditional exhaust manifold gasket is a very thin pad, cause exhaust manifold to be used in the later stage
When, poor sealing, it is easy to which the waste gas for causing inblock cylinder to remove leaks, after engine long-term use, it is easy to be vented
Manifold loosens, and influences the normal use of exhaust manifold and the normal work of engine.Simultaneously as exhaust manifold gasket is in high temperature
Worked under environment, it is thermally stressed, easily produce thermal deformation, and then the binding face of exhaust manifold gasket and exhaust manifold exhaust end
Out-of-flatness, and then cause seal failure.

For connecting portion in the both ends of the Upper gasket and lower gasket, the Upper gasket, lower gasket and elastic joint part form cavity, described
Heat dissipation element is provided with cavity, compared to existing chip exhaust manifold gasket, the exhaust manifold gasket body of cavity body structure
Because both ends use elastic joint part, when exhaust manifold and cylinder vibrations or dislocation, Upper gasket and lower gasket exist
It can automatically adjust in the presence of elastic joint part, be bonded with exhaust manifold with cylinder, avoid exhaust manifold gasket sheet
Larger space is produced between body and exhaust manifold or cylinder, causes seal failure;Cavity body structure also causes exhaust manifold
Gasket body radiating effect itself is more preferable, meanwhile, the effect of heat dissipation element is also beneficial to the radiating of exhaust manifold gasket body, keeps away
It is too high and cause exhaust manifold gasket body to produce thermal deformation to exempt from temperature, and then causes seal failure.
Further, be additionally provided with flexible member one in the cavity, the both ends of flexible member one respectively with the upper pad
Piece is connected with lower gasket, when the Upper gasket and lower gasket of exhaust manifold gasket body are by greater impact power, flexible member one
Buffering and damping can be played a part of.
Further, flexible member two is provided between the heat dissipation element and the Upper gasket and lower gasket, is passed through
Heat dissipation element is connected by flexible member two with Upper gasket and lower gasket, when Upper gasket and lower gasket automatic adjusting position, radiating member
Part can also automatically adjust, and avoid heat dissipation element from being damaged, and extend the service life of exhaust manifold gasket body.
Further, the elastic joint part uses high temperature resistant elastomeric material.
Further, the heat dissipation element is fin.
Further, the flexible member one is spring.
Further, the flexible member two uses high temperature resistant elastomeric material, above-mentioned high temperature resistant elastomeric material, fin and

Machine cylinder is bonded, and is avoided producing larger space between exhaust manifold gasket body and exhaust manifold or cylinder, is caused close
Envelope failure.
2nd, a kind of reusable exhaust manifold gasket of the utility model, cavity body structure also cause exhaust manifold gasket sheet
Body radiating effect itself is more preferable, meanwhile, the effect of heat dissipation element is also beneficial to the radiating of exhaust manifold gasket body, avoids temperature
It is too high and cause exhaust manifold gasket body to produce thermal deformation, and then cause seal failure.
3rd, a kind of reusable exhaust manifold gasket of the utility model, flexible member is additionally provided with the cavity
One, the both ends of flexible member one are connected with the Upper gasket and lower gasket respectively, when exhaust manifold gasket body Upper gasket and
When lower gasket is by greater impact power, flexible member one can play a part of buffering and damping, extend exhaust manifold gasket
