Abstract
The invention discloses an exhaust manifold spacer with the surface coated with a high-temperature antifriction coating. The exhaust manifold spacer comprises a sealing spacer body, the high-temperature antifriction coating and a stainless steel base layer. The sealing spacer body is composed of the high-temperature antifriction coating and the stainless steel base layer. The high-temperature antifriction coating is sprayed to the surface of the stainless steel base layer. According to the exhaust manifold spacer with the surface coated with the high-temperature antifriction coating, the surface of the sealing spacer body is coated with high-temperature antifriction paint, a thermal insulation medium is formed between the sealing spacer body and a flange, thermal energy conduction is reduced, and the sealing spacer body is protected; tiny knife grains of the flange surface can be filled with the paint, and a micro-sealing function is achieved; and molybdenum disulfide of the proper proportion is added in the paint, a lubricating film can be formed between the sealing spacer body and the flange, relative friction force generated by expansion and contraction of the flange and the spacer is reduced, and good sealing performance can also be guaranteed when the spacer is in the ultrahigh-temperature environment.
Description
Technical field
The present invention relates to technical field of automobile parts, specially a kind of exhaust manifold of surface spraying high-temperature antifriction coating
Pad.
Background technology
Gas extraction system refers to connect the air vent of combustor, via exhaust manifold and exhaustor rear by waste gas discharge, and
The lower noise that the waste gas discharge of high temperature and high pressure is produced.If exhaustor cannot arrange rapidly the waste gas after photocombustion, air inlet
Also relatively fresh air cannot be fully entrained；Remain in the indoor waste gas of burning, it will have influence on burning effect next time this moment
Can, consequently, it is possible to the power of electromotor can be affected.At first through exhaust manifold during waste gas discharge, exhaust manifold is in design
On above all avoid the aerofluxuss between each cylinder to interfere, make waste gas be completely exhausted out pipe as much as possible outer.In order to ensure to arrange
Gas manifold discharges the situation occurring without gas leakage in exhaust process, is provided with exhaust manifold gasket on exhaust manifold.
Turbocharged engine exhaust manifold part temperature is typically very high to can reach 900 DEG C～1030 DEG C, the heat of flange face
Expand and contraction all ratios are larger, common exhaust manifold gasket easily damages under such conditions and lost efficacy, and pad weakness is hermetically
Side is possible to send out gas leak phenomenon, and the overall performance of impact electromotor even reduces the service life of electromotor.
Content of the invention
It is an object of the invention to provide a kind of exhaust manifold gasket of surface spraying high-temperature antifriction coating, above-mentioned to solve
The exhaust manifold gasket of the prior art proposing in background technology thermal expansion at high operating temperatures is larger with contraction, easily damages
The bad problem losing efficacy.
For achieving the above object, the present invention provides a kind of following technical scheme: aerofluxuss of surface spraying high-temperature antifriction coating
Manifold gasket, including gasket seal body, high-temperature antifriction coating and rustless steel bottom, described gasket seal body is by high-temperature antifriction
Coating and rustless steel bottom are constituted, and described high-temperature antifriction coating spraying is in the surface of rustless steel bottom.
Preferably, described high-temperature antifriction coating adopts aqueouss molybdenum bisuphide self-lubricating antifriction coating.
Compared with prior art, the invention has the beneficial effects as follows: the exhaust manifold pad of this surface spraying high-temperature antifriction coating
Piece passes through in sealing gasket surface-coated high-temperature antifriction coating, forms a kind of insulation medium between sealing gasket and flange, reduces heat
Can conduct and protect sealing gasket；The small knife mark that coating itself can fill flange face plays microsealing effect；Add in coating
Added with the molybdenum bisuphide of proper proportion, one layer of lubricating film can be formed between sealing gasket and flange, reduce flange and pad because
Expand and shrink the relative friction forces producing, so that pad also ensure that good sealing in the environment of superhigh temperature
Energy.
Brief description
Fig. 1 is present configuration schematic diagram；
Fig. 2 is a-a sectional view of the present invention.
In figure: 1, gasket seal body, 2, high-temperature antifriction coating, 3, rustless steel bottom.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Refer to Fig. 1-2, the present invention provides a kind of a kind of technical scheme: exhaust manifold of surface spraying high-temperature antifriction coating
Pad, including gasket seal body 1, high-temperature antifriction coating 2 and rustless steel bottom 3 it is characterised in that: gasket seal body 1 by
High-temperature antifriction coating 2 and rustless steel bottom 3 are constituted, and high-temperature antifriction coating 2 is sprayed at the surface of rustless steel bottom 3.
In above-described embodiment, specifically, high-temperature antifriction coating 2 adopts aqueouss molybdenum bisuphide self-lubricating antifriction coating, coating
In be added with molybdenum bisuphide, can form one layer of lubricating film between sealing gasket and flange, reduce flange and pad because expanding and
Shrink the relative friction forces producing.
Operation principle: in the exhaust manifold gasket using this surface spraying high-temperature antifriction coating, need first to whole table
The exhaust manifold gasket of face spraying high temperature friction coat has the understanding in a structure, the row of this surface spraying high-temperature antifriction coating
The main production of gas manifold gasket is gasket seal body punching press → cleaning → spraying, and rustless steel bottom 3 is by punching press
Become, high-temperature antifriction coating 2 is passed through spraying and is attached to the surface of rustless steel bottom 3, rustless steel bottom 3 surface formed one layer thin
Protecting film, after gasket seal body 1 is assembled to flange, high-temperature antifriction coating 2 can fill the trickle knife mark gap of flange surface
Play microsealing effect, be added with molybdenum bisuphide in high-temperature antifriction coating 2, there is high temperature resistant and antifriction function, high temperature subtracts simultaneously
Coating of rubbing 2 can form adiabatic membrane between flange and gasket seal body 1, reduces the heat biography to gasket seal body 1 for the flange
Lead, reduce the frictional force between gasket seal body 1 and flange, thus reaching the effect of protection gasket seal body 1.
In sum, the basic principles, principal features and advantages of the present invention have been shown and described above.The technology of the industry
, it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and description is originally for personnel
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and its
Effect thing defines.
