Abstract
A kind of novel belt supports high-intensity sealing pad, is related to engine and manufactures and designs field, section is T-shaped, including pad and flange, and the flange is vertical with the pad affixed；Being horizontally disposed with the pad has metal transversum, and metal is vertically arranged with the flange and erects bone, the metal transversum and the perpendicular bone of the metal are vertical affixed.The intensity of sealing gasket is improved by increasing skeleton filling in rubber, so as to improve the anti-pressure ability of sealing, can both meet seal request, improve the service life of sealing gasket again.
Description
Technical field
It the utility model is related to engine and manufacture and design field, and in particular to a kind of novel belt supports high-intensity sealing pad.
Background technology
Cylinder head cover sealing gasket (abbreviation sealing gasket) is the sealing gasket being placed between cylinder head and valve mechanism cover.Cylinder head
The effect of hood seal gasket is to prevent gas blowby and sputter the lubricating oil come between cylinder head and valve mechanism cover from camshaft bearing
Let out, its principle is that compression counter-force is made caused by sealing gasket when sealing gasket is by housing and the vertical compression force deformation of cylinder body
For housing and cylinder body, so as to play sealing function.
As Chinese Automobile Industry ' rapidly develops, auto Parts Industry also steps into the high-speed developing period together.At a high speed,
Requirement more and more higher of the development of big power engine to each side of engine；Parts are in continuous flow procedure to high
Efficiency of assembling and accordance require also more and more higher；Meanwhile as Environmental protects desired continuous improvement, it is green, low
The requirement of carbon, no pollution also proposes higher standard to engine cylinder head cover sealing gasket.
The premise for improving engine power is pressure in increase cylinder, and the sealing gasket of gum is difficult to meet to seal accordingly
Requirement.When cylinder head cover sealing gasket fails, the performance and normal work of engine will be directly affected.When cylinder high temperature rushes
During pressure, the easy outside torsional deformation of existing sealing gasket stress, so as to penetrate into the gap between sealing gasket and housing, final leakage.
The content of the invention
In order to solve the technical problem of intensity deficiency caused by pressure increase in above-mentioned existing cylinder, the utility model carries
For a kind of novel high-strength sealing gasket, the intensity of sealing gasket is improved by increasing skeleton filling in rubber, it is close so as to improve
The anti-pressure ability of envelope, can both meet seal request, improve the service life of sealing gasket again.
The purpose of this utility model can be realized by following technical proposal：A kind of novel high-strength sealing gasket, section are in T
Type, including pad and flange, the flange are vertical with the pad affixed；Being horizontally disposed with the pad has metal transversum, institute
State and the perpendicular bone of metal is vertically arranged with flange, it is vertical affixed that the metal transversum and the metal erect bone.
According to the utility model, the metal transversum can not only avoid pad excess compression when cylinder assembles, and ensure
When sealing reaction force, and can be rushed outside the high-temperature oil gas burning of cylinder, bone is erected by metal and improves flange lateral rigidity,
Weaken sealing gasket deformation.
Preferably, in the flange, the metal erects bone side and is fixedly connected with leaf spring.It is furthermore preferred that the leaf spring
It is arranged with parallel multigroup, and is bent downwardly.
It is furthermore preferred that sealing gasket is in a ring, the leaf spring is arranged in the flange on the outside of sealing gasket.It is new according to this
Type, the leaf spring can ensure sealing gasket toughness, and can increase flange stiffness, it is anti-to improve compression in flange side loaded
Active force, it is ensured that outer side seal is bonded.
Preferably, the pad top surface is alternate is provided with oil groove and rib, and the rib gradient on the outside of the sealing gasket is less than
The rib gradient on the inside of the sealing gasket.The oblique rib can further increase the lateral rigidity of sealing gasket, it is ensured that close
Sealing intensity of the packing in high-pressure cylinder.
Resultant effect includes caused by the utility model：
The utility model simple structure is reasonable, easy to use, and sealing gasket is improved by increasing skeleton filling in rubber
Intensity, so as to improve the anti-pressure ability of sealing, can both meet seal request, improve the service life of sealing gasket again.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment sealing gasket.
Word shows that arrow shows the oil-air pressure stress of sealing gasket relative to inside and outside cylinder seal in figure
Direction.Wherein, identical part identical reference in the accompanying drawings；Accompanying drawing is not drawn according to the ratio of reality.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Embodiment
A kind of novel high-strength sealing gasket, as shown in figure 1, section is T-shaped, including pad 1 and flange 2, the flange 2 with
The pad 1 is vertically affixed；Being horizontally disposed with the pad 1 has metal transversum 3, and being vertically arranged with metal in the flange 2 erects
Bone 4, the metal transversum 3 and the perpendicular bone 4 of the metal are vertical affixed.
The metal transversum 3 can not only avoid the excess compression of pad 1 when cylinder assembles, and ensure sealing reaction force,
And when can be rushed outside the high-temperature oil gas burning of cylinder, bone 4 is erected by metal and improves the lateral rigidity of flange 2, weakens sealing gasket
Deformation.
In the flange 2, the metal erects the side of bone 4 and is fixedly connected with leaf spring 5.The leaf spring 5 is arranged with parallel more
Group, and be bent downwardly.
In a ring, the leaf spring 5 is arranged in the flange 2 in the outside of sealing gasket 1 sealing gasket.It is new according to this, it is described
Leaf spring 5 can ensure sealing gasket toughness, the and can increase rigidity of flange 2, improve compression reaction in 2 side loaded of flange
Power, it is ensured that outer side seal is bonded.
The top surface of pad 1 is alternate to be provided with oil groove 11 and rib 12, and the gradient of rib 12 on the outside of the sealing gasket is less than
The gradient of rib 12 on the inside of the sealing gasket.The oblique rib 12 can further increase the lateral rigidity of sealing gasket, really
Sealing intensity of the secrecy packing in high-pressure cylinder.
The utility model is described above with reference to preferred embodiment, but the scope of protection of the utility model is not
Limited to this, any all technical schemes fallen within the scope of the appended claims are in the scope of protection of the utility model.
In the case of not departing from the scope of the utility model, various improvement can be carried out to it and can be replaced with equivalent therein
Part.Especially, as long as structural hazard is not present, the every technical characteristic being previously mentioned in each embodiment can be in any way
Combine.
