Description
Technical field
The utility model belongs to automobile engine technical field of sealing technology, and in particular to a kind of exhaust sealing of engine with supercharger
Structure.
Background technology
As shown in Figure 1, Figure 2, Figure 3 shows, the exhaust sealing structure of currently used engine with supercharger, including gasket 2, setting
Air discharging manifold flange 11 on exhaust manifold 1 and the booster flange 31 being arranged on booster 3 offer on gasket 2
Circular air flue hole 21, gasket 2 are formed by welding by the identical top substrate layer 23 of material thickness with underlying substrate 24, underlying substrate 24
Outer ledge be folded upward at and back bending formed bound edge, the bound edge wrap up top substrate layer 23 outer ledge, top substrate layer 23
Inside and the inside of underlying substrate 24 are bent in opposite direction, form the ring packing muscle 22 of cavity structure, air discharging manifold flange
11 end face is the flat surface coordinated with gasket 2, gasket 2 be assemblied in air discharging manifold flange 11 and booster flange 31 it
Between, it is fastened by three bolts.When work, gasket 2 is adjacent to exhaust manifold by the metal resilience performance of ring packing muscle 22
The end face of the end face and booster flange 31 of flange 11, the high-temperature gas being discharged from exhaust manifold 1 to sealing.
This exhaust sealing structure is suitable for the sealing of middle low heat loads, but for the higher engine of certain delivery temperatures
For, resilience performance declines ring packing muscle 22 at higher temperatures, and after experience works long hours, ring packing muscle 22 can quilt
Air discharging manifold flange 11,31 complete be collapsed of booster flange, remaining muscle height is almost nil, sealing function failure.
Invention content
The purpose of this utility model is to provide a kind of exhaust sealing structure of engine with supercharger, to improve the annular of gasket
The resilience performance of sealed muscle, avoids exhaust gas leakage.
The exhaust sealing structure of engine with supercharger described in the utility model, including gasket, setting are on exhaust manifold
Air discharging manifold flange and the booster flange that is arranged on booster, gasket be assemblied in enmgine exhaust flange and increase
Circular air flue hole is offered between depressor flange, on gasket, the edge in circular air flue hole is provided with ring packing muscle；The row
The end face of gas manifold flange offers the round heavy platform coordinated with ring packing muscle, the axial line of round heavy platform and the round gas
The axial line in road hole overlaps, and the diameter of round heavy platform is more than the outer diameter of the ring packing muscle, the depth of round heavy platform be more than or
The muscle for being less than the ring packing muscle equal to the depth of the monolayer material thickness of gasket, and round heavy platform is high.
Round heavy platform in the utility model is avoided that the muscle height of ring packing muscle by air discharging manifold flange, booster flange
Complete be collapsed improves the compression rebound of ring packing muscle to reduce the incipient plastic deformation after the assembly of ring packing muscle
Performance avoids exhaust gas leakage.

Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the utility model.
The exhaust sealing structure of engine with supercharger as shown in Figures 1 to 5, including gasket 2, setting are in exhaust manifold 1
On air discharging manifold flange 11 and the booster flange 31 that is arranged on booster 3, offer circular air flue hole on gasket 2
21, gasket 2 is formed by welding by the identical top substrate layer 23 of material thickness with underlying substrate 24, the outer ledge of underlying substrate 24
It is folded upward at and back bending forms bound edge, which wraps up the outer ledge of top substrate layer 23, the inside of top substrate layer 23 and lower layer
The inside of substrate 24 is bent in opposite direction, forms the ring packing muscle 22 of cavity structure（I.e. ring packing muscle 22 is located at circle
The edge in air flue hole）, the end face of air discharging manifold flange 11 offers the round heavy platform 12 coordinated with ring packing muscle 22, round heavy
The axial line of platform 12 is overlapped with the axial line in circular air flue hole 21, the diameter d of round heavy platform 121It is outer more than ring packing muscle 22
Diameter d2, the depth h of round heavy platform 121Equal to the monolayer material thickness of gasket 2（That is the thickness of top substrate layer 23）, and it is round heavy
The depth h of platform 121Less than the high h of muscle of ring packing muscle 222.Gasket 2 is assemblied in enmgine exhaust flange 11 and booster
Between flange 31, ring packing muscle 22 is corresponding with round heavy platform 12, enmgine exhaust flange 11, gasket 2, booster method
Orchid 31 is fastened by three bolts.When work, gasket 2 is adjacent to exhaust manifold by the metal resilience performance of ring packing muscle 22
The end face of the end face and booster flange 31 of the round heavy platform 12 of flange 11, the High Temperature Gas being discharged from exhaust manifold 1 to sealing
Body.
