Description
Technical field
The utility model is related to automotive field, more particularly to a kind of enmgine exhaust flange arrangement.
Background technology
Enmgine exhaust flange of the prior art generally uses monoblock type or split type two kinds of arrangement forms, such as schemes
Shown in 1, monoblock type enmgine exhaust flange a includes gas port sealing surface a1, bolt load face a2, flange face a3, and this three
In person is all generally aligned in the same plane, monoblock type enmgine exhaust flange a is bolted, this structure due to Flange Plane compared with
Greatly, punching plane degree it is difficult to ensure that, under the influence of engine exhaust high temperature, temperature distortion amount is big, and deformation can not be compensated, and be drawn
Pressure between the row of rising monoblock type enmgine exhaust flange a and cylinder cap flange is uneven, and causes seal failure；While bolt
After tightening, monoblock type enmgine exhaust flange is without part (the bolt load face on bolt hole periphery) elastic deformation, bolt
Easily loosen, cause seal failure.As shown in Fig. 2 splitting cnginc air discharging manifold flange b be kept completely separate by 4 it is independent
Flange b1 is combined, and is fixed again by bolt, and the structure is in use there is also some defects, for example, whole row
Gas manifold mode is relatively low, vibrates larger, exhaust manifold failure easy to crack；And each independent flange face is smaller, become during welding
Shape, each flange face coplanarity is poor, and after bolt is tightened, air discharging manifold flange stress is larger, and engine is by alternate load
And during thermal shock, bolt easy fracture causes seal failure.
The content of the invention
In order to solve above-mentioned exhaust manifold in the prior art easily between failure and enmgine exhaust flange and cylinder cap flange
The technical problem of seal failure, the utility model provides a kind of enmgine exhaust flange arrangement, and concrete scheme is as follows：
A kind of enmgine exhaust flange arrangement, the enmgine exhaust flange arrangement uses integral design, respectively
Gas port sealing surface is separate, and each bolt load face is separate, gas port sealing surface, bolt load face and flange face three
In 3 layers of stepped arrangement,
The enmgine exhaust flange arrangement is one time punching molded.
Further, the gas port sealing surface is 4, and the bolt load face is 5.
Further, the bolt load face is higher than flange face, and gas port sealing surface is higher than bolt load face.
Further, bolt load face 0.4mm higher than flange face.
Further, gas port sealing surface 0.1mm higher than bolt load face.
Further, the enmgine exhaust flange arrangement, which is adopted, is bolted connection, in flange face orthographic projection plane
Interior, the line between the adjacent bolt hole center of circle passes through the exhaust outlet center of circle.
Further, the enmgine exhaust flange arrangement is one time punching molded using stainless steel materials.
Compared with prior art, a kind of enmgine exhaust flange arrangement that the utility model is provided, its each gas port
Sealing surface is mutually independent, therefore, and preferably, the manufacturability of product meets engine zero to the flatness of each gas port sealing surface
The design requirement of part.Furthermore, make flange local after each bolt fastening, that is, become at independent bolt load face
Shape, now flange is equivalent to elastomeric pad, even if without using elastomeric pad, bolt will not also loosen, preferable gas port plane
Degree and deformable separate bolt plane of load ensure that sealed reliability.The flange arrangement uses integral design, once
Punch forming, reduces the deflection of welding, improves the mode and rigidity of exhaust manifold, so improve the reliable of exhaust manifold
Property.And this global design, one-shot forming makes flange face for one piece of leveling face, and its coplanarity is good, corresponding engine exhaust discrimination
Pipe flange stress is smaller, and bolt is difficult failure, improves sealed reliability；In addition, in flange face orthographic projection plane, it is adjacent
Line between the bolt hole center of circle makes the distribution of bolt presses power more uniform, further increases sealing by the exhaust outlet center of circle
Reliability.
Brief description of the drawings
The utility model will be hereinafter described in more detail based on embodiment and refer to the attached drawing, wherein：
Fig. 1 is prior art monoblock type enmgine exhaust flange overall structure diagram；
Fig. 2 is prior art splitting cnginc air discharging manifold flange overall structure diagram；
Fig. 3 is the utility model enmgine exhaust flange installation diagram；
Fig. 4 is the utility model flange face front view；
Fig. 5 is each working face difference of height schematic diagram of the utility model.
In the accompanying drawings, identical part uses identical reference, and accompanying drawing is not drawn according to actual ratio.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As in Figure 3-5, the present embodiment is provided a kind of enmgine exhaust flange arrangement 1 and the phase of exhaust manifold 2
Connect, be connected by bolt with cylinder cap flange (not shown).The enmgine exhaust flange arrangement 1 uses monoblock type
Design, each gas port sealing surface 13 is separate, and each bolt load face mutual 12 is independent, gas port sealing surface 13, bolt load
Face 12 and the three of flange face 11 are in 3 layers of stepped arrangement, and the enmgine exhaust flange arrangement 1 is one time punching molded.
In said structure, each gas port sealing surface 13 is mutually independent, therefore, processes the gas port sealing surface 13 formed
Flatness preferably, the manufacturability of product meets the design requirement of engine component；Furthermore, make flange after each bolt fastening
It is local, that is, deformed at independent bolt load face 12, now flange is equivalent to elastomeric pad, even if without using bullet
Property pad, bolt will not also loosen；The preferable flatness of gas port sealing surface 13 and deformable separate bolt plane of load 12 are equal
It ensure that sealed reliability.It is one time punching molded using integral design, the deflection of welding is reduced, exhaust is improved
The mode and rigidity of manifold 2, reduce vibration, so improve the reliability of exhaust manifold 2.And this global design, once
Shaping makes flange face 11 be one piece of leveling face, and its coplanarity is good, and the corresponding stress of enmgine exhaust flange arrangement 1 is smaller,
Bolt is difficult failure, further increases sealed reliability.
