Description
Technical field
The present invention relates to a kind of partitions of silencer, belong to engine exhaust system technical field.
Background technique
In recent years, target for energy-saving and emission-reduction has all been formulated in the multiple countries and regions in the world, and it is riding that China also clearly arrives the year two thousand twenty
Vehicle new car average fuel consumption reaches 5L/100km, and the pressure of energy-saving and emission-reduction is larger.In current many energy-saving and emission-reduction modes,
Automotive light weight technology is to be easiest to realization, the relatively large mode of potentiality.For riding gasoline car, every reduction 100kg can at most be saved
Oily 0.39L/100km.
So-called automotive light weight technology refers to and is guaranteeing that every important indicator such as automotive safety all meets country and professional standard is wanted
In the case where asking, in order to increase the utilization efficiency of the energy, make that its is more energy saving, safety, by using various advanced technologies or
Special material mitigates the process of car mass as much as possible.In the above context, automobile vendor is to the light-weighted requirement of components
It increases year by year.
The components of automobile exhaust system mostly use stainless steel material, realize that the most effective means of its lightweight are maximum limits
The wall thickness of the reduction material of degree.But while material wall thickness reduces, increase the difficulty of welding.In the relatively thin situation of base material wall thickness
Under, if welding current is big when welding, it is easy to base material burn-through；If welding current is small, base material fusion penetration is small, and welding is strong
It spends low, influences product quality.So gap is smaller for the welded connecting of thin-wall part, be more conducive to improve welding quality.
In traditional exhaust system structure, a complete flange is usually directly stamped out on the partition of silencer,
The flange of the partition of core pipe and silencer is by being welded and fixed.If the wall thickness of partition is thicker (1.0 ± 0.2mm), contact gap
It is of less demanding to welding control because base material wall thickness is thicker although contact gap is larger in ± 1.0mm or so.
But (0.6 ± 0.2mm) then requires the outer wall of core pipe to ensure welding quality in the exhaust system that material is thinned
Gap between the inner wall of the flange of partition is the smaller the better, usually controls the machining accuracy of flanging bore, but thus bring
Problem is that difficulty of processing increases, and scrappage is higher, and processing cost is high.
Summary of the invention
The purpose of the present invention is to provide a kind of partitions of silencer that can be realized and be reliably connected with core pipe.
To achieve the above object, the present invention adopts the following technical scheme: a kind of partition of silencer comprising main part,
The main part includes the through-hole to core tube feeding insertion, and the main part further includes the more valves for being centered around the periphery of the through-hole
Formula flange, the flange direction of the multi-clove type flange and the plane at the place of the main part are at an acute angle, in order in the core
When pipe is inserted into the through-hole, increase the flexible contact of the multi-clove type flange and the core pipe.
Technical solution as a further improvement of that present invention, the main part be equipped with gas supply stream across several perforation.
Technical solution as a further improvement of that present invention, the partition include the curved of the outer rim bending from the main part
Flanging, the bending edge is the partition to be fixed in the silencer.
Technical solution as a further improvement of that present invention, the multi-clove type flange and the core pipe are interference fitted.
Technical solution as a further improvement of that present invention, the partition include being located at the two neighboring multi-clove type flange
Between notch.
Compared to the prior art, the present invention passes through setting multi-clove type flange and flange direction and the place of the main part
Plane is at an acute angle, in order to increase the flexibility of the multi-clove type flange and the core pipe when the core pipe is inserted into the through-hole
Contact improves being reliably connected for partition and core pipe.

Specific embodiment
It please join shown in Fig. 1 to Fig. 6, present invention discloses a kind of partitions 1 of silencer comprising main part 2 and from institute
State the bending edge 3 of the outer rim bending of main part 2.The bending edge 3 is the partition 1 to be fixed in the silencer.
The main part 2 include to core tube feeding 4 be inserted into through-hole 21 and be centered around the through-hole 21 periphery it is more
Flap-type flange 22.The flange direction of the multi-clove type flange 22 and the plane at the place of the main part 2 are at an acute angle, in order to
When the core pipe 4 is inserted into the through-hole 21, increase the flexible contact of the multi-clove type flange 22 and the core pipe 4.
The partition 1 includes the notch 23 between the two neighboring multi-clove type flange 22, so that the multi-clove type
Flange 22 has certain elasticity.Preferably, the multi-clove type flange 22 is interference fitted with the core pipe 4.
In addition, the main part 2 be additionally provided with gas supply stream across several perforation 24.
Compared to the prior art, the present invention can be realized the joint gap for reducing the core pipe 4 and the partition 1, in this way
Not only the processing cost of base material can have been reduced, but also welding quality can be promoted, the final effective popularization realizing exhaust system and being thinning.
Above embodiments are merely to illustrate the present invention and not limit the technical scheme described by the invention, to this specification
Understanding should based on person of ordinary skill in the field, although this specification referring to the above embodiments to the present invention
Detailed description is had been carried out, still, those skilled in the art should understand that, person of ordinary skill in the field is still
Can so modify or equivalently replace the present invention, and all do not depart from the spirit and scope of the present invention technical solution and
It is improved, and should all be covered in scope of the presently claimed invention.
