Abstract
A kind of silencer comprising shell, positioned at the first end cover of one end of the shell and the second end cover of the other end positioned at the shell.The silencer further includes the hollow out supporting baffle in the shell, flange made of the hollow out supporting baffle includes main part and bends from the edge of the main part.The main part includes the hollow-out parts positioned at middle part.So set, hollow out supporting baffle of the invention can reinforce the intensity of shell；By the way that hollow-out parts are arranged, weight is alleviated, conducive to the final effective popularization realizing exhaust system and being thinning.
Description
Technical field
The present invention relates to a kind of hollow out supporting baffle and silencers, 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, it will affect whole structural strength.
In traditional automobile exhaust system, after the shell of silencer is thinned, for the overall stiffness for ensuring shell, general meeting
It is realized by increasing the quantity of internal supporting baffle.However, the increasing of total quality will certainly be brought by increasing internal supporting baffle
Add, this is contradicted with light-weighted requirement.
The rigidity of suppressor case is lower, and when air pulse is by silencer chamber body, shell is more easy to happen high frequency vibrating
It is dynamic, the final acoustical behavior for influencing silencer.
Summary of the invention
The purpose of the present invention is to provide a kind of hollow out supporting baffle for capableing of reinforcement structure intensity and lighter in weight and disappear
Sound device.
To achieve the above object, the present invention adopts the following technical scheme: a kind of hollow out supporting baffle comprising main part with
And from flange made of the bending of the edge of the main part, the main part includes the hollow-out parts positioned at middle part.
Technical solution as a further improvement of that present invention, the outer edge of the hollow-out parts is close to the flange.
The invention further relates to a kind of silencers comprising shell, the first end cover positioned at one end of the shell and position
In the second end cover of the other end of the shell, the silencer further includes the aforementioned hollow out support block in the shell
Plate.
Technical solution as a further improvement of that present invention, the flanging welded is on the inner wall of the shell.
Compared to the prior art, hollow out supporting baffle of the invention can reinforce the intensity of shell；By the way that hollow-out parts are arranged,
Weight is alleviated, conducive to the final effective popularization realizing exhaust system and being thinning.
Detailed description of the invention
Fig. 1 is the perspective view of silencer of the present invention.
Fig. 2 is the stereoscopic schematic diagram of hollow out supporting baffle in Fig. 1.
Fig. 3 is the stereoscopic schematic diagram of another angle of Fig. 2.
Fig. 4 is the diagrammatic cross-section of the line A-A along Fig. 1.
Specific embodiment
It please join shown in Fig. 1 to Fig. 4, present invention discloses a kind of silencers 1 comprising shell 11 is located at the shell 11
One end first end cover 12 and the other end positioned at the shell 11 second end cover 13.
In order to improve the structural strength of the shell 11, the silencer 1 further includes the hollow out in the shell 11
Supporting baffle 14.The hollow out supporting baffle 14 is turned over including main part 141, from made of the bending of the edge of the main part 141
Side 142.The flange 142 is welded on the inner wall of the shell 11.
The main part 141 includes the hollow-out parts 143 positioned at middle part.So set, the hollow out supporting baffle 14 is in ring
Shape, outer ring are still a complete structure, so as to provide certain support for the shell 11.In addition, described engrave
The outer edge in empty portion 143 is close to the flange 142, largely to mitigate weight.Meanwhile the hollow out supporting baffle 14 is easy
Processing, and vary widely the internal structure of silencer 1.
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.
