Abstract
A kind of suppressor case comprising the inner plating of eyelet portion and the inside positioned at the eyelet portion, wherein being equipped with gap between the inner plating and the eyelet portion.Compared to the prior art, it when the utility model may insure that core assembly is installed in suppressor case by the way that gap is arranged, is interference fitted between core assembly and suppressor case；Meanwhile reduction makes eyelet portion not deform, it is ensured that the sealing effect in eyelet portion the stressing influence in eyelet portion.
Description
Technical field
The utility model relates to a kind of suppressor cases, 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 journeys
The wall thickness of the reduction material of degree, but while the reduction of material wall thickness, increase the difficulty of shell processing.
Traditional suppressor case generally uses eyelet technique, and specifically the flitch of suppressor case is rolled into after bilayer
Final joint portion carries out eyelet, is tightly bonded at eyelet with internal layer flitch.Suppressor case after processing is completed, by core assembly edge
It is axially inserted into suppressor case, in this process, should ensure that core assembly and suppressor case keep being interference fitted, guarantee
Core assembly is installed in place；It after ensuring installation again, will not deform at the eyelet of suppressor case, to ensure at eyelet
Sealing effect.
After wall thickness reduction, the core assembly of silencer is easy to cause at eyelet and occurs during installation because of interference fit
Deformation, finally makes to leak at eyelet.
Utility model content
The purpose of this utility model is to provide a kind of suppressor cases reduced to eyelet portion stressing influence.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of suppressor case comprising eyelet portion
And the inner plating of the inside positioned at the eyelet portion, wherein being equipped with gap between the inner plating and the eyelet portion.
As the further improved technical solution of the utility model, the inner plating with core assembly to match.
As the further improved technical solution of the utility model, the inner plating with core assembly to be interference fitted.
Compared to the prior art, the utility model may insure that core assembly is installed into suppressor case by the way that gap is arranged
When middle, it is interference fitted between core assembly and suppressor case；Meanwhile reduction is to the stressing influence in eyelet portion.So set, both
It can guarantee that core assembly is installed in place, and after can ensure that installation, the eyelet portion of suppressor case will not deform, it is ensured that eyelet
The sealing effect in portion.
Detailed description of the invention
Fig. 1 is the diagrammatic cross-section of the utility model suppressor case.
Fig. 2 is the partial enlarged view of circled portion in Fig. 1.
Specific embodiment
It please join shown in Fig. 1 and Fig. 2, the utility model discloses a kind of suppressor case 1 comprising eyelet portion 11 and position
Inner plating 12 in the inside in the eyelet portion 11, wherein being equipped with gap 13 between the inner plating 12 and the eyelet portion 11.
The inner plating 12 with core assembly (not shown) to match.Preferably, the inner plating 12 to core
Parts interference fit.
When suppressor case 1 after processing is completed, core assembly is axially inserted into suppressor case 1.In this process,
Because there is certain gap 13 between eyelet portion 11 and inner plating 12, it can be ensured that when core assembly is installed in suppressor case 1,
It core assembly and is interference fitted between inner plating 12.Meanwhile reduction is to the stressing influence in eyelet portion 11.So set, can
Guarantee that core assembly is installed in place, and after can ensure that installation, the eyelet portion 11 of suppressor case 1 will not deform, it is ensured that lock
The sealing effect in seam portion 11.
Above embodiments are merely to illustrate the utility model and not limit technical solution described in the utility model, right
The understanding of this specification should be based on person of ordinary skill in the field, although this specification is referring to the above embodiments
Detailed description is had been carried out to the utility model, still, those skilled in the art should understand that, technical field
Technical staff still the utility model can be modified or replaced equivalently, and all do not depart from the essence of the utility model
The technical solution and its improvement of mind and range, should all cover in the scope of the claims of the utility model.
Claims (3)
1. a kind of suppressor case, which is characterized in that the inner plating of the inside including eyelet portion and positioned at the eyelet portion,
Described between inner plating and the eyelet portion be equipped with gap.
2. suppressor case as described in claim 1, it is characterised in that: the inner plating with core assembly to match.
3. suppressor case as claimed in claim 2, it is characterised in that: the inner plating with core assembly interference to match
It closes.
