Description
Technical field
The invention belongs to automotive accessory technical fields, are related to a kind of automobile booster accessory, and in particular to a kind of
Automobile booster sebific duct.
Background technique
Currently, more and more automobiles can all use turbocharger as standard configuration.It needs to use in turbocharger
Sebific duct.But the hot properties of turbocharger is unable to satisfy most rubber all.
Currently, fluorubber is the mainstay material of turbocharger sebific duct.It is, as shown in Figure 1, entire turbocharger
Sebific duct is all made of fluorubber, and the wall thickness of entire sebific duct is 2.5-3.0mm.But fluorubber is expensive, so that turbine increases
The relative cost of depressor sebific duct is higher, how to reduce booster sebific duct into the original overall cost for reducing turbocharger, increases
The effective competition power in this huge market of turbocharger sebific duct becomes a urgent problem.
Meanwhile it is not only at high cost using the sebific duct of fluorubber, and due to the poor processability of fluorubber, so that product is qualified
Rate is lower, further increases cost.Moreover, purely the structure made of fluorubber keeps product pressure resistance relatively poor, easily expand
Deng relatively low using the lower service life for a long time.Moreover, sebific duct made of fluorubber has permeability, it is difficult to meet the requirement of state VI
Low emission environmental requirement.Meanwhile weight is bigger, it is difficult to meet the light-weighted requirement of automobile industry.
Therefore, in view of the above-mentioned technological deficiency of the prior art, there is an urgent need to develop a kind of novel automobile booster sebific duct.
Summary of the invention
It is an object of the invention to overcome disadvantage existing in the prior art, a kind of automobile booster sebific duct is provided, is dropped
Low production cost, improves resistance to pressure, the expansibility resistance, low-permeability of product, and have good heat-resisting quantity.
To achieve the goals above, the invention provides the following technical scheme:
A kind of automobile booster sebific duct comprising internal layer, which is characterized in that the internal layer is made of fluorubber, described
The outside of internal layer is equipped with middle layer, is equipped with outer layer in the outside in the middle layer, the middle layer and outer layer are all by ethylene-acrylate rubber
Glue is made, also, aramid line is provided between the middle layer and outer layer, and the aramid line forms enhancement layer.
Further, wherein the internal layer with a thickness of 0.6-0.8mm.
Further, wherein the middle layer with a thickness of 0.7-0.9mm.
Still further, wherein, the outer layer with a thickness of 1.0-1.2mm.
Compared with the existing sebific duct made of fluorubber, automobile booster sebific duct of the invention has following Advantageous
Effect
1, automobile booster sebific duct of the invention uses FKM (fluorubber)/AEM (ethylene-acrylate rubber)/AR (virtue
Synthetic fibre line)/AEM (ethylene-acrylate rubber) structure, the usage amount of fluorubber is reduced, automobile booster sebific duct is reduced
Cost.
2, automobile booster sebific duct of the invention forms enhancement layer using aramid line, increases the strong of automobile booster sebific duct
Degree, the service life is longer.
3, automobile booster sebific duct of the invention reduces infiltration capacity, reduces discharge, and meets VI New Set of state to row
The strict demand put, it is more environmentally-friendly.
4, automobile booster sebific duct weight relative reduction of the invention, meets the light-weighted requirement of automobile industry.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the automobile booster sebific duct of the prior art.
Fig. 2 is the structural schematic diagram of automobile booster sebific duct of the invention.
Specific embodiment
A specific embodiment of the invention is described with reference to the accompanying drawing, still, the content of the drawings and specific embodiments is not
As limitation of the present invention.
Fig. 2 shows the structural schematic diagrams of automobile booster sebific duct of the invention.As shown in Fig. 2, increasing with existing automobile
Difference is made using pure fluorubber in depressor sebific duct, and automobile booster sebific duct of the invention is multilayered structure.
Specifically, automobile booster sebific duct of the invention includes internal layer 1.The internal layer 1 is made of fluorubber (FKM).With
Fluororubber layer is different with a thickness of 2.5-3.0mm in existing automobile booster sebific duct, in the present invention, the thickness of the internal layer 1
Only 0.6-0.8mm.In this way, greatly reducing the usage amount of fluorubber, the overall cost of automobile booster sebific duct can be made to reduce
10%~15%.
Middle layer 2 is equipped in the outside of the internal layer 1.Outer layer 3 is equipped in the outside in the middle layer 2.Wherein, the middle layer 2
It is all made of ethylene-acrylate rubber (AEM) with outer layer 3.
In the present invention, the middle layer 2 with a thickness of 0.7-0.9mm.The outer layer 3 with a thickness of 1.0-1.2mm.This
Sample, so that the integral thickness of automobile booster sebific duct is 2.3-2.9mm, with automobile booster glue made of existing pure fluorubber
The wall thickness of pipe is similar.Simultaneously as the relative density of ethylene-acrylate rubber is less than the density of fluorubber, and therefore, the present invention
Automobile booster sebific duct weight relative reduction, meet the light-weighted requirement of automobile industry.
Meanwhile in the present invention, aramid line 4 is provided between the middle layer 2 and outer layer 3.Due to the intensity of aramid line
Height, and there is characteristic resistant to high temperature, aramid line 4 is set between 2 and outer layer 3 in middle level, automobile booster glue can be greatly increased
The voltage endurance capability and intensity of pipe, it is, the aramid line 4 forms enhancement layer.By the way that the aramid line 4 is arranged, vapour can be made
The burst pressure of vehicle booster sebific duct reaches 6MPa or more and expansion rate substantially increases within 5% under the pressure of 1MPa
The performance of automobile booster sebific duct.
It should be noted that aramid line 4 is only arranged between 2 and outer layer 3 in middle level, the setting of aramid line 4 can't make
Automobile booster sebific duct wall thickness increase how much, therefore, the integral thickness of automobile booster sebific duct of the invention is still 2.3-
2.9mm or so is suitable with the thickness of automobile booster sebific duct made of existing pure fluorubber.
In the present invention, it is preferred to which the aramid line 4 is Du Pont kavlar aramid line (AR).Du Pont's kavlar aramid line
With preferably intensity and heat-resisting quantity, the effect of enhancing can be better played.
Compared with the single layer structure of existing automobile booster sebific duct, automobile booster sebific duct of the invention is multilayered structure,
Multilayered structure reduces infiltration capacity, reduces discharge, meets strict demand of VI New Set of state to discharge, more environmentally-friendly.
Automobile booster sebific duct of the invention by upper steam turbine booster OTS (off tooling samples, i.e.,
Tooling exemplar) verifying, and continuous small quantities of 800 sets of order.It is expected that the upper vapour product annual consumption is 10000 sets, annual value of production 200W, often
Save 20W~30W member year.The above embodiment of the present invention is only
It is the restriction to embodiments of the present invention.For those of ordinary skill in the art, on the basis of the above description
It can also make other variations or changes in different ways.Here all embodiments can not be exhaustive.It is all to belong to
The obvious changes or variations that technical solution of the present invention is extended out are still in the scope of protection of the present invention.
