Abstract
The scalable silencing apparatus of automobile, belongs to automobile technical field.All linked together by the means of welding with the end cap at suppressor case two ends to solve the core pipe of existing silencing apparatus inside, such high temperature gas flow can make silencing apparatus core tube swelling by the heat that silencing apparatus produces, because described core pipe welds with the end cap at suppressor case two ends, expansion coefficient may be different, thus silencing apparatus may be caused to produce the problem of fracture.The left end of described core pipe outer side wall welds with the left end of case inside wall, and the scalable silencing apparatus of described automobile also comprises Steel Wool filler ring; The left end of core pipe stretches out housing 1.5mm, Steel Wool filler ring is provided with between the right-hand member of core pipe outer side wall and the right-hand member of case inside wall, core pipe welds with Steel Wool filler ring, core pipe is suspended in housing, core pipe right side distance housing right side 20mm, is full of muffler material in the ring cavity between core pipe and housing.The utility model is used for the exhausting and denoising of motor car engine.
Description
Technical field
The utility model relates to a kind of silencing apparatus of automobile, is specifically related to a kind of scalable silencing apparatus of automobile, belongs to automobile technical field.
Background technique
Silencing apparatus plays an important role the exhaust sound reducing motor car engine, forms primarily of housing, core pipe and muffler material.It is as a part for exhaust duct, should ensure that exhaust is unimpeded, the little and some strength of resistance.Arrange inside silencing apparatus many sound insulation dish and pipelines being full of aperture, when waste gas enters silencing apparatus from outlet pipe, and after the aperture on sound insulation dish and pipeline is discharged, the sound that waste gas produces is just very little, thus plays the effect of noise elimination.
The core pipe of usual silencing apparatus inside is all linked together by the means of welding with the end cap at suppressor case two ends, such high temperature gas flow can make silencing apparatus core tube swelling by the heat that silencing apparatus produces, because described core pipe welds with the end cap at suppressor case two ends, expansion coefficient may be different, thus silencing apparatus may be caused to produce fracture.
Summary of the invention
The purpose of this utility model is to overcome the deficiency existed in above-mentioned technology, provides a kind of scalable silencing apparatus of automobile
,it adopts floated structure, and simple and compact for structure, reasonable in design, be easy to manufacturing, cost is low, effectively can overcome the harm that temperature is brought to silencing apparatus.
For achieving the above object, the utility model provides following technological scheme:
The scalable silencing apparatus of automobile, it comprises housing, core pipe and muffler material, and the left end of described core pipe outer side wall welds with the left end of case inside wall, and the scalable silencing apparatus of described automobile also comprises Steel Wool filler ring; The left end of core pipe stretches out housing 1.5mm, Steel Wool filler ring is provided with between the right-hand member of core pipe outer side wall and the right-hand member of case inside wall, core pipe welds with Steel Wool filler ring, core pipe is suspended in housing, core pipe right side distance housing right side 20mm, is full of muffler material in the ring cavity between core pipe and housing.
The beneficial effect of above technological scheme is adopted to be:
1, the left end of core pipe outer side wall welds with the left end of case inside wall, and be provided with Steel Wool filler ring between the right-hand member of core pipe outer side wall and the right-hand member of case inside wall, core pipe welds with Steel Wool filler ring, and core pipe is suspended in housing.Like this, when high temperature gas flow is by core pipe, when core pipe expands because high temperature produces and stretches, because core pipe one end suspends, thus avoid the cracking phenomena of welding bead, extend the working life of silencing apparatus.
2, the left end of core pipe stretches out housing 1.5mm, core pipe right-hand member stretches out Steel Wool filler ring 2mm, core pipe is suspended in housing, core pipe right side distance housing right side 20mm, to ensure the flying height of core pipe in housing, when high temperature gas flow is by core pipe, because core pipe left end is fixed, right-hand member can spreading, thus reduces phenomenon of rupture and occur.
3, simple and compact for structure, reasonable in design, the reliable operation of the utility model, be easy to manufacturing, cost is low.
Accompanying drawing explanation
Fig. 1 is the main cross-sectional schematic of the scalable silencing apparatus of the utility model automobile.
In figure: 1-housing; 2-core pipe; 3-muffler material; 4-Steel Wool filler ring.
Embodiment
The preferred implementation of the scalable silencing apparatus of the utility model automobile is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the scalable silencing apparatus of automobile, it comprises housing 1, core pipe 2 and muffler material 3, and the left end of described core pipe 2 outer side wall welds with the left end of housing 1 madial wall, and the scalable silencing apparatus of described automobile also comprises Steel Wool filler ring 4; The left end of core pipe 2 stretches out housing 1 outside, and core pipe 2 extrusion is 1.5mm, Steel Wool filler ring 4 is provided with between the right-hand member of core pipe 2 outer side wall and the right-hand member of housing 1 madial wall, core pipe 2 welds with Steel Wool filler ring 4, core pipe 2 is suspended in housing 1, core pipe 2 right side distance housing 1 right side 20mm, is full of muffler material 3 in the ring cavity between core pipe 2 and housing 1.
Described core pipe 2 right-hand member stretches out Steel Wool filler ring 4, and extrusion is 2mm.
