Abstract
The utility model discloses the compound end cone of a kind of exhaustion system for automobile, comprise internal layer end cone, outer end cone, by combining after pressing between internal layer end cone and outer end cone, internal layer end cone and outer end cone do not contact with each other in subregion.Adopt end of the present utility model to bore, only have the end of linkage function cone to achieve function that is heat insulation, noise reduction in the past; Achieve the requirement more rationally worked of product; The more important thing is the part adopting several functions unification, reduce the consumption of auxiliary material and the energy, realize energy-saving and emission-reduction, the development of propelling vehicle draining technology, reduce environmental pollution, the requirement of response global environmental protection; And it is rational in infrastructure, simple for production.
Description
Technical field
The utility model relates to auto parts and components field, just relates to the compound end cone of a kind of automobile exhaust gas system specifically.
Background technology
End cone is the vitals that automobile exhaust system carrier connects, and is also the most important function of such part.Slip by development propelling in technology, need a part in conjunction with multiple function, vital effect can be had to reduction energy consumption and reduction weight.End cone is one of important parts of automobile exhaust system, plays interconnective effect in the entire system.The noise reduction of motor field current gas extraction system, heat insulation all by adopting acoustic material and heat-barrier material to realize.Realize end cone under the prerequisite of connection function, carry out heat insulation, Research of Noise Reduction, realize several functions, reduce energy consumption, the paces promoting energy-saving and emission-reduction.Existing end cone function singleness on the market, mostly adopt welding procedure to make, weld seam is many and appearance and size is difficult to control.
Summary of the invention
Goal of the invention: the utility model object is to overcome above-mentioned defect, provides and can realize end cone part under the prerequisite realizing self function, can reduce the function of noise, isolated heat simultaneously.The function of improving product, reduces the consumption of auxiliary material, alleviates the weight of gas extraction system.Actualizing technology difficult point, reduces energy consumption.
Technical scheme: in order to solve the problems of the technologies described above, the compound end cone of a kind of exhaustion system for automobile described in the utility model, comprise internal layer end cone, outer end cone, by combining after pressing between internal layer end cone and outer end cone, internal layer end cone and outer end cone do not contact with each other in subregion.
Further: one end internal layer end cone that internal layer end cone and outer end cone combine exceeds outer end cone, the other end internal layer end cone that internal layer end cone, outer end cone combine is bored lower than skin end.
Described in further: the space that internal layer end cone and outer end bore the region that do not contact with each other is 0-0.3mm.
Further: by combining after pressing between internal layer end cone and outer end cone, reach the withdraw force of more than 3000N.
Further: the wall ratio of internal layer end cone and outer end cone is 0.8:1.5.
Beneficial effect: adopt end of the present utility model to bore, was only having the end of linkage function cone to achieve function that is heat insulation, noise reduction in the past; Achieve the requirement more rationally worked of product; The more important thing is the part adopting several functions unification, reduce the consumption of auxiliary material and the energy, realize energy-saving and emission-reduction, the development of propelling vehicle draining technology, reduce environmental pollution, the requirement of response global environmental protection; And it is rational in infrastructure, simple for production.
Accompanying drawing explanation
