According to the connecting structure of the exhaust manifold and the support, the position of an outlet end of the exhaust manifold is fixedly connected with a connecting seat, and the support is fixed on the connecting seat through a detachable structure. The connecting structure of the exhaust manifold and the support does not influence the heat insulation effect of the heat shield, enables the service lives of the exhaust manifold and the support to be long, can guarantee normal running of the three-way catalytic converter, and is convenient to install and low in cost.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to the linkage structure of a kind of gas exhaust manifold and support.
Background technique
Along with the development of society, the reinforcement of people's environmental consciousness, country is also more and more stricter to the requirement of motor vehicle emission, for reaching emission standard, practices thrift cost, and present increasing automobile adopts the corrosion resistant plate gas exhaust manifold.Because stainless exhaust manifold is compared with the cast iron gas exhaust manifold; Wall thinner and also through punching press, be welded; And the position of gas exhaust manifold is in the hot junction, and so stressed complicacy is in order to guarantee the intensity of gas exhaust manifold; Prevent that gas exhaust manifold from use rupturing, often need support and locate through an auxiliary stand.
Its support 4 of the linkage structure of existing gas exhaust manifold and support normally directly is welded on (as shown in Figure 2) on the gas exhaust manifold 1.The high temperature that the linkage structure of existing gas exhaust manifold 1 and support 4 is produced in welding process can make gas exhaust manifold support 4 produce certain deformation; Thereby the position of mounting hole that causes support 4 exceeds design tolerance can't assemble it with the cylinder body immovable point; Even fit on; The stress that exists also makes gas exhaust manifold 1 cracking or gas leakage, the working life of having reduced gas exhaust manifold 1 and support 4 than conference.Simultaneously, damaging the housing of catalyst converter and high temperature that welding produces when the position of the ternary catalyzing unit of the position of welding in the gas exhaust manifold is nearer easily can affect to the precious metal in the catalyzer, thereby influences the normal operation of catalyst converter.In addition, support 4 is welded on the gas exhaust manifold 1, need not only influence the effect of heat insulation of thermal shield 7 opening a hole on the thermal shield 7 so that it can be installed on the gas exhaust manifold 1 when thermal shield 7 is installed, and the installation of thermal shield 7 and manufacture also comparatively numerous and diverse.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of easy for installationly, and the long service life of gas exhaust manifold and support can not influence the linkage structure of the gas exhaust manifold and the support of thermal shield effect of heat insulation.
The purpose of the utility model can realize through following technical proposal: the linkage structure of a kind of gas exhaust manifold and support; It is characterized in that; The outlet end place of described gas exhaust manifold is fixed with connecting base, and described support is fixed on the connecting base through demountable structure.The support of this gas exhaust manifold is to be fixed on the connecting base that is connected mutually with the gas exhaust manifold outlet end through demountable structure, and the high temperature of having avoided welding to produce makes deformation of timbering reach the influence to gas exhaust manifold, has prolonged the working life of gas exhaust manifold and support.Also guaranteed simultaneously the integrity and the effect of heat insulation thereof of exhaust manifold thermal shield, saved the operation that the hole is gone in thermal shield processing, installed also comparatively easy.
In the linkage structure of above-mentioned gas exhaust manifold and support, described connecting base is connected through welding and gas exhaust manifold.
In the linkage structure of above-mentioned gas exhaust manifold and support, have attachment hole on the described connecting base, the outlet end of described gas exhaust manifold is located in the connection hole.The position of connecting base and gas exhaust manifold welding is positioned at the outlet end of gas exhaust manifold; Ternary catalyzing unit in gas exhaust manifold is far away; Can not exert an influence, ensure the normal operation of ternary catalyzing unit, can the installation of thermal shield not exerted an influence simultaneously yet ternary catalyzing unit.
In the linkage structure of above-mentioned gas exhaust manifold and support, described demountable structure is the bolt and nut linkage structure.Support is fixed on the connecting base through bolt and nut; Support can rotate and with bolt certain matching gap arranged around bolt; Therefore, with cylinder body immovable point installation process in certain adjustment space arranged, the stress of having avoided rigidity to install being produced is to the influence of gas exhaust manifold; Make gas exhaust manifold fixing more firm, also prolonged the working life of outlet pipe simultaneously.
In the linkage structure of above-mentioned gas exhaust manifold and support, described connecting base is tabular.
Compared with prior art; This gas exhaust manifold is installed comparatively easy with the linkage structure of support; Support is fixed on through bolt and nut on the connecting base that is connected mutually with the outlet end of gas exhaust manifold, the immovable point of support and cylinder body has certain adjustment space in installation process, and the stress of having avoided rigidity to install being produced is to the influence of gas exhaust manifold; Make the fixing more firm of gas exhaust manifold, prolonged the working life of gas exhaust manifold and support.Need perforate on thermal shield when thermal shield is installed yet, simplified the production technology of thermal shield, guaranteed the effect of heat insulation of thermal shield, reduced required cost of production.The position of connecting base and gas exhaust manifold welding simultaneously is far away from the ternary catalyzing unit in the gas exhaust manifold, can not impact ternary catalyzing unit and catalyzer wherein, has ensured the normal operation of ternary catalyzing unit.
