Abstract
The invention relates to the field of automobile gas exhaust systems, and discloses a vehicle gas exhaust system with an elbow pipe structure. The system comprises a gas exhaust manifold assembly, a three-way catalyst converter assembly and a silencer assembly, wherein a gas outlet end joint of the gas exhaust manifold assembly is welded with a gas outlet end flange; a gas inlet end joint of the three-way catalyst converter assembly is welded with a gas inlet end flange; the gas outlet end flange is connected with the gas inlet end flange through a bolt; both the gas outlet end joint of the gas exhaust manifold assembly and the gas inlet end joint of the three-way catalyst converter assembly have elbow pipe structures; thus the flanges arranged between the gas exhaust manifold assembly and the three-way catalyst converter assembly can be conveniently connected through bolts; a gas inlet pipe of the catalyst converter has a short gas passage and a compact structure; the distance between the front end face of a catalyst converter carrier and a gas exhaust manifold outlet is shortened; and the discharge performance is improved.
Description
Technical field
The present invention relates to exhaustion system for automobile, particularly relate to a kind of gas exhaust manifold and ternary catalytic converter assembly linkage structure.
Background technique
Automobile factory considers for maintenance cost and arrangement space, generally with gas exhaust manifold, ternary catalyzing unit designs as an assembly separately, so just gas exhaust manifold need be exported A is connected with ternary catalyzing unit import B, if structure shown in employing Fig. 2 connects, then when the bolt D mounting point of adpting flange C and catalyst converter end pitch cone radius when nearer, pneumatic wrench tends to interfere with ternary catalyzing unit end awl E, thereby the problem that must just can avoid pneumatic wrench and ternary catalyzing unit to interfere away from adpting flange the ternary catalyzing unit position will certainly influence the catalytic effect of catalyst converter like this and then influence the car load discharging.Structure is often sacrificed discharging (carrier is far away from the gas exhaust manifold exit position) when having solved the assembly technology problem now, perhaps but can not guarantee assembly technology when satisfying emission request.For product designer, how to solve the problem that above-mentioned contradiction becomes everybody thinking.Design a kind of bend pipe structure in gas exhaust manifold and ternary catalyzing unit attachment portion and can make under the prerequisite that guarantees bolts assemblies technology that shortening the catalyst converter intake manifold length become possibility.
Summary of the invention
The object of the present invention is to provide the exhaustion system for automobile of the band bend pipe structure of a kind of simple in structure, compact, assembling, convenient welding, do not influence in assurance under the situation of car load discharging, solve above-mentioned exhaust manifold assembly and ternary catalytic converter assembly in the contradiction that satisfies between car load discharging and the assembly technology.
Technological scheme of the present invention is as follows,
A kind of exhaustion system for automobile with bend pipe structure, it comprises exhaust manifold assembly, ternary catalytic converter assembly and muffler assembly; Be welded with the outlet side flange on the outlet side joint of described exhaust manifold assembly, be welded with the inlet end flange on the inlet end joint of ternary catalytic converter assembly, the outlet side flange is connected by bolt with the inlet end flange; It is characterized in that: the outlet side joint of described exhaust manifold assembly and the inlet end joint of ternary catalytic converter assembly are bend pipe structure.
It is S-shaped that the outlet side joint of described exhaust manifold assembly and the inlet end joint of ternary catalytic converter assembly are connected the back by flange.
The present invention since in the employing of exhaust manifold assembly and ternary catalytic converter assembly connection part the bend pipe structure form, pneumatic wrench is subjected to the installing space restriction in the time of can avoiding construction bolt, interfere with ternary catalyzing unit awl end, simple in structure, easy to assembly, it is little that the catalyst converter admission line is taken up room, compact, shortened the distance of catalyst converter carrier front-end face and gas exhaust manifold outlet, make catalyst converter front end gas flow uniformity height, catalyst converter opens the combustion time to be shortened greatly, satisfied emission request, it is limited to be specially adapted to when the pneumatic wrench installing space, and discharging is had certain requirements on the microbus.

Fig. 3 is the assembling schematic representation of the present invention when catalyst converter and gas exhaust manifold are installed.
Embodiment:
Automobile exhaust system comprises exhaust manifold assembly 1, ternary catalytic converter assembly 2, muffler assembly 3 as shown in Figure 1, and the outlet side flange 5 of exhaust manifold assembly 1 and the inlet end flange of ternary catalytic converter assembly 28 are connected by bolt.
The present invention has carried out improving design to the tube shaped of exhaust manifold assembly 1 and ternary catalytic converter assembly 2 attachment portions, referring to Fig. 3, the outlet side joint 5 of exhaust manifold assembly is divided into the air inlet section and the section of giving vent to anger, the section of giving vent to anger and 7 welding of outlet side flange, air inlet section and 4 welding of gas exhaust manifold air flue, this outlet side joint 5 is crossed the crooked suitably angle of tube bender, forms bend pipe structure.The inlet end joint 10 of catalytic converter assembly 2 is divided into the also air inlet section and the section of giving vent to anger, air inlet section and 8 welding of inlet end flange, and the section of giving vent to anger and 11 welding of catalyst converter end awl, this inlet end joint 10 is also crossed the crooked suitably angle of tube bender, forms bend pipe structure.Two joints are connected with inlet end flange 8 by outlet side flange 7, whole formation S shape.When connecting outlet side flange 7 and inlet end flange 8 by stage clip 9 and stage clip bolt, pneumatic wrench 12 can become certain inclination angle to operate with horizontal plane, pneumatic wrench 12 just can be avoided catalyst converter end awl 11 like this, and can guarantee that catalyst converter carrier front-end face position can be too not far away from the gas exhaust manifold outlet, thereby solve the contradiction between assembling interference problem and the discharging.
