Description
Technical field
The utility model relates to a kind of structure that improves turbosupercharged engine exhaust hot junction durability.
Background technique
The extensive attention of the strict day by day and economic fuel oil of the rules of environmental protection, turbosupercharged engine will be the trend of starting of following passenger car motor, therefore corresponding manifold catalyst converter has also been made corresponding change.As shown in Figure 1, common solution is that the inlet pipe connection 1 by a casting is connected with turbosupercharger, simultaneously be connected 3 with ternary catalyzing unit again, ternary catalyzing unit then is to be connected with the motor rigid body by a support 2, and play a supporting role, the outlet of catalyst converter couples together by flange and vent systems.This structure has solved turbosupercharger and has exported difficult point parallel and ground.But, also there is certain defective in this structure, because the quality of turbosupercharger and cast iron connecting tube is big, turbosupercharger and cast iron connecting tube are away from the motor rigid body simultaneously, lack the strong point, all structures all are to be connected with the motor rigid body by bolt on the manifold and support 2.This will cause manifold catalyst converter, turbosupercharger and motor to produce resonance.Thereby make whole system produce big amplitude, this will cause engine bolt loosening, and perhaps in engine support cracking and the structure ftracture in the zone of other weaknesses, influences the durability of whole system, the emission performance problem.
Summary of the invention
The purpose of this utility model provides a kind of structure that improves the turbosupercharged engine durability.
In order to achieve the above object; the technical solution of the utility model has provided a kind of structure that improves turbosupercharged engine exhaust hot junction durability; comprise catalyst converter; catalyst converter comprises shell and places the interior carrier of shell; between shell and carrier, be provided with liner; outside the inlet end of catalyst converter, be with inlet end protecting sheathing structure; it is characterized in that: the outlet side of catalyst converter connects stainless solleret box structural tube; stainless solleret box structural tube links to each other with turbosupercharger by connecting ring, is provided with the grooved supporting structure on catalyst converter.
Further, the inlet end of described shell bends inwards 30-60 °.
The jointing of described stainless solleret box structural tube and described catalyst converter is a footwear box structure, is formed with fluid air flue face on the inwall of described stainless solleret box structural tube.
On the outer side surface of described stainless solleret box structural tube, be provided with projection.
One side of described connecting ring links to each other with described turbosupercharger by a v-shaped structure, and opposite side is enclosed within by linkage structure outside the end of described stainless solleret box structural tube, and the surface of contact of this v-shaped structure and turbosupercharger is spherical sealing surface.
On described grooved supporting structure, be provided with positioning hole and waist shaped hole.
Described grooved supporting structure is connected with described shell seal.
The utility model has the advantages that: the design of connecting ring can be satisfied compact installation requirement, can regulate sealing means according to different application simultaneously.Stainless solleret boxlike connecting tube has the advantage with the same control inner flow passage of foundry goods, by the control runner, improve the fluid distribution attribute, but alleviated the quality of hot junction system simultaneously, and improved the intensity under the high temperature, avoid under the high temperature because the structural damage that causes of cast iron materials decreased performance.The structure of grooved support does not increase the quality of structure when improving intensity, by adopting the hole of racetrack, reduced manufacturing and assembling difficulty.And the liner of inlet end protection structure has then been protected liner, has reduced cost, has improved durability of structures.
In sum, structure of the present utility model, by not reducing fluid property and property easy for installation, by the mitigation system quality, the optimization system structure reduces the hot junction system cost, improves durability of structures.

Embodiment
For the utility model is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.
As shown in Figure 2; a kind of structure that improves turbosupercharged engine exhaust hot junction durability that provides for the utility model; comprise catalyst converter 7; in conjunction with Fig. 3; catalyst converter 7 comprises shell 7-1 and places the interior carrier 7-2 of shell 7-1; between shell 7-1 and carrier 7-2, be provided with liner 7-3, outside the inlet end of catalyst converter 7, be with inlet end protecting sheathing structure 8.The outlet side of catalyst converter 7 connects stainless solleret box structural tube 5, and stainless solleret box structural tube 5 links to each other with turbosupercharger by connecting ring 4, is provided with grooved supporting structure 6 on catalyst converter 7.
As shown in Figure 3, be liner protection structure, the inlet end of shell 7-1 begun at A place shown in Figure 3 to curve inwardly 30-60 ° until the B place, external frame position of carrier 7-2, thereby reach protective lining 7-3, avoid the purpose of being corroded by air-flow.
As shown in Figure 4, described stainless solleret box structural tube 5 is a footwear box structure 13 with the jointing of catalyst converter 7, is formed with fluid air flue face 12 on the inwall of stainless solleret box structural tube 5, is provided with projection 14 on the outer side surface of stainless solleret box structural tube 5.
Stainless solleret box structural tube 5 can be by fluid air flue face 12 control fluids, and the diameter that keeps seam crossing to avoid air-flow by footwear box structure 13 impacts simultaneously, and improves the intensity of weld seam.Projection 14 connections for other accessory structures provide platform, reduce manufacture difficulty, have also improved the intensity of pipe simultaneously.And stainless employing then reduced the quality of structure self, and its intensity at high temperature is better than the intensity of cast iron simultaneously.
As Fig. 5 and shown in Figure 6, a side of connecting ring 4 links to each other with turbosupercharger by a v-shaped structure 9, and opposite side is enclosed within by linkage structure 11 outside the end of stainless solleret box structural tube 5, and this v-shaped structure 9 is spherical sealing surface 10 with the surface of contact of turbosupercharger.Keep sealing by spherical sealing surface 10, can save sealing gasket like this.
As shown in Figure 7, on grooved supporting structure 6, be provided with positioning hole 6-1 and waist shaped hole 6-2.As shown in Figure 8, grooved supporting structure 6 is connected with shell 7-1 sealing.
