Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
The exhaust pipe assembly 100 according to the utility model embodiment is described in detail below in conjunction with accompanying drawing.
Shown in seeing figures.1.and.2, comprise downtake pipe 1, second exhaust pipe 2, outer male member 5, flanging 6, sealing gasket 3 and clip 4 according to the exhaust pipe assembly 100 of the utility model embodiment.
Specifically, downtake pipe 1 and second exhaust pipe 2 are coaxially arranged, and the second end of the first end of downtake pipe 1 and second exhaust pipe 2 is towards relative.On the first end that outer male member 5 is located at downtake pipe 1 and extending radially outwardly along downtake pipe 1.Outer male member 5 is formed as annular.For convenience of describing, the one side towards downtake pipe 1 of outer male member 5 is defined as the first wall below, the one side towards second exhaust pipe 2 of outer male member 5 is fixed as the second wall.
Flanging 6 is located on the second end of second exhaust pipe 2.Flanging 6 is formed as annular and the axial cross section of flanging 6 comprises the first limit 61 and Second Edge 62.First limit 61 is connected with the second end of second exhaust pipe 2, and Second Edge 62 only supports on the second wall of outer male member 5.Between the second wall that sealing gasket 3 is located at outer male member 5 and Second Edge 62.Clip 4 is fastened on the first wall and Second Edge 62.
In brief, downtake pipe 1, second exhaust pipe 2, outer male member 5, flanging 6, sealing gasket 3 and clip 4 is comprised according to the exhaust pipe assembly 100 of the utility model embodiment.The first end of downtake pipe 1 is connected with the second end of second exhaust pipe 2.Outer male member 5 is located at the first end of downtake pipe 1, and flanging 6 is located at the second end of second exhaust pipe 2.Outer male member 5 forms tapered face fit structure with flanging 6, and sealing gasket 3 is clipped in this cone match place, and fastening with clip 4, thus realizes connection and the sealing of two outlet pipes.
According to the exhaust pipe assembly 100 of the utility model embodiment, by arranging sealing gasket 3 between male member 5 and flanging 6 outside, and adopt the fixing outer male member 5 of clip 4 and flanging 6, make downtake pipe 1 and second exhaust pipe 2 can realize being tightly connected by cone match, improve the sealing of cooperation place, connection sealing between downtake pipe 1 and second exhaust pipe 2 is good, and reliability is high, effectively prevent joint because of urea liquid and leaks the urea crystals problem caused.
According to the exhaust pipe assembly 100 of the utility model embodiment, abandon traditional plane docking contact Connecting format, have employed a kind of novel cone match and connect.As everyone knows, for the pipeline having certain pressure intensity, equal pressure divided by area according to pressure, when pressure is certain, the less pressure of sealing area is little, therefore more easily seals.And the advantage of cone match is linear sealing, reduces the area of contact of sealing surface, therefore, the sealing of joint is improved.Meanwhile, the use of clip 4 ensure that the reliable connection of joint.
The utility model solves the sealing problem of the joint of heavily card high-temperature exhaust pipe, eliminates the urea crystals that state four vehicle causes because outlet pipe leaks.
According to embodiments more of the present utility model, sealing gasket 3 is graphite grazing pad 3.The graphite grazing pad 3 of same thickness and copper sealing gasket 3 are under same function power, and the decrement distortion of graphite grazing pad 3 is larger than the compress variation of copper sealing gasket 3.Therefore, compared with the copper sealing gasket 3 of employing, graphite grazing pad 3 can have larger decrement, therefore more easily seals, good sealing effect.
As shown in Figure 2, one end of the contiguous downtake pipe 1 of the first wall is provided with joint, and joint is connected with downtake pipe 1, and extends along the circumference of downtake pipe 1.Alternatively, the cross section of outer male member 5 is formed as the V-type of opening towards the axis of downtake pipe 1; Or the cross section of outer male member 5 is formed as the trapezoidal of a side opening, and opening is towards the axis of downtake pipe 1.As shown in Figure 2, the joint rounding off of the first wall and the second wall.
Flanging 6 comprises the first limit 61 and Second Edge 62.First limit 61 extends along the axis of second exhaust pipe 2, and Second Edge 62 tilts to extend along the radially outward of second exhaust pipe 2.Angle between Second Edge 62 and the first limit 61 is obtuse angle.Thus, Second Edge 62 can be fitted on the second wall of outer male member 5 preferably.Alternatively, the joint rounding off of the first limit 61 and Second Edge 62.
Alternatively, flanging 6 and outer male member 5 are formed as metalwork respectively.Outer male member 5 is weldingly connected with downtake pipe 1, and flanging 6 and second exhaust pipe 2 are weldingly connected.Be understandable that, the Placement between outer male member 5 and downtake pipe 1 and the Placement between flanging 6 and second exhaust pipe 2 are not limited only to the mode be weldingly connected, and also can adopt other Placements.
Such as, in reality manufactures, for convenience of manufacturing and assembling, outer male member 5 can be formed as one part with downtake pipe 1, and flanging 6 and second exhaust pipe 2 can be formed as one part.
Clip 4 is formed as annular and the axial cross section of clip 4 is formed as the trapezoidal of a side opening.Conveniently assemble, clip 4 can be formed as multiple arcuate segment, and multiple arcuate segment joins end to end the clip 4 of looping, is connected to the cone match place of outer male member 5 and flanging 6.
In a word, according to the exhaust pipe assembly 100 of the embodiment of the present invention, sealing gasket 3 can realize the sealing between downtake pipe 1 and second exhaust pipe 2; Clip 4 can realize the connection reliability between downtake pipe 1 and second exhaust pipe 2; Outer male member 5 and flanging 6 coordinate with sealing gasket 3, sealability is improved greatly, effectively prevent joint and occur that urea liquid is revealed.
The exhaust pipe assembly 100 according to the utility model embodiment is comprised according to the automobile of the utility model embodiment.This exhaust pipe assembly 100 can adopt the linkage structure in correlation technique with the linkage structure of miscellaneous part on automobile.Owing to there is above-mentioned useful technique effect according to the exhaust pipe assembly 100 of the utility model embodiment, therefore improve according to the sealing of the automobile of the utility model embodiment, the joint of outlet pipe can be avoided to occur urea crystals problem.
