Abstract
The utility model discloses an exhaust front pipe with enough layout space for the exhaust system of vehicle, and is characterized in that the exhaust front pipe of vehicle connects with an exhaust manifold of an engine has a flat structure. The exhaust manifold can have enough layout space by the structure, and meanwhile the flexural rigidity of the exhaust manifold in Y direction is reduced, and plays the role of compensation in the greater displacement of the exhaust system and the part is not go as far as being damaged. The utility model can reduce the rigidity of the vibration noise system and improve the reliability and durability of the product by the corrugated pipe provided at front end of the exhaust front pipe assembly used as the flexible joint.
Description
Technical field
The utility model relates to field of automobile, more specifically to managing before a kind of exhaust that can make the automobile exhaust system assembly obtain enough arrangement space.
Background technology
Existing automobile exhaust system assembly is managed before mainly comprising exhaust, manage the back, clean-up device, noise silencer etc.Pipe mostly is to adopt the cylinder steel pipe before the exhaust, and camber even " detouring " layout of relying on the engineer to repeat to revise pipe under the space-constrained situation of chassis often obtain suitable installing space, wastes time and energy uncertainly can obtain good effect.
Summary of the invention
Technical problem to be solved in the utility model is managed before providing a kind of vehicle exhaust emissions that can make the automobile exhaust system assembly obtain enough arrangement space.
The scheme of the utility model technical solution problem is: be flat-shaped structure with pipe before the engine exhaust manifold bonded assembly vehicle exhaust emissions.
The front end of pipe arranges that bellows is as flexible hinge before the above-mentioned exhaust.The rigidity of vibration noise system be can reduce like this, reliability of products and durability improved.
The flat-shaped structure of pipe posterior segment under change speed gear box, passing through before the above-mentioned exhaust: is 400 ± 5mm from the flat-shaped preceding pipe that passes through under the change speed gear box from the change speed gear box front end to rear end flange connections length, height 25 ± 3mm, the flat tube of width 60 ± 3mm.Can make spatial destribution become simple and handy.
Pipe adopts the stainless steel tube that flattens before the above-mentioned exhaust.
Thereby the utility model will be owing to will adopt the stainless steel tube that flattens to make preceding pipe obtain enough arrangement space with pipe before the exhaust of engine exhaust manifold bonded assembly.Pipe is in the bending stiffness of automobile Y direction before reducing simultaneously, redeeming when exhaust system has very big displacement and be unlikely to part and be damaged.If the front end of pipe assembly before the exhaust is arranged that bellows is as flexible hinge.The rigidity of vibration noise system be can reduce, reliability of products and durability improved.
Description of drawings
Fig. 1 is the preceding pipe assembly structural representation of the exhaust among the embodiment.
Fig. 2 is that the A of Fig. 1 is to view.
Among the figure: 1, pipe before the exhaust, 2, bellows, 3, the flat tube section of pipe before the exhaust, 4, the back end flanges.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The specific embodiment
Among the embodiment, the preceding end spaces of pipe 1 is bigger before the exhaust, reduces the rigidity of vibration noise system at this location arrangements bellows 2 as flexible hinge, improves reliability of products and durability.Bellows 2 is connected and fixed by the dontake pipe of exhaust flange and driving engine, adopts stainless steel tube with pipe before the exhaust of engine exhaust manifold bonded assembly.Preceding pipe posterior segment is the flat tube section of pipe before the exhaust, and it passes through under change speed gear box, and this position is minimum in the vertical direction space, if adopt the pipe of φ 50 to produce interference with change speed gear box.Pipeline section from the bending flattening to back end flanges 4 about 400mm length is pressed into high 25mm, and after the flat tube 3 of wide 60mm, it is simple and handy that spatial destribution becomes.
Claims (5)
1, pipe before the exhaust in the exhaust system of automobile is characterized in that: be flat-shaped structure with pipe (1) before the engine exhaust manifold bonded assembly vehicle exhaust emissions.
2, pipe before the exhaust according to claim 1 is characterized in that: the front end of pipe arranges that bellows (2) is as flexible hinge before the above-mentioned exhaust.
3, pipe before the exhaust according to claim 1 is characterized in that: the flat-shaped structure of pipe posterior segment (3) for passing through under change speed gear box before the above-mentioned exhaust.
4, pipe before the exhaust according to claim 3 is characterized in that: is 400 ± 5mm from the change speed gear box front end to end flanges (4) junction, back length from the flat-shaped preceding pipe (3) that passes through under the change speed gear box, height 25 ± 3mm, the flat tube of width 60 ± 3mm.
5, pipe before the exhaust according to claim 1, it is characterized in that: pipe adopts the stainless steel tube that flattens before the exhaust.
