Loaded in middle vertical section, and exhaust pipe positioning section and exhaust pipe mouth point are welding as one, and the inferior pyramidal section is used for fixed to exhaust pipe
Position section carries out blocking limit, forms trigonum between the upper conical section and exhaust pipe positioning section, is fitted in trigonum
Gasket.
As a further solution of the present invention: the supported flange is installed on the outside of middle vertical section, the upper conical section
For carrying out blocking limit to supported flange.
As a further solution of the present invention: after the supported flange and engine exhaust port are connected and fixed, exhaust pipe is fixed
The upper end of position section is located in engine exhaust port, and gasket and engine exhaust port against.
As a further solution of the present invention: the gasket is installed between upper conical section and exhaust pipe positioning section and is formed
Trigonum on after, the upper surface of gasket is located on the upside of the upper surface of upper conical section.
A kind of commercial vehicle, including the novel commercial vehicle exhaust port.
Compared with prior art, the beneficial effects of the present invention are: the novel commercial vehicle exhaust port, it is first to use pipe end
First hydro-forming is inserted into a section exhaust pipe positioning section, is then welding as one the two point, simple process, reliable performance,
Good product consistency；Welding deformation and welding stress are eliminated using the exhaust port of this structure, maximally reduce material
Reduced performance problem caused by material is denaturalized, and improve the consistency and leakproofness of product.
Detailed description of the invention
