Abstract
The utility model discloses a welded muffler for a vehicle. The welded muffler comprises a shell body, end covers arranged on two ends of the shell body, and a muffler internal resistance in the shell body. A through hole communicated with the muffler internal resistance is arranged in each end cover, a connecting fold edge is arranged on the outer periphery of each end cover, and the connecting fold edge is inserted into the shell body to be connected with the shell body in a welding manner. By the adoption of an end cover insertion type structure, the muffler is connected with the shell body in a welding manner, so that a same muffling capacity is reached, and the muffler is provided with a higher material utilization rate at the same time. The muffler has a simple design structure and a high material utilization rate, and the cost of the muffler can be greatly lowered.
Description
Technical field
The utility model relates to the silencing apparatus of automobile exhaust system, refers to particularly a kind of Automobile Welding formula silencing apparatus.
Background technique
At present, the silencing apparatus of automobile exhaust system mainly is divided into regular shape and irregular shape.The main moulding process of silencing apparatus for regular shape (having circle, ellipse, square prismatic shapes) is seaming technique.
The housing of silencing apparatus is connected with end cap through repeatedly adopting the seaming mode to connect behind the crimping.Because this Placement needs repeatedly crimping, stock utilization is not high, and the cost of silencing apparatus is higher.In addition, unavoidably have little gap between resistor and the housing between end cap and the housing, in the silencing apparatus, the rigidity of housing is not high enough, and the gap can cause radiated noise larger.
Summary of the invention
The purpose of this utility model will overcome the existing deficiency of prior art exactly, and a kind of lower-cost Automobile Welding formula silencing apparatus is provided.
For achieving the above object, the Automobile Welding formula silencing apparatus that the utility model is designed, the end cap and the interior resistor of the silencing apparatus in the housing that comprise housing, housing two ends, described end cap is provided with the through hole that is communicated with resistor in the silencing apparatus, the outer rim of described end cap is provided with the connection flanging, and described connection flanging inserts in the housing and with welding manner and is connected with housing.
In the such scheme, described housing is to connect moulding with welding manner behind the Metal Sheet in Curling.Like this, can improve the stock utilization of silencing apparatus.
Resistor comprises hush tube and is arranged on the outer dividing plate of hush tube in the described silencing apparatus, described dividing plate and housing drive fit, and connect in the spot welding mode.Like this, carry out connection between dividing plate and the housing with spot welding, to improve the rigidity of housing, reduce radiated noise.
The beneficial effects of the utility model are: adopt end cap plug in construction and housing to be welded to connect, have higher stock utilization reaching in the situation of same noise elimination volume.The project organization of the utility model silencing apparatus is simple, and the stock utilization of silencing apparatus is high, and the cost of silencing apparatus can reduce greatly.
