Point.Purifying vehicle exhaust silencer can form condensed water during cooling, in acid (containing sulfurous acid, nitrous acid etc.).Acid
Property condensed water is accumulated in the chamber of silencer, can be aggravated the corrosion of silencer, be caused the end cap on automotive muffler machine to be present
Tool connects untight phenomenon, end cap existing defects in terms of buffer mechanism vibrations and stable silencer.
The content of the invention
In view of this, the end cap the present invention is directed to propose a kind of pair that can lift damping performance disappears, can be lifted end cap with
Mechanically connect compactness between automotive muffler, ensure the stabilization between end cap and silencer, and can buffer mechanism vibrations, carry
Rise automobilism efficiency.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of pair that can lift damping performance disappears end cap, includes the end cap body of integral die-cast shaping, the end cap sheet
The oval die mould of body, the end cap mouth of up/down perforation being provided with the end cap body, the end cap mouth is provided with yielding rubber circle,
Special-shaped neck is additionally provided with the end cap body, the left and right side of the end cap body is arranged to the buckle flange of concave arc,
Arc angle corresponding to the buckle flange is 70 ° to 80 °, and the rear and front end of the end cap body is provided with claw, the claw pair
The arc angle answered is 50 ° to 60 °.
Further, it is embedded with rubber washer in the buckle flange.
Further, the outer surface of the end cap body is coated with zinc film layer.
Further, the special-shaped neck is compressing, and the special-shaped neck is that layer enters gradually deep formula indent.
Relative to prior art, the pair of the present invention that can the lift damping performance end cap that disappears has the advantage that：
The end cap body of the present invention is oval die mould, the shape of the shape adaptation automotive muffler of itself, and end cap sheet
The end cap mouth that body is provided with corresponds to fixed part prominent on automotive muffler, and fixed part can held by interference fit, clip
Cover intraoral, and hold the yielding rubber circle of cover port to lift cushioning effect, lift the vibrations pooling feature of end cap body, it is special-shaped
Neck is that layer enters gradually deep formula indent, the inner groovy that can be adapted on silencer, is bonded inner groovy, lifts the compactness of connection, end
The buckle flange and claw that lid body is provided with, it is capable of the edge of inside clamping silencer, lifts the compactness of connection, rubber
Packing ring, shock-absorbing function can be lifted.
