Tube body one end be equipped with the first flange that connect with booster, the tube body side is connect equipped with multiple with engine cylinder cover
Second flange is having multiple peaces for being used to install silencer with also integrally disposed on the tube body of the opposite facing side of the second flange
Seat is filled, is respectively equipped on the tube body on the tube body between the two neighboring mounting base, between first flange and mounting base by it
The connection convex ribs that connect, the reinforcement for arc-shaped shapes arrangement that they are connected is equipped between the two neighboring second flange
Convex ribs are additionally provided with multiple grooves axially arranged along it in the tube body.
As a further improvement, side vertical protrusion of the connection convex ribs along tube body, the mounting base pass through
Connection convex ribs are connected with the tube body, and the mounting base is I-shaped structure.
Further, the corresponding flange hole reverse side of each second flange is equipped with fixed lug, which takes
Son is connected by a connecting seat with the tube body.
Further, the position of the attachment base is corresponding with the position of the groove, and the attachment base with it is described
Groove be arranged with the shape.
Further, the groove is arranged close to the corresponding inboard wall of tube body of the second flange, and the groove court
The first flange arc extends.
Further, the tube body and the first flange, second flange, connect convex ribs, reinforce convex ribs, groove it
Between be integrally formed structures.
Beneficial effect
The utility model compared with prior art, has the advantage that are as follows:
1, the exhaust pipe of the utility model, it is compact-sized, convenient for assembly, cleverly the installation of silencer is integrally disposed in
On exhaust pipe, it is consistent the vibration frequency of silencer and engine, to reduce the failure of booster, exhaust pipe fracture
Rate, and effectively increase the rigid of exhaust pipe, extends the service life of exhaust pipe, have design rationally, characteristics of compact layout,
The high feature of connection reliability；
2, the utility model carries out flow-disturbing to gas by adding groove in tube body, while can also reduce gas resistance
Power accelerates gas flow rates.
