Specific embodiment
With reference to specific embodiment, the invention will be further described.
This with regulatory function exhaust manifold, it include exhaust side pipe 2, bellows 3, anchor ear 6, exhaust intervalve 7 with
Ripple pipe flange 8；It is vented the rearward end of intervalve 7 and is connected with pipe flange 7.3 in the middle of exhaust, pipe flange in the middle of exhaust
7.3 inner circle is provided with step 7.1 in middle pipe flange, the cylindrical outside of step 7.1 in pipe flange in the middle of correspondence
The rear end face of pipe flange 7.3 is provided with along pipe flange fin 7.2, bellows in the middle of its circumferentially disposed exhaust in the middle of exhaust
Outside diameter of the inner circle of flange 8 with diameter greater than pipe flange fin 7.2 in the middle of exhaust；It is machined with the leading section of exhaust side pipe 2
The first outer step of exhaust side pipe 2.1 and the second outer step of exhaust side pipe 2.2, the second outer step of exhaust side pipe 2.2 is in coaxially connected
In the front end of the first outer step of exhaust side pipe 2.1, the outside diameter of the first outer step of exhaust side pipe 2.1 is more than exhaust side pipe second
The outside diameter of outer step 2.2, the rearward end of bellows 3 is cylindrical be fixed on the first outer step of exhaust side pipe 2.1 it is cylindrical on, ripple
The cylindrical inner circle with ripple pipe flange 8 in leading section of line pipe 3 is mutually fixed, and the leading section of bellows 3 is retracted the interior of ripple pipe flange 8
One segment distance of circle, the outside diameter of the second outer step of exhaust side pipe 2.2 is less than circular diameter, exhaust side in the rearward end of bellows 3
The front end face of the second outer step of pipe 2.2 stretches out the inner circle leading section of ripple pipe flange 8 and stretches into step 7.1 in middle pipe flange
The segment distance of inside one, exhaust in the middle of pipe flange 7.3 be connected by anchor ear 6 with ripple pipe flange 8, exhaust the between outer land of side pipe second
