Want the generation of Crack prevention, conventional technological means has 3 points: the one, the wall thickness of whole gas exhaust manifold is carried out to Integral upset, and this obviously wastes material and increases complete vehicle weight, and fuel economy is had a negative impact; The 2nd, reduce the transition radian between air intake branch, but be subject to car load influence of arrangement, radian changes limited, can not thoroughly solve problem of stress concentration; The 3rd, stiffening rib is set near confluence, when concentrating, solution stress not only saves material but also be not subject to car load influence of arrangement like this.But, the design randomness of general stiffening rib is larger, does not consider near the difference of the stressing conditions in confluence, and therefore the design for stiffening rib still exists improved space, thereby the structure that makes stiffening rib meets near stress distribution feature confluence, thereby further saves material.
Model utility content
The purpose of this utility model is when solving confluence problem of stress concentration, the structure of stiffening rib is further optimized, thereby made stiffening rib meet near stress distribution confluence, saves material and cost.
For achieving the above object, embodiment of the present utility model provides following technological scheme:
A kind of gas exhaust manifold, described gas exhaust manifold has a plurality of air intake branches, a collecting pipe and a steam outlet pipe, described air intake branch, described steam outlet pipe are all communicated with described collecting pipe, described steam outlet pipe is between two adjacent described air intake branches, thereby form confluence between two adjacent described air intake branches and described steam outlet pipe, between two adjacent described air intake branches, have stiffening rib, and the width of stiffening rib increases gradually towards the direction of described confluence.
Preferably, the width that collects the stiffening rib of the more side of the air intake branch number of air-flow to described confluence collects the less side of the air intake branch number of the air-flow width of stiffening rib than to described confluence is large.
Preferably, the thickness of described stiffening rib starts to increase gradually towards the direction of confluence from the end of described stiffening rib.
Preferably, the Thickness Ratio that collects the stiffening rib of the more side of the air intake branch number of air-flow to described confluence the collects thickness of stiffening rib from the less side of the air intake branch number of air-flow to described confluence is large.
Preferably, the suction port of described air intake branch is oval.
The utility model also provides a kind of motor, and gas exhaust manifold as above is installed on described motor.
In the utility model, the width of stiffening rib increases towards confluence direction, and this meets nearer apart from confluence, the stress distribution law that stress is larger, thus with material still less, solve problem of stress concentration.In like manner, the increase gradually of Rib Thickness also meets nearer apart from confluence, the stress distribution law that stress is larger, thus with material still less, solve problem of stress concentration.
Further, the stiffening rib width of homonymy is different, and the stiffening rib of air inlet one side that collects more air intake branches is wider, and this meets the larger regularity of distribution of the more lateral stress of air inlet, thereby solves problem of stress concentration with material still less.In like manner, the stiffening rib of air inlet one side that collects more air intake branches is thicker, and this meets the larger regularity of distribution of the more lateral stress of air inlet, thereby solves problem of stress concentration with material still less.
The utility model makes under the condition that meets engine back pressure requirement overall weight lighter.

Embodiment
In the application's context, although be the gas exhaust manifold with four air intake branches be that example is described, this can not think the restriction to air intake branch number, the quantity of air intake branch can corresponding cylinder number and is changed.
As shown in Figure 1, enmgine exhaust 100 is for discharging engine exhaust, in the present embodiment, gas exhaust manifold 100 has the first air intake branch 110, the second air intake branch 120, the 3rd air intake branch 130, the 4th air intake branch 140 is totally four air intake branches, a collecting pipe 150 and a steam outlet pipe 160, the first air intake branch 110, the second air intake branch 120, the 3rd air intake branch 130, the 4th air intake branch 140 and steam outlet pipe 160 are all communicated with collecting pipe 150, like this, the waste gas that comes from a plurality of cylinders is flowed to collecting pipe 150 and finally from steam outlet pipe 160, discharges after each air intake branch.Steam outlet pipe 160 is between the 3rd air intake branch 130 and the 4th air intake branch 140, like this, crossover sites between two adjacent air intake branches (i.e. the 3rd air intake branch 130, the 4th air intake branch 140) and steam outlet pipe 160 has just formed confluence A, all gas this confluence of all can flowing through.And the suction port of the first air intake branch 110, the second air intake branch 120, the 3rd air intake branch 130, the 4th air intake branch 140 is ellipse.
With reference to figure 2, the figure shows near structure confluence A in the present embodiment, simultaneously for clear, in Fig. 2, with dotted line, expressed near tube wall profile confluence A of the prior art simultaneously.Visible, near the A of confluence, left side pipe thickness w1, right side pipe thickness w2 is obviously greater than prior art, in other words at the 3rd adjacent air intake branch 130, between the 4th air intake branch 140, there is semi-moon shaped stiffening rib 170, and the left side of the direction since the 3rd air intake branch 130 towards confluence A pipe thickness w1 increases gradually, direction right side pipe thickness w2 since the 4th air intake branch 140 towards confluence A also increases gradually, at A place, confluence, thickness reaches maximum value, that is to say, the width of stiffening rib 170 increases gradually towards the direction of confluence A, this meets nearer apart from confluence A, the stress distribution law that stress is larger, thereby solve problem of stress concentration with material still less.And due to the left side at confluence A, there is the first air intake branch 110, the second air intake branch 120 and the 3rd air intake branch 130, and on the right side of confluence A, only there is the 4th air intake branch 140, that is to say that the left side of confluence A collects the air-flow of three air intake branches, and the air-flow of an air intake branch is only collected on right side, therefore the left side stress of confluence A is greater than right side stress, as preferably, the thickness of w1 will be higher than the thickness of w2, in other words, the width of the left side stiffening rib of confluence A is larger than the stiffening rib width on right side, this meets the larger regularity of distribution of the more lateral stress of air inlet, thereby solve problem of stress concentration with material still less, realized the optimization of stiffening rib.
