Abstract
The utility model provides a strenghthened type cast iron exhaust manifold has solved the technical problem that present engine exhaust manifold had damaged under the abominable operational environment of high heating load. The fourth jar exhaust branch is the entrance point and sets up side by side, four exhaust branch that the exit end converges, and inlet flange is provided with provided groove through the cutting, and this provided groove is being provided with exhaust branch 1 respectively with inlet flange interval cheng yusi four bibliographic categories's branch that the exhaust branch entry corresponds between an exhaust branch and the 2nd exhaust branch and between the 3rd exhaust branch and the fourth exhaust branch, and exhaust branch 1 is connected with inlet flange and locates the just circular excessive connecting hole of adoption at provided groove. Provided groove will release partial deflection in order to reduce stress, can shift the round hole to deep floor from the manifold body with the stress danger area that heat altered shape produced to the homodisperse does not produce the stress concentration point on the round hole circumference, thereby has avoided destruction cast iron exhaust manifold firm, and the durability is higher, has prolonged life.
Description
Technical field
The utility model relates to automobile engine to exhaust device, is particularly applied to a kind of reinforced iron gas exhaust manifold of automobile with small output volumn motor.
Background technique
At present, automobile becomes staple commodities and enters into huge numbers of families.This just makes higher performance, lower oil consumption, less discharge, and better travelling comfort becomes the deciding factor determining a automobile product success or not.In order to reach these objects, usually adopting the motor of small displacement, then using reinforcement technique to promote its performance.But the engine heat load brought thus increases greatly, motor row temperature raises day by day.Gas exhaust manifold is as the main heating part of motor and even car load, and its working environment is thereupon more severe, and heat load constantly increases.Therefore, under the environment that existing enmgine exhaust constantly increases in heat load, being very easily damaged, for ensureing its working life, the task of top priority being become to the reinforcement of exhaust manifold structure intensity.
Summary of the invention
The purpose of this utility model is to provide a kind of reinforced iron gas exhaust manifold, solves the technical problem that available engine gas exhaust manifold has damaged under the harsh environments of high heat load.It adopts the cast-iron exhaust manifold with improving reinforcing rib structure, and can effectively prevent high load on the impact of gas exhaust manifold, firm firm, durability is higher, extends working life.
The technological scheme that the utility model adopts is: this reinforced iron gas exhaust manifold comprises outlet(discharge) flange, four cylinder exhaust branch pipe and inlet flanges, its technological points is: described four cylinder exhaust branch pipes are that entrance point is set up in parallel, four exhaust branch pipes that outlet end converges, inlet flange is provided with preformed groove by cutting, inlet flange is partitioned into four parts corresponding with four exhaust branch pipe entrances by this preformed groove, reinforcement gusset is respectively arranged with between first row gas branch pipe and second row gas branch pipe and between the 3rd exhaust branch pipe and the 4th exhaust branch pipe, strengthen gusset be connected with inlet flange and adopt positive circular excessively attachment hole at preformed groove place.
Described preformed groove width is 4 millimeters.
The advantage that the utility model has and good effect are: because inlet flange of the present utility model is provided with preformed groove by cutting, inlet flange is partitioned into four parts corresponding with four exhaust branch pipe entrances by this preformed groove, when after gas exhaust manifold temperature distortion, preformed groove by release portion amount of deformation to reduce stress; Reinforcement gusset is respectively arranged with between the exhaust branch pipe of both sides, strengthen gusset be connected with inlet flange and adopt positive circular excessively attachment hole at preformed groove place, the stress deathtrap that thermal distortion can be produced is transferred to from manifold body strengthens gusset circular hole, and be dispersed in circular hole circumferentially, do not produce stress concentration point, thus avoid destruction generation, therefore, it is possible to effectively prevent high load to the damage of gas exhaust manifold, firm firm, durability is higher, extends working life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
In figure, sequence number illustrates: 1 outlet(discharge) flange, 2 first row gas branch pipes, 3 second row gas branch pipes, 4 the 3rd exhaust branch pipes and 5 the 4th exhaust branch pipe arms, 6 strengthen gusset, 7 inlet flanges, 8 excessive attachment holes, 9 preformed grooves.
Embodiment
In order to make the utility model easy to understand, concrete structure of the present utility model is described in detail according to Fig. 1, embodiment comprises outlet(discharge) flange 1, four cylinder exhaust branch pipe and inlet flange 7 for this reinforced iron gas exhaust manifold, described four cylinder exhaust branch pipes are that entrance point is set up in parallel, four exhaust branch pipes that outlet end converges, four exhaust branch pipes are arranged in juxtaposition and are respectively first row gas branch pipe 2, second row gas branch pipe 3, the 3rd exhaust branch pipe 4 and the 4th exhaust branch pipe 5.Inlet flange 7 is provided with preformed groove 9 by cutting, and the optimum width of preformed groove is 4 millimeters, can effectively release portion amount of deformation to reduce stress.Inlet flange 7 is partitioned into four parts corresponding with four exhaust branch pipe entrances by preformed groove 9, be respectively arranged with between first row gas branch pipe 2 and second row gas branch pipe 3 and between the 3rd exhaust branch pipe 4 and the 4th exhaust branch pipe 5 and strengthen gusset 6, strengthen gusset be connected with inlet flange 7 and adopt positive circular excessively attachment hole 8 at preformed groove 9 place, this structure can effectively prevent high load to the damage of gas exhaust manifold.
Claims (2)
1. a reinforced iron gas exhaust manifold, it comprises outlet(discharge) flange, four cylinder exhaust branch pipe and inlet flanges, it is characterized in that: described four cylinder exhaust branch pipes are that entrance point is set up in parallel, four exhaust branch pipes that outlet end converges, inlet flange is provided with preformed groove by cutting, inlet flange is partitioned into four parts corresponding with four exhaust branch pipe entrances by this preformed groove, reinforcement gusset is respectively arranged with between first row gas branch pipe and second row gas branch pipe and between the 3rd exhaust branch pipe and the 4th exhaust branch pipe, strengthen gusset be connected with inlet flange and adopt positive circular excessively attachment hole at preformed groove place.
