Abstract

The utility model provides a turbocharged cast iron exhaust manifold additional strengthening. The problem of do not set up additional strengthening, the poor technique of steadiness under the extreme condition of big heating load between present each exhaust branch of engine exhaust manifold is solved. Its technical essential is: four exhaust branch entrance points set up side by side connects inlet flange, front side transverse connection outlet(discharge) flange is held in joiing of four exhaust branch, converge the side surface setting of end back by converging many the exhaust manifold body strengthening ribs of end to the radial transverse distribution of four exhaust branch, four boss deep floor s with inlet flange terminal surface being the symmetrical direction setting of 45 degree contained angles are provided with at the exhaust manifold support boss outer wall near joiing the end, the strengthening rib that is the V font in many manifold body strengthening ribs is connected with an adjacent boss deep floor formula as an organic whole. It can effectually prevent stress concentration, guarantees exhaust manifold reliability and durability, and is safe firm, long service life.

Description

A kind of turbosupercharging cast-iron exhaust manifold strengthens structure

Technical field

The utility model relates to automobile engine to exhaust device, and particularly a kind of turbosupercharging cast-iron exhaust manifold strengthens structure.

Background technique

Along with automobile market is increasingly competitive, higher performance, lower oil consumption, less discharge, 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.At present, without reinforcement structure between each exhaust branch pipe of existing automobile gas exhausting manifold branch, fragile, causing potential safety hazard, 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 turbosupercharging cast-iron exhaust manifold and strengthens structure.Solve between each exhaust branch pipe of available engine gas exhaust manifold and reinforcement structure is not set, the technical problem of steadiness difference under the mal-condition of large heat load.It can effectively ensure gas exhaust manifold reliability and durability, securely, and long service life.

The technological scheme that the utility model adopts is: this turbosupercharging cast-iron exhaust manifold is strengthened structure and comprised outlet(discharge) flange, four exhaust branch pipes and inlet flange, its technological points is: described four exhaust branch pipe entrance points are set up in parallel connection inlet flange, lateral connection outlet(discharge) flange on front side of the merging end of four exhaust branch pipes, arrange by many gas exhaust manifold body stiffening ribs of merging end to the radial transverse distribution of four exhaust branch pipes at merging end rear side surface, strengthen gusset being provided with four boss that the symmetry direction that is 45 degree of angles with inlet flange end face arranges near the gas exhaust manifold bracket bosses outer wall of merging end, gusset strengthened by the stiffening rib be in the shape of the letter V in many manifold body stiffening ribs and adjacent boss is that integral type is connected.

The advantage that the utility model has and good effect are: because the utility model is strengthened the four-in-one position that gas exhaust manifold is heated the highest by the gas exhaust manifold body stiffening rib that many are arranged in exhaust branch pipe surface; Gas exhaust manifold bracket bosses is strengthened gusset and is played the reinforcement of gas exhaust manifold entirety fixing, article four, boss is strengthened gusset and inlet flange end face and is miter angle direction and arranges, the force direction being subject to gas exhaust manifold support due to gas exhaust manifold bracket bosses is perpendicular to direction, inlet flange face, be 45 degree of dispersions being furnished with the power of being beneficial to by stiffening rib and Impact direction, prevent stress from concentrating; Second reinforcement gusset and adjacent boss are strengthened gusset and are connected as one.These two groups of stiffening rib knot positions are stress deathtrap, and it is that integral type is connected that V-shaped bar manifold body stiffening rib and adjacent boss are strengthened gusset, the stress in the interval of having evaded two groups of stiffening ribs.Therefore, ensure gas exhaust manifold reliability and durability by above structure, securely, long service 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;

Fig. 2 is the A portion enlarged view of Fig. 1.

In figure, sequence number illustrates: the stiffening rib of gusset, 5 gas exhaust manifold bracket bosses, 6 inlet flanges, 7V font strengthened by 1 exhaust branch pipe, 2 gas exhaust manifold body stiffening ribs, 3 outlet(discharge) flanges, 4 boss.

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 and Fig. 2, as shown in Figure 1, embodiment is: a kind of turbosupercharging cast-iron exhaust manifold strengthens structure, comprise outlet(discharge) flange 3, four exhaust branch pipes 1 and inlet flange 7, four exhaust branch pipe entrance points are set up in parallel and connect inlet flange 6, lateral connection outlet(discharge) flange 3 on front side of the merging end of four exhaust branch pipes, arrange by many gas exhaust manifold body stiffening ribs 2 of merging end to the radial transverse distribution of four exhaust branch pipes at merging end rear side surface, this merging end is that gas exhaust manifold is heated the highest position, these many gas exhaust manifold body stiffening ribs are made up of the stiffening rib of three layers of lateral arrangement, the superiors are yi word pattern stiffening rib, the second layer is the stiffening rib 7 in V-shape, bottom is two stiffening ribs of arranging corresponding to upper strata stiffening rib hypotenuse, gussets 4 strengthened by four boss being provided with symmetry direction setting at gas exhaust manifold bracket bosses 5 outer wall near merging end, article four, boss is strengthened gusset 4 and is 45 degree of angle directions with inlet flange 6 end face and arranges, the force direction being subject to gas exhaust manifold support due to gas exhaust manifold bracket bosses is perpendicular to direction, inlet flange face, be the dispersion that miter angle is furnished with the power of being beneficial to by stiffening rib and Impact direction, prevent stress from concentrating.Gusset strengthened by stiffening rib 7 and adjacent boss of V-shape is that integral type is connected, the stress in the interval of having evaded two groups of stiffening ribs.
