Abstract

The utility model relates to an intake manifold, which is a preferred matching intake manifold for petrol engine, and consists of tube bodies each having a small end flange on one end. A fixing boss is disposed on the rear lower side of the small end flange on the left end od the tube body; the upper side wall of the fixing boss is connected with the tube body wall by a narrow connection wall, while the two sides are connected with the tube body wall by a reinforced rib. The utility model has a convenient producing and casting process, effectively eliminates dispersed shrinkage casting defects and manifold local overheating abuse existing in the current technologies, obviously improves the manifold product qualified rate, ensures the product quality stability, reduces self weight, saves raw material and reduces production cost.

Description

A kind of intake manifold

Technical field

The utility model relates to a kind of petrol engine, and particularly a kind of intake manifold is a supporting intake manifold first-selected on the petrol engine.

Background technique

As everyone knows, motor is the heart of automobile, and the quality of engine performance will play crucial effects to the performance of automobile overall performance.Yet the performance of motor car engine is to be realized by the common co-ordination of each component that constitutes motor car engine, although and intake manifold is not the vitals of motor, its performance quality will produce certain influence to the performance of gas distribution system.Although intake manifold in the past can satisfy the performance requirement of use.But because the connection boss and the tube wall of its top are to be connected with each other by a solid Cylindrical object.The design of this linkage structure is unreasonable, not only increased technical difficulty, caused intake manifold in process of production the casting defect of local superheating and shrinkage porosite to occur, caused the quality instability of intake manifold to casting production process, up-to-standard rate is low, but also has increased cost of production and materials consumption.

The model utility content

The problem that the utility model exists at prior art, a kind of usage requirement of both having satisfied intake manifold has been proposed, the casting production process difficulty is reduced, effectively eliminate casting defect, the stability of improving the quality of products and product percent of pass, alleviate the intake manifold that deadweight is saved raw material and reduced production costs.

The purpose of this utility model realizes by the following technical solutions:

The body that is had small flange plate by an end is formed, and its fixing lug boss is located at downside after the left end small flange plate of body, and the upper side wall of fixing lug boss links to each other with tube body wall by narrow connecting wall, and both sides link to each other with tube body wall by stiffening rib.

Described two stiffening ribs are the both sides that splayed configuration is arranged at fixing lug boss.

The section thickness 3-5mm of described narrow connecting wall.

The utility model has the advantages of as follows:

The utility model compared with prior art, because the Placement of fixing lug boss and tube body wall is improved to the technical measures such as stiffening rib that narrow connecting wall and both sides are the splayed configuration setting, and has the production of convenience casting technique through evidence, effectively eliminate the shrinkage porosite casting defect of prior art existence and the drawback of manifold local superheating, obviously the up-to-standard rate that improves the manifold product is guaranteed constant product quality, also alleviated simultaneously deadweight, saved raw material, reduced cost of production.

Among Fig. 1,1, small flange plate, 2, fixing lug boss, 3, stiffening rib, 4, narrow connecting wall, 5, body.

Embodiment

Content of the present utility model is described in detail in conjunction with the accompanying drawings by embodiment.

As shown in Figure 1 be main TV structure schematic representation of the present utility model, the left end of body 5 is provided with small flange plate 1, fixing lug boss 2 is located at this end small flange plate 1 downside afterwards, the upside of fixing lug boss 2 fuses by the outer wall of narrow connecting wall 4 with body 5, and both sides are splayed configuration and two stiffening ribs 3 are set link to each other with body 5 outer walls.The section thickness of described narrow connecting wall 4 is 3-5mm.
