Abstract
The utility model discloses an outer shell of an air inlet manifold of an engine, which is made of plastic. The utility model is composed of a pressure-stabilizing cavity (1), four parallel air inlet bent pipes and a mounting seat (4), wherein the upper ends of the air inlet bent pipes are communicated with the pressure-stabilizing cavity (1), and the lower ends are communicated with the mounting seat (4). The air inlet bent pipes are formed by connecting front pipes (2) with back pipes (3) along a curved surface contour (5). The front ends of the front pipes (2) are communicated with the pressure-stabilizing cavity (1), and the back pipes (3) are integrated with the mounting seat (4). The utility model improves the structural defect existing in an outer shell of an air inlet manifold with integral cast by aluminum alloy. The utility model has the advantages of low cost, good strength and light weight, and raises the entire performance of the air inlet manifold.
Description
Technical field
The utility model relates to a kind of engine intake manifold, more particularly, is a kind of shell of engine intake manifold, and it is by pressure stabilizing cavity, four intake elbows and fitting seat constitute described intake elbow upper end and pressure stabilizing cavity UNICOM, lower end and fitting seat UNICOM side by side.
Background technique
The intake manifold of using on the motor car engine is a class vitals, its shell is many at present to be made with aluminum alloy material, TJFAW h type engine h intake manifold shell as a kind of public use, its structure is mainly by pressure stabilizing cavity, four intake elbows and fitting seat are formed side by side, its intake elbow upper end and pressure stabilizing cavity UNICOM, lower end and fitting seat UNICOM.This intake manifold shell is in aggregates with the aluminum alloy material casting, and its advantage is compact structure, intensity height; But existing following defective then can not be ignored:
1. also need secondary operations after the intake manifold shell integral cast moulding, as pick burr, mill and bore mill etc., increased manufacturing process and manufacture cost.
2. integral cast structure easily makes product form hidden danger of quality such as sand holes, bubble, and these latent defects will have influence on the performance of petrol engine.
3. the intake manifold shell price of aluminium alloy structure is expensive, and quality is heavy.
4. the integral cast structure of aluminum alloy air inlet manifold shell makes that the distribution of its intake elbow is unreasonable, is not uniform as it.
5. aluminum alloy air inlet manifold rough inner surface, the inlet stream dynamic resistance is big.
The model utility content
The technical problems to be solved in the utility model is to improve defectives such as the existing sand holes of prior art integral cast structure, bubble, reduce manufacture cost, alleviate intake manifold weight, provide a kind of intake elbow distributed architecture rationally, be easy to plastics air inlet manifold branch of engine shell manufacturing, light weight.
The technical solution of the utility model is summarized as follows: a kind of engine intake manifold shell, by pressure stabilizing cavity, four intake elbows and fitting seat constitute side by side, described intake elbow upper end and pressure stabilizing cavity UNICOM, lower end and base UNICOM, described intake elbow is connected to form by preceding Guan Yuhou pipe, pipe front end and pressure stabilizing cavity UNICOM before described, described back pipe constitutes one with fitting seat.
The rear end of pipe interconnects with the front end edge curved surface profile of back pipe before described, and described four intake elbows and pressure stabilizing cavity are uniform UNICOM, and described pressure stabilizing cavity is provided with stiffening rib, also is provided with stiffening rib on the described intake elbow.
The utility model compared with prior art, its superiority is embodied in following several respects:
1. the intake manifold shell mechanism is made of three parts, but the equal single injection-molded of every partial component need not secondary operations, and the member precision is good, no sand holes, no bubble.
2. the preceding pipe rear end of intake elbow interconnects with back pipe front end edge curved profile, has increased it and has connected area, join strength height, in addition, stiffening rib is set on the pressure stabilizing cavity, the overall construction intensity that stiffening rib has then increased the intake manifold shell is set on the intake elbow, and can effectively prevent distortion.
3. the plastic air intake manifold shell mechanism is reasonable, and four intake elbows evenly distribute and pressure stabilizing cavity UNICOM, make air inlet evenly, pressure stability, improved the air inlet charge.
4. the structure of engineering plastics shell, performance can match in excellence or beauty with aluminum alloy, but in light weight, low cost of manufacture.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Engine intake manifold shell of the present utility model is made of pressure stabilizing cavity 1, intake elbow and fitting seat 4, and described intake elbow is four side by side, upper end and pressure stabilizing cavity 1 UNICOM, lower end and fitting seat 4 UNICOMs; Described intake elbow is connected to form by preceding pipe 2 and back pipe 3, the front end 9 and pressure stabilizing cavity 1 UNICOM of described preceding pipe 2, and described back pipe 3 and fitting seat 4 constitute one; The intake manifold shell of present embodiment, the preceding pipe 2 of its pressure stabilizing cavity 1, intake elbow, the back pipe of intake elbow 3 and fitting seat 4 three partial component are injection molded by engineering plastics; Before the curved surface of pipe 2 rear end 7 designs, merge with the curved surface kissing of front end 8 designs of back pipe 3 and to form curved surface profile 5; Along this curved surface profile 5, the rear end 7 of preceding pipe 2 is bound up with the front end 8 of back pipe 3; The preceding pipe 2 of four intake elbows, with its front end 9 be distribution equalizing structure, front end of preceding pipe 29 and pressure stabilizing cavity 1 UNICOM; Pressure stabilizing cavity 1 is provided with stiffening rib 6; Also be provided with stiffening rib 10 on the preceding pipe 2; Be coupled to an integral body by the weldering of mill sassafras between intake manifold shell three partial component of present embodiment.
Claims (5)
