The utility model discloses an engine intake manifold which comprises a big flange (1) used for connecting a cylinder cover, a pressure-stabilizing cavity main pipe (3), a pressure-stabilizing cavity rear end cover (4) and a pressure-stabilizing cavity front tapered end (9), wherein the big flange (1) is connected with the pressure-stabilizing cavity main pipe (3) by a plurality of branch pipelines (11); every two branch pipelines (11) are connected with each other by a reinforcing rib (10); and the pressure-stabilizing cavity main pipe (3) is provided with a bracket component (2), a first boss (5), a second boss (6) and a third boss (7). After the technical scheme is adopted, the engine intake manifold provided by the utility model is simple in structure, and the weight of the engine intake manifold is approximately equal to that of a cast aluminium pipe; the engine intake manifold has the charging efficiency equal to that of a plastic intake manifold, but the cost of the engine intake manifold is about 60% of that of the plastic intake manifold, so that the cost is reduced; and carbon structural steel can be conveniently molded.
Description
Technical field
The utility model relates to a kind of engine intake manifold.
Background technique
Intake manifold is to influence engine power performance, Economy and vitals attractive in appearance, and is higher to the designing requirement of intake manifold.Require not only that line style is smooth, inner chamber is smooth, flow coefficient is high, each arm good uniformity; Pipe range, caliber ratio there is corresponding requirements; For improving constantly the competitive advantage of product,, very nearly the same on its weight with aluminum alloy having under the high volumetric efficiency prerequisite of plastic inlet pipe, replacing white metal with ferrous metal; But be to have belonged to 60% of cheap plastic inlet pipe on the price; Because of each type, vehicle type structure parameter are different, purposes is different, power character, Economy are required also inequality, on air feeder structure have a difference.Though plastic inlet pipe charging efficiency is high; But because of mould costs an arm and a leg; Be difficult to satisfy the supporting needs of different machine types, vehicle with differentiation; In order to reduce the kind of suction tude, and adopt the way of yielding to, sacrificing power character and Economy to satisfy the automobile or the engineering machinery of difference in functionality, service condition.The premium properties of plastic inlet pipe can not be given full play to.
The model utility content
The utility model problem to be solved is, to the deficiency of existing technology, and the engine intake manifold that a kind of simple in structure, convenient formation is provided, reduces cost.
To achieve these goals, the technological scheme taked of the utility model is:
This engine intake manifold that the utility model provided; Comprise the big flange, the pressure stabilizing cavity person in charge, pressure stabilizing cavity rear end cover and the pressure stabilizing cavity inner cone end that are used to connect cylinder cap; Described big flange is responsible for pressure stabilizing cavity through a plurality of pipelines and is connected; Described pipeline connects through stiffening rib between any two, on described pressure stabilizing cavity is responsible for, is provided with bracket component, first boss, second boss and the 3rd boss
Described stiffening rib is a hollow out.
Be provided with the little flange that connects throttle valve body at described pressure stabilizing cavity inner cone end.
Described intake manifold is processed by structural carbon steel.
Adopt technique scheme; This engine intake manifold that the utility model provided, simple in structure, be close with the cast aluminium pipe on the weight; Can reach the charging efficiency of plastic air intake manifold; But on cost, be 60% of plastic air intake manifold approximately, reduced cost, the convenient formation of structural carbon steel.
Description of drawings
The mark of facing down among expressed content of each width of cloth accompanying drawing of this specification and the figure is made brief description:
Fig. 1 is the structural representation of the utility model.
Be labeled as among the figure:
1, big flange, 2, bracket component, 3, pressure stabilizing cavity is responsible for, 4, the pressure stabilizing cavity rear end cover, 5, first boss, 6, second boss, the 7, the 3rd boss, 8, little flange, 9, pressure stabilizing cavity inner cone end, 10, stiffening rib, 11, a pipeline.
Embodiment
As shown in Figure 1; This engine intake manifold that the utility model provided; Comprise the big flange 1, the pressure stabilizing cavity person in charge 3, pressure stabilizing cavity rear end cover 4 and the pressure stabilizing cavity inner cone end 9 that are used to connect cylinder cap; Big flange 1 is responsible for 3 through a plurality of pipelines 11 and pressure stabilizing cavity and is connected, it is characterized in that: a pipeline 11 is between any two through stiffening rib 10 connections, on the pressure stabilizing cavity person in charge 3, is provided with bracket component 2, first boss 5, second boss 6 and the 3rd boss 7.
Adopt technique scheme, this engine intake manifold, simple in structure; Adopt structural carbon steel to process, what weight and casting aluminium material were processed is close, but charging efficiency can reach the efficient of plastic air intake manifold; But cost has only 60% of plastic air intake manifold, has reduced cost like this.
As shown in Figure 1, stiffening rib 10 is a hollow out.
Adopt technique scheme, alleviated the weight of whole intake manifold.
As shown in Figure 1, be provided with the little flange 8 that connects throttle valve body at pressure stabilizing cavity inner cone end 9.
Intake manifold is processed by structural carbon steel.
Each parts of intake manifold all are welded to connect.
Adopt technique scheme, adopt the good structural carbon steel of ductility to make the intake manifold material, utilize each arm molded lines of technique guarantee such as punching press, bend pipe to meet design requirement; On mould, open processing line, circular arc curvature smaller portions are prone to fold, slight crack etc. when avoiding bend pipe; Reduce welding stress, made things convenient for making, guaranteed normal usage requirement, each welding part of intake manifold has been optimized processing, be divided into a plurality of parts, improved the moulding of steel intake manifold, welding procedure; Pressure stabilizing cavity front end and back end, big flange 1, little flange 8 all adopt impact briquetting, to the complicated suction tude that requires is arranged individually, can adopt the welding of clampshell stamping part, satisfy the inflation performance requirement.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
