Abstract
The utility model relates to a component in engine intake system for vehicle, in particular to an improved intake flat tube for heavy truck, which is characterized in that the inlet end of the flat tube is provided with an eddying tube assembly comprising an outer baffle, an inner baffle and eddying tube units, after connecting, the outer baffle and the inner baffle are mounted at the inlet end of the flat tube and the joined outer baffle and inner baffle are provided with a plurality of eddying tube units. For the inlet end of the flat tube is provided with the eddying tube assembly which has the function of filtering dust, the intake flat tube improved by the proposal ensures that the flat tube bears the task of primary air filter of an air filter, thus improving the air filter rate and being conducive to the normal running of the engine and prolonging the service life. The utility model has reasonable structure, being an improvement which is conducive to improving the air filtering effect of the intake system of the engine.
Description
Technical field
The utility model relates to the parts in the automotive engine air intake system, particularly about the improved air inlet flat tube of a kind of heavy-duty car.
Background technique
A kind of suction tude of heavy-duty car is arranged at the back of operator cabin, mostly this suction tude is a kind of flat siphunculus of global formation, be provided with filter screen at the suction port end, the purpose of this filter screen and effect mainly are to stop leaf, weeds and other foreign material etc., because the bore of filter screen is bigger, so improved air inlet flat tube does not have effect of preventing and effect for the dust of diameter smaller particles shape etc.Therefore, the filtering action effect of the air inlet flat tube of this structure is relatively poor, and impairs the normal operation and the working life thereof of motor.
The model utility content
The purpose of this utility model provides the improved air inlet flat tube of a kind of heavy-duty car, in order to improve the degree of filtration of existing heavy-duty car air inlet flat tube.
For realizing this purpose, the utility model adopts following technological scheme: the improved air inlet flat tube of a kind of heavy-duty car, the suction port end that it is characterized in that the air inlet flat tube is provided with the cyclone tube assembly, the cyclone tube assembly is made up of exterior siding, internal baffle and swirling flow unit, inside and outside baffle plate engages the suction port end that the back edge is assigned in the air inlet flat tube, and the inside and outside baffle arrange-ment behind the joint has several cyclone tube unit; Inside and outside baffle plate is made as the box body of opening respectively, and the mouth-to-mouth joint of inside and outside baffle plate box body becomes the chamber of a hollow, and the plate face of inside and outside baffle plate is respectively equipped with several relative holes; The cyclone tube unit is made up of collar extension and internal orifice, and collar extension is installed on the set hole of exterior siding plate face, and collar extension is made of barrel shell and guide vane, and guide vane is located at the suction port of barrel shell, and the center has the hole at the bottom of the shell of barrel shell; The hole that internal orifice is offered by internal baffle plate face is inserted, and the inlet end of internal orifice is inserted the center hole of barrel shell bottom; The lower end of exterior siding is provided with dust exhaust port; The evenly distributed plate face that is laid in inside and outside baffle plate in cyclone tube unit.
Press the improved air inlet flat tube that such scheme is implemented, because inlet end being provided with at the air inlet flat tube has the cyclone tube assembly that filters the dust effect, make the air inlet flat tube bear the empty filter task of the first order of air-strainer, therefore not only improved empty filter rate, and helped the normal operation of motor and increase the service life.The utility model is rational in infrastructure, is a kind of useful improvement.
Description of drawings
Fig. 1 is a Facad structure schematic representation of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the enlarged diagram of B portion among Fig. 2.
Embodiment
Be described in further detail in conjunction with the accompanying drawings.Suction port end edge at air inlet flat tube 1 has been put cyclone tube assembly 2, cyclone tube assembly 2 is made up of exterior siding 21, internal baffle 22 and cyclone tube unit 20, internal baffle 22 and exterior siding 21 are made a kind of rectangular opening box respectively, and inside and outside baffle plate fastens the chamber that the back forms a hollow relatively.Internal baffle 22 behind the fastening, exterior siding 21 disposes several cyclone tube unit 20, in order to install the cyclone tube unit, interior, the plate face of exterior siding is respectively equipped with several relative holes (220,210), promptly to be the made hole 220 of internal baffle 22 relative with the made hole of exterior siding 21 210 and should be coaxial, cyclone tube unit 20 is made up of collar extension 201 and internal orifice 203, collar extension 201 is installed on the made hole 210 of exterior siding 21, collar extension 20 is made of barrel shell 202 and guide vane 2011, guide vane 2011 is fixedly arranged in the suction port of barrel shell 202, and the center has hole 2020 at the bottom of the shell of barrel shell 202.The hole 220 that internal orifice 203 is offered by the plate face of internal baffle 22 is inserted, and the inlet end of internal orifice 203 is inserted the center hole 2020 of barrel shell 202 bottoms.The lower end of exterior siding 21 is provided with dust exhaust port 3, in order to the collection and the discharge of air dust behind the guide vane eddy flow.The effect of cyclone tube is when air quilt " suction ", flow air is through guide vane the time relatively, because reversing of blade makes the air-flow that sucks produce relative rotational flow, the air-flow of rotation can will be inhaled into dust in air or other foreign material " get rid of ", and discharge through dust exhaust port 3 the top-down bottom that falls to cyclone tube assembly 2 in the box-like chamber that dust impurity etc. are buckled into along inside and outside baffle plate.The quantity of cyclone tube unit 20 is to come design apparatus according to the size of engine power, and it is more that the air inlet flat tube that engine power is big can install the quantity of cyclone tube unit 20, otherwise, 20 can install less in cyclone tube unit.Reasonable in design, the reliable and stable work of this cyclone tube assembly, this embodiment are provided with 3 rows totally 30 cyclone tube unit 20, and cyclone tube unit 20 arrangement uniformly is arranged at inside and outside baffle plate.
