Description
Technical field
The present invention relates to the air inlet system of a kind of passenger vehicle, belong to bus body technical field, particularly relate to a kind of preposition
Air inlet system on motivation passenger vehicle, is specifically useful on the basis of being exclusively used in bus with front-mounted engine, improves entering of air inlet system
Wind efficiency, and strengthen its versatility.
Background technology
In recent years, dynamic property and the economy of electromotor are more and more important to the development of passenger vehicle, promote the power of electromotor
Property the most increasingly comes into one's own.Air inlet system for the adequacy of engine system fuel combustion, air inlet cleannes, and for
The importance of the protection of electromotor is more and more obvious.In terms of air inlet system, air filter, before accurately filtering, needs
One can be filtered rainwater, leaves etc. compared with bigger material or the device of heavier granule, and the air making entrance air filter is more clear
Clean, to increase air filter maintenance period, this matching requirements possesses good filtration effect, simple for production, low cost, the spy such as is easily installed
Point, on way-train, employing air filter air inlet box is to realize this function, but existing air filter air inlet box is generally welded to car load gusset,
Not only volume is relatively big, has big and obvious protruding parts, and filter effect is the best, additionally, cost of manufacture is higher, installs and examines
Repair cleaning inconvenience, be more difficult to application particularly with prepositive engine coach.
Chinese patent, Authorization Notice No. is CN202319880U, and authorized announcement date is the utility model on July 11st, 2012
Patent discloses a kind of air inlet channel structure of air filter of passenger car, including body frame and vehicle body outer covering, vehicle body outer covering offers

The top of the nearly door skin 71 of grid 1 is arranged.
The principle of the present invention is described as follows:
(1), rear air inlet unit 2, advancing air unit 3:
Present invention is mainly used for prepositive engine coach, the agent structure of its air inlet system described is by rear air inlet unit 2, advance
Wind unit 3 forms, and during application, external wind enters epimere air channel 7 from air-inlet grille 1, ties subsequently into advancing air passage 8(core
Structure is advancing air unit 3), after transition enters, air intake passage 9(core texture is rear air inlet unit 2), then by rear air inlet unit 2
Rear air intake base plate 25, air filter connecting plate 101 enter air filter 10, finally by between air filter 10 and electromotor
Pipeline enter electromotor.
Therefore, the design the combination of advancing air unit 3, rear air inlet unit 2 is regarded as a kind of integration module, constitute
One independent assembly, the wind outside side car can not only well guide to air filter 10 by it, more crucially it
Do not limited by position relative between air-inlet grille 1 and air filter 10, it is easy to existing body structure (gusset, floor)
Being combined, thin portion structure can be adjusted flexibly according to particular location, easily realize installing with fixing, structure versatility is extremely strong, the most not
Taking the space in existing car, compatibility is stronger.
Advancing air unit 3, rear air inlet unit 2 mounting means various, as first rear air inlet unit 2 supported to gusset, connect
On connected floor frame 4, then by the air channel of air inlet unit 2 after the air channel alignment of advancing air unit 3, advance herein
Wind unit 3 and floor frame 4, use between side wall frame 5 and panel beating and be welded to connect, and front air outlet 82 and rear air inlet 91 it
Between in view of property easy for installation and fastness, use the technique of first bonding staking again (first to stick with glue knot together, then enter with rivet
Row is mechanically connected, to reinforce), this technique had both added the sealing of air inlet, the most well reduced the generation of noise, wherein
For ensureing the stability connected, use multiple rivet (preferably six rivets) uniformly staking.Additionally, air inlet unit after mounting
When 2, the present invention better profits from structure interval and carries out the layout of air inlet system, to increase the arrangement space of interior of body seat,
The position making driver's chair 14 first row passenger seat 15 below is unrestricted, and as shown in figure 13, rear air intake top board 21 is Z-type
Structure, has a knuckle design, thus increases the distance between first row passenger seat 15 and preceding object, be equivalent to increase
The space of seat can be arranged, row's seat can be arranged more, and for passenger vehicle, under identical parking lot, seat number is many more
There is competitiveness.
(2), advancing air unit 3:
Advancing air unit 3 includes outside advancing air base plate 31 and advancing air interior plate 32 connected vertically with its dual-side, advancing air
Side plate 33. wherein, base plate the first connecting plate 311 that advancing air base plate 31 includes being sequentially connected with, base plate the second connecting plate 312, the end
Plate the 3rd connecting plate 313 and base plate the 4th connecting plate 314, by its link position, the design of connection angle so that it is overall in
It is now the ramp structure of a kind of lower extension, additionally, the junction that connecting plate is the most each other is all the transition structure (plate of circular arc
And being to seamlessly transit between plate, belong to arc transition, a monoblock base plate can be by one flat plate bending and forming, it is also possible to be punching
Molded, if with if welding, existing for corner angle, the situation of its gas flowing does not has the good of arc transition), when wind enters from the external world
Enter, by when flowing in the passage become folded by advancing air base plate 31, advancing air interior plate 32, advancing air outer panel 33 arrow Suo Shi
(seeing Fig. 5), external wind pressure is big, and wind is certain to be to walk from top to bottom, the most not the barrier structure such as partition, again can be by means of tiltedly
Slope and designed arc-shaped appearance produce guiding function to wind, thus well guide the trend of air-flow, improve the air intake effect of air filter
Rate.
(3), various plates:
Have employed multiple, the plate of Multiple Shape in rear air inlet unit 2, advancing air unit 3, the parameter of plate is (such as shape, length and width
High, ornaments angle etc.) it is the vehicle and unique design applied based on it, main consideration tire is beated, intake, air-conditioner pipe
Road connects and overhauls the impact of convenience etc., and owing to intake requires, so each may be affected air intake effect
The cross section that the plate of fruit is constituted all must assure that area of section is at least 1.5 times of air filter 10 incoming air area.For
The vehicle of other front-mounted engines outside disclosed in the design, can be carried out detailed structure based on this mentality of designing flexibly
Changing, this will be apparent from, and falls under the scope of the present invention.Rear air intake header board 22 is made up of flat board, and it is opened
If rear air inlet 91 be rectangle.Various plates can be made by welding, bending, three kinds of modes of punch forming, and material can
To be steel or fiberglass.
(4), drainage belt:
Drainage belt 252 is made up of rubber or thin plastics, and external port is flat mouth, use twitch one's mouth structure enable to outside air and
Dust be not easy due in air channel negative pressure and enter in air channel by drainage belt 252, drainage belt 252 for draining, ash discharge, with
Time avoid because of in air channel negative pressure and make pipeline gray back.
