Background technology

The technical program relates to fluid mechanics, aeromechanics, and automotive enginering and medical knowledge, the utilization complex art goes to solve " energy-saving and emission-reduction " problem of city motor bus, and core technology of the present utility model is: " evade the resistance of wind and utilize wind-force "; " wind wing energy-conserving and environment-protective city motor bus " comprehensive many-sided innovative technology is formed, evade the air draught aspect: earlier from the profile improvement, four jiaos of four jiaos of headstock top to bottom, left and right, front and rear, top all use big radian the design of R angle, adopt straight line convection current large tracts of land perforate tailstock plate, tailstock lower end with parabola raise, increase drag reduction dunce cap etc.; Utilize the wind-force aspect: invent out several forms and differ, have air-flow is turned round it " flap " of function uses not to the utmost, the free from contamination energy---" air-flow " goes to fan cool and bring fresh air for rearmounted h type engine h and numerous passengers; Title is: flap, the go for a drive wing, the little wind sheltering wing for a short time, because they all are to produce power with wind, so be referred to as " wing ", the form of tool guided bone is referred to as " leading ", stream is meant " air-flow ", this is " the wind wing of resistance minimum " (hereinafter to be referred as " wind wing "), and the utility model has solved the hard nut to crack of rearmounted h type engine h passenger vehicle " machine room high temperature anoxic " and " the sultry anoxic of passenger carriage ".

History and recent developments about " engine at extreme rear passenger vehicle "; Engine at extreme rear passenger vehicle (tail type bus) is Englishman's invention the earliest, the early stage double-decker bus in Hong Kong all is to make in British Ley Land depot, driving engine is with the lucky diesel engine of taking of 150 horsepowers of Britain, last century late nineteen seventies, in order to increase passenger capacity and to improve driver's working environment, driving engine is placed on the tailstock by changing at headstock, be to name to be " jewellery type " bus at that time, because can reduce noise, reduce vibrations and reduction operator's compartment temperature and welcome by the driver, from then on, " rear-engined passenger vehicle " arises at the historic moment, propagate its belief on a large scale, but attend to one thing and lose sight of another, change the bus behind the tail type into, boiling hot gas exhaust duct crooked joint nearly (has 8 bendings more than one times than the traditional vehicle head dummy, the many more horsepower that consume more of bending), and high concentration heating, the cooling of urgent need moving air, yet air pressure and object ecophene based on the tailstock are limit, main frame and freeing pipe all are in " the static state of cooling " heat radiation very slow, therefore can be awfully hot, the freeing pipe that can not get cooling off is given main frame thermal energy transfer again, make the temperature of main frame and machine room very high, air quality very poor (these two kinds of reasons all can loss main frame horsepower), so the power phenomenon laboriously of going up a slope that descends occurred, the bus originating firm of Britain is not gone into seriously reason, but adopt the method that increases main frame horsepower to go to solve (increasing to 185～210 horsepowers) by 150 horsepowers, recent two decades comes, single-deck bus is in the world also followed this engine at extreme rear pattern, no matter but engine at extreme rear passenger vehicle horsepower size, individual layer is still double-deck, all exist machine room intake deficiency, the problem that temperature is too high, " aeromechanics " stationary gas characteristic: " gas energy high compression; temperature build-up; the strong expansion ", for the phenomenon of the too high difficult air intake of machine room of temperature has been done to explain oneself.

Diesel engine for boats is to utilize cooled with seawater fresh water, again by the fresh water cooling machine oil, because sea temperature is low, the machine room volume is also bigger, so good cooling results, diesel engine of vehicle is the 12 blade large power shaft flow fans that utilize the host vehicle head to drive, super close distance ground directly blows tank radiating plate for the main frame heat radiation, must satisfy the requirements and be, the air that circulation is arranged, but present case is: the tail machine room is very narrow, obstruction of the respiratory passage is smooth, heat-producing main frame and hi-heat freeing pipe all concentrate within 1.5 meters, heating on the heat, outside air can not advance, though the bottom of main body also can dispel the heat at the bottom of being exposed to car, owing to around be with the reason that steel plate surrounds, near air does not flow, because the certain high temperature of machine room, some bus firms removes the air admission machine room of machinery room bottom plate at the bottom of by car, but does not increase considerably windage area 2 sq ms in tailstock railway carriage or compartment as a result because of tailgate has scanty stomatal, near 28% of cross sectional area, this is 90 ° and facings the wind, and is into U-shaped, and this is the form that goes up maximum resistance in this world! The driver is forced to open tailstock plate and is exposing main frame and travel, and therefore, illustrates that installation " straight line convection current large tracts of land perforate tailstock plate " has urgency.

The problem that adopts air-conditioning to bring about passenger carriage: the nineties later stage; because the bus of old-fashioned natural ventilation only depends on roof skylight air intake; and the resistance of wind is very big; there is sultry problem summer; most of bus changes the closed windows of natural ventilation into air-conditioning; because air-conditioning compressor also will go to drive by the main frame headstock; consume main engine power and reach 20%; so engine power will increase to 240～320 horsepowers; consumes energy significantly; also increase the chance of communicate illness behind the employing air-conditioning, also given off a large amount of hot airs, made ambient air temperature raise; in addition; be well known that: the people who relies on air-conditioning fully can get " air conditioner disease " (skin function deficiency disorder, this is close to is incurable disease), and the air-conditioning deficiency of many buses; the Che Neirede picture steams Saunas; the passenger look on the bright side of things window can not, air is very muddy in the car ... above problem " wind wing energy-conserving and environment-protective city motor bus " can both solve, and sees Figure 10.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

(1) air inlet of tail machine room is bad causes hi-heat reason: because engine at extreme rear passenger vehicle " machine room admission port " changes air draught at the bottom of side air draught and the car into by the front air intake at present, the air-flow of vehicle body both sides rushes at the rear at a high speed strong during running car, air-flow all is pass each other so close that they almost rubbed each other (comprising at the bottom of the car) through admission port, pressure in the machine room is greater than the outer pressure of car at this moment, (" fluid mechanics " Bernoulli's theorem: " flow velocity is fast more; pressure is more little ") air-flow does not advance machine room, exhausr port then also is difficult for exhaust (when automobile some air of thrust air inlet eloquence inspiration by fan at a slow speed or when air pressure equates when dropping off the guests on stopping because the air-flow of outside forms brattice, so " engine at extreme rear passenger vehicle " is when travelling, all be to be under the serious condition of poor of machine room airiness to operate, because engine temperature too high, some bus carries full passenger midway and also will cast anchor to stop and add water for cooling, the water of water tank seethes with excitement, as seen the height of temperature, must make the machine room airway unobstructed, the fresh air that flows is introduced machine room, and cooling main frame and freeing pipe could address this problem at all! China is also different with the bus machine room admission port and the exhausr port pattern of foreign country at present, have their own characteristics each, the car majority that China produces is that " cooling fan blows (foreign car is opposite) to tail; the freeing pipe under the right admission port cooling car; the left side has exhausr port; tailstock plate top perforate heat-dissipation pattern (machine room is in closed state) in the majority; this pattern goes to calculate with air volume flow V (M3/S); obviously be very little, flow V is littler when running at high speed, or even zero air inlet, the automobile most of the time all is under steam behind the engine starting, calculate with 70 kilometers speed per hours, quiet wind speed degree 19 meter per seconds, machine room is not advanced in the basic suction of air of (air flows faster backward during contrary wind) tailstock, this is because the pitch of fan (the advancing speed apart from M/S of each second) is synchronously approaching with the speed that air-flow sucks, air just can not advance, fan is also brought into play less than effect, because anoxic makes main frame horsepower subtract greatly, driving engine is the heart of automobile, the temperature of machine room and level of oxygen all can influence the efficient of driving engine, driving engine operates power and descends under high temperature and airiness condition of poor, because the burning of diesel oil needs the participation of oxygen, guarantee the optimal air supply ... (see " 486 pages of diesel engine handbook, press of Shanghai Communications University), otherwise bad over-emitting black exhaust just can burn, both reduce main engine power and also caused aerial contamination, high temperature has also shortened the tenure of use of driving engine for a long time, the tail type bus that travels on the present road surface, in fact every chassis is all as carrying a continuous heat-producing big stove (heat in the tailstock, freeing pipe at the bottom of the car is warmmer), some double-decker bus is in order to reduce computer room temperature, roll up fan, refrigerating fan together with driving engine reaches 6, the increase of fan brings energy consumption and noise, however, computer room temperature is superelevation still, the deflation hole of tailstock plate has sticked the carbon dust of black, this is the bad proof of diesel combustion, reason is that air inlet is bad, the driver is reflected according to double-decker bus: " ' unable ' is even open the throttle wide; car is also unhappy ", be in fact the main frame anoxic make diesel combustion bad due to, solution: the machine room admission port adds " the wind-guiding wing " (Fig. 1) (Figure 23), can increase main frame horsepower immediately.

(2) the automobile tailgate produces eddy resistance: the automobile tailgate is the important component part of tail machine room, pore also is one of reason that causes the computer room temperature superelevation greatly inadequately: the design form of city motor bus tailgate is a lot of at present, each car manufacturer is all pursued attractive in appearance and characteristic, the higher problem less than normal of ubiquity position of opening (may be automobile design teacher all think the reason that hot air can rise), cause air inlet, the situation that exhaust is not smooth, external air will be through the bending of 90 degree, the thrust that adds electric fan could be discharged the tailstock to rising, form two kinds of resistances: 1, be reverse air resistance (most of air rushes at tailgate), 2, be to form air churning resistance (the square tailstock can form depression) behind the tailstock plate, attract ambient air (comprising the waste gas that freeing pipe is discharged), also attract vehicle body deboost backward, " be referred to as " eddy resistance " (accounting for total drag 15%) in the ship design handbook, this is to cause the open out car also to walk one of unhappy reason, see accompanying drawing 11, solution: " straight line convection current large tracts of land perforate tailstock plate " sees accompanying drawing 8, " rising tailstock energy conservation " sees accompanying drawing 9, the tailstock three binding energy of windowing significantly reduce eddy resistance, and can produce forward thrust, see accompanying drawing 8.

(3) " the water conservancy diversion wind wing " bad big problem of passenger carriage airiness when (Fig. 1) (Fig. 2) can solve running car: fresh air is one of healthy key factor of human body, old fashioned bus air-flow all is the compartment that passes each other so close that they almost rubbed each other to go into, this programme adopts " flap " (Fig. 2), " wing for a short time goes for a drive " (4) are installed in every lattice window fwd glass, the air-flow that passes each other so close that they almost rubbed each other is introduced in the compartment, the window of the tailstock is can traversing switch, opening tailstock window makes airiness better, simultaneously also can reduce eddy resistance, replace air-conditioning with " the wind wing ", it is enough that every lattice window only need be opened about 10 centimeters air quantity, both pleasantly cool, the outside noise is also little, the passenger can go the size of adjustment window to select intake and air intake angle according to the needs of oneself, can allow air-flow take away on one's body hot gas, can have a breath of fresh air again, just in case taking place, fire alarm or overturning fall also escape easily of river passenger, " the wind wing " protrudes area and only increases by 4%, the actual air resistance that produces has only 1.2%, " wind wing energy-conserving and environment-protective city motor bus branch " individual layer wind wing bus " and " double-deck wind wing bus " two classes; And individual layer wind wing bus divides " full blast aerofoil profile " and " the half wind wing, half air-conditioning-type " (front with air-conditioning back wind wing), " full blast wing double-decker bus " and " the half wind wing is transferred bus in midair " (upper strata with " the wind wing " lower floor's air-conditioning) (actual is four kinds of vehicles); Half wind aerofoil profile is to need the personage to select to some, is the design of excessive property, and the contriver believes that citizen are very fast and just can admit " full blast wing energy-conserving and environment-protective bus ", and then urban district temperature is expected to reduce by 1～2 degree centigrade, and ticket also has the downward modulation space, sees Figure 12 and Fig. 2, Fig. 4.

(4) the electric fan groove configuration design of protrusion roof: because stop " the wind wing " can not play a role, (red light, traffic congestion, on drop off the guests) immobilising problem of air when stopping in order to solve, the design does the electric fan groove for 0.3 meter in the middle body rising of individual layer bus, every chassis is installed 4 rotary electrical fans, and (every 50W * 4=200W) make air flows, switch is controlled by vehicle commander (driver).This is a kind of design of innovative form, the volume that only needs to increase seldom just can hold four rotary electrical fans, has solved the bad problem of passenger carriage airiness when stopping, and the moulding of fan groove is a streamline contour and the combining of camber line shape, be the design of windage minimum, see accompanying drawing 8, accompanying drawing 9, Figure 12.

(5) rising tailstock bottom line energy conservation: this is the energy-conservation means of a remarkable benefit: the engine at extreme rear public bus is for reason attractive in appearance at present, the afterbody lower end is all near straight, it is very little to raise, maximum air resistance form is under cover gone up in this design in this world---" the U-shaped leg ", therefore the design is played body side tail bottom line and is the parabola rising by rear wheel, 50～55 centimetres of rearmost ends (higher 19～20 centimetres) than general bus apart from ground, this design can produce five kinds of benefits: the windage area that 1, reduces tailstock plate lower end; 2, reduce tailstock eddy resistance; 3, augment tube and body heat radiation; 4, economize on material and alleviate tare; 5, the back car of driver does not worry that the tailstock bumps stone step.Design after the reform is also without detriment to good looking appearance, because stand-type can not see freeing pipe (the design painstakingly allows be exposed to gas current friction at the bottom of freeing pipe and the main frame, because cold and hot molecular friction heat radiation is just fast), this measure not only reduces the windage area and reaches 8% approximately, can also quicken the heat radiation of main frame and freeing pipe, achieve many things at one stroke, this method is referred to as: " rising tailstock bottom line energy conservation ", it may be the way of the public bus initiative in the whole world, principle is from the design experiences of boats and ships afterbody, air resistance is ground generation each second, per hour at last 3600 times, be exactly 28800 times 8 hours every days, and be 10512000 times (10,512,000 times) every year, and reducing resistance is that cost is minimum, the most profitable power-economizing method, if can be converted into its power multiplication of power to resistance, see Figure 12.

(6) silencer dunce cap: the area of section of silencer is not little, the bench section is just in the automotive wheel back, the powerful air-flow that produces facing to wheel also produces not little air resistance, and therefore the place ahead streamline contour cap of cover (dunce cap) at silencer reduces air resistance, sees Fig. 7.

This is the innovative form technology that changes the transportation means air motion, at first design for " engine at extreme rear type city motor bus " " energy-saving and emission-reduction ", invent out that multiple " the wind wing " utilizes air-flow to remove to change air circulation system (machine room and passenger carriage), replace " air-conditioning " with " air-flow " (fresh air), adopt multiple new design to remove to reduce air resistance on the other hand, on the basis of the rearmounted public bus of available engine, reform and replenish, reach significantly energy-conservation more than 30%, and the effect that can improve service quality, therefore be referred to as: wind wing energy-conserving and environment-protective city motor bus "; the technical program is fit to new car and builds; the local flow improvement of the new and old engine at extreme rear public bus that is more suitable for operating, and also is applicable to the machine room admission port of boats and ships; window; the cooling air intake vent of exhaust chimney and the push-pull type window of some building are installed.

(1) Fig. 1-2 flap: " streamline contour " of approximate " fluid mechanics ", aspect ratio is different with cross section shape, also different with " airfoil type " aspect ratio, radian, the cross section shape of " aeromechanics ", be to come out, overlook the shape of seeing picture 1/2 water droplet according to the speed of automobile and the position research and design of admission port.

(2) Fig. 3-4 wing that goes for a drive for a short time: the engine at extreme rear public bus of old-fashioned natural ventilation only depends on roof skylight air intake, and the resistance of wind is very big, the design is only protruded about 2～3 centimetres of vehicle body both sides, the wind wing of 35 °～45 is down with the wind arranged, two sidewinds are cut in the machine room admission port and compartment, Fig. 3 is installed in the rear of vehicle body both sides machine room admission port, and Fig. 4 is installed in window glass the place ahead of body-side.

This wing that goes for a drive for a short time is installed in the rear of vehicle body both sides machine room admission port, principle is: protrude vehicle body and have the wind wing of 35 °～45 down with the wind for about 2～3 li, air-flow is cut into machine room admission port, in order to prevent with the passing of time to be out of shape, also have the spy to make L shaped pressing plate (hereinafter to be referred as " pressing plate ") up and down, push down air-flow and enter and seal and block rainwater, can also see Figure 12 by additional strengthening (installation method is the same) durable in use.

This wing that goes for a drive for a short time is installed in passenger carriage, the front end of a glass of every lattice glass port fwd, the engine at extreme rear public bus of old-fashioned natural ventilation only depends on roof skylight air intake, and the resistance of wind is very big, this programme feature is: protrude the vehicle body both sides and have the wind wing of 35 °～45 down with the wind for about 2～3 centimetres, two sidewinds are cut in the machine room admission port and compartment, (Fig. 3) be installed in the rear of vehicle body both sides machine room admission port, (Fig. 4) be installed in window glass the place ahead of body-side.

This wing that goes for a drive for a short time is installed in the place ahead of vehicle body one side machine room exhausr port, " wing for a short time goes for a drive " counter-rotating is oppositely used, just become " the little wind sheltering wing ", its principle of work is: " the little wind sheltering wing " utilizes 35～miter angle to separate the brattice that air-flow forms, shape is caused depression on the exhausr port limit, allowing hot gas discharge vehicle body easily allows air-flow take away outward, whether need to install " the little wind sheltering wing ", depend on the main frame cooling fan towards, if the main frame cooling fan is backwards, " the little wind sheltering wing " need not be installed, and " the little wind sheltering wing " is on one side be particularly suitable for the used car transformation that air inlet is on one side given vent to anger.

This admission port is designed to protrude and can goes for a drive outside the vehicle body into interior vertical miter angle barrier, this is a kind of method, act on identical with " wing for a short time goes for a drive ", but air draught and friction drag can be big, can reinstate the steel manufacturing together with barrier one, this method is fit to new car builds, and " the wind wing " is fit to the admission port barrier perforate (vertical, level, circle) of any pattern, but as can not pacify anti-direction with " vertical louver oblique angle barrier ".The front end of this silencer dunce cap causes streamline contour, then can reduce some air resistance as processing difficulties at the place ahead of silencer and the fuel tank that exposes swept-out cap of cover, make dunce cap as non-metal and will open two louvres up and down, material can be used steel, corrosion-resistant steel, fireproof glass epoxy manufacturing.

Can see the form of distinguished " straight line convection current large tracts of land perforate tailstock plate ", protrude the configuration design of electric fan groove, the position of electric fan, openable tailstock window and the employing " rising tailstock energy conservation " of roof.

Can see " flap, the stream plate of pulling; machine room admission port and freeing pipe cooling air intake vent, the energy-conservation parabola of the rising tailstock; semi-open glass port; " used car transformation " not necessarily will adopt new design all; as long as local the employing also has remarkable benefit, for example: only Fig. 1 " the water conservancy diversion wind wing " is positioned on the machine room admission port, driving engine is just more strong than originally immediately; certainly, and it is also big more to adopt power-economizing method to overcharge benefit more.

The design makes the afterbody of car significantly reduce eddy resistance, and makes it to become propelling thrust, and this is the design of new car.

This is a width of cloth body contour design drawing, is again machine room plan; Can see the line style of vehicle body smoothness, about headstock, about, four jiaos of front and back, the four jiaos of R angle designs of all using big radian in top, can reduce the strength resistance effectively, tailstock lower end is with the parabola drag reduction that raises, the machine room admission port, " the wind-guiding wing ", for a short time the wing goes for a drive, the silencer dunce cap, semi-open vehicle window, before the window " the wind-guiding wing " that energy air inducing is gone into the compartment, there are four electric fans the top, compartment, also have machine room to arrange and exclusive " air flue " etc., this figure represents that profile is main, profile still, most importantly be: the reform that the air circulation system of people and driving engine is creative, this is without air-conditioning, but utilizes " wind energy " to fan new and improved automobile cool and increase fresh air " energy-saving and emission-reduction " for driving engine and numerous passengers.
