Description
Technical field
The utility model belongs to the automotive transmission field and relates to a kind of super-low floor airport ferry bus driving rear axle that adopts brand-new gate-type dependent suspension wheel motor as driving.
Background technology
Along with China's air freight industry fast speed development, substituting traditional airport ferry bus with super-low floor, modernization and oligosaprobic novel airport ferry bus is a kind of trend, traditional airport ferry bus drives for the twins diesel engine, purpose for the super-low floor that satisfies vehicle body, diesel engine must be as on the vehicle body and take 4 meters long carrying zone, simultaneously the exhaust emission of diesel engine and the environmental demands that noise pollution does not meet modern airport.
In order to overcome above these defectives, the utility model proposes a kind of super-low floor airport ferry bus driving rear axle, what this driving rear axle adopted is the driving of brand-new gate-type dependent suspension wheel motor as airport ferry-boat vehicle, utilize this driving rear axle can increase about 4 meters long of the carrying space of ferry bus, with this driving rear axle serves as that the airport swing car that make on the basis is compared with traditional airport ferry bus of equal length, the seating capacity can be increased to 120 people from 80 people, simultaneously also reduced exhaust emission under the condition of super-low floor satisfying, noise pollution and wearing and tearing, present domestic this similar product that also do not have, our design plan of at first proposing in the world to use the single shaft low section tyre to replace traditional twins on big 13 tons of driving rear axle of airport ferry bus in 2000 at home, cause very big reaction outward, become new trend now.It has played impetus for the improvement of low floor airport ferry bus.
Summary of the invention
The utility model technical issues that need to address are, the environmental demands that does not meet modern airport at the exhaust emission and the noise pollution of diesel engine in the prior art and provide a kind of: super-low floor airport ferry bus adopts single shaft to carry 13 tons on this driving rear axle with driving rear axle, super flat single tire, with the super-low floor airport ferry bus driving rear axle of non-independent wheel limit drive motor as the drive source formation, utilize this bridge can make the wide 1260mm of reaching of passage of the airport ferry bus of manufacturing, adopt super low section tyre can make only 240mm of ferry bus floor, airport terrain clearance; Wearing and tearing have been reduced; Reduction ratio reaches 23.95 decelerations of satisfying high-speed electric expreess locomotive and increases and turn round requirement, and wheel motor drives the designing requirement of having satisfied big drop, makes and reduced exhaust emission and noise pollution again when satisfying the low floor requirement.
Technical solution adopted in the utility model is:
A kind of super-low floor airport ferry bus driving rear axle, include back bridge grider, wheel limit drive motor, wheel reduction gear, hub reduction case, disc type brake, super flat single tire and air suspension, described airport ferry bus driving rear axle is a kind of big drop gate-type dependent suspension wheel motor drive axle, the hub reduction case is equipped with in bridge grider both sides, described back, the hub reduction case is connected with wheel limit drive motor, the hub reduction case is gone back the fifth wheel side reducer simultaneously, and super flat single tire is housed on the bridge.The width of described back axle is the flat axle housing bodies of the special-purpose back axle of 3 meters overall width passenger vehicles, and super flat single tire is adopted in 13 tons of single shaft carryings, with tire line of centers drop be 245mm.The wheel motor of back axle, wheel reduction gear and drop-gear box are formed the both sides that drive line is assemblied in driving rear axle, and wheel reduction gear and drop-gear box total reduction gear ratio are 23.95.
The beneficial effects of the utility model are:
1, the wheel motor drive configuration is simple, the mechanical efficiency height.The wheel motor drive axle has been cancelled driving engine and whole annex such as power-transfer clutch, change speed gear box and the transmission shaft of orthodox car, main reduction gear, diff and semiaxis on the conventional drive bridge have been cancelled simultaneously, wheel reduction gear that the substitute is small size directly links to each other with drive motor, simple in structure, save installing space, improved machinery driving efficiency.Adopt the wheel motor of alternating current impression formula to be fixed on the rear driving axle both sides, reduced the vibrations that produce because of traditional motor, reduced mechanical wear.The pulse free moment of torsion.
2, this drive axle adopts super low section tyre, big drop, flat axle housing and adjustment height air suspension, therefore the airport ferry bus visitor who utilizes this rear driving axle to make reaches the super-low floor requirement, passenger getting on/off body whole descend (two cars are gone down on one's kness), the floor is liftoff high 240mm, concordant with the step of waiting, can make passenger getting on/off convenient and safe.It is constant to make the floor terrain clearance remain on 340mm by steam pocket inflation in travelling.Guarantee the unmanned and horizontal and vertical gradient in full Che Chenei floor simultaneously.
3, the airport ferry bus that utilizes this driving back vehicle bridge to make has super wide passage, superpower circulating capacity, because compact design, provide the low floor height, bigger take the space in, also realized passenger passageway in the wideer car, twins becomes single tire makes the quiet width of passage at back axle place reach 1240mm, and the wide drive axle of traditional 3m has only the 800mm gangway width.Can make the full Che Chenei of airport ferry bus floor not have the vertical and horizontal gradient, guarantee the passenger's circulation and the safety of standing.These have guaranteed superpower rapid evacuation and circulating capacity, can under any circumstance guarantee passenger safety, easily and fast with comfortable.
4, super flat single tire of the height to width ratio 0.45 of this rear driving axle installation, load-carrying capacity is strong, 13 tons of single tire axle loads, tire-contact area is big, friction is little, adhesive ability big, do not have sideslip, (the both sides motor movement is not relatively independent because of differential causes extra skimming wear, two wheel drag differences, automatically realize rotating speed separately, no rigidity diff, therefore slip is almost 0), the effect that can play the noise reduction sound and prolong the service life of tire, only the back axle deadweight is with regard to about 100kg that descends, and rolling resistance descends 15%, makes the also corresponding reduction of oil consumption therefore play the purpose of fuel-economizing.
5, because this bridge of waiting has guaranteed that super-low floor and Che Nei do not have any vertical and horizontal gradient, more do not have step, motor is arranged under the back axle floor simultaneously, so arranges easily the area utilization height in the car.And motor has reached high area utilization, the super large capacity of tourists in the hardship that the back axle driver no longer is subjected to the baking of driving engine, sultry, vibrations, pollution and noise.
