Advantage of the present invention is:
1, this passenger vehicle Appropriate application space of car body, is provided with altogether four casees electrokinetic cells, thus makes electrokinetic cell total volume reach 62Kwh, substantially increase the course continuation mileage of pure electric coach, make passenger vehicle continual mileage reach 175 km.High pressure annex passenger vehicle with relatively high risk is arranged in the afterbody of car body simultaneously, and access door is set at hull back, both improve the safety of car load, facilitate again and car inner component is overhauled.
2, the right side of described car body is provided with high-voltage charging mouth, and the charging duration of described four casees electrokinetic cells is shortened greatly, is full of and only needs 3-6 hour.
3, high-tension battery is lifted on below vehicle frame, allows car load crossbeam vehicle frame can form good protection to high-tension battery, prevents to greatest extent, because vehicle rear-end collision, the battery extrusion caused that scratches damage, extruding on fire.
4, the vehicle body and the frame section that form car body all adopt three layers of fire protection design, even if battery burns, passenger inside the vehicle also has sufficient time escape.
5, this medium bus of the present invention had both employed electronic type of drive, in turn ensure that dynamic property and the safety of passenger vehicle, had also taken into account the traveling comfort taken simultaneously, and good looking appearance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the front view that this direct connection of the embodiment of the present invention drives pure electronic medium bus;
Fig. 2 is the upward view that this direct connection of the embodiment of the present invention drives pure electronic medium bus;
Wherein: 1-car body, 2-propons, 3-back axle, 4-front-wheel, 5-trailing wheel, 6-access door, 7-high-voltage charging mouth, 8-electrokinetic cell, 9-electric inflation pump, 10-storage battery storehouse, 11-electric powered steering pump.
Detailed description of the invention
Fig. 1 and Fig. 2 shows this direct connection of the present invention and drives a specific embodiment of pure electronic medium bus, and this center passenger vehicle comprises car body 1, be loaded on propons 2 on this car body and back axle 3, be loaded on the front-wheel 4 at described propons two ends, be loaded on the trailing wheel 5 at described back axle two ends, for driving the drive motor of described front-wheel or rear wheel and providing the electrokinetic cell 8 of electric energy for described drive motor.Described car body 1 is made up of the vehicle body on top and the vehicle frame of bottom.
The key improvements of the present embodiment is: described electrokinetic cell 8 has four casees, and these four casees electrokinetic cells are all lifted on below described vehicle frame.All high pressure annexes on this passenger vehicle are arranged in (comprising high-pressure modular) rear (being also the afterbody of car body 1) of back axle 3, and the afterbody of car body 1 is provided with access door 6.
The space of car body due to this passenger vehicle Appropriate application, be provided with altogether four casees electrokinetic cells 8, thus make electrokinetic cell total volume reach 62Kwh, substantially increase the course continuation mileage of pure electric coach, make passenger vehicle continual mileage reach 172km, can meet run short-distance requirement as medium bus completely.High pressure annex passenger vehicle with relatively high risk is arranged in the afterbody of car body 1 simultaneously, and access door is set at hull back, both improve the safety of car load, facilitate again and described high pressure annex is overhauled.High-tension battery is lifted on below vehicle frame, allows car load crossbeam vehicle frame can form good protection to high-tension battery, prevents to greatest extent, because vehicle rear-end collision, the battery extrusion caused that scratches damage, extruding on fire.
In this example, described drive motor is the rearmounted rear-guard motor of associated mode, and be extra large lattice motor, the deceleration subtracted by control motor speed and back axle master is increased turns round the driving realizing car load, travels smooth-going, rotating speed is high, reserve power is large, and nominal torque is excellent, continues hill climbing ability strong, starting, acceleration are all steady than traditional passenger vehicle, and noise is also far smaller than orthodox car.Whole-control system, power system have Self-Integration ability, easily can upgrade efficiently in the future, safeguard, past-sale service.
And this example in the left side of described car body 1, be provided with high-voltage charging mouth 7 in the rear of described back axle 3, car body 1 is provided with the overhead door that can block described high-voltage charging mouth 7.During practical application, open this overhead door and namely charge to described electrokinetic cell 8 by high-voltage charging mouth 7.The setting of this high-voltage charging mouth 7, makes the charging duration of described four casees electrokinetic cells 8 greatly shorten, and is full of and only needs 3-6 hour.
The profile of this passenger vehicle carries out development and Design on the basis in the special moulding of Cowes, and its outward appearance is exquisite elegant, and transforms passenger-carrying chassis layout, ensure that the safety of electrokinetic cell.The vehicle body and the frame section that form car body all adopt three layers of fire protection design, even if battery burns, passenger inside the vehicle also has sufficient time escape.
Car body 1 is provided with the electric inflation pump 9 being positioned at described back axle 3 rear and the electric powered steering pump 11 being positioned at described propons 2 rear.Wherein electric inflation pump 9 provides source of the gas for passenger vehicle, and electric powered steering pump 11 provides power steering, adjusts bus driving direction to assist chaufeur.
In addition, this example is also provided with low pressure storage battery 10 bottom described car body 1, for powering to low-voltage electrical elements such as room light lamps.
Certainly, above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to people can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to the Spirit Essence of main technical schemes of the present invention or modification, all should be encompassed within protection scope of the present invention.
