Abstract
The utility model discloses a mixed power electric passenger car APU rear transverse device relating to a configuration of the vehicle driving system, which is characterized in that the driving system comprises an electric driving system composed of a motor, a reducer, a transmission shaft, a driving axle and is arranged between beams in a same manner with the traditional vehicles; and the APU system composed of a motor and a generator is transversely arranged at the rear end to form a ''T'' with the electric driving system. The utility model shortens the rear suspension, lengthens the wheelbase, increases smoothness of the entire car, optimizes the shaft load distribution, increases 20% seating capacity under the same car length condition, reduces the mechanical transmission loss, increases the radiation efficiency and increases the economical efficiency of the entire car and can be used on city passenger car.
Description
Technical field
The utility model relates to a kind of layout of driver for vehicle, particularly horizontal set device behind the hybrid electric bus APU.
Background technology
Entered since 21st century, energy shock and environmental pollution are human two hang-ups that move ahead of puzzlement always.Particularly for the China of high speed development, petroleum import is subjected to serious restriction, and city pollution further aggravates, and the cry of building " energy conservation type ", " environment friendly " society is more and more higher.
City bus is people's the main vehicle, also is one of important source of pollution of urban atmospheric pollution.Appearing on the modern automobile development history of hybrid-power electric vehicle has milestone inthe, the tendency of the day of current " energy-conserving and environment-protective " that lead.But the serial mixed power electrobus is because the electric drive system parts are many, and APU (Auxiliary Power Unit) auxiliary power unit is difficult to arrange on car load.Adopt the arrangement of traditional passenger vehicle to be: Engine-Generator-electrical motor-retarder-transmission shaft-drive axle, so a kind of arrangement causes the car load rear overhang long, needs 3.6 meters arrangement space at least.Rear overhang is long all very unfavorable for arranging in axle load distribution and the car, and is difficult to arrange on less than 12 meters vehicle.Seriously restrict the use of series connection type hybrid power system on car load, influenced vehicle performance and whole structure.
The utility model content
In order to overcome the problem that above-mentioned prior art exists, the utility model provides horizontal set device behind a kind of hybrid electric bus APU, to improve the car load ride comfort, optimizes distribution of axle load, helps heat radiation.
The technical solution of the utility model is, horizontal set device behind the hybrid electric bus APU, the drive system that relates to passenger vehicle, it is characterized in that, in the described drive system, comprise that the power drive system that electrical motor, retarder, transmission shaft, drive axle are formed adopts the mode identical with orthodox car to be arranged in the middle of the crossbeam, the APU system that Engine-Generator is formed adopts horizontal arrangement and the power drive system in back to be " T " font and arranges.
The beneficial effects of the utility model are,
1), series connection type hybrid power system is arranged on car load needs 3.6 meters rear overhang length at least, rear overhang long for axle load distribute and car in arrange all very unfavorablely, and on less than 12 meters vehicle, be difficult to layout.After the APU system adopts the back horizontal, APU system and power drive system are T-shape and arrange, chassis rear overhang length can be controlled in 2.5 meters, make rear overhang shorten the wheelbase lengthening, improved the car load ride comfort, optimized distribution of axle load, under same vehicle commander's situation, can increase by 20% seating capacity.
2) because horizontal after the APU system, the layout of engine cooling system is simplified greatly than traditional arrangement mode, has reduced the mechanical drive loss, has improved radiating efficiency, improves the car load economy.
Description of drawings
Fig. 1 is the utility model APU system front view.
Fig. 2 is the birds-eye view of Fig. 1.
Among the figure, 1 wheel, 2 drive axles, 3 transmission shafts, 4 reductors, 5 drive motor, 6 electric air compressors, 7 electrical generators, 8 empty filters, 9 driving engines, 10 integral heat radiators.
The specific embodiment
The utility model is a kind of brand new automobile driving system, mainly is the structural arrangement in car load of serial mixed power APU system.
As shown in Figure 1 and Figure 2.
Wheel 1 installs on the drive axle 2, forms the travel driving system of vehicle, and transmission shaft 3 constitutes jointly driving system with reductor 4, and drive motor 5 connects reductor 4.Electric air compressor 6 is the compressed-air actuated suppliers of car load brake system; Empty filter 8 and integral heat radiator 10 all are the annexes of driving engine, keep the normal operation of driving engine.Driving engine 9 and electrical generator 7 are formed the APU system, are the propulsions source of car load.Above-mentioned each structural unit itself belongs to the part of prior art, but the layout of APU system is the key of the utility model innovation.
The arrangement structure that adopts is: the power drive system that electrical motor-retarder-transmission shaft-drive axle is formed adopts the mode identical with orthodox car to be arranged in the middle of the crossbeam, and the APU system that Engine-Generator is formed adopts horizontal arrangement and the power drive system in back to be " T " font and arranges.Chassis rear overhang length can be controlled in 2.5 meters, make rear overhang shorten the wheelbase lengthening, improve the car load ride comfort, optimize distribution of axle load, under same vehicle commander's situation, can increase by 20% seating capacity.
The APU system adopts horizontal another benefit that arrangement brought in back to be exactly: the layout of cooling system is simplified greatly, and the direct-connected mode of radiator fan employing driving engine has not only reduced the cooling system parts and also improved radiating efficiency.
