Specific embodiment
Below in conjunction with the drawings and specific embodiments, the hybrid electric drive system of a kind of single shaft front-engine rear-drive of the present invention is further described.
As it is shown in figure 1, the technical scheme of the hybrid electric drive system of a kind of single shaft front-engine rear-drive of the present invention is: include electromotor 1, first clutch 2, second clutch 4, motor 3, variator 5 and drive back axle 7；Described electromotor 1, described first clutch 2, described second clutch 4, described motor 3 and described variator 5 are arranged at described Vehicular body front, and described driving back axle 7 is arranged on described rear vehicle；The both ends of described motor 3 are respectively equipped with rotating shaft, and the described rotating shaft of described motor 3 leading section is connected with described electromotor 1 by described first clutch 2, and the described rotating shaft of described motor 3 rearward end is connected with described variator 5 by described second clutch 4；Described variator 5 other end is connected with described driving back axle 7 by power transmission shaft 6.So, adopt an electric motor starting electromotor and drive wheels travel, and connect clutch respectively at the two ends of the front and back twin shaft of a motor, utilize the combination of first, second clutch duty, realize coupling and the mode of operation switching of car load power, meet the driving dynamics sexual demand under automobile difference operating mode.And adopt the cascaded structure of two motors in prior art can not meet the driving dynamics sexual demand under automobile difference operating mode.And the application is compared with the cascaded structure adopting two motors in prior art, eliminates a motor and both provided cost savings, and motor can be passed through and drive traveling, reach the purpose of oil-saving discharging-reducing.And the driving dynamics sexual demand under automobile difference operating mode be in the prior art in parallel or connection in series-parallel mixed structure could realize, and the application adopts a motor 3 and adopts single shaft arrangement, just it is sufficient for the driving dynamics sexual demand under above-mentioned automobile difference operating mode.Further, needing to occupy with parallel connection of the prior art or connection in series-parallel mixed structure on a large amount of length of wagon direction and compared with the insied width director space of cabin, the single shaft of the application drives structure only need to occupy the space on length of wagon direction；Save the arrangement space of motor, further simplify the connection between motor and each part, meet the driving dynamics sexual demand under automobile difference operating mode.Meanwhile, parallel-connection structure of the prior art, electromotor and motor the preposition forerunner of axle or engine behind front wheel forerunner, motor postposition rear-guard, so the layout of car load and body structure are required height；And connection in series-parallel mixed structure needs multiple motors, the space that drive system uses is big；And the application by by electromotor and motor preposition at Vehicular body front, and drive back axle rearmounted at rear vehicle, make full use of space longitudinal before and after car load, reduce the difficulty of arrangement, save car load space.Concrete automobile difference operating mode and driving mode are as follows: (1) disconnects when first clutch 2, when second clutch 4 closes, vehicle can be driven to travel by motor 3；So, it is not necessary to internal combustion engine start drives vehicle, arrive fuel-economizing purpose, " zero " discharge of tail gas, more environmental protection when driving.(2) when first clutch 2 closes, and second clutch 4 closes, so, when running car needs higher power, can being simultaneously driven vehicle by electromotor 1 and motor 3 and travel, motor 3 can play the function of auxiliary power；, and, when electromotor 1 has excess energy time, motor 3 can be passed through and generate electricity to battery pack charging, reduce energy loss.(3) when first clutch 2 close, second clutch 4 disconnect time, automobile is in parked state；So, electromotor 1 can generate electricity by drive motor 3, and the energy of electromotor 1 is passed to battery bag, it is achieved parking charge function, improves the utilization rate of the energy of electromotor 1 when parking.(4) when first clutch 2 disconnects, and second clutch 4 closes, automobile is in on-position, motor 3 work generating, it is achieved regenerative braking energy feedback.Therefore, can according to different demands for control, it is achieved different hybrid power drive patterns.
Referring to accompanying drawing 1, the hybrid electric drive system of a kind of single shaft front-engine rear-drive of the present invention is on the basis of technique scheme, may is that described electromotor 1 and described first clutch 2 are integrally disposed in enging cabin 8, described variator 5 and described second clutch 4 are integrally disposed in variator cabin 9.So, by integrally disposed, structure is compacter, and install simple and reliable, transmission is effective and less costly.It is preferred that technical scheme may is that described motor 3 is connected with battery bag by controller.So, the dump energy at electromotor 1 can be passed through motor 3 and controller and charge to battery system, utilizes the energy of electromotor 1 efficiently.It is preferred that technical scheme may is that the center of described electromotor 1, described first clutch 2, described second clutch 4, described motor 3, described variator 5 and described power transmission shaft 6 is respectively positioned on same axis.So, it is coaxially disposed so that structural system is compact, makes full use of space longitudinal before and after car load, decrease the demand to front deck space.
Above-mentioned only a kind of specific embodiment in the present invention is illustrated, but can not as protection scope of the present invention, every equivalence change done according to the design spirit in the present invention or modify, all it is deemed to fall protection scope of the present invention.
