Hybrid power automobile power system
[technical field]
The present invention relates to a kind of is the hybrid power automobile power system of propulsion source with fuel oil and electric power energy, especially possesses the hybrid power automobile power system of pure motor driving ability.
[background technology]
Because the fuel oil power vehicle is to the pollution of environment and to the consumption problem of the energy, electronlmobil and hybrid vehicle have become one of motor field current hot of research and development.
The power system version of existing hybrid vehicle has series, parallel and three kinds of forms of series-parallel connection.THS combined hybrid system of the IMA parallel system of the Insight of Honda company and the Prius of Toyota Company etc. for example.Wherein, the IMA system architecture of the Insight of Honda company is simple, but motor only possesses power-aid function, does not possess the pure motor driving ability, belongs to the Weak hybrid power form.The THS combined hybrid system of the Prius of Toyota Company possesses the pure motor driving ability, but its power combination mechanism complexity, volume is big, manufacturing cost is high.
Chinese patent CN1420034 discloses a kind of double-motor hybrid vehicle power system, and it comprises combustion engine, motor, power-transfer clutch, change speed gear box, electrokinetic cell, brake system and car load autonomous cruise speed system.And have major and minor two motors, and the rotor shaft of its main motor is connected with the output shaft of change speed gear box, and be connected with the bent axle of combustion engine major and minor motor and battery of the rotor shaft of auxiliary-motor electrically connects.This double-motor hybrid vehicle power system is compared its structure with traditional technology and has been simplified some a little, and has the ability of pure motor driving.But its defective still exists: assembly is too much, and difficult arrangement, the dynamic property of vehicle, fuel economy and emission behavior also can't be satisfactory.
Therefore, this technology awaits further to improve.
[summary of the invention]
Technical matters to be solved by this invention provides a kind of compact conformation, can realize parallel connection, series connection, series-parallel connection and the pure electronic mode of operation of vehicle simultaneously, and improves the hybrid power automobile power system of dynamic property, fuel economy and the emission behavior of vehicle.
For solving the problems of the technologies described above:
Hybrid power automobile power system of the present invention comprises driving engine, change speed gear box, power battery pack and electric control clutch.Comprise in addition: one starts the pusher side motor, and its rotor links with the crankshaft output end of driving engine and the active member of electric control clutch simultaneously.One gear-box side motor, it links with the input shaft of change speed gear box and the driven shaft element of electric control clutch simultaneously.Above-mentioned two motors are powered by power battery pack, and are electrically connected with an electric machine controller respectively, and controlled by it.A central controller, its connection and control electric control clutch and power battery pack and said two generator controllers.
Preferred scheme has:
The described pusher side motor and gear-box side motor and electric control clutch of starting integrates, and is installed among the clutch bell of driving engine.
Positive progressive effect of the present invention is:
It is too much to have improved the hybrid power system assembly, problems such as difficult arrangement.Also reduced simultaneously the work capacity that hybrid power transmission system is changed the orthodox car arrangement structure.
Cancelled the flywheel of driving engine, compact conformation can be realized parallel connection, series connection, series-parallel connection and the pure electronic mode of operation of vehicle simultaneously, thereby improves dynamic property, fuel economy and the emission behavior of vehicle.
Double-motor and power-transfer clutch are integrated, simplified power transmission system structure, reduced the layout difficulty of power drive system.
[description of drawings]
The present invention is further detailed explanation in conjunction with example with reference to the accompanying drawings:
Fig. 1 is the structural representation of an embodiment of the present invention.
[specific embodiment]
As shown in the figure,
The electric machine controller 6 of electric machine controller 5, electric control clutch 3, gear-box side motor 4 and this gear-box side motor that hybrid power automobile power system of the present invention comprises driving engine 1, starts pusher side motor 2, this starts the pusher side motor, vehicle general controller 7, power battery pack 8 and change speed gear box 9 are formed.
Start the rotor of pusher side motor 2 to link to each other with the crankshaft output end of driving engine 1 and the active member of electric control clutch 3 simultaneously; Gear-box side motor 4 links to each other with the input shaft of change speed gear box 9 and the drive element of electric control clutch 3 simultaneously; Two motors 24 and electric control clutch 3 integrate, and are installed in the clutch bell of driving engine 1; Two motors 24 provide electric energy by power battery pack 8 simultaneously, and running under controller 56 controls separately; 7 pairs of electric machine controllers 56 of vehicle general controller, electric control clutch 3 and power battery pack 8 are carried out co-operative control.
During vehicle launch, can be by gear-box side motor 4 direct drive vehicle starts; Also can separate electric control clutch 3,,, thereby realize vehicle start by driving engine again in conjunction with power-transfer clutch by starting pusher side motor 2 fire an engine 1 at short notice; Also can use two kinds of patterns to realize vehicle start simultaneously.
In the vehicle ' process, separate electric control clutch 3, driving engine 1 drives and starts 2 generatings of pusher side motor, and gear-box side motor 4 powered vehicle are travelled, thereby realize the tandem drive of vehicle, and power battery pack 8 is as the adjustment module of electric energy.
In the vehicle ' process, in conjunction with electric control clutch 3, driving engine 1 and gear-box side motor 4 powered vehicle simultaneously travel, thereby realize the transmission in parallel of vehicle.
In the vehicle ' process, in conjunction with electric control clutch 3, a part of driving of the power of driving engine 1 started 2 generatings of pusher side motor, and power storage is in power battery pack 8, and a part and gear-box side motor 4 powered vehicle simultaneously travel, thereby realize the series-parallel connection transmission of vehicle.
When car retardation braking and descending, separate electric control clutch 3, kill engine 1, gear-box side motor 4 becomes electrical generator, realizes regenerative brake, and the energy of regenerative brake is stored in the power battery pack 8.
When car retardation braking and descending, in conjunction with electric control clutch 3, kill engine 1, start pusher side motor 2 and gear-box side motor 4 to become electrical generator, carry out regenerative brake and Jake brake simultaneously, the energy of regenerative brake is stored in the power battery pack 8.
When being used for hybrid vehicle, the present invention can realize engine drive, driving in parallel, tandem drive and pure motorized motions pattern simultaneously.
The foregoing description just embodies the preferred version of technical solution of the present invention, those skilled in the art to wherein some part some changes that may make all embodied principle of the present invention, belong within protection scope of the present invention.
