Description
Technical field
What the present invention relates to is a kind of novel vehicle weak moderate hybrid power synthetic system, use a combination of high speed flywheel (not being the hyper-speed flywheel of new-energy automobile), planet row and motor, realize starting and quicken power-assisted, reclaim braking energy and the storage battery additional charge, be applicable to that various automobiles, trac., motor bike, beach buggy, hybrid vehicle and elec. vehicle do that braking energy reclaims and second traction, be particularly suitable for urban public traffic vehicles and auto use.
Background technology
Flywheel mainly is hyper-speed flywheel and motor direct connection as the closed-center system of new-energy automobile now, and its manufacturing cost and difficulty are all bigger; Current Recovering Waste Energy of Braking in Automobiles mainly adopts motor to be converted to the electrical generator operating mode, and braking energy is converted to power storage in storage battery, and this kind scheme is confined to the size of power of motor own and battery charge electric current for the absorption of braking energy; The scheme that has occurred storage battery and super capacitor composite absorption electrical generator energy output after this again, the reason such as big and cost owing to the power of motor own does not also reach the stage of market application; As for using hydraulic efficiency pressure system to absorb automobile brake energy, the volume of system own is bigger, and cost is higher; For pure electric vehicle, because Motor torque is restricted, its starting performance is not as internal-combustion engines vehicle.Also do not use at present the device or the system of internal combustion engine drive Recovering Waste Energy of Braking in Automobiles at market, can be effective, characteristics such as it is low to have cost simultaneously, and volume is little do not have effectively to improve the start to walk appropriate device of slow shortcoming of elec. vehicle simultaneously at present yet.
Summary of the invention
The present invention seeks to provides a kind of novel vehicle weak moderate hybrid power synthetic system at above-mentioned weak point, when being used for pure electric automobile, can significantly improve its starting performance; When absorbing braking energy, by the control of drg, motor and flywheel absorb braking energy simultaneously, change braking energy the kinetic energy of power storage in storage battery and flywheel into; When vehicle start, flywheel discharges its momentum, and bigger moment of torsion is provided at short notice, makes vehicle start more steady rapidly; Behind vehicle parking, system can be converted to the kinetic energy that the electrical generator operating mode reclaims flywheel by motor; Concrete structure partly is made up of planet row, motor and flywheel.
For achieving the above object, the present invention adopts following technical measures:
A kind of novel vehicle weak moderate hybrid power synthetic system, kinetic energy when absorbing car brakeing, be converted into electric energy and be stored in the kinetic energy of storage battery and flywheel, flywheel discharges kinetic energy when vehicle start, reach the power-assisted purpose of starting, it is characterized in that planet rows of planetary frame is connected with wheel, the external drg of planet row's internally toothed annulus, planet row sun wheel connects flywheel and motor by a power-transfer clutch, when car brakeing, motor changes the electrical generator operating mode into, and then a kinetic energy part of coming from the pinion carrier transmission is absorbed by motor, a part changes the kinetic energy of flywheel into, and this part energy is stored and is carried out utilization.
This method specifically may further comprise the steps:
1) when vehicle ', planet row's internally toothed annulus and planet row sun wheel are freely rotated, disengaging of clutch, and flywheel and rotor are in free state; When car brakeing, the drg braking of planet row internally toothed annulus periphery, planet row sun wheel connects clutch engagement, and motor changes the electrical generator operating mode into, motor absorption fraction braking energy changes electric energy into and is stored in storage battery, and flywheel absorbs the kinetic energy that most of braking energy changes flywheel into; Be lower than certain value when braking procedure proceeds to the pinion carrier rotating speed, disengaging of clutch, flywheel reach certain rotating speed and motor rotates together.
2) vehicle is started to walk again within a short period of time after detecting vehicle parking, and then planet row internally toothed annulus is connected with a drg, this drg braking planet row internally toothed annulus, and clutch engagement discharges flywheel energy, reaches the power-assisted purpose of vehicle start; If flywheel does not have kinetic energy when vehicle start, the motor-driven flywheel is to certain rotating speed, and then braking planet row's internally toothed annulus and engaging clutch, reaches the power-assisted purpose of starting, and this function is significantly improved the starting performance of pure electric automobile.
3) shut down above the regular hour when detecting the vehicle parking rear engine, then motor changes the electrical generator operating mode into, absorbs flywheel energy, changes power storage in storage battery, and this moment, charging current can be by control, the charge characteristic of suitable automobile battery.
A kind of novel vehicle weak moderate hybrid power synthetic system takes following scheme to realize: a kind of novel vehicle weak moderate hybrid power synthetic system structure has starting-up to speed power-assisted and brake power recovering device, it is characterized in that structure has planet row, flywheel, motor section and is grouped into; Planet rows of planetary frame (1) is connected with wheel or parallel connection and vehicle transmission system, the A end of planet row's sun wheel (2) coaxial connection power-transfer clutchs (8), described power-transfer clutch (8) secondary part and the coaxial connection of flywheel (6), described flywheel (6) and the coaxial connection of motor (9), satellite gear (3) is installed on the described planet rows of planetary frame (1), with described planet row's sun wheel (2) and planet row's internally toothed annulus (4) engagement, described planet row's internally toothed annulus (4) peripheral (or side) is equipped with brake collar (or magnet stopper) (5), can connection gear (or sprocket wheel) (7) at described planet rows of planetary frame (1), described gear (7) can be used for being connected with wheel or transmission system.
The present invention's " a kind of novel vehicle weak moderate hybrid power synthetic system " is to utilize present mature planetary wheel manufacturing technology, motor, high speed flywheel and control technology, through well-designed back the synthetic system of a kind of novel vehicle weak moderate hybrid power is proposed, be used for vehicle and can effectively absorb its braking energy, the dynamic property that has vehicle when improving vehicle start and acceleration simultaneously, improve its whole efficiency, reach energy-saving and emission-reduction, prolong driving engine and transmission system life-span.Its principle of work is as follows: when vehicle ', planet row's internally toothed annulus and planet row sun wheel are freely rotated, disengaging of clutch, flywheel and rotor are in free state, when car brakeing, act on the drg braking of internally toothed annulus, clutch engagement, motor changes the electrical generator operating mode into, motor absorption fraction braking energy changes electric energy into and is stored in storage battery, and flywheel absorbs the kinetic energy that most of braking energy changes flywheel into, is lower than certain value at vehicle speed, disengaging of clutch, this moment, flywheel was because its inertia drives the motor rotation; Within a short period of time, vehicle was started to walk again after detecting vehicle parking, and then planet row internally toothed annulus is connected with a drg, this drg braking internally toothed annulus, and clutch engagement discharges flywheel energy, reaches the power-assisted purpose of vehicle start; Shut down above the regular hour when detecting the vehicle parking rear engine, then electrical generator work absorbs flywheel energy, changes power storage in storage battery.
