The concise and to the point description of the concrete working process of the utility model is: when vehicle is started to walk for the first time, flywheel 4 rotating speeds are zero, and store mechanical energy not in the flywheel 4, at this moment, electric controller DK passes through fly wheel brake 5 with flywheel 4 lockings, if electric controller DK drives first motor/generator 1 and the second motor/generator 7-5 works simultaneously, at this moment, gear ring 7-1 and sun wheel 7-4 rotate, and pinion carrier 7-3 does not rotate, and the torque T of the second motor/generator 7-5
CmPass through on the clutch end that is added to after power coupled drive assembly 7 amplifies k times, then increased the breakaway torque of car load, reduced pick-up time, the torque of wheel is during starting
Along with the increase of the speed of a motor vehicle, namely drive the rotation speed n of wheel
wIncrease by the rotation speed n of the second motor/generator 7-5
CmProportional increase simultaneously.Namely
When vehicle need slow down, fly wheel brake 5 was released by electric controller DK, simultaneously the second motor/generator 7-5 was applied a negative torque T
Cm, namely entering generating state, the second motor/generator 7-5 reduces speed now, and at this moment, pinion carrier 7-3 rotates, and drive flywheel 4 also rotates.Like this, be applied on the clutch end after the amplification of the negative torque of the second motor/generator 7-5 by power coupled drive assembly 7, can be presented as car brakeing feedback torque T
Br, make car retardation.Namely
This torque simultaneously is applied on the flywheel 4 by planetary wheel 7-2, pinion carrier 7-3 and the second motor/generator 7-5, makes flywheel 4 enter acceleration mode, i.e. flywheel 4 torques are
Flywheel 4 acceleration this moment, and second motor/generator 7-5 and the car retardation, be a kinetic energy part before the car brakeing by second motor/generator 7-5 generating and enter storage battery, a part is converted into the mechanical energy of flywheel 4 in addition, is stored in the flywheel 4.Flywheel 4, the second motor/generator 7-5 and vehicle wheel rotational speed satisfy simultaneously
Because the inertia of vehicle is bigger, and the rotor inertia of flywheel 4 and the second motor/generator 7-5 is less, makes the deceleration of the second motor/generator 7-5 faster than the deceleration of vehicle integral body, therefore, when the rotating speed of the second motor/generator 7-5 was reduced to zero, at this moment, the speed of a motor vehicle was still higher.If also need car retardation, at this moment the second motor/generator 7-5 is still applied negative torque, the second motor/generator 7-5 enters and is reciprocal acceleration mode, namely enters motoring condition.At this moment the kinetic energy of vehicle all is converted into the kinetic energy of flywheel 4, the second motor/generator 7-5 also is converted into a part of electric energy the kinetic energy of flywheel 4 simultaneously, flywheel 4 continues to accelerate, till car retardation stops, this moment, flywheel 4 still kept high rotating speed, the second motor/generator 7-5 keeps negative rotating speed, namely
At this moment, if vehicle needs to accelerate, then the second motor/generator 7-5 is applied positive torque, enter generating state, the second motor/generator 7-5 begins reverse deceleration, and this positive torque simultaneously is applied to clutch end after amplifying by power coupled drive assembly 7, for wheel accelerates to provide power; This torque simultaneously also is applied on the high speed flywheel 4 by power coupled drive assembly 7, and flywheel 4 is slowed down (torque concerns with above-mentioned moderating process).A kinetic energy part that is flywheel 4 is converted into electric energy by the second motor/generator 7-5, and a part is converted into the kinetic energy of vehicle in addition.
Continuation along with the vehicle acceleration mode, after the second motor/generator 7-5 oppositely is decelerated to zero rotating speed, then the second motor/generator 7-5 is continued to apply forward torque, the second motor/generator 7-5 begins forward to accelerate, enter motoring condition, accelerate to finish (rotation speed relation is opposite with above-mentioned moderating process) until vehicle.
More than be one complete from decelerating to the description of accelerator.
If when the mechanical energy of flywheel 4 storage was zero, electric controller DK again with flywheel 4 lockings, when vehicle is slowed down, can discharge flywheel 4 by fly wheel brake 5 again, make flywheel 4 store mechanical energy.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
