2). as the distortion of the first mode of operation, the flywheel 1 of described driving engine 10 is inputted as power, the hollow rotor shaft 5 of described the first motor 30 is exported as power, but clutch assembly is in released state, therefore the main shaft 6 that links to each other with clutch driven disc assembly 2 is neither done as the power input, does not also export as power.
At this moment, driving engine 10 runnings, thereby the flywheel of driving engine 10 1 drives rotor shaft 5 rotations that clutch cover and plate assembly 3 drives the first motor 30, so that the first motor 30 is with generator mode work, be electric energy and export closed-center system to thereby will transmit the kinetic transformation that comes by driving engine 10, so that it is charged.
And this moment, the second motor 40 can namely be powered to it by closed-center system with electric motor mode work, take the electric energy conversion that will be carried by closed-center system as kinetic energy and export speed reduction gearing 60 to, and finally is passed to wheel, with the driving Vehicle Driving Cycle.
3). the flywheel 1 of described driving engine 10 is as the power input, and the hollow rotor shaft 5 of described the first motor 30 is as the power input, and the main shaft 6 of described speed reduction gearing 60 is exported as power.
At this moment, driving engine 10 running, clutch assembly is in engagement state, is passed to speed reduction gearing 60 with the kinetic energy with driving engine 10 self by clutch driven disc assembly 2 and main shaft 6.Simultaneously, closed-center system is to 30 power supplies of the first motor, the first motor 30 is with electric motor mode work, take the electric energy conversion that will be carried by closed-center system as kinetic energy, thereby the rotor shaft of the first motor 30 5 drives clutch cover and plate assembly 3 and rotates, and is delivered to speed reduction gearing 60 by the clutch driven disc assembly 2 that engages.
At this moment, the second motor 40 can namely be powered to it by closed-center system with electric motor mode work, take the electric energy conversion that will be carried by closed-center system as kinetic energy and export speed reduction gearing 60 to.In the case, the kinetic energy that is delivered to speed reduction gearing 60 all is passed to wheel, to drive Vehicle Driving Cycle.
Perhaps, the second motor 40 also can be with generator mode work, be about to driving engine 10 and be passed to the second motor 40 by a part of kinetic energy that clutch driven disc assembly 2 exports speed reduction gearing 60 to, take by the second motor 40 with this part kinetic transformation as electric energy and be delivered to closed-center system, so that it is charged.In the case, the remaining kinetic energy that exports speed reduction gearing 60 to is passed to wheel, to drive Vehicle Driving Cycle.
4). as the distortion of the third mode of operation, the hollow rotor shaft 5 of described the first motor 30 is inputted as power, the main shaft 6 of described speed reduction gearing 60 is exported as power, but driving engine 10 does not start, therefore the flywheel 1 of described driving engine 10 neither as the power input, is not exported as power yet.
At this moment, driving engine 10 does not start, and clutch assembly is in engagement state.Closed-center system is to 30 power supplies of the first motor, the first motor 30 is with electric motor mode work, take the electric energy conversion that will be carried by closed-center system as kinetic energy, rotate thereby the rotor shaft of the first motor 30 5 drives clutch cover and plate assemblys 3, and be delivered to speed reduction gearing 60 by the clutch driven disc assembly 2 that engages.
At this moment, the second motor 40 can namely be powered to it by closed-center system with electric motor mode work, take the electric energy conversion that will be carried by closed-center system as kinetic energy and export speed reduction gearing 60 to.In the case, the kinetic energy that is delivered to speed reduction gearing 60 all is passed to wheel, to drive Vehicle Driving Cycle.
Although below only the flywheel 1 of described driving engine 10 is inputted as power, described main shaft 6 is exported as power, and the hollow rotor shaft 5 of described the first motor 30 or input as power, perhaps the situation as power output is described, but those skilled in the art should be understood that, the flywheel 1 of described driving engine 10 also can be used as power output, and described main shaft 6 also can be used as the power input, for example comes under the transition condition of start the engine 10 by the second motor 40 when clutch assembly is in engagement state.
In addition, hybrid electric drive system provided by the invention also has the energy feedback pattern, and mainly be to utilize the second motor 40 to realize energy feedback, specifically, when car retardation, the second motor 40 will by by the moment of torsion of wheel feedback with generator mode work, thereby be the closed-center system charging.
