The revolving speed of shaft 3 is consistent.Meanwhile the solenoid valve on controller control gas outlet 5 is opened, the solenoid valve on air inlet 4 closes
It closes, the air in casing 1 is extracted in the turbine flabellum rotation on turbofan II8 out；At this point, 1 air pressure inside of casing gradually decreases,
Until near vacuum state.When baroceptor detects in chassis chamber that pressure is extremely low until when near vacuum, controller makes to fly
It takes turns energy storage device 11 to start, flywheel high speed rotation, fly so that the kinetic energy of output shaft 3 be made to enter along gear V67 and gear VI68
The flywheel for taking turns the rotation of 11 high speed of energy storage device carries out energy stores.The state can be used for the abundant state of output kinetic energy, such as electronic
Automobile downhill period etc..
Power-assisted state: controller controls the solenoid valve on gas outlet 5 and closes, and the power of first stage is proposed by high speed flywheel
Output, energy accumulation device for fly wheel 11 provide power output, and the high speed flywheel of energy accumulation device for fly wheel 11 passes through gear V67 and gear VI68
Auxiliary rotary power is provided for output shaft 3；After the power output of energy accumulation device for fly wheel 11, poke rod 9 is stirred to the right, is passed
The drive socket I611 and drive socket II612 of dynamic device 6 move right, and drive socket I611 is separated with turbofan II8 phase,
Rubber pad I613 on drive socket II612 is in contact with the rubber pad II614 on turbofan I7；Meanwhile controller is opened
Solenoid valve on air inlet 4, air enter to form air-flow from air inlet, and air-flow pushes 16 turns of turbine flabellum on turbofan I7
Dynamic, the rotational power of turbofan I7 is sent to output shaft 3 by drive socket II612, and it is dynamic to provide auxiliary for the rotation of output shaft 3
Power.According to the actual situation, auxiliary power output can also be carried out simultaneously.The state can be used for output kinetic energy shortcoming state, such as electronic
Automobile up slope period, electric motor starting state increase staring torque etc..
Meanwhile the present invention can also be inflated energy storage: the solenoid valve that controller controls gas outlet is closed, the electricity of air inlet
Magnet valve is opened, and output shaft 3 drives the turbine flabellum rotation of the turbofan I7 of air inlet by transmission device 6, to high-intensitive machine
Gas is persistently injected in 1 inside of shell, and 1 internal pressure of casing increases.When pressure reaches critical value, the high speed of energy accumulation device for fly wheel 11 flies
Energy storage is taken turns to start to work.When power-assisted is exhausted, the solenoid valve that controller controls gas outlet is opened, and the solenoid valve of air inlet closes
It closes.Compressed air stream pushes the turbine flabellum rotation of the turbofan II8 of gas outlet, to drive output shaft 3 by transmission device 6
Rotation.It is corresponding with the pumping workflow of two kinds of energy storage modes of energy storage to inflate energy storage.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
