Beneficial effect：
Main innovation point of the present invention is as follows：
1. one of present invention innovation：Rotor simplifies when transmission flywheel, system.
The power transmission shaft of heat power machine, generator, motor and oil pump is directly connected in the present invention, when individually using fuel
Drive oil pump when, heat power machine must first drive generator and motor, then drive oil pump, though now motor do not produce it is dynamic
Power, generator also do not generate electricity, and rotor passively dallies, but serve as between heat power machine and oil pump with buffering, stable used
Property flywheel.
System relative to other using engine and motor parallel, separates motor when by engine driving oil pump,
Although the friction of motor idle running, complicated, poor practicability can be reduced.And the layout structure of mechanical series is used to realize heat
The straight displacement of reservoir oil pump of engine, transmission efficiency, is not only convenient for motor and oil pump is operated alone, and also allows for heat power machine Independent Power Generation, makes
Whole device is simple and reliable for structure, while grafting can be facilitated existing and very ripe fuel generator and oil pump technology, makes this
Invention has good practicality.
The two of innovation of the invention：Generator, motor are transformed into antigravity bearing, system high efficiency.
When motor only makees power transmission shaft and inertial flywheel, because rotor weight is heavier, certain friction energy loss can be produced, and
Due to using the structure of antigravity Exciting Windings for Transverse Differential Protection in motor, it will not only increase frictional force, can also reduce whole system on the contrary
Frictional resistance.By increasing extraction wire in generator or motor stator, one group is isolated in stator winding top
Or multigroup winding, as antigravity Exciting Windings for Transverse Differential Protection, and to its independent energization, using stator core and rotor core, form one
The electromagnet structure that can up attract rotor, by control electric current, electromagnetic attraction size is set to allow generator or motor
The horizontal support bearing of power transmission shaft or together with the pressure straight down suffered by the horizontal support bearing of engine and oil pump drive spindle
Reduce or be zero.Because engine, generator, motor and oil pump are horizontal installation, and the moving component in four,

It is only relevant with the radial pressure straight down that bearing is born to wipe power, and it is unrelated with the level of torque of oil pump load and power transmission shaft, one
The denier pressure reduces even zero, will substantially reduce frictional resistance when bearing rotates, while can reduce vibrations and noise.
This plain bearing adds rotor and the frame mode of antigravity Exciting Windings for Transverse Differential Protection, energy similar with magnetic bearing structure
The gravity for bearing bearing radial direction reduces even to zero, and equivalent under weightlessness, acquisition is similar to magnetic suspension shaft
The effect held.Due to using engine, generator, motor and the direct cascaded structure of oil pump, now whole generator and electronic
Machine is not only into connection engine and the power transmission shaft and flywheel of oil pump, and when coupling device is using being rigidly connected, also turning into prop up
The antigravity bearing of engine and oil pump itself power transmission shaft is supportted, thus the entirety of this generation antigravity effect is named as bob-weight
Power bearing.
Generator or motor become bearing, and antigravity Exciting Windings for Transverse Differential Protection structure seems very complicated, but in fact and need not send out
Additionally increasing part on motor and motor body again, bearing, rotor and stator are all that generator and motor itself are existing,
Simply by optimization stator winding, increase extraction wire, produce unique antigravity Exciting Windings for Transverse Differential Protection structure, make existing generator and
Motor turns into a huge antigravity bearing, and a more high-quality zero-g inertial flywheel, and cost only has magnetcisuspension
The some thousandths of that floating axle is held, this is exactly the ingenious part of the present invention.
When generator or motor need to recover to generate electricity with driving function, pass through the switching list in antigravity control module
Member, the lead of antigravity Exciting Windings for Transverse Differential Protection is switched over, antigravity Exciting Windings for Transverse Differential Protection is returned into generator or motor immediately
In stator winding.
Further, the present invention also has a variety of operating conditions, and therefore, flexibility is extremely strong.
In summary, double dynamical oil pump of the invention and double dynamical oil pump control method are easy to implement, simple in construction.Operation
Flexibly, energy utilization rate is high, is adapted to popularization and application.
