Abstract

The invention relates to a double-rotor direct current brushless permanent magnet electromotor serial type hybrid automobile which utilizes an Audi 100 type automobile to refit and test an electric automobile. A double-rotor direct current brushless permanent magnet electromotor is connected in series between the output end of a crankshaft of a gasoline engine and an automatic transmission gearbox; an inner layer of rotor and a slip ring of a winding of the electromotor rotate along with the crankshaft of the gasoline engine; an outer layer of hollow NdFeB permanent magnet rotor is connected with an input shaft of the automatic transmission gearbox to form an electromagnetic clutch to replace a hydraulic torque converter; and the inner layer of rotor becomes a inner stator when the gasoline engine is not rotated (pure power-driven mode) and also assists the stator for electric drive and energy reclaiming in braking and slipping. The hybrid automobile is characterized in that: 1, the electromotor adopts an outer layer of hollow rotor structure of the NdFeB permanent magnet, the inner layer of rotor is cast by ironless aluminum belt coils and epoxy resin, and in order to save the space under the automobile, the stator adopts a semicircular structure; 2, the automobile is added with a direct current brushless permanent magnet electromotor controller linked with an accelerator pedal and a high-frequency switch rectifying power for charging; 3, the automobile is added with a braking energy reclaiming device linked with the accelerator pedal.

Description

Double-rotor direct current brushless permanent magnet electromotor serial type hybrid automobile

I utilized own Audi 100 Car from 1996, repacking, experiment electronlmobil, under the prerequisite not changing complete vehicle structure, successively attempted multiple spark ignition engine electrical motor array configuration:

1, DC machine is serially connected between crankshaft for gasoline engine mouth (adding free-wheel clutch) and the turbine transformer of automatic transmission, but limited space, motor does not quite, impracticable.

2, DC machine be serially connected between crankshaft for gasoline engine mouth and automatic transmission, motor stator adds slip ring and connects gasoline engine crank, and motor rotor connects automatic transmission input shaft, replaces turbine transformer with electrical motor.

3, between crankshaft for gasoline engine mouth (adding free-wheel clutch) and the turbine transformer of automatic transmission, install gear case additional and fill two DC machine in driving engine both sides, its complex structure, former car is changed large.

4, former car f-w-d structure is constant, installs Zhi stream additional Wu Shua Nd iron boron permanent magnet motor, to realize trailing wheel Direct driver in two rear wheel hubs.

5, in forward and backward four-wheel wheel hub, brush DC Nd-Fe-B permanent magnetic electrical motor is installed additional, to realize the full-time Direct driver of four-wheel.

One, through the experiment of various ways, selecting is serially connected between crankshaft for gasoline engine mouth and automatic transmission by DC brushless motor, motor windings internal layer rotor adds slip ring connection gasoline engine crank and rotates with spark ignition engine, electrical motor outer hollow rotor connects automatic transmission input shaft, composition magnetic clutch, be used for replacing turbine transformer, namely avoid the mechanical wear of turbine transformer, turn increase internal layer rotor auxiliary stator for motorized motions and brake, slide time energy regenerating.Stator, for taking space under car less, adopts semi-circular structure.

Keep former car type of drive constant, use Xiali three-cylinder engine, reach instead, its space of shifting out, place electrical motor, add:

1, the direct current brushless permanent magnet electromotor controller linked with Das Gaspedal.

2, the brake energy regenerative apparatus that the master cock linked with brake pedal controls.

3, the storage battery arranged in driving engine both sides, luggage boot.

4, the direct current brushless permanent magnet electromotor controller in luggage boot is placed on.

5, the high-frequency switch rectifying power supply of the charging in luggage boot is placed on.

Two, electrical motor is the critical component of electronlmobil, through for many years test, analysis and comparison, independently develop brush DC Shuan Zhuan Nd iron boron permanent magnet motor.

1, the hollow outer rotor of the Nd-Fe-B permanent magnet of electrical motor, is arranged on the input shaft of automatic transmission.

2, internal layer rotor is arranged on the crankshaft output end of gasoline engine generator, adds poured with epoxy resin form by aircored aluminium strip coil.The copper ring of three mutually insulateds is inlayed in its periphery, coordinates the brush holder and carbon brush that are fixed on shell, is guided to by rotor winding on controller, forms the internal layer rotor with spark ignition engine coaxial rotating.

3, cannot raise because engine crankshaft belongs to an axis to transmission input shaft, electrical motor external diameter is limited, so stator is made semicircle, makes at the bottom of car constant apart from floor level.

Three, direct current brushless permanent magnet electromotor controller

1, with brushless motor special IC MC33035 and special drive integrated circult IR2113, and high-power IGBT module composition.

2, consider vehicle-mounted changeable harsh environment, without fan cooling, but use large area aluminium radiator.

Four, high-frequency switch rectifying power supply.

1, be used for as battery charge, adopt and be now widely used ripe high-frequency switching rectifier, just transform as the high-frequency switch rectifying power supply that input voltage range is wider.

2, consider vehicle-mounted harsh environment, without fan cooling, but use large area aluminium radiator.

Five, brake energy regenerative apparatus.

Being used for conversion brake, dump energy when sliding is storage battery additional charge, also adopts and is now widely used ripe high-frequency switching rectifier, just transform as input voltage range wider, the high-frequency switch rectifying power supply of output voltage, current adjustment.

Six, storage battery.

1, experiment is lead-acid storage battery.

2, next step will adopt lithium ion battery, with expendable weight, increase capacity.

3, along with the maturation of super large bulk capacitance technology, using its device as storage of electrical energy of employing.

Seven, vehicle performance:

1, when pure spark ignition engine drives, F-Zero 100Km, travels 500Km continuously.Add energy consumption dynamic brake, improve deceleration and stopping performance, also for storage battery supplements electric power.

2, pure electronic time: F-Zero 100Km/h, travels 200Km continuously.

3, during hybrid power: F-Zero 180Km/h, travels 1100Km continuously, fuel consumption of 100km 5.2 liters.Can fuel-economizing 40%.

Eight, the overall evaluation.

1, Zhi stream is novel in design Wu the spinner motor of the hollow outer rotor of Shua Nd iron boron permanent magnetism, coiling internal layer rotor, compact conformation, and power density is high, and horsepower output is large, measures, reach 60KW with arcing time factor 30%, is enough to the vehicle driving Audi-100 such.
