Abstract

The invention is to a wind charging system for an automobile which includes a wind driven turbine blade that is attached to a plurality of alternators by a gearing system. The gearing system includes a large gear driving a plurality of small gears, each attached to an alternator. The system is mounted in a single frame that mount in the engine compartment of a standard automobile.

Claims

a single mounting frame;

a wind driven rotation device mounted on a shaft in said frame;

a plurality of automotive alternators mounted on said frame;

a first gear attached to the shaft on a first side of said wind driven rotation device;

a second gear attached to the shaft on a second side of said wind driven rotation device;

a first plurality of small gears, one each attached to an alternator and in mesh with said first gear; and

a second plurality of small gears, one each attached to an alternator and in mesh with said second gear;

whereby said wind rotation device turns said alternators through said first and second gears and said small gears to supply charging power to said plurality of batteries.

2. The charging system according to claim 1, wherein said wind driven device is a wind turbine.

3. The charging system according to claim 1, wherein said wind driven rotation device is mounted on said shaft between two sides of said mounting frame, and a plurality of said alternators are mounted on each of said two sides of said mounting frame.

4. The charging system according to claim 1, wherein said first and second gears and said plurality of small gears have a ratio of rotation, one to the other, such that the alternators are turned at a fast speed during slow speed of said wind driven rotation device.

5. The charging system according to claim 1, wherein said charging system is mounted in a standard automobile tilted at an angle to the horizontal plane to permit air flow directly against the wind driven rotation device.

6. The charging system according to claim 1, wherein said first and second gears each turns four smaller gears attached to four alternators.

7. The charging system according to claim 1, wherein said wind driven device is a single shaft windmill type blade, attached to a large gear directly driving four alternators through four small gears.

8. A wind charging system mounted in a standard automobile in the engine compartment for charging a plurality of batteries of an electrical powered vehicle at slow speeds, extending the driving range of the electrical powered vehicle, comprising:

a single mounting frame;

a wind turbine rotatably mounted on a shaft in said single frame;

a plurality of automotive alternators mounted on said single frame;

a first gear attached to said shaft on a first side of and rotated by said wind turbine;

a second gear attached to said shaft on a second side of and rotated by said wind turbine;

a first plurality of small gears, one each attached to an alternator and in mesh with said first gear; and

a second plurality of small gears, one each attached to an alternator in mesh with said second fear;

whereby said wind turbine turns said alternators through said first and second gears and said small gears to supply charging power to said plurality of batteries.

9. The charging system according to claim 8, wherein said wind turbine is mounted between two side frames, and a plurality of said alternators are mounted on each of said two frames.

10. The charging system according to claim 8, wherein said first and second gears and said plurality of small gears have a ratio of rotation, one to the other, such that the alternators are turned at a fast speed during slow speed of said turbine.

11. The charging system according to claim 8, wherein said charging system is mounted in a standard automobile, tilted at an angle to the horizontal plane to permit airflow directly against the wind driven rotation device, and through an air scoop at the bottom of the charging system.

12. The charging system according to claim 8, wherein said first and second gears each turns four smaller gears attached to four alternators.

13. The charging system according to claim 8, wherein said wind turbine is a single shaft windmill type blade, attached to a flywheel and a large gear driving four alternators.

14. The charging system according to claim 13, including a magneto used in conjunction with said flywheel to provide electrical current to a tachometer for providing a visual indication of the RPM performance of the wind charging system.

15. The charging system according to claim 8, including a flywheel mounted adjacent and extending over each of said large gears to provide rotational momentum.

16. A wind charging system mounted in a standard automobile in the engine compartment for charging a plurality of batteries of an electrical powered vehicle at slow speeds, extending the driving range of the electrical powered vehicle, comprising:
