Abstract

An electrical family car, including: an electrically driven motor; and wheels with a radius larger than 90 cm. In such cars one of the dominating energy losses is directly related to the car axial to wheel friction. The car efficiency could therefore be increased by increasing the car wheel diameter which could yield a larger traveling distance for the same axial to wheel friction related energy loss.

Claims

1. An electrical passenger car, comprising:

an electrically driven motor; and

wheels,

wherein said wheels comprise a first wheel, a second wheel, a third wheel, and a fourth wheel, and

wherein said first wheel and said second wheel have a radius 20 percent larger than said third wheel and said fourth wheel,

wherein said third wheel and said fourth wheel have a radius greater than 90 cm, and

wherein said passenger car is designed to travel for a greater distance for the same axial to wheel friction energy loss than a passenger car having wheels of a smaller radius.

2. The electrical passenger car according to claim 1, further comprising:

electrical steering,

wherein said wheels comprise a first wheel and a second wheel, and

wherein said electrical steering comprises independently controlling a first speed of said first wheel and independently controlling a second speed of said second wheel.

3. The electrical passenger car according to claim 1,

wherein at least one of said wheels comprises a wave shape profile,

wherein said at least one of said wheels comprises at least a portion of wheel contact with a road being solely diagonal with respect to the driving direction of the car.

4. The electrical passenger car according to claim 1,

wherein said car comprises at least one non-electric motor.

5. The electrical passenger car according to claim 1,

wherein said first wheel and said second wheel have a radius larger than 90 cm.

6. The electrical passenger car according to claim 1,

wherein at least one of said wheels has a radius that is at least three times larger than its width.

19. The electrical passenger car according to claim 1,

wherein said passenger car is designed to operate efficiently on a paved road.

7. An electrical passenger car, comprising:

an electrically driven motor;

wheels; and

electrical steering,

wherein said wheels comprise a first wheel and a second wheel,

wherein said electrical steering comprises independently controlling a first speed of said first wheel and independently controlling a second speed of said second wheel,

wherein said first wheel has a radius greater than 90 cm, and

wherein said passenger car is designed to travel for a greater distance for the same axial to wheel friction energy loss than a passenger car having wheels of a smaller radius.

8. The electrical passenger car according to claim 7,

wherein at least one of said wheels has a radius larger than 90 cm.

9. The electrical passenger car according to claim 7,

wherein at least one of said wheels has a wave shape profile,

wherein said at least one of said wheels comprises at least a portion of wheel contact with a road being solely diagonal with respect to the driving direction of the car.

10. The electrical passenger car according to claim 7,

wherein said car comprises at least one non-electric motor.

11. The electrical passenger car according to claim 7,

wherein said wheels comprise a first wheel, a second wheel, a third wheel, and a fourth wheel, and

wherein said first wheel and said second wheel have a radius 20 percent larger than said third wheel and said fourth wheel.

12. The electrical passenger car according to claim 7,

wherein at least one of said wheels has a radius that is at least three times larger than its width.

20. The electrical passenger car according to claim 7,

wherein said passenger car is designed to operate efficiently on a paved road.

13. An electrical passenger car, comprising:

an electrically driven motor; and

wheels,

wherein at least one of said wheels has a wave shape profile,

wherein said at least one of said wheels comprises at least a portion of wheel contact with a road being solely diagonal with respect to the driving direction of the car, and

wherein at least one of said wheels has a radius that is at least three times larger than its width.

14. The electrical passenger car according to claim 13,

wherein at least one of said wheels has a radius larger than 90 cm.

15. The electrical passenger car according to claim 13, further comprising:

electrical steering,

wherein said wheels comprise a first wheel and a second wheel, and

wherein said electrical steering comprises independently controlling a first speed of said first wheel and independently controlling a second speed of said second wheel.

16. The electrical passenger car according to claim 13,

wherein said car comprises at least one non-electric motor.

17. The electrical passenger car according to claim 13,

wherein said wheels comprise a first wheel, a second wheel, a third wheel, and a fourth wheel, and

wherein said first wheel and said second wheel have a radius 20 percent larger than said third wheel and said fourth wheel.

18. The electrical passenger car according to claim 13,

wherein said wheels comprise a first wheel, a second wheel, a third wheel, and a fourth wheel, and

wherein said first wheel and said second wheel have a radius 20 percent larger than said third wheel and said fourth wheel, and

wherein said third wheel and said fourth wheel have a radius larger than 90 cm.
