Abstract

Toy vehicles having a toy vehicle body having front and back ends, front and rear axles, each axle having first and second wheels fastened onto respective ends thereof, the wheels having elastic tires thereon, the front and rear axles being mounted to the toy vehicle body with the axles being parallel to each other, a motor within the toy vehicle body, and a source of electrical power within the toy vehicle body, the motor being disposed with an axis of its motor shaft passing through an axis of one of the axles and contacting the side of a tire on the wheel adjacent the motor shaft to drive the tire and thus both wheels on the respective axle in rotation to propel the toy vehicle, the side of the tire contacted by the motor shaft facing the second tire and wheel on the same axle.

Claims

1. A toy vehicle comprising:

a toy vehicle body having front and back ends;

four elastic tires, at least one elastic tire having a raised annular area on a side of the tire, the raised area having a diameter that is less than an outer diameter of the tire;

four wheels, each wheel having an elastic tire thereon;

front and rear axles, each axle having first and second wheels fastened onto respective ends thereof, the raised annular area on the side of the tire being arranged to face the opposite wheel;

the front and rear axles being mounted to the toy vehicle body with the axles being parallel to each other; and

a motor within the toy vehicle body, the motor including a motor shaft that contacts the raised annular area on the side of one tire to drive the tire by frictional forces on the side of the tire.

2. The toy vehicle of claim 1 wherein the axis of the motor shaft is perpendicular to the respective axle.

3. The toy vehicle of claim 2 wherein the motor is disposed with an axis of its motor shaft passing through an axis of the front axle and contacting the first side of the tire contacted by the motor shaft to drive the tire by frictional forces on the first side of the tire and thus both front wheels on the front axle in rotation to propel the toy vehicle.

4. The toy vehicle of claim 1 wherein all four tires are the same.

5. The toy vehicle of claim 4 wherein the front and rear axle assemblies are the same, each axle assembly comprising the axle, pair of wheels and tires being removable as an assembly from and re-mountable as an assembly on the toy vehicle body, whereby the raised area of the tire frictionally contacted by the motor shaft may be replaced with another of the four tires by swapping the drive axle end for end, and/or by swapping the front and rear axles.

6. The toy vehicle of claim 4 wherein the tires are removable from and re-mountable on the wheels, whereby the raised area of the tire frictionally contacted by the motor shaft may be replaced with another of the four tires.

7. The toy vehicle of claim 6 wherein the body of the toy vehicle comprises an upper body member and a lower body member that are fastened together.

8. The toy vehicle of claim 7 wherein the upper body member and the lower body member, when fastened together, retain a super capacitor as the source of electrical power within the toy vehicle body and the motor.

9. The toy vehicle of claim 8 wherein the upper body member extends over the lower body member whereby there is no joint or gap visible when viewing the toy vehicle from either side or either end of the toy vehicle.

10. The toy vehicle of claim 8 wherein an elastic member is disposed between the motor and the body.

11. The toy vehicle of claim 10 wherein the elastic member is positioned in the body to cause the upper body member to push the motor against the lower body member, whereby the lower body member determines the position and alignment of the motor relative to the side of the tire the motor shaft frictionally contacts.

12. The toy vehicle of claim 1 wherein the source of electrical power within the toy vehicle body is a super capacitor.

13. The toy vehicle of claim 12 wherein the super capacitor and the motor are wired together without a switch between the super capacitor and the motor.

14. The toy vehicle of claim 13 wherein ends of the leads of the super capacitor are bent to form contacts at a back of the toy vehicle for contact by a charger.

22. The toy vehicle of claim 2 wherein an elastic member is disposed between the motor and the body.

23. The toy vehicle of claim 22 wherein the elastic member is positioned in the body to push the motor against the lower body member, whereby the lower body member determines the position and alignment of the motor relative to the side of the tire the motor shaft frictionally contacts.

26. The toy vehicle of claim 1 wherein the front and rear axles pass through the toy vehicle body and the axle having the wheel with the driven tire is retained from further motion along its axis by the opposite wheel rubbing against the toy vehicle body.

15. A toy vehicle comprising:

a toy vehicle body having a front and a back;

four elastic tires, at least one elastic tire having a raised annular area on a side of the tire, the raised area having a diameter that is less than an outer diameter of the tire;

four wheels, each wheel having an elastic tire thereon;

front and rear axles, each axle having first and second wheels fastened onto respective ends thereof, the raised annular area on the side of the tire being arranged to face the opposite wheel;

the front and rear axles being mounted to the toy vehicle body with the axles being parallel to each other; and

a motor within the toy vehicle body, the motor including a motor shaft that contacts the raised annular area on the side of one tire to drive the tire by frictional forces on the side of the tire; and

a super capacitor within the toy vehicle body and permanently electrically connected to the motor.

16. The toy vehicle of claim 15 wherein all four tires are the same.

17. The toy vehicle of claim 16 wherein the front and rear axles, wheels and tires comprising an axle assembly are the same, the axle assemblies being removable from and re-mountable on the toy vehicle body, whereby the tire frictionally contacted by the motor shaft may be replaced with another of the four tires by swapping the drive axle end for end, and/or by swapping the front and rear axles.

18. The toy vehicle of claim 16 wherein the tires are removable from and re-mountable on the wheels, whereby the tire frictionally contacted by the motor shaft may be replaced with another of the four tires.

19. The toy vehicle of claim 18 wherein the body of the toy vehicle comprises an upper body member and a lower body member that are fastened together.

20. The toy vehicle of claim 19 wherein the upper body member and the lower body member, when fastened together, retain the super capacitor and the motor.

21. The toy vehicle of claim 20 wherein the upper body member extends over the edges of the lower body member whereby there is no joint or gap visible when viewing the toy vehicle from either side or either end of the toy vehicle.

24. The toy vehicle of claim 15 wherein ends of the leads of the super capacitor are bent to form contacts at a back of the toy vehicle for contact by a charger.

25. The toy vehicle of claim 15 wherein the front and rear axles pass through the toy vehicle body and the axle having the wheel with the driven tire is retained from further motion along its axis by the opposite wheel rubbing against the toy vehicle body.
