Abstract

A wheel, such as a traction wheel, with a momentum enhancing apparatus. The momentum enhancing apparatus may selectively enhance the wheel'"'"'s ability to maintain its angular velocity at relatively high speeds, while having a reduced effect on the angular velocity of the wheel at relatively slow speeds. The momentum enhancing apparatus may include one or more bodies that either translate radially between the hub and the rim of the wheel to change the mass moment of inertia of the wheel, or rotate with the wheel and transfer the momentum of the bodies to the wheel under increasing loads. Methods of using such apparati and vehicles equipped with such apparati are also enclosed.

Claims

1. A wheel adapted to provide locomotive traction while in contact with a surface, said wheel including a hollow interior including a series of hollow segments, said hollow segments are each adapted for storing and transferring a fluid to other said segments, said storing and transferring said fluid modifies a mass moment of inertia of said wheel when said wheel is accelerating or decelerating while rotating.

2. The wheel of claim 1, wherein said storing and transferring of said fluid automatically modifies said mass moment of inertia of said wheel as a function of the angular velocity of said wheel.

3. The wheel of claim 1, wherein said storing and transferring of said fluid selectively modifies the mass moment of inertia of said wheel.

4. The wheel of claim 1, wherein said storing and transferring of said fluid tends to maintain the mass moment of inertia when said wheel is rotationally decelerating.

5. The wheel of claim 1 wherein said storing and transferring of said fluid is adapted to modify the magnitude of the wheel'"'"'s mass moment of inertia by up to at least about seven percent.

6. The wheel of claim 1, wherein said storing and transferring of said fluid is adapted to modify the magnitude of the wheel'"'"'s moment of inertia by up to at least about forty percent.

7. The wheel of claim 1 wherein said storing and transferring of said fluid is adapted to modify the magnitude of the wheel'"'"'s moment of inertia by up to at least about twenty-five percent.

8. A traction wheel having a variable mass moment of inertia, the traction wheel including:

a traction wheel including solid components and a fluid component;

said solid components including a circular shaped body having a hollow interior including a series of hollow segments adapted for storing and transferring a fluid component; and

wherein said hollow segments providing a means for altering an angular velocity of said circular shaped body of said wheel while said wheel is rotating.

9. The traction wheel of claim 8, wherein said altering means is capable of altering said angular velocity of said body relative to an alternative angular velocity of said body when said body is otherwise absent of said fluid component.

10. The traction wheel of claim 8, wherein said body rotates about an axis of rotation, and wherein said altering means includes a tube that is substantially concentric about said axis and that encloses said fluid component.

11. The traction wheel of claim 10, wherein said tube is partially filled with said fluid.

12. The traction wheel of claim 8, wherein said body rotates about an axis of rotation, and includes a floating ring disposed substantially concentric with said axis, and wherein said altering means includes a support ring disposed substantially concentric with said axis.

13. The traction wheel of claim 12, wherein said altering means further includes means for inducing said floating ring to rotate concurrently with said support rings.
