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.
