Abstract: A constant velocity joint having driving and driven pivot arm segments coupled together with a pivotal bearing element provides high power density transmission through a large dynamic angle. The constant velocity joint may be configured for axial movement, such as a plunge capability, or may be a fixed center joint.

Abstract: A vehicle adapted to move along a supporting surface comprising a frame, a wheel having a centrally located hub mounted on the frame for rotational movement about a first rotational axis relative to the frame, and an inner rotatable member at least partially within the hub. The inner rotatable member is mounted for rotational movement about a second rotational axis. The inner rotatable member and the hub are movable relative to each other along a path having a radial component to permit adjustment in the relative radial position of the first and second rotational axes. The hub and the inner rotatable member are drivingly interconnected by a mechanism which includes a one-way clutch. The operator of the vehicle can adjust the relative radial position of the rotational axes to thereby adjust the drive ratio between the hub and the inner rotatable member.

Abstract: A variable speed transmission comprising outer and inner rotatable members mounted for rotation about first and second rotational axes, respectively, at least first and second one-way clutches mounted on the inner rotatable member, and first and second drive elements attached to the first and second clutches, respectively, and to the outer member so that rotation of one of the rotatable members about its rotational axis causes the drive elements to rotate the other of the rotatable members about its rotational axis. The radial spacing between the rotational axes can be adjusted to vary the drive ratio.
