Patent ID: 7166052

Claim:
A hybrid vehicle, comprising: a first source of rotational energy; a second source of rotational energy; and a transmission adapted to accept rotational energy from both the first and second sources comprising; a longitudinal axis; a plurality of balls distributed radially about the longitudinal axis, each ball having a tiltable axis about which it rotates; a rotatable input disc positioned adjacent to the balls and in contact with each of the balls; a rotatable output disc positioned adjacent to the balls opposite the input disc and in contact with each of the balls; a rotatable idler coaxial about the longitudinal axis and positioned radially inward of and in contact with each of the balls; and a rotatable cage adapted to maintain the axial and radial position of each of the balls; wherein the first source supplies rotational energy to the cage and the second energy source supplies rotational energy to the input disc.
