Electromotive drives
First Claim
1. A vehicle comprising:
- an input power source; and
an electromotive device comprising;
a plurality of power adjusters arranged angularly about an axis and in contact with an idler positioned between the plurality of power adjusters and coaxial with the axis, each power adjuster rotatable about a respective tiltable axle,a first disc in contact with the plurality of power adjusters, the first disc configured to receive an input torque from the input power source and to transfer the input torque to the plurality of power adjusters,a second disc in contact with the plurality of power adjusters and configured to transfer an output torque to a mechanical device, the mechanical device being one of an output shaft and a rotatable hub shell, wherein the first and second discs are positioned relative to one another on opposite sides of the plurality of power adjusters,an electrical stator coupled to one of the first disc, the second disc, and the idler, andan electrical rotor coupled to another one of the first disc, the second disc, and the idler.

Abstract
A transmission having a plurality of tilting balls and opposing input and output discs provides an infinite number of speed combinations over its transmission ratio range. The transmission provides multiple powerpaths and can be combined with electrical components to provide motor/generator functionality, which reduces the overall size and complexity of the motor and transmission compared to when they are constructed separately. In one embodiment, rotatable components of a continuously variable transmission are coupled separately to an electrical rotor and to an electrical stator so that the rotor and stator rotate simultaneously in opposite directions relative to one another. In other embodiments, an electrical rotor is configured to transfer torque to or from a disc that is in contact with a plurality of speed adjusters, while an electrical stator is configured to transfer torque to a shaft that is operationally coupled to the speed adjusters via an idler.
