摘要： In a vehicle installed with in-wheel motors, a continuously variable transmission provided in a power transmission path between the in-wheel motor and a wheel has an input member that rotates as a unit with a rotor, an output member that rotates as a unit with a drive shaft, planetary balls that transmit torque between the input member and the output member, a support shaft that rotatably supports each of the planetary balls, and a carrier that can tilt the planetary balls by changing the radial positions of opposite end portions of the support shaft. The continuously variable transmission can change the speed ratio by changing the tilting angle of the planetary balls by means of the carrier.

摘要： Devices and methods are provided herein for the transmission of power in motor vehicles. Power is transmitted in a smoother and more efficient manner by splitting torque into two or more torque paths. A continuously variable transmission is provided with a ball variator assembly having an array of balls, a planetary gearset coupled thereto and an arrangement of rotatable shafts with multiple gears and clutches that extend the ratio range of the variator. In some embodiments, clutches are coupled to the gear sets to enable synchronous shifting of gear modes.

摘要： 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.
