摘要
An electric axle powertrains having a continuously variable electric drivetrain including a motor/generator and a ball-type continuously variable planetary having a first traction ring assembly and a second traction ring assembly in contact with a plurality of balls; a drive wheel axle operably coupled to the continuously variable electric drivetrain; and a first wheel and a second wheel coupled to the drive wheel axle. In some embodiments, the continuously variable electric drivetrains include one or more gear sets to provide power paths that reduce torque through the ball-type continuously variable planetary. In some embodiments, the continuously variable electric drivetrains include gearing configurations to reduce speed through the ball-type continuously variable planetary. In some embodiments, the electric axles are provided with gearing configurations that enable torque vectoring.
