Title (EN) ELECTRIC AXLE TRANSMISSION WITH A BALL VARIATOR CONTINUOUSLY VARIABLE PLANETARY TRANSMISSION WITH AND WITHOUT TORQUE VECTORING FOR ELECTRIC AND HYBRID ELECTRIC VEHICLES
(FR) TRANSMISSION D'ESSIEU ÉLECTRIQUE AVEC UNE TRANSMISSION PLANÉTAIRE À VARIATION CONTINUE DE VARIATEUR À BILLES AVEC ET SANS VECTORISATION DE COUPLE POUR VÉHICULES ÉLECTRIQUES ÉLECTRIQUES ET HYBRIDES
Abstract:
(EN) 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.
(FR) L'invention concerne un groupe motopropulseur d'essieu électrique comportant une transmission électrique à variation continue comprenant un moteur/générateur et un planétaire à variation continue de type à billes ayant un premier ensemble de bague de traction et un second ensemble de bague de traction en contact avec une pluralité de billes; un essieu de roue d'entraînement couplé en fonctionnement à la transmission électrique à variation continue; et une première roue et une seconde roue couplées à l'essieu de roue d'entraînement. Selon certains modes de réalisation, les transmissions électriques à variation continue comprennent un ou plusieurs ensemble(s) d'engrenages pour fournir des schémas de puissance qui réduisent le couple à travers le planétaire à variation continue de type à billes. Selon certains modes de réalisation, les transmissions électriques à variation continue comprennent des configurations d'engrenage pour réduire la vitesse à travers le planétaire à variation continue de type à billes. Selon certains modes de réalisation, les essieux électriques sont dotés de configurations d'engrenage qui permettent une vectorisation de couple.
