Powertrain, Vehicle, and Method With Electric Motors and Dual Belt Drive

摘要

Electric vehicle powertrains, highway vehicles, and methods of manufacturing vehicles have dual belts driving wheels from two electric motors. Embodiments have a centrally-located transmission housing containing two belts and pulleys, and motors are mounted outside of the housing. A battery may power the motors and an internal combustion engine may power wheels on the other end of the vehicle through a separate transmission. Each belt may have a tensioner and drive shafts may have universal joints and decouplers. The transmission may have a central wall or supports which may support the pulleys and adjacent pulleys may have a common centerline and be supported by a common pin through the central wall.
