The invention provides a powersplit hybrid transaxles.This disclosure describes powersplit hybrid transaxles for hybrid vehicles. An exemplary hybrid transaxle may include a dual sprocket assembly at least partially disposed between an engine and a first electric machine (e.g., a generator). A power transfer unit, such as a planetary gear set, may be nested within the dual sprocket assembly. Chains may operatively connect the power transfer unit to driven sprockets of a second electric machine (e.g., a traction motor) and a differential to provide torque to vehicle drive wheels. The proposed hybrid transaxles provide improved efficiency and compact packaging configurations.
本公开提供了“功率分流混合动力变速驱动桥”。本公开描述了用于混合动力车辆的功率分流混合动力变速驱动桥。示例性混合动力变速驱动桥可以包括至少部分地设置在发动机与第一电机(例如,发电机)之间的双链轮总成。动力传递单元(诸如行星齿轮组)可以嵌套在双链轮总成内。链条可以将动力传递单元可操作地连接到第二电机(例如,牵引马达)的从动链轮和差速器,以向车辆驱动轮提供扭矩。所提出的混合动力变速驱动桥提供了更高效率和紧凑的包装配置。
