使用单个行星齿轮的多模式混合变速器
摘要：
变速器包括单个行星齿轮组、第一扭矩机、输出构件和耦接至驱动构件的双速齿轮组。单个行星齿轮组包括太阳齿轮、行星架齿轮组和环形齿轮，其中行星架齿轮组可旋转地耦接至输入构件并可旋转地耦接至输出构件，太阳齿轮可旋转地耦接至第一扭矩机的转子，且环形齿轮可旋转地耦接至输入构件并可旋转地耦接至输出构件。输出构件可旋转地耦接至双速齿轮组，所述双速齿轮组被配置成以第一齿轮比和第二齿轮比中的一个进行操作。
摘要（英）：

A transmission includes a single planetary gearset, a first torque machine, an output member and a two-speed gearset that is coupled to the drive member. The single planetary gearset includes a sun gear, a carrier gearset and a ring gear, wherein the carrier gearset is rotatably couplable to the input member and rotatably couplable to the output member, the sun gear is rotatably coupled to a rotor of the first torque machine, and the ring gear is rotatably couplable to the input member and rotatably couplable to the output member. The output member is rotatably couplable to the two-speed gearset, which is configured to operate in one of a first gear ratio and a second gear ratio.
