Variator for work vehicle drivetrain

The invention relates to a variator for a work vehicle drivetrain. A high-efficiency work vehicle drivetrain containing a variator assembly is provided. In one embodiment, the work vehicle drivetrainincludes an engine, a variator assembly, and an auxiliary power takeoff (PTO) shaft, which is coupled to the engine and rotatable about a primary power path axis when driven by the engine. The variator assembly includes a variator motor and a variator gearbox. The variator gearbox contains a planetary gear system, which is coupled to the variator motor and to the auxiliary PTO shaft. The planetarygear system is rotatable about a planetary axis substantially parallel and offset from the primary power path axis. 本发明涉及用于工作车辆传动系统的变速器。提供了包含变速器组件的高效率工作车辆传动系统。在个实施方式中，该工作车辆传动系统包括发动机、变速器组件和辅助动力输出(PTO)轴，所述辅助PTO轴联接到所述发动机并且当被所述发动机驱动时能围绕主动力路径轴线旋转。所述变速器组件又包括变速器马达和变速器齿轮箱。所述变速器齿轮箱包含与所述变速器马达和所述辅助PTO轴联接的行星齿轮系统。所述行星齿轮系统能围绕基本上平行于所述主动力路径轴线并从所述主动力路径轴线偏移的行星轴线旋转。
