Abstract: A high efficiency work vehicle drivetrain contains a variator having an inline dual planetary configuration. The work vehicle drivetrain includes an engine, an auxiliary power takeoff (PTO) shaft coupled to the engine and rotatable about a primary power path axis when driven by the engine, and the variator assembly. 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 planetary gear system is rotatable about a planetary axis, which is coaxial with the primary power path axis.

Abstract: High efficiency work vehicle drivetrains containing variator assemblies are provided. In one embodiment, the work vehicle drivetrain includes 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, in turn, 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 planetary gear system is rotatable about a planetary axis substantially parallel and offset from the primary power path axis.

Abstract: A work vehicle including an engine and a transmission. The transmission is driven by the engine. The transmission includes an input clutch, an output clutch, and a hydraulic pump/motor. The hydraulic pump/motor is operatively connected between the input clutch and the output clutch.

Abstract: A vehicle having a power generating device and a power transfer device. The power transfer device includes a plurality of gears in a housing within which the plurality of gears rotate. The plurality of gears include a first gear and a second gear, the first gear meshing with the second gear. The housing has a lubrication passage. The housing also has a lubrication slot and/or a spray nozzle in fluid communication with the lubrication passage. The lubrication slot and/or spray nozzle direct the fluid flowing therethrough toward where the first gear and second gear mesh.
