    Abstract: Transmission for coupling to hydromechanical power source includes differential and range modules including planetary gear arrangements, a plurality of selectively engagable clutch assemblies, and a drop box module, which includes a final output member. First and second power source paths provide power to the differential module. The clutch assemblies are selectively engagable to provide variable rotational power from the differential module to the range module, and from the range module to the drop box module in a plurality of directional ranges. The drop box adapts the variable rotational power provided in the selected range for connection in a given application.

    Abstract: A clutch assembly is provided. The clutch assembly includes a basket member, an input member and an actuator that is disposed within the basket member. A hub member, having a hub spline and an inclined portion is disposed adjacent to the actuator. A cam member, having a cam spline and cam lobes is rotatably disposed on the input member. A shaft member, having a shaft spline and plurality of slots is rotatably disposed on the input member. The hub spline is engaged with the cam spline in a disengaged position of the actuator. The clutch assembly further includes a plurality of balls received within the corresponding slots of the shaft member. While moving towards an engaged position of the actuator, the cam spline aligns with the shaft spline thereby the hub spline engages with the shaft spline in the engaged position of the actuator.

    Abstract: A variable drive system of a power system is disclosed. The variable drive system may include an engine gearset to transfer power from an engine output of an engine to a variable input driveshaft of the variable drive system. The variable drive system may include a generator gearset to transfer power, generated by the engine, to a generator driveshaft of a generator. The variable drive system may include a variable drive, coupled to the variable input driveshaft, to enable a gear ratio between engine output and the generator driveshaft to be adjustable, the variable input driveshaft being offset from at least one of the engine output or the generator driveshaft. The variable drive system may include a direct drive clutch to bypass variable power transfer through the variable drive and enable direct power transfer from the engine output to the generator driveshaft.

    Abstract: A transmission system for a machine is coupled to an engine of the machine that is adapted to generate power. The transmission system includes a hydraulic power path including a variator coupled to the engine. The transmission system also includes a mechanical power path. The mechanical power path includes a first gear arrangement including a plurality of gears. The mechanical power path also includes a second gear arrangement including a plurality of gears. The second gear arrangement is coupled with the first gear arrangement to receive the variable rotational power from the first gear arrangement. The mechanical power path further includes a first clutch assembly and a second clutch assembly. Further, the second gear arrangement directs the variable rotational power received from the first gear arrangement towards a final output member of the machine in a selected direction.
