Abstract: A continuously variable transmission (CVT) may include differential and range modules that include planetary gear arrangements, a plurality of selectively engageable clutch assemblies, and a drop box module with a final output member. First and second power source paths may provide power to a same end of the differential module. The clutch assemblies may be selectively engageable 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 module may adapt the variable rotational power provided in the selected range for connection in a given application.

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 power system includes an engine, a driveshaft, and an energy storage system having a flywheel. The energy storage system further includes a transmission structured to transfer energy between the flywheel and the driveshaft. The transmission includes a differential geartrain and a variator coupled to the differential geartrain and having a variator input shaft and a variator output shaft rotatable at a range of speed ratios. The variator may be coupled to a sun gear in the differential geartrain and controls a pattern of energy transfer between the flywheel and the driveshaft.

Abstract: A centering device for centering a rotor shaft of a generator to a gearbox shaft of a gearbox in a genset assembly is disclosed. The centering device comprises a clamp assembly configured to be oriented on the rotor shaft and the gearbox shaft wherein the clamp assembly is further configured to be tightened to force the rotor shaft to coaxially align with the gearbox shaft. A method of using the centering device in a genset assembly to coaxially align the gearbox shaft with the rotor shaft of a generator is disclosed.

Abstract: An electric power system includes an engine, a generator, a drivetrain including a driveshaft, and an energy storage system having a flywheel. In an implementation, a parallel-path continuously variable transmission is structured to transfer energy between the flywheel and the driveshaft, and in another implementation a parallel-path continuously variable transmission transfers energy between the engine and the generator. The transmission includes a variator and a differential geartrain. An electric motor is coupled to the flywheel and charges the flywheel such that stored flywheel energy is available for bringing up engine speed from a standby state and/or to accommodate generator load changes with limited generator speed changes.
