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 powertrain system in a machine includes a transmission, and a transmission drive mechanism coupled between the transmission and an engine. The transmission drive mechanism includes a split path architecture where a first input gear receives a torque input from a driveshaft and a second input gear receives a torque input from a variator. The transmission drive mechanism is thereby structured to operate the transmission at a range of speeds that is not dependent upon a speed of the engine, enabling the engine to operate at an engine speed set point or with an optimum engine speed range.
