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.
