Abstract: Systems and methods for an electric drive unit are provided. A transmission system in an electric drive unit includes first, second, and third input shafts rotationally coupled to first, second, and third electric machines, respectively, wherein the first and third electric machines are arranged on a first side of the transmission and the second electric machine is arranged on a second opposing side of the transmission. The transmission system further includes an idler shaft that connects the first, second, and third electric machines and couples to a sun gear of a planetary gear set. The planetary gear set is arranged between a first and second clutch wherein the first clutch couples to a carrier and the second clutch couples to a ring gear. An output shaft is spaced away from the planetary gear set via gear and includes two flanges to couple the transmission to outputs.

Abstract: Systems and methods for a power take-off (PTO) assembly. The PTO assembly, in one example, couples to a shaft and is driven by rotation of the shaft. The PTO assembly includes a disconnect clutch that selectively couples a bi-directional pump to the shaft. The disconnect clutch is passively actuated based on hydraulic system pressure to disengage the disconnect clutch when a prime mover is in operation and engage the disconnect clutch when the prime mover is shut down.
