Abstract: Systems and methods for an electric drive unit are provided. A transmission system, in one example, includes a higher-lower range clutch assembly positioned downstream of a multi-speed clutch assembly and designed to shift the transmission system between a higher range operating mode and a lower range operating mode. The higher-lower range clutch assembly includes a lower range clutch and a higher range clutch each positioned on one of a first layshaft and an output shaft.

Abstract: Systems and methods for a multi-speed electric axle. The multi-speed electric axle includes an electric motor that is rotationally coupled to an input shaft. The multi-speed electric axle also includes a planetary gearset connected to the input shaft via an input gear reduction, a lower-speed clutch that selectively grounds a ring gear in the planetary gearset to a housing, and a higher-speed clutch that selectively connects a sun gear to a carrier.

Abstract: Systems and methods for an electric drive unit are provided. A transmission system in an electric drive unit, in one example includes an input shaft rotationally coupled to each of a first electric machine and a second electric machine and a first clutch arranged coaxial to a first countershaft, where a first gear is fixedly coupled the first clutch and meshes with a second gear that is fixedly coupled to the input shaft. The transmission system further includes a second clutch arranged coaxial to a second countershaft and spaced away from the first countershaft and a third gear that is fixedly coupled to the second clutch and meshes with the first gear, where the first clutch and the second clutch are configured to shift the transmission system between multiple gear ratios and deliver mechanical power to an output shaft that is spaced away from the second countershaft.

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.
