Abstract: Methods and systems for a multi-ratio gear box and a countershaft power-shift transmission are provided. The system contains one or more electric motors coupled to a transmission housing in such that the electric motor does not exceed the highest point of the transmission. A first shaft may be coupled to one or more input speed reduction gear sets. A second shaft may be coupled to a multi-range clutch allowing two speeds. A third shaft may be coupled to a low-speed clutch and a fourth shaft may be coupled to a high-speed clutch, together doubling the number of speeds. The high and low speed clutches provide a large gear spread that allow the twin range clutches to have a reduced gear spread, overall reducing the required size of the transmission system.

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 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: An electric axle and electric axle product line. The electric axle includes, in one example, a multi-speed gearbox assembly rotationally coupled to a first electric machine and including a first shaft with a first clutch positioned coaxial thereto and a second shaft with a second clutch positioned coaxial thereto. In the multi-speed gearbox assembly, the first clutch and the second clutch are parallel to one another and configured to alter the unit's operating gear ratio.

Abstract: Methods and systems are provided for a transmission. In one example, the transmission includes electric motor arranged on both sides thereof. In at least one example, electric motors on opposite sides of the transmission are coupled to a single input shaft.

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 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.
