Abstract: An electric drive axle with an electric motor having a motor shaft that is rotatable about an axis, a differential, and a transmission. The transmission transmits rotary power between the motor shaft and the differential. The multi-speed reduction has an input shaft and at least three on-axis gears. The input shaft is rotatably coupled to the motor shaft. Each of the at least three on-axis gears is co-axial with the input shaft and is rotatable relative to the input shaft in at least one of a first speed ratio and a second speed ratio. The input shaft is axially movable along the axis between a first position, in which a first one of the at least three on-axis gears is rotationally coupled to the input shaft, and a second position in which a second one of the at least three on-axis gears is rotationally coupled to the input shaft.

The first, second and third gears can be engaged by way of the hydrodynamic torque converter (1) while the fourth, fifth and sixth gears can be engaged without the hydrodynamic torque converter (1). For this, the input shaft (6) is connected to the turbine (14) and the driveshaft (7) can be directly connected to the drive engine. The driveshaft (7) is located inside the input shaft (6).

Abstract: A dual clutch transmission is provided with first and second coaxial input shafts, at least one mainshaft, and an output shaft that are coaxial with one another. The transmission has a countershaft offset from the first input shaft that supports seven countershaft gear elements drivably connected to respective gear elements on the first and second input shafts and the at least one mainshaft thereby forming seven forward gear meshes for the transmission. The seven forward gear meshes provide at least nine forward gear ratios for the transmission. The transmission is powershiftable between consecutive gear ratios of the at least nine gear ratios such that no torque interrupt occurs during sequential shifts.
