Bearings (72, 74) are arranged for a drive unit (10) having an electric motor for providing drive to an electric axle and a wheel assembly of a vehicle. The drive unit includes a pair of bearings and a reduction gear assembly (12) with a first drive gear mounted to and coaxial with the main shaft of the motor, and a first driven gear rotatably coupled to the first drive gear and mounted to and coaxial with an intermediate shaft to form an intermediate shaft assembly. The reduction gear assembly includes a second drive gear mounted to and coaxial with the intermediate shaft, and a second driven gear rotatably coupled with the second drive gear. A first bearing of said pair of bearings is mounted to a bulkhead and to said intermediate shaft assembly between the first driven gear and second drive gear to reduce the distance between the first and second bearings.

A gear shifting apparatus in a new energy vehicle includes a primary power transmission unit, a secondary power transmission unit, an intermediate shaft, an intermediate shaft gear, a first clutch unit, a second clutch unit, and a third clutch unit. The intermediate shaft gear is fixedly sleeved on the intermediate shaft, and the first clutch unit is disposed between the intermediate shaft and the primary power transmission unit. The second clutch unit is disposed between the intermediate shaft and the secondary power transmission unit. The third clutch unit is disposed between the primary power transmission unit and the intermediate shaft gear.

A gearbox for a vehicle includes a primary shaft configured to rotate about a first axis, a distribution gear, a transmission gear arranged around the primary shaft, an auxiliary shaft configured to rotate around a second axis, an auxiliary output gear and an auxiliary transmission gear arranged around the auxiliary shaft, an output gear arranged around the primary shaft for transmitting a power out of the gearbox, and a gear shift system slidable between at least two positions. The gear shift system is configured to rotationally engage the distribution gear and the output gear for transmitting the power directly from the primary shaft to the output gear, or the distribution gear and the transmission gear for transmitting the power indirectly from the primary shaft to the output gear through the auxiliary shaft.

A drive assembly for a work vehicle includes a drive housing, a drive shaft rotatable about a drive axis, an inner hub rotationally fixed to the drive shaft, and a planetary gear set coupled to the drive shaft and configured to selectively rotate an output element. The drive assembly also includes a clutch arrangement having a clutch ring configured to selectively engage the planetary gear set. The clutch arrangement further includes a guide assembly mounted on the clutch ring and configured to selectively interact with the planetary gear set to effect disengagement of the clutch ring from the planetary gear set. A clutch actuation assembly is configured to effect movement of the clutch arrangement along the drive axis to engage the planetary gear set, and a guide actuation assembly is configured to operate the guide assembly to interact with the planetary gear set.

A powertrain apparatus includes a motor connected to an input shaft, a first planetary gear train, which is disposed to be coaxial with the motor and which includes a first rotation element, a second rotation element, and a third rotation element, a second planetary gear train, which is disposed to be coaxial with the first planetary gear train and which includes a fourth rotation element, a fifth rotation element, a sixth rotation element, and a step pinion, and a differential gear, which is disposed to be coaxial with the second planetary gear train.

A method for operating a motor vehicle drivetrain having a transmission connected between a drive aggregate and a drive output, a Power Take-Off (PTO) that can be coupled to the drive aggregate on drive aggregate side to take up drive torque from the drive aggregate. In order to determine the torque taken up by the PTO, the transmission is first shifted to interrupt torque to the transmission output. Thereafter, a defined torque is delivered by the drive aggregate, at least with the PTO coupled to the drive aggregate, and, during this at defined time-points, rotational speeds of a shaft driven by the drive aggregate are determined and from this an angular acceleration of the shaft is determined. A first torque of the shaft is determined from the shaft angular acceleration while the PTO is coupled. Based on the first torque, the torque taken up by the PTO is determined.

A drive axle of an electric vehicle has first and a second drive wheels (R1, R2) with wheel axles (a1, a2), a first electric machine (EM1) and a second electric machine (EM2) with a common rotation axis (m), a transmission (G3) with a transmission input shaft (EW) and a transmission output shaft (AW), and an axle differential (DI) with a differential input (DIK) and two differential output shafts (3a, 3b). The first electric machine (EM1) is connected to the transmission input shaft (EW) and the transmission output shaft (AW) is connected to the differential input (DIK). The second electric machine (EM2) can be connected as an additional drive when necessary.
