The electric powertrain further includes a sun gear in the form of a ring gear and planet gears in the form of a first output shaft. To provide a compact configuration, the first electric motor and the first gear train are sandwiched between the sun gear and the planet gears.

A drive device includes a motor, a housing, an oil passage in the housing, an oil pump in which a portion of the oil passage is provided, and a strainer inside the housing and in which a portion of the oil passage is provided. The oil passage includes an oil sump in which oil is accumulated and a suction path connecting the oil sump and the oil pump. A central axis of the oil pump extends in a direction intersecting the vertical direction. The strainer is in the suction path. The strainer includes a suction port to suction oil from the oil sump, a discharge port to discharge oil toward the oil pump, and a filter. The suction port opens downward in the vertical direction. The discharge port opens in a direction intersecting the vertical direction toward the oil pump.

A gearbox comprising: an outer intermediate shaft carrying a first set of shaft gears; an inner intermediate shaft carrying a second set of shaft gears, the inner intermediate shaft running concentrically within the outer intermediate shaft; a first lay shaft carrying a first set of drive gears and an output gear positioned along the first lay shaft between two of the first set of drive gears, a second lay shaft carrying a second set of drive gears and an output gear positioned along the second lay shaft between two of the second set of drive gears, each drive gear being coupled to a respective shaft gear to together provide a plurality of gear ratios between the intermediate shafts and the output shaft; and an output shaft, each lay shaft being coupled to the output shaft by the respective output gear.

An electric powertrain includes a first electric motor that has an uninterrupted connection with a drive shaft of a vehicle. The electric powertrain further includes a second electric motor that has an interruptible connection with the drive shaft. In one form, this interruptible connection includes a clutch. The electric powertrain further includes a first gear train in the form of a first planetary gear and a second gear train in the form of a second planetary gear. The clutch in one variation includes a positive clutch in the form of a dog clutch. The dog clutch has a clutch suspension configured to deflect a clutch collar when gearing is misaligned during shifting.

An axle assembly that includes a barrel cam. The barrel cam may be rotatable about a barrel cam axis and may be operatively connected to a first shift collar. Rotation of the barrel cam about the barrel cam axis may control movement of the first shift collar along a first axis.

A power transmission device includes a motor having a motor shaft, a transmission mechanism, a reduction gear, and a case member. The transmission mechanism is connected downstream of the motor. The transmission mechanism has a band brake, and an actuator. A reduction gear is arranged downstream of the transmission mechanism. The case member houses the motor, at least a part of the transmission mechanism, and the reduction gear. The case member has an outer circumference wall that surrounds an outer circumference with respect to a radial direction perpendicular to a rotation axis of the motor shaft, and a side wall that is linked to the outer circumference wall, and that extends outwardly in the radial direction from the outer circumference wall. The actuator is provided adjacent to the outer circumference wall, and adjacent to the side wall, the actuator overlapping with the band brake in the radial direction.

A drive device that rotates an axle of a vehicle includes a motor, a decelerator connected to the motor, a differential connected to the motor via the decelerator, a housing that accommodates the motor, the decelerator, and the differential, an oil pump to send, to the motor, oil accommodated in the housing, and a controller to control the motor. The controller drives the oil pump after the ignition switch of the vehicle is turned off.

An engine transmission is provided with an interference member that is configured to interfere with one of a low-gear clutch sleeve and a high-gear clutch sleeve so that when one of the low-gear clutch sleeve and the high-gear clutch sleeve is at an engagement position, the other one of the low-gear clutch sleeve and the high-gear clutch sleeve cannot move to an engagement position.

A transmission arrangement (16) for an at least partially electrically driven vehicle (1) includes a first electric machine (3a) defining a first central longitudinal axis (9a) and having a first gear stage (6a) and a second gear stage (7a). The arrangement further includes a second electric machine (3b) defining a second longitudinal axis (9b) and having a first gear stage (6b) and a second gear stage (7b). Further, the arrangement includes a transmission housing (2), with the first and second electric machines (3a, 3b) being arranged in the transmission housing (2). Additionally, the arrangement includes a differential (8) drivingly connected to the second gear stages (7a, 7b) of the first and second electric machines (3a, 3b). The first and second central longitudinal axes (9a, 9b) are axially parallel to each other on a circular path (10) perpendicular to an output axis (5).

A transaxle includes a first motor generator, a second motor generator, a first planetary gear train, a second planetary gear train, a ring gear shaft, and a case. The first planetary gear train includes a first sun gear, a first carrier, and a first ring gear. The second planetary gear train includes a second sun gear, a second carrier, and a second ring gear. The first sun gear is coupled to the first motor generator, and the first ring gear is coupled to the ring gear shaft. The second sun gear is coupled to the second motor generator, and the second ring gear is coupled to the ring gear shaft. The first carrier and the second carrier are not rotatable relative to the case.
