To provide a compact configuration, the first electric motor and the first gear train are sandwiched between the sun gear and the planet gears.

The disclosure relates to a transmission comprising an input shaft, a first output shaft, a second output shaft, a first planetary gear set, and a second planetary gear set which is connected to the first planetary gear set. Each of the planetary gear sets comprise multiple elements, wherein the first output shaft is rotationally fixed to a second element of the first planetary gear set, the second output shaft is rotationally fixed to a third element of the second planetary gear set, a third element of the first planetary gear set is rotationally fixed to a first element of the second planetary gear set via a shaft, and a second element of the second planetary gear set is secured to a rotationally fixed component. The transmission additionally comprises a third planetary gear set comprising three elements and two shift elements, wherein a first shift element is designed to block the third planetary gear set by connecting two elements of the third planetary gear set in a rotationally fixed manner, a second shift element is designed to secure a first element of the third planetary gear set to the rotationally fixed component, a second element of the third planetary gear set is rotationally fixed to the first element of the first planetary gear set via an intermediate shaft, and a third element of the third planetary gear set is rotationally fixed to the input shaft.

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.

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 driveline component includes a first plate and a second plate. A motor is engaged with the first plate. The first plate and the second plate include ramped grooves that ramp toward the other of the first plate and the second plate. Balls are disposed between the first plate and the second plate and are engaged with the ramped grooves. A shifter is engaged with the second plate. Relative rotation of the first plate and the second plate causes the balls in the ramped grooves to move the first plate and the second plate axially relative to each other. This relative rotation may be used to make one type of mode selection, and operation of the shifter by the second plate may be used to make another type of mode selection. This allows the single motor to make both selections.
