Abstract: 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 first gear train that has an interruptible connection with the drive shaft. In one form, this interruptible connection includes a second carrier and a clutch engagement member. 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.

Abstract: A drive system for a hybrid or electric vehicle that includes a transmission with three forward and three reverse gears. The transmission optionally includes a first and a second planetary gearset, a first and a second clutch, and a brake. The system may be configured to separately engage these components in concert. The drive system may include a single electric motor with a corresponding transmission, or multiple electric motors individually driving separate transmissions. Motors may be arranged upstream or downstream of portions of a transmission, and they may be aligned parallel with or perpendicular to a drive axle.

Abstract: Transmissions, park systems, and methods of operating transmissions are disclosed herein. A transmission includes an input shaft to receive torque from a drive unit, an output shaft to transmit torque to a load, and a park system to selectively brake the output shaft. The park system includes a park actuation assembly having a park gear in direct contact with the output shaft, an actuator to supply rotational power, and an actuation linkage coupled between the actuator and the park actuation assembly.

Abstract: A drive system for a vehicle that includes a transmission with three forward and three reverse gears. The transmission is optionally coupled to an electric motor as part of a fully electric or hybrid drive system. The transmission optionally includes a first and a second planetary gearset, a first and a second brake, and a clutch. The system may be configured to separately engage the first or second brakes, or the clutch, and may be arranged to provide separate gear ratios as each is engaged and disengaged separately. A single electric motor may be provided with a single transmission, or multiple electric motors may be included to individually drive multiple separate tires, tracks, or other ground engaging elements. Single or multiple motors may be arranged upstream or downstream of the transmission, and they may be aligned parallel with or perpendicular to a drive axle.

Abstract: A rotatable transmission component rotatable about an axis of rotation includes a first mounting member spaced apart from a second mounting member and a spindle extending from the first mounting member to the second mounting member. An axial location of the spindle between the first and second mounting members is maintained by interference connections between the spindle and the first and second mounting members. An outer diameter of a first end of the spindle is larger than an outer diameter of a second end of the spindle. The rotatable transmission component may be a planet carrier, and a planet gear may be supported on the spindle.
