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: Transmissions, park systems, and methods of operating transmissions are disclosed. 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: 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.

Abstract: A multi-speed transmission may include a plurality of planetary gearsets and a plurality of selective couplers. The plurality of planetary gearsets may include a first planetary gearset, a second planetary gearset, a third planetary gearset, a fourth planetary gearset, and a fifth planetary gearset. The plurality of selective couplers may include a number of clutches and a number of brakes. The multi-speed transmission may have five planetary gearsets and seven selective couplers. The seven selective couplers may include two clutches and five brakes or three clutches and three brakes.

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 transmission system efficiently performs efficiently and also provides the ability to perform full-power shifts. For example, a secondary clutch actuator, independent of fluid actuation, may eliminate the need for a pump to continuously provide high pressure during regular vehicle operation such that high pressures are only required during a shift event. This eliminates the need for energy at the pump to maintain application of the clutch, thereby allowing such energy to be used of other systems in the EV or to facilitate increased vehicle range.
