    Abstract: A planetary system, which may be found in an automotive transmission, is provided. The planetary system may include a sun gear, a plurality of pinion gears that are operably coupled to the sun gear and carried by a carrier, and a ring gear operably coupled to the plurality of pinion gears. The carrier may include a plurality of spaced apart side walls and a plurality of circumferentially spaced apart posts that interconnect the side walls. The plurality of posts and side walls may be unitary with one another. Further, at least one of the posts may include an oil delivery channel and an oil exit channel in fluid communication with one another.

    IPC: F16H3/72

    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 first gear train, second gear train, and clutch are arranged downstream from the first electric motor and second electric motor.

    IPC: F16H63/34

    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 which may be separated into individual drive modules, optionally in separate detachable housings. 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 earth 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 drive system for a hybrid or electric vehicle that includes a transmission with four forward and four reverse gears. The transmission optionally includes a first and a second planetary gearset, and optionally a first and second range selector assembly. The range selector assemblies may include a clutch and a brake, and/or a synchronizer. The drive system may include a single electric motor with any example of a transmission of the present disclosure, or multiple electric motors individually driving separate transmissions. The 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, input shaft, output shaft, and any suitable combination thereof. An internal combustion engine may be included as well.
