摘要： A power transferring gearset includes a gear synchronization controller disposed in communication with a drive gear, a driven gear and a shifting mechanism. In response to detecting a gear engagement command, the gear synchronization controller is configured to determine a rotational speed delta between a rotational speed of the drive gear and a rotational speed of the driven gear and compare the rotational speed delta to a pre-determined speed delta. In response to determining that the rotational speed delta is less than the predetermined speed delta, the gear synchronization controller applies a rotational shutter function to the drive gear to apply a series of clockwise and counterclockwise rotational cycles to the drive gear simultaneously during the axial movement of the shifting mechanism for preventing a blocked condition of the power transferring gearset while establishing the meshed relationship between the shifting and gear teeth.

摘要： A method for diagnosing a park function in a vehicle including a plurality of in-wheel motors each including first and second planetary gear sets includes, at a computing device, selectively engaging each of the first and second planetary gear sets in each of the plurality of in-wheel motors to place each of the in-wheel motors into a park state, engaging respective locking mechanisms of each of the in-wheel motors, when each of the first and second planetary gear sets is engaged and the respective locking mechanisms are engaged, determining whether a corresponding one of the in-wheel motors maintains the park state, and operating the vehicle in a selected one of a plurality of operating modes based on the determination of whether the corresponding one of the in-wheel motors maintained the park state.

摘要： A lubricant supported electric motor assembly includes an electric motor module, a shifting and first stage module, and a final drive module sequentially operably interconnected with one another for producing drive torque that is ultimately conducted to a wheel of a vehicle. The electric motor module includes a stator and a rotor defining an internal rotor cavity. The shifting and first stage module is disposed within the internal rotor cavity and includes a first planetary gear reducer assembly and an output gear selectively coupleable to said first planetary gear reducer assembly. The final drive module is disposed adjacent the shifting and first stage module and includes a second planetary gear reducer assembly operably coupled with the output gear. A shifting mechanism establishes selective coupling between the first planetary gear assembly and the output gear to transfer adjustable torque from the shifting and first stage module to the final drive device.

摘要： An e-axle assembly includes a housing extending from a first housing end to a second housing end to define an internal compartment. At least one electric motor is disposed in the internal compartment and includes a stator and a rotor rotatable relative to the stator about an axis. The rotor defines a hollow extending internally within the rotor, and at least one of a gearing mechanism, a shifting actuator, and/or a differential is disposed within the hollow (and thus packaged within the rotor). In a preferred arrangement, all and any of the gearing mechanisms, shifting actuators, and differential are disposed within the hollow of the rotor. This internal packaging of the drive components within the rotor reduces an overall space and weight of the e-axle assembly relative to the prior art designs to more easily and readily achieve the smaller space and weight allotments afforded by electric and/or hybrid vehicles.
