Abstract: A transfer case pump includes an oil pump, a cover assembly, and a torque transfer mechanism. The oil pump has a pump shaft, and is configured to pressurize a lubricant in response to a rotation of the pump shaft. The pump shaft rotates around a pump axis. The pump axis is parallel to a rear axis of a rear shaft. The pump axis is offset from the rear axis. The cover assembly has a channel configured to transfer the lubricant from the oil pump to the rear shaft. The cover assembly extends around the rear shaft and around the pump shaft. The torque transfer mechanism is configured to transfer a torque from the rear shaft to the pump shaft.

Abstract: A drive torque transfer case is provided. The transfer case includes an input shaft, an output shaft, a gear assembly coupled to the input shaft, and a range clutch assembly coupled to the output shaft. The range clutch assembly includes a clutch member and a multi-piston actuator configured to receive a pressurized transmission fluid for selectively axially translating the clutch member to engage a component of the gear assembly for transmitting a drive torque from the input shaft to the output shaft. The multi-piston actuator includes an internal piston having a first annular surface area A1 and a third annular surface area A3, and an external piston having a second annular surface area A2 and a fourth annular surface area A4. The A1 and A2 are in hydraulic communication with a first hydraulic chamber, and A3 and A4 are in hydraulic communication with a second hydraulic chamber.

Abstract: An automatically-shiftable transaxle includes an input member configured to receive an external power-source torque and rotate about a first axis. The transaxle also includes torque transmitting device(s) and a gear-train, each operatively connected to the input member for selecting transaxle speed ratios, and a first transfer gear operatively connected to the gear-train and rotatable about the first axis. The transaxle also includes an intermediate shaft rotatable about a second axis, and a second transfer gear rotatably fixed to the intermediate shaft and meshed with the first transfer gear. The transaxle additionally includes an electric motor arranged on a third axis for providing a torque input to the second transfer gear. Furthermore, the transaxle includes a differential assembly operatively connected to the intermediate shaft and rotatable about a fourth axis to thereby transmit a transaxle output torque to drive the load. All four transaxle rotational axes are arranged in parallel.

Abstract: A transmission sealed low leak controls system includes a controls system having a first fluid for operation of the controls system provided by a first pump at a first pressure. A transmission input shaft is provided. A planetary gear set is connected to the transmission input shaft by a clutch assembly. A second pump provides a second fluid different from the first fluid for cooling and lubrication of the at least one clutch assembly at a second pressure lower than the first pressure. A torque converter is connected to the transmission input shaft. The second pump further provides the second fluid to the torque converter.
