摘要： In a hybrid transmission, a traction motor is mounted between a dry clutch module and a manual gearbox. A slave cylinder is mounted within the rotor of the traction motor to reduce axial length. The rotor is fixedly coupled to an engine crankshaft. The stator may be cooled by circulating engine coolant through the housing. The stator and the rotor may be cooled by spraying transmission fluid into a sealed motor cavity.

摘要： Methods and systems for improving operation of a vehicle driveline that includes an engine and an automatic transmission with a torque converter are presented. In one non-limiting example, the engine may be stopped while a vehicle in which the engine operates is rolling. A transmission coupled to the engine may be shifted as the vehicle rolls so that vehicle response may be improved if a driver requests an increase of engine torque.

摘要： A transfer case and transmission are designed to permit the transmission hydraulic control system to control a range selection coupler and a torque on demand clutch in the transfer case. Two pressure circuits are transmitted from the transmission to the transfer case: a high range circuit and a low range circuit. The low range circuit is pressurized to engage low range while the range circuit is pressurized to engage high range. The torque on demand clutch is controlled by whichever of these circuits has the higher pressure. Lubrication is provided to a front section of the transfer case via the transmission output shaft, with the fluid returning to the transmission sump through a drainback passageway. The rear portion of the transfer case has a segregated sump. A control strategy is employed to partially fill front section of the transfer case with fluid in preparation for vehicle towing.

摘要： A transmission includes a torque converter stator with controllable blade angle. A controller adjust the blades by commanding fluid pressures in hydraulic circuits routed to the stator hub. The controller also adjust the torque capacity of a torque converter bypass clutch by commanding fluid pressures in hydraulic circuits routed to apply and release chambers. Various schemes are presented to multiplex hydraulic circuits to serve multiple functions.

摘要： A vehicle powertrain includes a transaxle configured to drive front wheels and a power take-off unit configured to drive rear wheels through a driveshaft. The power take-off unit includes a disconnect clutch such that the power flow path to the rear wheels can be disconnected to reduce fuel consumption and reconnected when needed for traction enhancement. Although the disconnect clutch is physically located within the power take-off unit, it is actuated by fluid from the transaxle valve body. The disconnect clutch actuator includes a piston that slides within a chamber in a housing and a solenoid controlled valve that fluidly connects the chamber either to a pressure source or to the transaxle sump.
