摘要： A drive unit includes a motor, a torque converter, a torque transmission member, first and second transmission paths, first and second gear trains, and a controller. The torque converter amplifies torque directed in a first direction. The first transmission path transmits torque through the torque converter. The second transmission path transmits torque without through the torque converter. The first gear train outputs torque directed in the first direction as forward torque. The second gear train outputs torque directed in the first direction as reverse torque. The controller executes a first forward moving mode such that the motor is rotated in the first direction, and torque is outputted through the first transmission path and the first gear train. The controller executes a second forward moving mode such that the motor is rotated in a second direction, and torque is outputted through the second transmission path and the second gear train.

摘要： A viscous clutch (20) includes a housing assembly (28), a rotor assembly (26), a reservoir (38) to hold a supply of a shear fluid, a working chamber (40) operatively positioned between the housing assembly and the rotor assembly, and a fluid return bore (26-1B) that optionally extends radially through at least an outer diameter portion of the rotor assembly to the working chamber. Selective introduction of the shear fluid to the working chamber facilitates selective torque transmission between the housing assembly and the rotor assembly. The fluid return bore can form at least a portion of a fluid return path (50) from the working chamber to the reservoir.

摘要： A geartrain for a powertrain system is disposed to transfer mechanical power between an internal combustion engine, an electric machine and a driveline. The geartrain includes a flywheel, a torque converter, an off-axis mechanical connection and a transmission gearbox. The off-axis mechanical connection includes a first element rotatably coupled to a second element. The flywheel is coupled to a crankshaft of the internal combustion engine. The torque converter includes a pump, a turbine and a pump hub, and the transmission gearbox includes an input member. The pump of the torque converter is coupled to the flywheel, and the pump hub is coupled to the first element of the off-axis mechanical connection. The second element of the off-axis mechanical connection is coupled to a rotor of the electric machine, and the turbine of the torque converter is coupled to the input member of the transmission gearbox.

摘要： A device for transmitting a rotation movement includes first and second force transmission sections, each with a drive input and a drive output, and with a first chain guide. The chain guide is arranged between the drive input and output and accommodates an endless chain, which circulates between the drive input and drive output. A middle force transmission section with a middle drive input and a middle drive output, and with a conduit that is arranged between these. The conduit accommodates a hydraulic fluid and transmits forces between the first and the second force transmission section. The hydraulic fluid circulates between the middle drive input and the middle drive output and transmits push forces between the middle drive input and the middle drive output. The first drive output is coupled to the middle drive input, and the middle drive output is coupled to the second drive input.
