A transmission including an electric machine, a torque converter and a planetary gearset in a transmission housing that is connected to an engine. A turbine shaft is configured to transfer torque from the engine and the electric machine to the planetary gear set. A disconnect clutch selectively couples the input shaft from the engine to the torque converter housing of the torque converter. The disconnect clutch includes a disconnect clutch piston and a first balance dam. A torque converter clutch selectively connects the torque converter housing to the turbine and the turbine shaft. The torque converter clutch includes a torque converter clutch piston and a second balance dam. Ports in the housing permit automatic transmission fluid to flow between the turbine shaft and the torque converter clutch piston; the turbine shaft and the torque converter clutch piston; and the turbine shaft, the first balance dam, and the second balance dam.

Provided is a battery swap type hybrid power vehicle (100). The hybrid power vehicle (100) comprises a range extending type driving system formed of a range extender (10) and a driving motor (31), and further comprises a quick-swap battery (20) which can be quickly disassembled and swapped in a battery swap station. The quick-swap battery (20) is connected to the driving motor (31) to form a battery swap type driving system. The battery swap type driving system and the range extending type driving system can be quickly switched and independently serve as a main power system. The range extending type driving system taking the range extender (10) as a power source and/or the battery swap type driving system taking the quick-swap battery (20) as the power source can be freely and flexibly switched according to a use scene and economy to drive the vehicle to travel.

A hybrid drivetrain for a hybrid-driven vehicle, having a transmission, which can be shifted by shifting elements into different transmission steps, and which is connectable via an internal combustion engine shaft to an internal combustion engine, via an electric machine shaft to an electric machine, and via an output shaft to at least one vehicle axis. The internal combustion engine shaft and a pinion shaft, which can be connected with respect to drive to the output shaft, are connectable via spur gearwheel sets, which can be shifted by means of shifting elements and which each form wheel levels, of which at least one hybrid wheel level is additionally connectable to the electric machine shaft.

A vehicle driveline component includes a hollow motor shaft and a link shaft. The hollow motor shaft is supported for rotation about an axis including a plurality of grooves extending along an interior surface of the motor shaft. The link shaft cooperates with the interior surface of the motor shaft and the grooves to define a space between the link shaft and the motor shaft. The grooves are configured to force liquid lubricant to flow through the space in a longitudinal direction relative to the link shaft and the motor shaft when the motor shaft rotates. The link shaft includes a lubricant passage, a first connecting lubricant passage, and a second connecting lubricant passage. The lubricant passage extends along a longitudinal direction of the link shaft. The first and second connecting lubricant passages provide fluid communication between the longitudinal lubricant passage and the space.

A transmission for a hybrid vehicle may include an input shaft configured to receive power from an engine, a motor configured to receive power from a battery so as to generate the power by a regeneration, an output shaft configured to receive the power from the input shaft and the motor, and an idle shaft configured to connect the output shaft and the motor so as to receive driving force from the motor or transfer regenerative force to the motor.

A method includes controlling a torque output of an electric machine of an electrified vehicle based on estimated loads present during a transmission engagement of the electrified vehicle. Controlling the torque output may include merging a first feed-forward torque with a feedback torque if an input shaft of a transmission gearbox is spinning, or merging a second, different feed-forward torque with the feedback torque if the input shaft is not spinning.
