A method of controlling an EOP of a powertrain may include determining, by a controller electrically connected to the EOP, whether an oil sloshing phenomenon in which it is difficult for oil to return to a space where an oil intake port of the EOP is positioned may occur while a vehicle is running; and reducing, by the controller, the revolutions per minute (RPM) of the EOP by a predetermined reduced RPM when it is determined that the oil sloshing phenomenon may occur.

A bearing device includes a gear portion and a gear housing that houses the gear portion and stores a lubricant therein. The gear housing includes a side plate extending in a direction intersecting the axial direction, a recess recessed from the side plate toward the other side in the axial direction, a saucer opened upward, and a groove including a shaft opening opposing the gear housing and a peripheral opening opened to the recess. The gear portion includes an output shaft rotatably supported by the gear housing via a bearing, and a first gear connected to the output shaft. The saucer includes an opposing surface opposing an outer peripheral surface of the first gear. The groove is inclined downward toward the peripheral opening and reaches the bearing, and the shaft opening of the groove reaches the saucer.

A powertrain-cooling system of a hybrid vehicle may include an electric oil pump, a pressure control valve, which includes an input port receiving fluid discharged from the electric oil pump, an output port outputting the fluid to a transmission while adjusting the pressure of the fluid, and a drain port discharging a portion of the fluid in accordance with adjustment of the pressure of the fluid, a first motor cooling path connecting the drain port of the pressure control valve to a first motor forming a hybrid powertrain, and a controller electrically connected to the electric oil pump and configured for controlling the electric oil pump to cool the transmission and the first motor.

A drive device including: a motor; a transmission device including a reduction gear; a housing; an electric oil pump; and a control unit including a motor control unit and an electric oil pump control unit. The electric oil pump control unit includes: control mode switching means that, in oil supply processing, switches between and executes a normal control mode in which the output of the electric oil pump is changed in a plurality of stages according to the temperature of the stator or the rotor, and a startup mode in which the electric oil pump is operated at a maximum output in the normal control mode for a predetermined time at the start of power supply; and pump driving means that operates the electric oil pump.

Methods and systems are provided for integrating a gearbox into an electric motor. In one example, a system may include enclosing a gearbox containing a planetary gear set and a differential within an envelope of a rotor of the electric motor.

An outboard engine includes a steering mechanism having a pod propulsion device disposed in water outside a hull; a propulsive drive mechanism that is disposed in the hull and gives a propulsive drive force to the pod propulsion device; and a circulation cooling circuit which has an outward flow path that supplies a cooling oil to the steering mechanism and the propulsive drive mechanism, and an inward flow path which recovers the cooling oil from the steering mechanism and the propulsive drive mechanism, in which the inward flow path and the outward flow path of the circulation cooling circuit communicate with each other inside a case body of the pod propulsion device.

A transmission mechanism device includes a transmission mechanism including a hollow shaft, and a bearing supporting an outer face of the shaft. A holder holding the bearing is on the inner face of a housing of the transmission mechanism. The holder has a facing face facing an end of the shaft, a tubular portion holding the bearing and protruding in the axial direction radially from the facing face, and a rib inside the tubular portion and protruding in the axial direction from the facing face. The rib extends in a concave shape opening upward. A lower end of an inner face of the rib is below an upper end of an inner face of the shaft when viewed from the axial direction. At least one end of the rib in an extending direction faces an inner face of the tubular portion via a gap when viewed from the axial direction.

An integrated transmission includes a transmission housing having a first housing face through which the input shaft extends; a CVP housed within the housing; and a transmission assembly. The transmission assembly includes an input arrangement contained within the housing and having at least one input transmission component selectively coupling the engine power and the CVP power; a variator arrangement contained within the housing, configured to receive the engine and CVP power and to selectively transfer the engine power, CVP power, and a summing of engine and CVP power as variator output power; and a transmission gear arrangement contained within the transmission housing engaged with the variator arrangement and configured to provide a selective gear reduction for transmission to an output shaft that extends out of the transmission housing. The integrated transmission includes a power electronics apparatus arranged within or on the transmission housing and electrically coupled to the CVP.

A housing for a drive system. The housing defines a motor cavity, an electronics cold plate, an oil cavity, and a coolant cavity. The coolant cavity defines a first coolant flow path configured to provide cooling to the motor cavity and the oil cavity. The coolant cavity defines a second flow path configured to provide cooling to the motor cavity and the cold plate. The housing defines a coolant inlet and a coolant outlet fluidically coupled to the first coolant flow path and the second coolant flow path, such that the first coolant flow path and the second coolant flow path are parallel fluid paths. In some applications the coolant paths can be connected in series. In some examples, the housing is configured to cause a counter-flow heat exchange between an oil flowing in the oil cavity and a coolant flowing in the first coolant flow path.
