A drive device includes: an oil pump; a first rotation transfer member drivably coupled to the oil pump and driven by at least one of an internal combustion engine and a rotary electric machine; and a second rotation transfer member drivably coupled to wheels and driven by the rotary electric machine. One of the first rotation transfer member and the second rotation transfer member is a pinion. The other rotation transfer member is a carrier that rotatably supports the pinion. The pinion and the carrier are rotated together with each other in the case where the oil pump is driven by the rotary electric machine.

Drive device that transfers rotation of at least one of a rotary electric machine and an internal combustion engine to an oil pump

A hybrid drive device having an engine coupling shaft member, a speed change mechanism, a rotating electrical machine, and an engine connecting clutch. A first lubricating oil passage scatters lubricating oil from radially inside to radially outside of first and second friction plates. A first one-way clutch is interposed between an engine coupling shaft member and a coupling member, and is configured to not be engaged when rotation of the engine coupling shaft member becomes lower than rotation of the coupling member. A second one-way clutch is configured not to be engaged when rotation of the rotating electrical machine becomes lower than rotation of the coupling member. An engine driven oil pump generates an oil pressure to be supplied by a driving force of the internal combustion engine or a driving force of the rotating electrical machine regardless of engagement or disengagement of the engine connecting clutch.

Hybrid drive device

A hybrid drive device having a clutch that engages and disengages an output member of an internal combustion engine and an input shaft of an automatic transmission device with and from each other. A rotary electric machine has a stator fixed to a case and a rotor coupled to the input shaft of the automatic transmission device. The rotary electric machine is disposed radially outwardly of the clutch so as to at least partially overlap the clutch in an axial direction as seen from a radial direction. Lubricating oil is supplied from the input shaft of the automatic transmission device to the clutch and the hybrid drive device includes a shield portion that allows the lubricating oil to bypass the rotary electric machine and leads the lubricating oil supplied to the clutch to an oil reservoir.

A friction-plate lubricating device for an automatic transmission that includes a friction engagement element with a plurality of friction plates in which outer friction plates and inner friction plates are alternately disposed; a hub with splines engaged with teeth formed on an inner circumference of the inner friction plates, the hub having the splines on an outer circumference thereof and having uneven portions formed on an inner circumference thereof; and a nozzle that discharges lubricant to the uneven portions. Recesses of the uneven portions serve as oil reservoirs in which the lubricant gathers, and through-holes are formed in bottom surfaces of the recesses. The lubricant discharged from the nozzle is collected in the oil reservoirs formed by the recesses so as to be supplied to the plurality of friction plates of the friction engagement element through the through-holes.

Friction-plate lubricating device for automatic transmission

A speed change device configured with an input member and an output member. The speed change device includes a speed change mechanism in which a plurality of shift speeds are established in accordance with respective engagement states of a plurality of friction engagement elements to transfer rotation of the input member to the output member. A slip travel mode is provided in which the vehicle is run while transferring torque from the input member to the output member with one of the friction engagement elements for establishment of each of the shift speeds caused to slip. A slip engagement element is the friction engagement element to be engaged commonly for establishment of at least a forward start shift speed and a reverse start shift speed.
