A vehicle drive includes a speed change mechanism connected to a rotary electric machine; an output member connected to the speed change mechanism and wheels; an engagement device changes a state of engagement between an input member connected to an engine and the speed change mechanism; a hydraulic pump driven by the engine or the rotary electric machine; a first pressure control device that controls pressure supplied from the pump and supplies the pressure to the speed change mechanism; a second, separate hydraulic pressure control device that controls the pressure supplied from the pump and supplies the pressure to the engagement device; and a case that houses the rotary electric machine, speed change mechanism, engagement device, and pump. At least the engagement device is housed in a space formed by the case, and the second hydraulic pressure control device is provided at a part of the case forming the space.

Vehicle drive device

A sealing-equipped oil pan includes a gasket and an oil pan having a bottom portion and a peripheral wall for storing oil, and a ring-shaped rim portion located at an end of the peripheral wall and provided with the gasket, and is fastened to a target device with the gasket interposed between the rim portion and the target device. The gasket has a projection projecting from a sealing surface configured to come into contact with the target device for sealing. The peripheral wall of the oil pan has a base portion projecting from the rim portion and supporting the projection of the gasket. The base portion supports the projection of the gasket to prevent the gasket from tilting with respect to the rim portion, thereby preventing protrusion of the gasket.

Sealing-equipped oil pan

A first planetary gear and a clutch are placed between a second carrier of a second planetary gear and an output shaft in the axial direction. A transmission case has a small diameter tubular portion that rotatably supports an output shaft, an annular wall portion extended radially outward from the small diameter tubular portion, and a large diameter tubular portion extended in the axial direction from the outer periphery of the annular wall portion such that the first planetary gear and the clutch are partially surrounded. A mount is fixed to a vehicle body of a vehicle so as to at least partially overlap the small diameter tubular portion, the annular wall portion, and the large diameter tubular portion as viewed in the radial direction. A parking gear of a parking lock device is coupled to the outer periphery of the second carrier.

Power transmission device

A speed change device that transmits power input to an input shaft to an output shaft while changing a speed ratio to a plurality of speeds, the speed change device including: a planetary gear mechanism including a sun gear, a ring gear, and a carrier that rotatably supports a plurality of pinion gears, each of the plurality of pinion gears meshing with at least one of the sun gear and the ring gear; and a brake including a brake hub fixed to the carrier and a friction plate fitted to an outer circumference of the brake hub, the brake being capable of holding the carrier stationary to a case.

Speed change device

In a gear pump, an outer inner wall surface of a suction port which is located on a downstream side in a rotor rotation direction, that is, a first inner wall surface, is located inward of a bottom land between internal teeth of an outer rotor, and the suction port has a shallow portion extended inward from the first inner wall surface on the downstream side in the rotor rotation direction, and a deep portion that is formed so as to be continuous with the shallow portion and that is deeper than the shallow portion. Communication between an inter-tooth chamber and the suction port is cut off with the inter-tooth chamber facing only the shallow portion.

Gear pump including an inner rotor having a plurality of teeth

A vehicle drive device having a rotating electrical machine, a speed change mechanism, and a case that accommodates the rotating electrical machine speed change mechanism. A first oil storage portion is provided so as to communicate with the speed change mechanism accommodating space. A hydraulic pump that supplies the oil in the first oil storage portion to the speed change mechanism and the rotating electrical machine. A second oil storage portion provided so as to communicate with the rotating electrical machine accommodating space. A discharge oil passage discharges the oil in the second oil storage portion to the first oil storage portion. The discharge oil passage includes a first opening that opens toward the first oil storage portion, and the first opening is provided so that its lower end is located above an oil level in the first oil storage portion during rotation of the hydraulic pump.

A vehicle drive device in which a friction engagement device, a rotary electric machine, and a speed change device are provided on a power transfer path that connects between an input member drivably coupled to an internal combustion engine and an output member drivably coupled to wheels, the elements provided in this order from the input member side.

A vehicle drive device having a case that includes a support wall portion that extends in a radial direction of the rotary electric machine at a location between the rotary electric machine and the fluid coupling in the axial direction. A rotor member and the coupling input member are coupled so as to rotate in conjunction with each other to form a power transfer member. The vehicle drive device further includes a first bearing that supports the power transfer member from a second axial direction side so as to be rotatable with respect to the support wall portion, the second axial direction side being an opposite side from the first axial direction side, and a second bearing that supports the power transfer member from the first axial direction side so as to be rotatable with respect to the support wall portion.

A vehicle driving apparatus includes a rotating electrical machine and an engagement device, which are disposed on a power transmission path linking an input member drive-coupled to an internal combustion engine and an output member drive-coupled to a wheel. The engagement device includes an engagement input coupled to the input member, an engagement output that forms a pair with the engagement input and is coupled to the rotating electrical machine, a friction member disposed between the engagement input and the engagement output, and a pressing member that presses the friction member in a pressing direction. An oil pressure chamber is formed between the pressing member and either the engagement input or the engagement output. A biasing spring biases the pressing member in the pressing direction when no oil pressure is supplied to the oil pressure chamber and is disposed on an exterior of the oil pressure chamber.

Vehicle driving apparatus

A vehicle drive device for a rotary electric machine. A case of the device includes a support wall portion that extends in a radial direction of the rotary electric machine at a location between the rotary electric machine and the fluid coupling in the axial direction. A first bearing and a second bearing that is separate from the first bearing are disposed at different positions in the radial direction from each other, the first bearing being configured to support the rotor member in the radial direction so as to be rotatable with respect to the support wall portion, and the second bearing being configured to support the coupling input member in the radial direction so as to be rotatable with respect to the support wall portion.
