A power transmission apparatus is used in a vehicle and mounted on a vehicle member via a mount. The power transmission apparatus includes a case. The case includes a motor provided inside the case. The case includes a mount fastening portion for fastening the mount with a plurality of bolts. The mount fastening portion has a plurality of bolt tightening holes. The plurality of bolt tightening holes are provided so that the plurality of bolts are tightened into the plurality of bolt tightening holes. The bolt tightening holes have axial directions parallel to each other. A space isolated from an inside of the case is formed by a wall of the case in a region connecting two adjacent bolt tightening holes when the mount fastening portion is viewed in the axial directions of the plurality of bolt tightening holes.

Power transmission apparatus

In a vehicle motor unit comprising: a motor; and a storage housing storing the motor, the motor including a rotor arranged rotatably around a rotation axis, a stator disposed on an outer circumferential side of the rotor, and a high voltage portion disposed on the stator, an outer circumferential surface of the stator is configured to surface contact with a part of a wall surface of the storage housing receiving a larger collision load at the time of a vehicle collision as compared to the other parts.

Vehicle motor unit

An electric vehicle comprises: an electric drive unit including an electric motor used as a drive power source, a transaxle including a differential device and coupled to a motor shaft of the electric motor in a power transmittable manner on one end side of the electric motor in a direction of a motor centerline to transmit an output of the electric motor through the differential device to a pair of drive shafts, and a case housing the electric motor and the transaxle. The case includes a first end surface portion located on the other end side of the electric motor in the motor centerline direction and rotatably supporting the motor shaft, and an accessory component of the vehicle is attached to an outside surface of the first end surface portion.

Electric vehicle

A lubricating device of a gear apparatus for a vehicle lubricates a low-rotation-side gear and a high-rotation-side gear meshing with the low-rotation-side gear. The lubricating device comprises a first tooth surface lubricating oil supply part configured to supply a lubricating oil directly to a tooth surface position located more upstream of a rotating direction of the low-rotation-side gear than a meshing position of the low-rotation-side gear with the high-rotation-side gear so as to spray some of the lubricating oil from the tooth surface position toward a tooth surface of the high-rotation-side gear, and an in-shaft lubricating oil supply part configured to supply the lubricating oil into a shaft of the high-rotation-side gear.

Lubricating device of gear apparatus for vehicle

A hybrid vehicle comprises an engine; a first rotary machine configured to drive the hybrid vehicle; a power transmission system configured to transmit drive force from the engine and the first rotary machine via an output unit to driven wheels; a first oil pump configured to be mechanically rotary-driven along with rotation of the output unit; a second oil pump configured to be rotary-driven by a rotary drive source that is different from the output unit; a first supply passage connected to a discharge side of the first oil pump, and the first supply passage configured to supply lubricating oil at least to the first rotary machine; a second supply passage connected to a discharge side of the second oil pump, and the second supply passage configured to supply lubricating oil at least to the first rotary machine; and an oil cooler provided to the second supply passage.

Hybrid vehicle

Inside a casing, a gear chamber that accommodates a gear mechanism of a power transmission apparatus and also stores lubricating oil for lubricating the gear mechanism therein is partitioned across a first coupled part where case members are coupled to each other, and a road clearance of the first coupled part is set to be the lowest on a bottom surface of the casing and a cylinder block of an engine. A lower cover is provided with a projection upwardly projecting at a predetermined part thereof, the predetermined part being located apart from a position immediately below the first coupled part on the bottom surface, and a distance between the projection of the lower cover and the bottom surface is set to be smaller than a distance between the lower cover and the first coupled part.

Protective structure for power transmission apparatus

During the travel of a vehicle, the oil level of lubricating oil is lowered due to the suction by at least a first oil pump and the scraping-up by the rotation of a differential ring gear and so on. In particular, until the oil level becomes equal to or lower than an upper end of a first partition wall, the oil level is lowered due to both the suction by the first oil pump and the scraping-up by the rotation of the differential ring gear and so on, and therefore, a region, that is immersed in the lubricating oil, of the differential device rapidly becomes smaller. Since a suction port of the first oil pump is disposed in a second oil storage portion, the oil level in the second oil storage portion during the travel of the vehicle can be adjusted independently of that in a first oil storage portion.

Lubricating device of power transmission device for vehicle

A lubricating apparatus for a vehicle, comprises a first oil pump and a second oil pump, and a first supply passage connected to a discharge side of the first oil pump on which the lubricating oil is discharged so as to supply the lubricating oil discharged from the first oil pump to lubricated parts of the power transmission system, a second supply passage that is provided independently from the first supply passage and is connected to a discharge side of the second oil pump on which the lubricating oil is discharged so as to supply the lubricating oil discharged from the second oil pump to the lubricated parts of the power transmission system.

Lubricating apparatus of vehicle

Control apparatus for hybrid vehicle drive system including: first differential mechanism provided with a rotary element connected to engine and rotary element connected to a first electric motor; a second differential mechanism provided with a rotary element connected to second electric motor and a rotary element connected to output rotary member; first clutch configured to selectively connect rotary element of first differential mechanism connected to engine or first electric motor, to rotary element of second differential mechanism connected to output rotary member; manually operated shifting device; and parking lock mechanism provided with parking lock gear fixed directly or indirectly to output rotary member and rotary motion which is prevented when shifting device is placed in parking position, control apparatus including parking lock control portion configured to release parking lock gear for permitting rotary motion of parking lock gear while first clutch is placed in its engaged state.

Control apparatus for a hybrid vehicle drive system

An oil strainer is provided with a tube () for allowing oil to flow therethrough, a mesh () mounted to one end () of the tube (), a protector () connected to said end () of the tube () so as to cover the mesh (), and a bracket () for fixing the tube () to a surrounding member mounted around the oil strainer (). The bracket () has a staking section () for staking the protector () and the tube () together. The above structure enhances productivity of the oil strainer and reduces costs of the oil strainer.

Oil strainer

A hybrid transaxlethat is a transmission is provided with a junction surfacethat contacts a junction surface of an internal combustion engine. A bolt span portionof the junction surfaceis provided with a protrusion portionthat elastically deforms so that the internal combustion engine-side junction surface and the hybrid transaxle-side junction surfaceclosely contact each other.
