In a vehicle drive device, a case cover includes a cylindrical wall portion formed circumferentially in an outside space of a first rotating shaft and projecting toward the case parallel to an axial direction of the first rotating shaft, an oil pump includes a pump cover arranged in a space radially inside the wall portion and a pump chamber formed in a space radially inside the wall portion by the case cover including the wall portion and the pump cover to house the pump gear, and the wall portion includes a support portion disposed on the other axial end side of the first rotating shaft relative to the pump cover, having a bearing fitted thereto, and rotatably supporting a second rotating shaft via the bearing.

Vehicle drive device

Since one end of a spring is received by a planar portion of a spring seat provided on any one of an outer plate and an inner plate, it is possible to support the spring with a planar member without machining a bottom wall face of the outer plate into a planar shape. Since the spring seat has seat guide portions that contact the outer plate, it is possible to suppress the fluctuation of the spring seat and the fluctuation of the spring by the seat guide portions, so it is possible to reliably prevent interference of the spring with its peripheral portion. Therefore, a load on the spring is reduced, so it is possible to improve the durability of a one-way clutch.

One-way clutch

A hybrid vehicle uses a first motor, a second motor and an engine as driving force sources and includes a gear transmission mechanism and an oil supply mechanism. The gear transmission mechanism transmits torque, output from the first motor, to a drive shaft side. The oil supply mechanism is driven by power other than power of the engine to supply oil to the gear transmission mechanism. When the hybrid vehicle is caused to travel by using the torque output from at least the first motor in a state where operation of the engine is stopped, and when an estimated amount of oil that is supplied from the oil supply mechanism to the gear transmission mechanism is smaller than or equal to a predetermined amount, an electronic control unit limits an operation state of the first motor such that load on the gear transmission mechanism decreases.

Hybrid vehicle

The present invention is aimed to provide a carrier assembly which can be made small in size while securing a sufficient fixing strength between a first carrier plate and a second carrier plate. The second carrier plate () has a plurality of connection elements () bent toward the first carrier plate () to weld and fix the outwardly projected end portions () of the connection elements with the outwardly projected end portion of the first carrier plate () by electron beam welding. The connection elements each have a base portions () formed with a notch (). The notch () thus formed makes a gap S between the base portion of the connection element and the corner portion () of the pinion gear.

Carrier assembly for supporting pinion gears

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.

Fastening structure of power unit

An injection apparatus includes a gate for injecting a filler to a gap between an inner wall of a slot and a permanent magnet. A plurality of gates are provided for one slot. An IPM rotor with improved NV characteristics, and method and apparatus for manufacturing such an IPM rotor can be provided by such a structure.

IPM rotor and IPM rotor manufacturing method

A planetary gear set includes a sun gear; pinions that are positioned around the sun gear and that mesh with the sun gear; and a ring gear that is positioned on the outer side of the pinions and that meshes with the pinions. Each pinion has a plurality of teeth on the outer surface thereof. Each tooth has a first tooth surface and a second tooth surface on opposite sides of the tooth, which can contact tooth surfaces of the sun gear and the ring gear. The deviation of the first tooth surface from the corresponding reference surface differs from the deviation of the second tooth surface from the corresponding reference surface.

A transaxle includes a case having an opening, a second rotating electric machine stored in the opening of the case and having a stator, a rear planetary gear stored in the transaxle case and connected to the second rotating electric machine, a transaxle rear cover sealing the opening and a bolt fixing the second rotating electric machine to the transaxle case. The stator has first and second thrust end faces defining an axial length thereof. The first thrust end face is pressed against an inner surface of the case.

Driving device with rotating electric machine

A composite gear, wherein an external gear and a rotation Support surface are formed on the outer peripheral surface thereof and a first internal gear and a second internal gear are formed on the inner peripheral surface thereof at a predetermined interval in the rotating axis direction. A chuck portion is formed on the inner peripheral surface between the first terminal gear and the second internal gear, and the inner diameter of the chuck portion is smaller than at least one of the diameter of the tip of the first internal gear and the diameter of the tip of the second internal gear.
