A vehicle drive apparatus includes a motor generator, a speed reduction mechanism connected to a rotor shaft of the motor generator, an output shaft connected to the speed reduction mechanism, an intermediate wall separating the motor generator from the speed reduction mechanism, and a bearing that is fixed to the intermediate wall and supports the rotor shaft. The motor generator, intermediate wall, speed reduction mechanism, and output shaft are disposed in this order, and a ring gear of the speed reduction mechanism is fixed. The ring gear is fixed to the intermediate wall via a ring gear flange that is positioned relative and fixed to the intermediate wall by a centering mechanism and a locking mechanism. The centering mechanism is formed by fitting a boss of the ring gear flange and the intermediate wall. The locking mechanism is disposed on an outer peripheral side relative to the centering mechanism.

Vehicle drive apparatus

A liquid pressure generating apparatus including a pump; and two one-way clutches arranged coaxially with the pump's drive shaft. Inner races of the respective two one-way clutches are integrated with each other to form a common inner race. Outer races of the respective two one-way clutches are formed independently from each other and are driven respectively by pump driving members different from each other. The common inner race includes a coupling portion coupled to the pump drive shaft and extending in the radial direction and a cylindrical body portion extending from the coupling portion in a second axial direction opposite from the first axial direction on the radially outside the pump drive shaft. The body portion includes a depression indented radially outward on an inner peripheral surface thereof. A lubricant supply portion for the depression is provided radially inside the depression.

Liquid pressure generating apparatus and driving apparatus

A carrier is implemented which is capable of reducing the number of parts and the number of bonding steps. The carrier includes a pair of holding members that hold from both sides in an axial direction L a pinion shaft supporting a pinion gear. A first holding member as one of the pair of holding members includes a coupling portion extending in the axial direction L toward a second holding member as the other holding member. The second holding member is a disc-like member, and has an external outer peripheral gear integrally formed in its outer peripheral portion. The coupling portion is bonded to a coupling bonding portion provided on a radially inner side Rof the outer peripheral gear in the second holding member.

Carrier

A vehicle motive power transmission apparatus includes: a planetary gear device; an oil pump for sucking oil present in an apparatus case; a one-way clutch that transmits normal-direction rotation output of the planetary gear device to the oil pump, but does not transmit reverse-direction rotation output of the planetary gear device to the oil pump; an oil tank which is provided in the apparatus case, and which is provided with a first introduction portion that receives oil that is splashed upward as a gear in the apparatus case rotates in a normal direction, and a second introduction portion that receives oil that is splashed upward as the gear rotates in a reverse direction; and an oil passageway that supplies the planetary gear device with oil present in the oil tank or oil sucked by the oil pump.

Lubrication of a planetary gear device

A connector fitting structure enabling easy insertion is provided. The connector fitting structure includes a case provided with a plurality of holes, a male connector having connectors fitted into the plurality of holes, respectively, and sealing elements as sealing members interposed between the holes and the connectors, respectively. Connectors each have a tapered surface. The respective tapered surfaces are shifted in position such that a tapered surface comes into contact with a sealing element, and then another tapered surface comes into contact with a sealing element.

The continuously variable belt transmission is provided with a fixed sheave and a movable sheave provided on a secondary shaft, a first hydraulic chamber that presses the movable sheave in an axial direction, a second hydraulic chamber that gives the movable sheave a pressing force acting in a direction opposite the pressing force given by the first hydraulic chamber, an oil passage connected to the second hydraulic chamber, and an oil receiver disposed along a path from the oil passage to the second hydraulic chamber. The oil receiver is attached to the secondary shaft, a bearing and a bulkhead are disposed on both sides of the oil receiver, an oil passage is provided in the secondary shaft, and a grooved portion provided in the oil receiver connects the second hydraulic chamber and the oil passage.
