A driving device including a drive shaft and a first engaging member. The drive shaft rotates around a first axis. The first engaging member is disposed on the first axis to rotate integrally with the drive shaft. The power transmission mechanism includes a second engaging member, a propeller shaft, a piston, and a reduction gear. The second engaging member is disposed on the first axis engageable with/disengageable from the first engaging member. The propeller shaft is rotatable integrally with the second engaging member around the first axis. The piston reciprocates the second engaging member between a first position and a second position along a direction of the first axis. The reduction gear is joined to the other end side of the propeller shaft to decelerate the rotation of the propeller shaft. The reduction gear causes an output shaft joined to an object to rotate around a second axis.

A driving force transmission device of a vehicle includes: a main body; a carrying up gear; a drive shaft; and a blocking member. A gear that transmits a driving force to the vehicle is housed in the main body. The carrying up gear carries up a lubricating oil stored in the main body. The drive shaft has, in the shaft, a lubricating oil storage space into which the carried up lubricating oil is introduced and a lubricating oil discharge hole through which the lubricating oil in the lubricating oil storage space is supplied to a bearing unit. The blocking member blocks the lubricating oil discharge hole in accordance with a rotational speed of the drive shaft.

The present invention describes an accessory gearbox with a shaft incorporated into a casing and connectable at least in one lateral end area to an accessory unit, with the shaft at least in the lateral end area being designed as a hollow shaft having an inner toothing. To lubricate the inner toothing in the area of the casing at least one baffle device is provided which is designed for guiding hydraulic fluid present in the area of the casing, under the effect of gravity, in the direction of at least one opening provided in the shaft.

A lubricating liquid manifold for a crankpin of an epicyclic gear train. The epicyclic gear train is lubricated by a lubrication system conveying a first flow of a lubricating liquid towards the manifold and a second flow of the lubricating liquid towards a member to be lubricated. The manifold comprises a hollow body provided with an inlet port intended to receive the first flow and an outlet port designed such that the first flow is conveyed towards a guide device connected to the crankpin. The manifold comprises a barrier comprising a shoulder connected to the body and a deflector protruding radially outwards from the body so as to form, with the shoulder, a diversion space for diverting the second flow and preventing it from penetrating into the manifold.

A hybrid vehicle drive device includes a power transmission mechanism including a transmission coupled to an engine output shaft, a clutch coupled to a transmission output shaft, a first gear coupled to a clutch output shaft, a final reduction gear that constantly meshes with the first gear, a drive shaft coupled to the final reduction gear, a first rotary element coupled to an electric motor, and a second rotary element that meshes with the final reduction gear and rotates in accordance with the rotation of the rotary element. The power transmission mechanism is disposed so that, when viewed from the rotational axis direction of each gear, a line that connects the rotational axis of the first rotary element and the rotational axis of the second rotary element is inclined to the first gear side in relation to the vertical direction of the vehicle when mounted to a vehicle.

A baffle for use with one or both bevel gears in a transmission system is disclosed that can include a rim having a frustoconical shape, multiple pockets on an inner side of the rim configured to collect lubricant, and multiple slots extending through the rim with each slot of the multiple slots being adjacent to a corresponding pocket of the multiple pockets and configured to allow lubricant to flow through the rim. A transmission system is also disclosed that can include a first gear, a second gear, and a baffle surrounding gear teeth of the first or second gear. The baffle has a plurality of pockets adjacent to the gear teeth and a plurality of slots adjacent to the plurality of pockets with the plurality of slots extending through the baffle.

A gear assembly for an aeronautical engine includes a first gear disposed at a centerline axis of the gear assembly, a second gear coupled to the first gear in adjacent radial arrangement to form a first mesh between the first gear and the second gear, a static portion coupled to the second gear in adjacent circumferential arrangement, the static portion defining a pocket, and a spraybar disposed within the static portion such that a supply opening of the spraybar is directed at the first mesh between the first gear and the second gear. The supply opening provides a flow of lubricant to the first mesh between the first gear and the second gear and at least a portion of the flow of lubricant is collected by the pocket. The flow of lubricant is continuously released from the pocket to the gear system.

An all-wheel drive vehicle driveline that includes a housing assembly with a housing structure and a cover. In one form, components of the driveline can be assembled to the housing structure and cover in such a way that an intermediate shaft, which is assembled to the cover, and an input shaft, which can be rotatably mounted to the housing structure, can be slidably engaged to one another. In another form, the cover defines a reservoir that is configured to feed fluid to a pump that is mounted to the cover.

One aspect of a motor unit of the present invention is a drive apparatus including a motor that has a motor shaft extending in an axial direction, a transmission mechanism that is connected on one side in the axial direction of the motor shaft, a lock mechanism that restricts driving of the transmission mechanism, a housing that houses the motor, the transmission mechanism, and the lock mechanism, an oil that is stored in the housing, and an oil passage that circulates the oil. The housing includes a motor room that houses the motor, a gear room that houses the transmission mechanism and the lock mechanism, and a partition that is provided between the motor room and the gear room. The oil passage includes a pump that pumps the oil in the oil passage, a first feed flow passage that feeds the oil to the motor, and a second feed flow passage that feeds the oil to the lock mechanism.
