A method of assembling an epicyclic gear train includes providing a unitary carrier that includes spaced apart walls and circumferentially spaced mounts interconnecting the walls, spaced apart apertures provided between the mounts at an outer circumference of the carrier, gear pockets provided between the walls and mounts extending to the apertures, and a central opening in at least one of the walls, inserting an intermediate gear through the central opening and moving the intermediate gear radially into the gear pocket to extend through the aperture, inserting a baffle into the carrier, and inserting a sun gear through the central opening to intermesh with the intermediate gear.

A vehicle transfer case is provided having a housing, a primary shaft rotatably mounted within the housing, a secondary shaft selectively driven by the primary shaft, a hub torsionally fixed with the primary shaft, a clutch housing selectively torsionally connected with the hub via a friction pack, an engagement wheel torsionally fixed with respect to the clutch housing and torsionally connected with the secondary shaft via a flexible torsional force member, the friction pack, upon engagement, causing the clutch housing to be selectively connected with the hub, a reservoir system fixed with respect to the housing capturing lubricant energized by result of the operation of the flexible torsional member, the reservoir system delivering splashed lubricant to a reservoir system, and an Archimedes' screw pump delivering lubricant from a sump adjacent to the secondary shaft to the secondary reservoir system.

A cooling arrangement to cool the rollers of a toroidal CVT is described herein. The cooling arrangement includes nozzles so configured and sized as to project cooling fluid onto the edge and onto the opposite top and bottom surfaces of the roller.

A gear system is disclosed. The gear system has a structure in which oil churned by a gear is dispensed to at least one of a hollow space or a bearing, thereby effectively lubricating components. For example, the gear system includes a first shaft comprising a hollow space, a first gear arranged at an outer circumference of the first shaft, a second gear externally engaged with the first gear, a bearing arranged at the outer circumference of the first shaft, a housing surrounding the first gear and the second gear, and an oil guide plate disposed between the first shaft and the housing to dispense oil churned by the second gear to the hollow space of the first shaft and the bearing coupled to the first shaft.

One or more guide members for use within a drive unit assembly of a vehicle. The one or more guide members have a body portion with an outer peripheral surface, a first end portion, a second end portion, and an intermediate portion interposed between the first end portion and second end portion. The intermediate portion of the one or more guide members have a first angularly bent portion defining a first extending portion and a second extending portion extending outward therefrom. The body portion of the one or more guide members have one or more shaft receiving portions therein.

A transmission for a motor vehicle includes a housing and a gear set. An oil drainage channel is formed by the housing and/or by an element connected to the housing and is arranged spatially underneath the gear set. The oil drainage channel includes at least one gear set-side inlet port, a closed underside, and an oil sump-side outlet port at one end of the oil drainage channel, which are designed and arranged in such that oil from the gear set enters the oil drainage channel through the at least one inlet port and is guided along the closed underside to the outlet port. A suction port of a hydraulic unit of the transmission is arranged in the oil sump spatially underneath the closed underside of the oil drainage channel and axially offset with respect to the outlet port.

A powertrain arrangement for a transverse mounted motor for an electric powered automotive passenger vehicle including opposing wheel shafts for powering two parallel mounted wheels, the shafts rotating about a first axis, the shafts having at least one end torsionally connected with a differential, an electrical rotor torsionally connected with the wheel shafts via a planetary gear train, an electrical stator surrounding the rotor, a casing supporting the rotor and the wheel shafts, the casing encompassing the stator, the casing having a floor forming a lubricant reservoir, and a baffle located in the lubricant reservoir. The baffle forming a wall with a portal allowing flow through the formed wall, and wherein an increase of fluid pressure throttles flow through the formed wall.

Transmission having a housing composed of at least one first and second component for accommodating transmission components, wherein one of the components has at least one bore for the supply of oil, wherein one component has a bore, and a second component has a guide device for oil, which both open in the direction of a sealing surface between the first and second components, wherein the guide device engages axially around a sleeve which is under spring preload, or a sleeve which is under spring preload engages axially around the guide device.

A continuously variable transmission includes a case member including an outer surface on the side where a torque converter is disposed and an inner surface on the side where a driving force transmission mechanism is disposed. The case member includes a supporting hole by which a bearing that supports a third shaft is supported, a supporting hole by which a bearing that supports a fourth shaft is supported, and an oil path through which an lubricant, to be supplied to the bearing and the bearing, is supplied. The oil path protrudes from the outer surface from the case member and has a straight line shape connecting between the supporting hole and the supporting hole. Thus, components can be appropriately lubricated even when it is difficult to provide lubrication pipes.

A lubrication structure of a power transmission device, includes a housing including a bottom space to store lubricating fluid in which a rotating body is immersed to be lubricated, a partition dividing the bottom space into a first space in which a rotating body is provided and a second space opening to the first space, a tubular duct including a projection duct projecting in a projection direction from an end of the first space to the second space such that the first space and the second space communicate with each other via the tubular duct, and a strainer provided in the second space and including a suction inlet through which the strainer is configured to suction the lubricating fluid stored in the bottom space, the suction inlet being located between the end of the first space and a tip end of the projection duct in the projection direction.
