A power transmission device includes a pinion gear having a large pinion gear and a small pinion gear, a carrier that supports the pinion gear, a ring gear that engages with the small pinion gear, an oil supply unit positioned above a horizontal line that passes through a revolution center of the pinion gear, and a downstream side wall part facing a gear surface of the large pinion gear. The downstream side wall part is arranged to be adjacent to the oil supply unit further downstream in a revolution direction of the pinion gear than the oil supply unit when viewed from an axial direction.

A continuously variable transmission for a vehicle includes a drive clutch, a driven clutch operably coupled to the drive clutch, and a belt extending between the drive and driven clutches. The continuously variable transmission also includes an inner cover and an outer cover removably coupled to the inner cover. At least one of the inner and outer covers includes an air inlet for providing cooling air to the drive and driven clutches and the belt.

A power transmission device includes a bearing, a differential mechanism, a case that houses the differential mechanism, a pinion gear supported by the case, a wall part that overlaps the case in an axial direction, a plate that is provided between the wall part and the case in the axial direction, and that supports the case with the bearing being interposed, and a parking pawl that is rotatably fixed to the plate in a position that overlaps the plate in the axial direction.

A power transmission device includes a box, a case disposed in the box, a differential mechanism housed in the case, and a planetary gear mechanism disposed in the box and supported by the case. The planetary gear mechanism includes a sun gear and a pinion gear that engages with the sun gear. The box has a shelf part above a horizontal line that passes through a revolution center of the pinion gear. The shelf part is arranged at a position that does not overlap the sun gear when viewed from radially above.

The present invention teaches a gearbox expansion cap that allows a gearbox unit to breathe to atmosphere while preventing the ingress of water or other materials into the gearbox or gearbox oil. According to a first preferred embodiment, the expansion cap of the present invention includes a pressure relief plug to control gearbox pressures. Additionally, the present invention teaches air channels enclosed within a gearbox casting which mate with air channels provided within the expansion cap to channel air from the expansion cap into the atmosphere.

A end-piece having a hollow tubular body having a longitudinal main axis X and provided with a plurality of longitudinal slots extending from an open end of the end-piece and delimiting a plurality of snap-fitting tabs, each provided with a snap-fitting leg delimited axially by a radial shoulder and extending axially by a guide ridge towards said free end, the guide ridge having a top corresponding to a maximum snap-fitting force linked to the crossing of said top. At least first and second tabs defining respectively first and second tops, the tops are axially shifted relative to each other.

A continuously variable transmission housing comprising an inner cover; and an outer cover connectable to the inner cover to provide the housing having an interior chamber defined therein. The housing outer cover comprises a primary clutch dome integrally formed within the housing outer cover and defining a primary clutch alcove within the interior chamber of the housing and an air duct integrally formed within the housing outer cover and extending from the primary clutch dome at a proximal end. The air duct structured and operable to direct air circulating within the interior chamber from the primary clutch alcove to an area of the interior chamber that is at an opposite end of the interior chamber from the primary clutch alcove.
