The oil storage structure includes an oil pan that closes a lower opening of the transmission case and forms an oil pool in a lower space inside the transmission case, and a strainer having a suction port for oil located in the oil pool. The suction port for the oil is provided so as to face a bottom wall portion of the oil pan with a gap in between, and the bottom wall portion of the oil pan is provided with a protruding portion protruding toward the suction port, with the protruding portion being formed in a direction across the suction port as viewed from the bottom wall portion.

A gear unit includes a housing, a trough for guiding oil and reducing losses due to splashing surrounding a circumferential section of a toothing part, particularly a gear wheel, especially in the radial and axial direction, the trough including at least three parts, e.g., at least one bottom plate and two side walls, the bottom plate being screw-connected to the two side walls, the trough being fastened to the housing, the trough having an opening, particularly a channel, especially at its lowest surface area, e.g., particularly at the surface area having the greatest radial distance, in particular, during rotational movement of the gear wheel, oil being conveyed from the oil pan of the gear unit through the opening between the trough and gear wheel, especially to a position higher than the level of the oil pan, the bottom plate and the side walls being stamped bent parts.

A drive assembly for a kart, and a kart including the assembly is disclosed. The assembly includes an electric motor including an output shaft; an assembly housing surrounding the motor, the housing defining an aperture; an intermediate shaft rotatably disposed within the assembly housing; a driving gear removably disposed on the output shaft within the housing; a reduction gear removably disposed on the intermediate shaft within the housing; and a panel removably connected to the housing for selectively covering the aperture, the driving gear and the reduction gear being removable from the motor and the housing via the aperture when the panel is removed from the housing, the panel, the driving gear, and the reduction gear being disposed above a maximum level of transmission oil contained within the housing when the motor is not operating. A method of changing a kart transmission ratio is also disclosed.

A drain plug for an oil pan coupled to a plug mounting hole formed at one side of a lower portion of the oil pan, the drain plug may include a head portion configured to be formed at one end portion of the drain plug, and a screw portion configured to extend from the head portion and be screw-coupled to the plug mounting hole of the oil pan.

A lubrication system for an in-wheel motor powertrain is proposed. The system includes a housing having a motor and supporting a wheel, and having a space therein; an input gear and an output gear provided in the housing; two intermediate gears each provided with a first gear meshed with the input gear, and a second gear meshed with the output gear and having a pitch circle diameter different from that of the first gear, the first and second gears being integrally and concentrically coupled together; a pump gear meshed with the input gear; a bearing plate rotatably supporting the input gear, the output gear, and the intermediate gears; a cover plate configured to provide a part of a lubrication pump driven by the pump gear; and a first oil supply part provided by the cover plate and a mid-plate to lubricate the output gear and the intermediate gears.

A work equipment transmission includes a gear, a gearbox, and a baffle. The gearbox housing contains the gear within an internal cavity that defines a sump and is defined by a first housing body having a first baffle-retaining surface and an outlet opening and a second housing body having a second baffle-retaining surface. The baffle has a shroud wall defining a peripheral lip for engagement with the first baffle-retaining surface, an annular collar having an annular collar lip for engagement with the second baffle-retaining surface, and an end wall. The baffle is mounted within the gearbox housing, the end wall extending proximate the gear and the shroud wall extending at least partially around the gear. The baffle is mounted by a clamping force between the first housing body and the second housing body.

An axle assembly including a disconnect assembly and an integrated fluid flow system. The disconnect assembly including an axially movable clutch member in selective engagement with at least one shaft to permit a rotation thereof. The fluid flow system includes a fluid flow member and a plurality of fluid passageways to permit a flow of a fluid (e.g. a lubricant) from a fluid source (e.g. a fluid sump of the axle assembly) to various components disposed within a carrier housing of the axle assembly and a return of the fluid back to the fluid source.
