The electric motor may be disposed within the housing adjacent the drainage channels and a torque converter. The baffle may be disposed within the housing upon a housing inner surface, and may define an opening to the first and second drainage channels. The baffle may include a baffle flange sized for positioning adjacent the torque converter to minimize contact of oil within the housing to the torque converter. The housing may define first and second partition walls each partially extending over one of the first and second drainage channels. The baffle may further include first and second seal features each disposed at one of two baffle ends.

A transmission for a vehicle propulsion system includes a transmission housing defining a sump volume and valve body side cover volume separated by a side wall from the sump volume, a valve operable to selectively connect the valve body side cover volume with the sump volume through a fluid flow passage, a source of selectively pressurizable fluid, and an orifice connecting the source of selectively pressurizable fluid to the fluid flow passage.

A transfer device includes a drive gear, a driven gear arranged at a lower position than the drive gear, and a housing space storing gears, wherein a lubricating oil is reserved in a lower part of the housing space, wherein first and second lubricating oil reservoir spaces reserving the lubricating oil respectively adjacent to the housing space are partitioned from the housing space by first and second partition walls, wherein communication holes communicating in a state of restricting the flow to the housing space are respectively provided on the first and the second partition walls, wherein the first partition wall is provided at a lower position than a predetermined oil level and the second partition wall is provided at a higher position than the predetermined oil level.

An axle assembly having a dam module. The dam module may include a dam, an upper brace, and a lower brace. The dam may be at least partially disposed in an arm portion of a housing of the axle assembly. The upper brace and the lower brace may be disposed proximate the dam. The upper brace may transport lubricant to the dam.

An electric drive arrangement for a vehicle includes a housing. The electric drive arrangement includes an electric machine with a stator connected to the housing and a rotor with a rotor shaft rotatably supported in the housing. The electric drive arrangement includes a transmission to transmit a rotary movement from the rotor shaft to drive a driveline of the vehicle. The electric drive arrangement includes a hydraulic circuit for circulating a fluid to cool and lubricate the electric machine and the transmission.

Provide is a power transmission device lubricating structure capable of preventing air from being mixed with a lubricating fluid while suppressing a resistance applied from the lubricating fluid to a rotation body in a casing. A lubricating structure includes a strainer which includes a suction port and partition members which divide an inner space of a transmission casing. The partition members define a differential room accommodating a final driven gear and a strainer room accommodating the strainer and communicating with the differential room at an upper portion thereof.

A marine propulsion device includes a first gear, a second gear, a third gear, a case, a partition wall, and a first flow path. The case includes an internal space in which the first gear, the second gear, and the third gear are located. The partition wall is located between the second gear and the third gear in the internal space. The partition wall partitions the internal space into a first space and a second space. The second gear is located in the first space. The third gear is located in the second space. The first flow path communicates the first space with the second space. The first flow path is located on a same side as the first gear with respect to a center line of the second gear and the third gear.

A unit includes a housing configured to accommodate a gear connected to a motor, and a cover having a portion sandwiched between the gear and the motor, wherein a catch guide is provided in the housing, the catch guide has an opening that opens toward the gear, and the catch guide has a portion that overlaps a radial side surface of the cover when viewed in a radial direction.

Provided is a flow path structure of a power transmission device which is capable of removing gas from a lubricating fluid guided to a fluid reservoir while suppressing an increase in a size of the entire power transmission device. A gasket (63) has an extending portion which extends toward an inside of a transmission case (31). A flow path (70) which extends from an upper portion to a lower portion and guides lubricating oil discharged from a discharge mechanism (64) to an oil reservoir is formed inside the transmission case (31) using the extending portion. The discharge mechanism (64) discharges the lubricating oil toward an inner surface of the flow path (70).

A lubrication and hydraulic actuation system for a transfer case (120) includes a pump (220), a pump sump (210) formed in the transfer case (120), and having an opening (430) in communication with an interior of the transfer case (120), and a fluid retention element (510, 710). The fluid retention element (510, 710) is disposed in the opening (430) of the pump sump (210) and has at least one baffle structure (550) to allow fluids to enter the pump sump (210) through the fluid retention element (510, 710) and restrain fluids from exiting the pump sump (210) through the fluid retention element (510, 710).
