The present invention provides a transmission mechanism with which a deterioration in accuracy can be suppressed and a service life can be increased by suppressing lubricant deterioration. A transmission mechanism is provided with a housing, a first rotating member which is accommodated in the housing and which is capable of rotating about a first rotating member axis, and a lubricant which is accommodated in the housing to lubricate the first rotating member, wherein: the transmission mechanism is additionally provided with a first filter member which is accommodated in the housing to filter out dust contained in the lubricant; the lubricant is agitated by means of the rotation of the first rotating member about the first rotating member axis; and the first filter member is provided in the direction in which the lubricant is caused to flow by means of the agitation from the first rotating member.

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 drive unit (HY, G) for a motor vehicle includes a housing (GG), in which a torque converter (TC) and an electric machine (EM) are accommodated. The electric machine (EM) and the torque converter (TC) are arranged directly next to each other such that the electric machine (EM) is arranged at a first face end (TC1) of the torque converter housing (TCG). An oil guide shell (LS) at least partially encompasses a section of the torque converter (TC). The oil guide shell (LS) has an L-shaped cross-section including a first section (LS1) and a second section (LS2) and is arranged in such that the first section (LS1) partially encompasses a second face end (TC2) of the torque converter housing (TCG) and the second section (LS2) partially encompasses a circumferential surface of the torque converter housing (TCG).

An axle assembly that includes a differential carrier, a bearing cap, and a lubricant reservoir. The differential carrier has a bearing support. The bearing cap is disposed on the bearing support. The lubricant reservoir is mounted on the bearing cap and is configured to capture lubricant that is splashed by the differential assembly.

Systems are provided for an axle housing comprising at least one dam. In one example, an axle housing, comprising a center portion including a cavity configured to house a differential assembly and at least one dam arranged in an arm portion that extends from the center portion and is configured to receive an axle shaft, wherein the at least one dam comprises a flow facilitating protrusion that extends from the dam panel in a direction away from the center portion.

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.

A gear unit includes a toothed wheel, a reservoir receiving lubricant for lubricating the toothed wheel, a displacement body configured to set a lubricant level in the reservoir, and an actuator configured to move the displacement body as a function of a temperature as the displacement body is wetted with the lubricant.

A vehicle driveline component with a housing, a rotary power transmission system, a lubricant and a lubrication de-aerator. The housing defines a cavity and a sump. The rotary power transmission system is received in the cavity and includes a plurality of gears that are in meshing engagement. The lubricant is received in the sump and is employed to lubricate the rotary power transmission system. The lubrication de-aerator is received in the housing and has at least one matrix of de-aeration cells that extend between an upper surface and a lower surface. Each of the de-aeration cells has a cell inlet, which is formed through the upper surface, and a cell outlet that is formed through the lower surface. Each of the de-aeration cells tapers between its cell inlet and its cell outlet.

A gearbox includes a housing including a lubricant reservoir, at least one gear system arranged in the housing, at least one lubricant delivery passage operable to direct a flow of lubricant from a lubricant reservoir onto the at least one gear system, at least one lubricant return passage operable to guide the flow of lubricant to the lubricant reservoir, and a lubricant-out sensor fluidically connected to the at least one lubricant return passage. The lubricant-out sensor is operable to detect a non-pressure based parameter of the lubricant.

A planetary gearbox for a wind power installation includes a planetary carrier having a first and second carrier cheeks, planetary gears mounted rotatably on the first and second carrier cheeks via bearing pins, respectively, an internal gear meshing with the planetary gears, with an assembly clearance being configured between a cheek external diameter of the first and second carrier cheeks and an internal diameter of the internal gear, and a planetary carrier spider configured to position the first and second carrier cheeks at a defined spacing with respect to one another. The planetary carrier spider has a radially outwardly pointing outer side which extends at a greater spaced-apart relation radially inward from a radially inner tip circle radius of an internal toothing system of the internal gear than the first and second carrier cheeks and which is arranged radially outside with respect to an internal diameter of the planetary gears.
