A shifting device for a motor vehicle transmission has a first coupling component, a second coupling component rotatable about a transmission axis (A), an inner friction ring which has a conical surface on a radially outer face, an outer friction ring which has a conical surface on a radially inner face, and an intermediate friction ring having a C-shaped ring cross section, including a friction cone connected to the second coupling component for joint rotation with and for axial displacement with respect to the second coupling component, while the inner friction ring and the outer friction ring are connected to the first coupling component for joint rotation with and for axial displacement with respect to the first coupling component. The friction cone extends between the conical surfaces of the inner friction ring and outer friction ring.

An engine power unit for a vehicle has a crankcase made up of tow left and right crankcase members, and a lubricant feed pump disposed in one crankcase member in such a fashion that one side surface of pump rotors of the feed pump lies on the mating surface of the crankcase members. The feed pump is mounted on one end of the shaft of the feed pump while a drive gear for rotating the shaft is disposed on the opposite end of the shaft. A lubricant oil filter to which oil is delivered from the feed pump is disposed on the other crankcase member. Thus, the structure for supplying lubricating oil is simplified, and the power unit is reduced in size in its entirety.

A gear device includes a first gear, a second gear, and a third gear. The second gear is offset eccentrically when the first gear is rotated. The third gear is rotated at a speed slower than a rotation speed of the first gear when the second gear is offset eccentrically. The stopper plate is engaged with the second gear through a fitting structure thereby restricting rotational movement of the second gear while permitting linear movement of the second gear. One of the second gear and the stopper plate includes an engagement claw. The other one of the second gear and the stopper plate includes a recess engaged with the engagement claw. The engagement claw includes a grease sump that holds grease applied between the recess and the engagement claw.

A transmission shift fork comprising: an arch-shaped portion, where a pair of lobes are radially and inwardly projecting from an inner surface of the arch-shaped portion directing oil to a sleeve engagement region of a clutch.

A lubrication system for a clutch. Where the system comprises: a pump; one or more conduits connected to the pump; and at least one body coupled to a shift arm for engaging a sleeve, where the at least one body comprises an inlet connected to a conduit from the one or more conduits, at least one outlet, and an internal passage being in fluid communication between the inlet and the at least one outlet, where lubricant passing through the conduit exits at the at least one outlet to lubricate the body and the sleeve.

A transmission device includes a transmission unit housed inside a transmission case with an oil storing part at a bottom part of the transmission case. As viewed in a projection plane orthogonal to a rotation axis of the transmission unit, an oil capturing part is arranged in a semicircle part of an outer circumferential wall of the transmission case. The semicircle part starts at a deepest part of the oil storing part and is positioned on a front side in a normal direction of a carrier.

A lubrication system for a vehicle includes a heat exchanger having a lubricant inlet and a lubricant outlet with the lubricant outlet having a first outlet branch and a second outlet branch. The lubrication system also includes a stator lubrication circuit, a rotor lubrication circuit, and a gearbox lubrication circuit fluidly connected between the lubricant inlet and the first outlet branch. The gearbox, stator, and rotor lubrication circuits are connected fluidly in parallel with each other. The system also includes a park actuator assembly having a parking pawl configured to move between a parking position and a release position allowing movement of the drivetrain gear and a park actuated valve configured to move into a first position blocking lubricant flow through the second outlet branch when in the parking position and into a second position allowing lubricant flow through the second outlet branch when in the release position.
