A transfer case pump includes an oil pump, a cover assembly, and a torque transfer mechanism. The oil pump has a pump shaft, and is configured to pressurize a lubricant in response to a rotation of the pump shaft. The pump shaft rotates around a pump axis. The pump axis is parallel to a rear axis of a rear shaft. The pump axis is offset from the rear axis. The cover assembly has a channel configured to transfer the lubricant from the oil pump to the rear shaft. The cover assembly extends around the rear shaft and around the pump shaft. The torque transfer mechanism is configured to transfer a torque from the rear shaft to the pump shaft.

A hydrodynamic torque converter (1) with a pump wheel (3) and with a turbine wheel (4), and with a torsion damper (8) and with an intermediate space (12) located between the turbine wheel (4) and the torsion damper (8), and with a torus formed by the pump wheel (3) and the turbine wheel (4) for hydraulic fluid. A flow-guiding wall (14) is provided, which deflects a radially outward flow of hydraulic fluid coming from the torus, back radially inward to the intermediate space (12).

The invention is concerned with an oil consumer system having at least one rotating component and at least one oil supply from an oil tank, wherein the oil consumer system has an oil return to a first tank and an oil supply via at least one second tank.

A hybrid vehicle includes: a crankcase having a main chamber formed in a case body and accommodating at least a crankshaft, an input shaft, an output shaft, and a gear train, the crankcase further having a subsidiary chamber formed between the case body and a cover and accommodating at least a main clutch; a rotary member disposed in the subsidiary chamber so as to be capable of power transmission to the input shaft; and a power transmission member that transmits drive power from a drive motor to the rotary member.

Lubricant consumer system comprising at least one lubricant consumer, at least one rotating component, wherein fluid lubricant can be conveyed via the rotating component, and a lubricant distributor system, wherein the lubricant distributor system has at least two lubricant tanks, namely a first lubricant tank and at least one second lubricant tank, and a lubricant channel, wherein the two lubricant tanks are fluidically connected to one another and to the lubricant consumer via the lubricant channel, wherein one of the two lubricant tanks is designed and arranged in such a way that, in a horizontal position of the lubricant consumer system, it receives the fluid lubricant of the rotating component and supplies both the other lubricant tank and the lubricant consumer with lubricant via the lubricant channel, and wherein the other lubricant tank is designed and arranged in such a way that, in an inclined position of the lubricant consumer unit, the lubricant consumer is supplied with lubricant from at least the other lubricant tank.

A straddle vehicle includes: a prime mover; a hydraulically actuated main clutch disposed in a power transmission route between the prime mover and a drive wheel; an oil control valve unit that controls flow of a hydraulic oil supplied to the main clutch; and a power unit case including a case body and a cover removably mounted on the case body, the power unit case accommodating at least the main clutch. The oil control valve unit is secured to the case body.

A hybrid module for a hybrid vehicle is disclosed. The hybrid module has two clutches located radially inward of an electric motor, and in their own respective fluid chamber. Fluid from one chamber can cool one of the clutches. Then the fluid can travel axially to the other chamber to cool the other clutch. The hybrid module can include a wall assembly between the two clutches, separating the fluid chambers. After the fluid cools both clutches, the fluid is directed to the wall assembly, and passes through two walls, radially outwardly, to spray onto the electric motor to cool the motor.

A work vehicle includes a drive axle assembly having an axle housing with an input opening and output openings in communication with an interior cavity. A gear assembly is disposed in the interior cavity of the axle housing, with the gear assembly having an input shaft extending through the input opening and coupled for co-rotation with a drive shaft. A park brake assembly is integrated with the drive axle assembly and is disposed within the axle housing. The park brake assembly imparts a brake force to arrest rotation of the input shaft, with the park brake assembly including a brake pack and a piston disposed about the input opening of the axle housing and with the piston configured to move relative to and act on the brake pack. A Belleville spring arrangement is also disposed about the input opening of the axle housing and acts on the piston to engage or release the park brake.

A powertrain-cooling system of a hybrid vehicle may include an electric oil pump, a pressure control valve, which includes an input port receiving fluid discharged from the electric oil pump, an output port outputting the fluid to a transmission while adjusting the pressure of the fluid, and a drain port discharging a portion of the fluid in accordance with adjustment of the pressure of the fluid, a first motor cooling path connecting the drain port of the pressure control valve to a first motor forming a hybrid powertrain, and a controller electrically connected to the electric oil pump and configured for controlling the electric oil pump to cool the transmission and the first motor.

Methods and systems for a vehicle transmission are provided. A transmission system includes, in one example, an intermediate shaft rotationally coupled to an input shaft and an output shaft, wherein the input shaft is configured to receive rotational input from an electric machine. The system further includes a first gear coupled to the intermediate shaft, and a plurality of clutches coupled to the input shaft and the output shaft and configured to in a first mode, transfer power directly between a second gear coupled to the input shaft, the first gear, and a third gear coupled to the output shaft, and in a second mode, transfer power indirectly between the second gear, the first gear, and/or the third gear.
