The planetary gear also includes a carrier that is rotatably coupled to the plurality of helical gears and transfers rotational forces to the output drive shaft. The assembly includes a housing that encloses the electric motor, the gearbox assembly, and the output shaft in co-axial alignment with respect to a central axis.

A Lubrication system for an engine component of a gas turbine engine, such as a planetary gearbox. The system comprises a main lubrication system comprising a main tank configured to supply lubricant to the engine component, and a main reservoir configured to collect lubricant scavenged from the engine component after lubrication; and an auxiliary lubrication system comprising an auxiliary reservoir configured to collect lubricant scavenged from the engine component after lubrication and to supply scavenged lubricant to the engine component. Main reservoir comprises an interior and the auxiliary reservoir is located within the interior of the main reservoir. The auxiliary reservoir comprises an upper portion, a lower portion and a lubricant pickup region, the upper portion comprising an opening arranged to permit lubricant to overflow into the main reservoir, and the lower portion of the auxiliary reservoir being shaped to cause lubricant to drain towards the lubricant pickup region.

A transmission device for a motor vehicle includes a gearwheel space, a gearwheel received in the gearwheel space and having at least one oil bunker for supplying oil for lubricating the gearwheel, and at least one oil return device. The oil is conveyable from the oil bunker into the gearwheel space. At least one oil sump for catching the oil is arranged in the gearwheel space. At least one partition is arranged between the oil bunker and the oil sump for separating the oil sump from the oil bunker. The at least one oil return device includes at least one wiper for wiping the oil from the gearwheel and at least one outlet for removing the wiped oil into the oil bunker. The wiper and the outlet are arranged on different sides of the at least one partition and are connected by at least one fluid connection.

A vehicle is provided. The vehicle may include a vehicle floor that defines a transmission tunnel and a crossmember. The crossmember may include a pair of longitudinal beams disposed along and sandwiching sled runners to the floor. Crossbeams may extend from and span between the pair to define an inner periphery that extends below and surrounds an outer periphery of an oil pan. One or more of the crossbeams may cap a tunnel that is defined by the floor.

A fluid sump for accommodating a lubricating fluid and transmission housing for a vehicle comprising such a fluid sump. The fluid sump may comprise a first compartment for collecting the lubricating fluid, a second compartment in which the lubricating fluid can be brought in contact with a rotating member, and an intermediate compartment having a first opening for introducing the lubricating fluid from the first compartment into the intermediate compartment, a second opening for introducing the lubricating fluid from the intermediate compartment into the second compartment, and a floating element. In one or more examples, the first opening can be opened and closed by the floating element, and the first compartment, the intermediate compartment and the second compartment are provided with ambient pressure.

A disconnecting axle includes a housing assembly including a first end cap coupled to a first side of a housing member to define a clutch cavity, and a second end cap coupled to a second side of the housing member to define a differential cavity. The housing member can define a central bore, a sump, and a plurality of passages. The central bore extends axially between the clutch and differential cavities. The sump can be spaced apart from the clutch and differential cavities, and the central bore. A clutch passage couples the clutch cavity to the sump. A differential passage couples the differential cavity to the sump. A first output member of the differential extends axially within the central bore. A piston is configured to compress friction plates to selectively transmit torque. A pump can pump fluid from the sump to the cylinder to move the piston.

An oil supply system includes a first oil receptacle collecting oil from a transmission and a second oil receptacle collecting oil from the rest of a drive system using gravity. Oil supply pump(s) supply oil from the oil receptacle(s) to the different consumers. A vacuum pump generates a negative pressure in the first oil receptacle and in the transmission casing connected to the first oil receptacle. A gas check valve prevents gas from flowing between the oil receptacles when a pressure differential is applied to the oil receptacles by the vacuum pump. An oil check valve prevents oil from flowing between the oil receptacles when the pressure differential is applied. An oil regulating valve may control the oil flow between the first and second oil receptacles. The oil supply system provides a simpler configuration without scavenging pump(s).

The invention relates to a lubrication system and a-method for controlling the lubrication system. The lubrication system comprises a bypass line by which it is possible to lead a part of the oil flow in the oil line past a component to be lubricated and back to the oil sump, a first valve configured to regulate the oil flow through the bypass line and a control unit. The control unit is configured to receive information from at least one parameter related to the oil flow to said component to estimate a required oil flow to said component in view of said parameter and to regulate the first valve such that a part of the oil flow in the oil line is led to the bypass line and that a remaining part of the oil flow, which corresponds to the required oil flow, is led to said component.
