Abstract: A lubrication device for a vehicle drive-force transmitting apparatus that includes a casing, such that an interior of the casing is sectioned by a partition wall into a gear room and a motor room. A communication hole is provided through the partition wall to communicate between the gear room and the motor room. The communication hole has a gear-room-side opening and a motor-room-side opening, and opens at the gear-room-side opening in the gear room and at the motor-room-side opening in the motor room. The motor-room-side opening is located on an upper side of a bearing which supports a gear mechanism provided in the gear room and which is held in a bearing holding wall of the casing. The gear-room-side opening is provided in the bearing holding wall, and is in held in communication with a gap defined between an inner race and an outer race of the bearing.

Abstract: A drive module for a vehicle including an electric machine, an inverter, a gearing assembly, and a cooling system. A first housing member thermally coupled with the inverter has a first set of heat exchange surfaces and a second housing member thermally coupled with the electric machine has a second set of heat exchange surfaces. The first and second sets of heat exchange surfaces each project into an interior volume cooled by an externally supplied liquid coolant which thereby defines a heat exchanger. A lower oil sump for collecting oil used to cool the electric machine may also include heat exchange surfaces projecting into the same heat exchanger. The gearbox may include an elevated oil sump which is supplied by the same oil pump circulating oil on the electric machine wherein the elevated oil sump gravity feeds oil onto selected surfaces within the gearbox.

Abstract: The disclosure relates to a generator and a wind turbine. The generator includes an active cooling loop and a passive cooling loop that are isolated from each other and both are in communication with external environment. The active cooling loop includes cavities that are in communication with each other and located at two respective ends of the generator in an axial direction, an air gap between a rotor and a stator of the generator, and radial channels arranged at intervals and distributed along the axial direction of the stator. A cooling device in communication with the external environment is disposed in the active cooling loop. The passive cooling loop includes an axial channel extending through the stator in the axial direction and an outer surface of the generator.

Abstract: An apparatus for providing mobile electric power includes a power generation transport. The power generation transport includes an air inlet filter housing, an inlet plenum coupled to the air inlet filter housing, an exhaust collector, an exhaust implement coupled to the exhaust collector, a gas turbine, a generator driven by the gas turbine, and an elevating system configured to elevate the exhaust implement to convert the power generation transport to an operational mode, and lower the exhaust implement back down to convert the power generation transport to a transportation mode. The elevating system performs the elevating and the lowering without utilizing any external mechanical apparatus. The air inlet filter housing, the inlet plenum, the exhaust collector, the exhaust implement, the gas turbine, the generator, and the elevating system are mounted on the power generation transport.
