Disclosed are an electric wheel assembly applicable for a parallelly mounted dual-tire wheel, an axle, and a vehicle. The electric wheel assembly includes a wheel and support axle assembly, an internal-rotor hub motor, a planetary gear reducer and a brake system. A planetary carrier is connected to a hub. The hub is connected to a spoke and a rim. The wheel support axle passes through a rotor sleeve and is provided with a hub bearing to support the hub and a whole wheel. A sun gear disposed at an end of the rotor sleeve of the internal-rotor hub motor is a power input of the planetary gear speed reducer, and the planetary carrier is a power output. A planetary gear of the planetary gear reducer is a tower-shaped gear and realizes a relatively high transmission ratio under a condition that an axial length is relatively small.

Operating a machine system for co-production of electrical power and filtered potable water includes operating an electrical generator by way of rotation of an engine output shaft to produce electrical power, and collecting water condensed from cooled treated exhaust from the engine for delivery to an outgoing water conduit. Operating the machine system further includes supplying electrical power produced by the electrical generator to an in situ electrical load, and to at least one ex situ electrical load such as a power grid. The in situ electrical load is produced by at least one of an exhaust conveyance device, an air conveyance device, or a water conveyance device in a water subsystem.

An oil recovery structure for cooling a motor includes a rotor connected to a rotary shaft, a stator disposed on the rotor, a housing surrounding the rotor and the stator, and an oil housing disposed on the housing, in which the oil housing includes a first inlet through which the oil is introduced from a space defined on one side of the rotor, a second inlet through which the oil is introduced from a reducer connected to the rotary shaft, and a discharging port discharging the oil inside the oil housing to an oil filter.

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.
