A device (1) for cooling and lubricating components of a vehicle (2) may include a housing (3), a coolant sump (4), a coolant pump (5) for pumping coolant (6) from the coolant sump (4), a heat exchanger (7) for cooling coolant (6) from the coolant pump (5), and a coolant line system (8) including a coolant reservoir (9) having a single coolant inlet (10) and multiple coolant outlets (11.1, 11.2, 11.3, 11.4, 11.5). The coolant line system (8) fluidically connects the coolant pump (5) to the heat exchanger (7), and the heat exchanger (7) to the single coolant inlet (10) of the coolant reservoir (9). The coolant reservoir (9) receives coolant (6) from the heat exchanger (7) via the single coolant inlet (10) and directs coolant (6) via the multiple coolant outlets (11.1, 11.2, 11.3, 11.4, 11.5) onto components in the housing (3) requiring cooling and lubrication.

A portal gear box assembly for an all-terrain vehicle includes: a portal gear box housing a set of gears and linking an axle to an output shaft; a lubricating oil contained in the gear box; and a fluid circulation loop that circulates a cooling fluid to a cooling location outside the gear box. The cooling fluid may be a lubricating oil. The fluid circulation loop may include a pump and/or a filter. The cooling location may pass the fluid through a structure such as a radiator or other cooler. The circulation loop and/or any radiator/cooler, filter, or pump contained therein, may serve a single portal gear box, or may serve two or more portal gear box assemblies.

The present invention provides a transmission mechanism with which a deterioration in accuracy can be suppressed and a service life can be increased by suppressing lubricant deterioration. A transmission mechanism is provided with a housing, a first rotating member which is accommodated in the housing and which is capable of rotating about a first rotating member axis, and a lubricant which is accommodated in the housing to lubricate the first rotating member, wherein: the transmission mechanism is additionally provided with a first filter member which is accommodated in the housing to filter out dust contained in the lubricant; the lubricant is agitated by means of the rotation of the first rotating member about the first rotating member axis; and the first filter member is provided in the direction in which the lubricant is caused to flow by means of the agitation from the first rotating member.

A transmission filter includes two outlets. One outlet, adapted to feed an engine-driven pump, protrudes diagonally from the front of the filter. The first outlet is sealed to the inlet of the engine-driven pump by a radial seal. The second outlet is arranged in a rear extension and is sealed to the inlet of an electric pump by a compression seal. The differing types of seals and relative orientations of the outlets make the assembly less sensitive to dimension variation due to production and assembly tolerances. The relative locations of the outlets also mitigate any flow interactions between the pumps when both operate simultaneously.

A method and a system for monitoring a mechanical system, the mechanical system including a lubrication system provided with a reservoir containing a lubricating liquid, with a lubrication circuit designed to lubricate the mechanical system, as well as with a particle detection device arranged in the lubrication circuit. The detection device makes it possible, in particular, to count the number of particles flowing through the lubrication circuit and/or the flow rate of the particles. Comparing that number or that flow rate with a first threshold makes it possible to determine a risk of damage affecting the mechanical system and to anticipate the maintenance or reinforced monitoring operations that possibly need to be performed.

The present invention provides an oil pump device capable of preventing foreign matters from getting caught at a sliding part of an oil pump, and thus of preventing a situation where the oil pump is locked and prevented from rotating. The oil pump device includes an oil pump connected to a supply target apparatus by a hydraulic circuit, the oil pump discharging and supplying oil to the supply target apparatus through the hydraulic circuit; a motor driving the oil pump; a trapping member interposed along the hydraulic circuit, the trapping member trapping a foreign matter mixed in the oil discharged from the oil pump; and a motor control unit controlling the motor to perform a normal control mode of driving the oil pump in a normal control rotation range and perform, at operational start of the oil pump, a lock-avoiding mode of driving the oil pump with a lock-avoiding rotational speed set in advance as a lower limit.

An assembly is provided for a turbine engine. This turbine engine assembly includes a journal bearing and a filter. The journal bearing has an internal bearing bore. The filter is arranged within the internal bearing bore. The filter includes a tubular filter element and a first end cap. The tubular filter element extends axially along an axis between a first end and a second end. A perforated portion of the tubular filter element is radially disposed away from the journal bearing by a cavity. The first end cap is mounted to the tubular filter element at the first end. The first end cap is sealed radially against the journal bearing by a first interference fit.

A gear box includes a casing having an interior. A rotating component is arranged in the interior of the casing. A bearing including a rotating element, and a fixed element is connected with the casing in the interior. A submersible pump is arranged in the interior of the casing. The submersible pump includes a first housing portion extending about the rotating component fixedly mounted to the casing at the interior. A second housing portion is fixedly mounted to the casing at the interior and is aligned with the first housing portion. The first and second housing portions form a lubricant reservoir which holds lubricant. An impeller is mounted to the rotating component and arranged in the lubricant reservoir. One of the first and second housing portions includes an outlet through which the pumped lubricant is directed toward the rotating element.

A demister for a gearing system includes a main body having an inner annular rim coupled to an outer annular rim through a first wall and a second wall opposite from the first wall. The main body is configured to be rotated about a central longitudinal axis to create centrifugal forces that separate oil mist particles from air. First fluid passages extend radially between and through the inner annular rim and the outer annular rim. The first fluid passages include a fluid inlet opening in the outer annular rim and a fluid outlet opening in the inner annular rim. The fluid inlet opening is configured to accept incoming air. The fluid outlet opening is configured to discharge filtered air.

An electrically-operated electric drive module for use in a vehicle framework that is configured for a powertrain that includes an internal combustion engine. The electrically-operated electric drive module permits the vehicle to be converted to an electrically propelled vehicle in a manner that is cost-effective and which is relatively low in weight.
