A gear unit having a shaft, particularly an input shaft, a fan impeller being joined in rotatably fixed manner to the shaft, a fan cowl, which at least partially surrounds the fan impeller, being mounted on the gear housing, a separating plate for separating the pressure chamber of the fan from the suction chamber of the fan being joined to the fan cowl, the separating plate having an air inlet for the fan impeller and being disposed on the side of the fan impeller facing away axially from the gear unit.

A continuously variable transmission for a vehicle includes a drive clutch, a driven clutch operably coupled to the drive clutch, and a belt extending between the drive and driven clutches. The continuously variable transmission also includes an inner cover and an outer cover removably coupled to the inner cover. At least one of the inner and outer covers includes an air inlet for providing cooling air to the drive and driven clutches and the belt.

A power unit includes a prime mover and a belt continuously variable transmission. The belt continuously variable transmission includes a drive pulley, a driven pulley, a belt wound around the drive pulley and the driven pulley, and a housing forming an accommodation space in which the belt is disposed. The belt continuously variable transmission changes a speed of rotation produced by drive power output from the prime mover. The power unit further includes a temperature sensor configured to detect a temperature of the belt or a temperature corresponding to the temperature of the belt.

A cover for a transmission having improved airflow path is disclosed. The interior of the cover has a progressively narrowing airflow path to reduce pressure drop through the cover, thereby improving the cooling efficiency of the airflow through the cover. The cover includes a diverter sheltering the air inlet to the cover to prevent air in the cover from exerting outward pressure on the incoming air.

A cover for a heat source according to an exemplary aspect of the present disclosure includes, among other things, a first portion covering at least a portion of the heat source, and a second portion including a first latch and a second latch. Each of the first and second latches are configured to engage a fluid conduit. An assembly is also disclosed.

A continuously variable transmission for a vehicle includes a drive clutch, a driven clutch operably coupled to the drive clutch, and a belt extending between the drive and driven clutches. The continuously variable transmission also includes an inner cover and an outer cover removably coupled to the inner cover. At least one of the inner and outer covers includes an air inlet for providing cooling air to the drive and driven clutches and the belt.

A vehicle includes a frame, at least one traction device coupled to the frame for facilitating movement of the vehicle, an implement coupled to the frame and configured to perform a work operation, a gearbox, a hydraulic system having a hydraulic reservoir, and an oil cooling system configured to cool the gearbox and the hydraulic system. The oil cooling system includes first and second circuits for a cooling oil, and a crossover circuit. The first circuit includes the gearbox and a first oil-to-air cooler configured to cool the cooling oil from the gearbox. The second circuit includes the hydraulic reservoir and a second oil-to-air cooler for cooling the cooling oil from the hydraulic reservoir. The crossover circuit includes the gearbox and the hydraulic reservoir and is configured to exchange the cooling oil between the gearbox and the hydraulic reservoir to provide heat transfer between the first and second circuits.

A work machine including a prime mover, an electric motor, an electric motor fluid circuit, a transmission fluid circuit, a hydraulic circuit, a cooling circuit, a pump, and a controller. The electric motor may supply a portion of power of the prime mover. The electric motor fluid circuit may be adapted to remove waste heat from the electric motor. The transmission fluid circuit may be adapted to lubricate a moving part of a transmission powered by the prime mover. The hydraulic circuit may be adapted to transmit power from the prime mover to a moving component of the work machine. The cooling circuit may be absorbing waste heat from one or more of the electric motor fluid circuit, the transmission fluid circuit, and the hydraulic circuit. The control may be adapted to control diversion of a portion of waste heat from the cooling circuit to a portion of the cab.

A damper and pulley assembly for an internal combustion engine is disclosed. The damper and pulley assembly, including a pulley closely fitted between two dampers, is configured to have increased air movement for heat dissipation while conforming to low spacing requirements of an engine compartment. The pulley can have multiple slots along its two side surfaces and openings located in the slots. The slots and openings of the pulley are aligned with openings of the two dampers, and facilitate air movement through the pulley and around the dampers.

A lubricant cooler, a cooling and lubricating system of a speed-up gear box, a wind power unit and a low-temperature starting method of the wind power unit. The lubricant cooler includes a radiating plate and a one-way valve arranged on a lubricant conveying pipeline, wherein the radiating plate and the one-way valve are arranged in parallel, and the one-way valve and/or the lubricant conveying pipeline in communication with the one-way valve are integrated on the radiating plate. The lubricant cooler can solve the problem that, when the wind power unit is started at a low temperature, the cooling and lubricating system of the speed-up gear box causes the shut-down of the wind power unit because the lubricant blocks the radiating plate.
