The power pack also includes a sub-transmission selected from a group of different sub-transmissions depending on the selected vehicle. The selected sub-transmission is mounted to the housing of the CVT. The housing of the CVT is configured to mount any sub-transmission of the group of different sub-transmissions. A method for assembling a power pack is also provided.

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 heat control device (1) comprises: a radiator (12) that cools cooling water for cooling a vehicle engine (11); a transmission (13) that transmits the power generated at the engine (11); an air-cooling type oil cooler (14) that cools the transmission oil for cooling the transmission (13) by heat exchange with the air outside the vehicle; a water-cooling type oil cooler (15) that cools the transmission oil by heat exchange with the cooling water; and a flow path switching unit (16) that switches between causing the transmission oil to flow into the air-cooling type oil cooler (14), or causing the transmission oil to flow into the water-cooling type oil cooler (15).

An air intake system for a vehicle has a conduit having an internal wall forming an air passage. A deflector is disposed within the air passage. A restricting structure is disposed within the air passage between the deflector and a conduit outlet. The restricting structure defines at least in part an opening substantially laterally aligned with the deflector. The restricting structure has a lateral wall disposed downstream of the deflector and extending within the air passage. The lateral wall has a front surface generally facing a conduit inlet, and a plurality of surface-increasing features provided on the front surface. Each of the surface-increasing features has a length of at least 1 mm measured from the front surface in a direction normal thereto. An air intake system having a collector connected to the deflector and positioned to collect at least some moisture from air flowing past the deflector is also described.

An axle assembly for a working machine is provided. The axle assembly has an axle housing comprising a central portion housing a gear, wherein the gear is configured to rotate about an axis and is configured to be partially disposed in a lubricant reservoir, and at least one arm portion extending from the central portion, with the arm portion housing at least one driveshaft. The axle assembly further includes a conduit assembly configured to direct lubricant from the central portion to the arm portion, with the conduit assembly including a lubricant catcher having an inlet disposed in an interior volume of the central portion.

Methods, systems, and vehicles that control the temperature of a device included in the vehicle are presented herein. The temperature of the device is controlled by ventilating the device with drivetrain air, such as transmission cooling air. In some embodiments, the device is at a greater temperature than the drivetrain air, which cools the device. In other embodiments, the device is at a lesser temperature than the drivetrain air, which heats the device. The drivetrain air is provided to the device through an exhaust duct coupled to the vehicle's transmission. The drivetrain exhaust air is preferably circulated by the transmission. The transmission may be a continuously variable transmission. The device may be an oxygen sensor that is coupled to an engine exhaust pipe. The oxygen sensor is thermally coupled to the engine exhaust and the engine exhaust pipe, which are at greater temperatures than the transmission exhaust air.

A power tool includes an electric motor having an output shaft, a transmission having a transmission housing, a spindle rotatable in response to receiving torque from the transmission and a pinion coupled to the output shaft. The pinion includes a bushing portion, a toothed portion for driving the transmission, and a cylindrical portion between the bushing portion and the toothed portion. The power tool further comprises a fan coupled to the bushing portion of the pinion and a bearing arranged between the cylindrical portion and the transmission housing for rotatably supporting the pinion and the output shaft.

A transmission includes a housing, a plurality of components, and a cooling system. The housing has a plurality of walls that cooperate to define an interior space and a sump configured to store lubricating fluid in use of the transmission. The plurality of components are arranged in the interior space and configured to cooperatively transmit rotational power between an input shaft and an output shaft of the transmission to reduce a rotational speed of the output shaft relative to a rotational speed of the input shaft in use of the transmission. At least one of the plurality of components is supplied with lubricating fluid stored by the sump in use of the transmission. The cooling system is supported by the housing.

A vehicle has an engine; a drive pulley connected to and driven by a crankshaft of the engine; a driven pulley; an output shaft connected to and driven by the driven pulley; a belt looped around the pulleys; and a cover connected to the engine. The cover and the engine define a volume therebetween. A baffle disposed in the volume separates the volume in first and second chambers. The first chamber is disposed between the baffle and the engine. The second chamber is disposed between the baffle and the cover. The pulleys are disposed in the second chamber. The baffle defines first and second apertures fluidly communicating the first chamber with the second chamber. An air inlet is fluidly connected to the first chamber. An air outlet is fluidly connected to the second chamber.
