摘要： An engine assembly is provided that includes an engine having a crankshaft that is caused to rotate response to a firing of the engine, a backplate affixed to the engine and comprising one or more air flow passages formed therethrough, and an engine cooling fan operatively coupled to the crankshaft so as to be rotated by the crankshaft, the engine cooling fan coupled to the crankshaft on a side of the backplate opposite the engine. The engine assembly also includes a fan cover mounted over the engine cooling fan and secured to the backplate, the fan cover including an opening through which an air flow is provided to the engine cooling. The backplate and the fan cover collectively form an air guide that directs a flow of cooling air generated by the engine cooling fan through the one or more air flow passages of the backplate and to the engine.

摘要： A power transmission roller assembly includes a power transmission roller configured to be brought into contact with the driving roller and the driven roller, a pivot shaft fixed to a vehicle body, a pivot arm arranged radially inside of the power transmission roller and pivotally mounted on the pivot shaft, and a roller support bearing rotatably supporting the power transmission roller. A pair of biasing members are mounted to the pivot arm and bias the roller support bearing to a predetermined position between the driving roller and the driven roller such that the abutment force between the driving roller and the power transmission roller is balanced with the abutment force between the driven roller and the power transmission roller. Sliding members are mounted on respective shafts of the biasing members to extend through the sliding members, and frictional forces are generated between the sliding members and the respective shafts.

摘要： A transmission includes an input shaft, and a primary drive gear fixed to the input shaft. The primary gear has a first set of gear teeth. An idler gear is disposed in the transmission and has a second set of gear teeth in meshing engagement with the first set of gear teeth. The transmission also includes a transmission-pump drive gear having a third set of gear teeth in meshing engagement with the second set of gear teeth. The transmission-pump drive gear is configured to transmit power from the input shaft to a transmission pump. A power take-off unit is mounted to a case of the transmission and includes a first unit drive gear having a fourth set of gear teeth in meshing engagement with the second set of teeth. The a first unit drive gear is configured to transmit power from the idler gear to the power take-off.
