Abstract
Two embodiments of V-belt tensioning devices are employed in a cooling system of a vehicle having an engine (20) transversely mounted for rocking motion relative the vehicle frame (42). The cooling system includes an engine cooling radiator (22) mounted forwardly of the engine and substantially parallel to the rotational axis of the engine crankshaft; a cross-flow fan (24) having a rotational axis fixed against movement relative to the vehicle frame, substantially parallel to the crankshaft axis, and between the crankshaft axis and the plane of the radiator; a V-belt drive (32, 34 36) for rotating the fan in response to rotation of the crankshaft; and the two embodiments of the tensioning devices which maintain the V-belt tension as the distance between the crankshaft and fan axes varies in response to rocking motion of the engine. In one embodiment the tensioning device (90) is a split pulley (36). In the other embodiment the tensioning device (108) is a spring loaded idler pulley (110).
