Abstract
Disclosed is a vehicle having an engine (20) transversely mounted for rocking motion relative to the vehicle frame (42); 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 belt drive (32, 34, 36) for rotating the fan in response to rotation of the crankshaft; means (100 or 120) for maintaining the belt tension relatively constant when the engine rocks; and means (29 or 121) to vary the fan speed relative to the crankshaft speed in response to the cooling requirements of the engine. In one embodiment the tensioning means is incorporated in split pulley (36) of the belt drive, in the other embodiment the tensioning means is a spring load idler pulley (120). In one embodiment the means to vary the fan speed in response to cooling requirements is a viscous coupling, in the other embodiment it is an electromagnetic clutch.
