ABSTRACT:
A reversing drive or transmission is shown which is particularly useful for all-terrain vehicles. The drive includes a drive shaft and an intermediate axle spaced therefrom. The drive shaft and intermediate axle have respective pulley and drum assemblies mounted thereon in registration, with a V-belt coupling the drive and driven pulleys. A swing arm moves the intermediate axle toward and away from the drive shaft to tension the V-belt or alternatively engage the drive wheels for reverse rotation of the intermediate axle. An intermediate sprocket mounted on the intermediate axle drives a driven sprocket co-axially mounted on the pivot axis of the swing arm. The plane of rotation of the intermediate sprocket is transversely orientated with respect to the swing arm pivot axis, so that torsional forces on the intermediate sprocket tend to reinforce the engagement between the respective pulley and drum assemblies in the forward and reverse directions.
