Abstract
A vehicle drivetrain (16) disclosed includes a viscous clutch (30) that is driven by an auxiliary output (52) of a transaxle (28) to provide four-wheel driving when needed while providing two-wheel driving at other times. A selector (54) is preferably incorporated to selectively (a) disconnect the auxiliary output (52) of the transaxle from the pair of wheels not normally driven thereby, (b) connect the auxiliary output (52) of the transaxle to the second pair of wheels through the viscous clutch (30), or (c) connect the auxiliary output (52) of the transaxle to an output (60) of the viscous clutch (30) in a bypassed relationship to the clutch. The drivetrain (16) has particular utility when utilized with a transversely mounted front engine and can be utilized with a transaxle (28) of either the automatic or manual shifting type.
