ABSTRACT:
A transfer case assembly is disclosed as comprising two output shafts rotatably supported within the transfer case housing in a coaxially relationship and connected to the output hubs of a two-way roller clutch. The transfer case input shaft is rotatably supported within the housing in a parallel relationship to the output shafts. A chain drive sprocket is rotatably mounted on the input shaft directly coupled to the two-way roller clutch by an endless drive chain. A speed reduction unit is provided in the form of an intermediate shaft rotatably supported within the housing parallel to the input shaft and extending through the open middle loop area of the endless drive chain, and a gear cluster including a first drive gear rotatably mounted on the input shaft, a second larger drive gear fixed on the one end of the intermediate shaft in constant mesh with the first drive gear, and a third drive gear fixed on the other end of the intermediate shaft and in constant mesh with an integral gear portion of the chain drive sprocket. To selectively provide two-speed operation, a clutching means having two positions is provided for coupling the input shaft in a non-rotational relation to either the first drive gear or the chain drive sprocket.
