EFFICIENT LIGHT WEIGHT TRANSFER CASES FOR FOUR WHEEL DRIVE VEHICLES

Three transfer case models to improve the fuel economy of four-wheel-drive vehicles have been designed and developed for production. Improved economy is obtained by (1) minimizing churning and friction losses for highway made two-wheel-drive operation, (2) minimizing the weight of the transfer case assembly, and (3) providing low-range transfer case ratios compatible with the lower numerical axle ratios demanded for highway fuel economy.
