Abstract
A four-wheel drive transfer case, that offers the maximum in mobility and control with minimum driver awareness and response, has been developed. The system is in four-wheel drive mode at all times. It contains a reverse cone differential with friction biasing characteristics for the purpose of relieving drive train wind-up while minimizing wheel breakaway and loss of traction. Design parameters were based on the concept of maximum performance within the limits of technology, mobility at extremes of tractive conditions, control, and cost.
