Abstract
A four-wheel drive transfer case including a force sensor and associated electronics for sensing the reaction forces on driven members within the transfer case, such as in association with an output shaft and its bearings. The force sensor and associated control system establish an output signal which varies depending upon the magnitude of the reaction force and yields an indication of the torque distribution between the output shafts of the transfer case. The output voltage signal is used by a torque monitoring and control system to vary and/or limit the magnitude of torque transmitted to the output shaft.
