ABSTRACT:
A torque fuse for a vehicle driveline has a sleeve splined at one end to the vehicle power transmission output shaft with the other end clip-splined to the driveshaft yoke. An intermediate pre-weakened frangible area of the sleeve is designed to rupture at a torque level less than the critical torque level of the driveshaft. A washer swaged into the sleeve enables the sleeve to be bolted to the end of the transmission output shaft. An auxiliary tailstick bolted to the transmission case has an auxiliary bearing to support transverse loads on the sleeve at the yoke end thereof.
