gear pinions mesh to provide the normal speed differential action. In the event of wheel slip, torque bias is generated by the axial and radial thrusts of the pinions in the pockets. The resultant friction force enables the driving road wheel and sun gear to transmit a greater proportion of the torque. This effect is progressive but at no stage does the differential lock solid, hence the inherent safety of the QUAIFE Automatic Torque Biasing differential. The latest competition development of this differential uses pressure pads on the ends of the pinions with which we can vary the amount of slip according to driver preference.". Regards, Jim
