Supershaft, that is a torque differentiating trans-axle. It has servos which modulate clutch drag to planetary gear sets which modify the output ratios.
And the "torque sensing" in a clutch or cone type occurs when the rotational force of the carrier applies pressure against the spider gears via the spider gear pin from force generated by the rotation of the ring gear on the carrier. The torque sensing is not monitored and has no feedback mechanism other than the resistance of the inertia of the vehicle and the differential rotational speed of each axle.
The spider gears attempt to ramp up (separate) or leave engagment from the gears on the cone or the clutch face. This causes lateral opposing force linear to the axles outward. This causes high force applied to the cone or clutch to the left and to the right which compresses them between the carrier and the cone or clutch plates which are engaged to the axle which causes increased unison between the carrier and the two axles. Hence when energy is applied, the sure grip applies increased force to the posi traction process. It is brilliantly crude and effective.
