ABSTRACT:
A multiple-disc clutch type electronically controlled differential limiting device comprises a differential gear, a hydraulically actuated multiple-disc clutch operably disposed between a differential case and a differential side gear to produce, a differential limiting torque by engagement of the clutch, and a differential limiting controller which derives a wheel-speed difference between-right and left driven wheels and hydraulically controls an engaging force of the clutch to increasingly compensate the engaging force in accordance with an increase in the wheel-speed difference. A torsional damper is internally accommodated in the associated drive shaft. A resonance frequency of the torsional damper is set to be equal to a resonance frequency of a torsional vibration system which is constructed by a peripheral member of the differential acting as a mass moment of inertia with respect to the axis of the associated drive shaft and each drive shaft acting as a torsional spring.
