HYDRAULIC POWER TRANSMISSION JOINT

摘要

PROBLEM TO BE SOLVED: To provide a hydraulic power transmission joint capable of preventing ABS interference and improving fuel efficiency at the time of high speed driving by obtaining acceleration sensitive type differential limiting force. SOLUTION: An inertial body 50 provided so as to be rotatable toward an input shaft and an output shaft with being connected to a cam member 40 through a spring member 60 is relatively rotated to a direction to contract the spring member against the cam member 40 by angular velocity of rotation of the input shaft, and an orifice 34 of a rotary valve 30 is thereby closed. The inertial body 50 is also relatively rotated to the reverse direction against the cam member 40 by energization force of the spring member 60 when the angular velocity is disappeared, and the orifice 34 of the rotary valve 30 is thereby opened.
