Title:
EXTERNAL CONTROL TYPE FLUID JOINT
Document Type and Number:
Japanese Patent JP2017227313
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an external control type fluid joint which can transmit rotation torque to a housing and a drive object which is integrated with the housing even if an abnormality occurs in an electromagnet and its power supply system.SOLUTION: An external control type fluid joint comprises: a drive disc 40 fixed to a rotating shaft 10; a housing 30 for forming internal spaces 34; a partitioning plate 60 for defining the internal spaces 34 in a working chamber 34b for accommodating a drive disc 40, and a storage chamber 34a for storing fluid; a supply hole 62 which is formed at the partitioning plate 60, and supplies the fluid to the working chamber 34b from the storage chamber 34a; a valve main body 73 composed of a magnetic body which can open and close the supply hole 62; and an electromagnet 21 for generating a suction force between the valve main body 73 and itself so that the valve main body 73 is displaced to a blocked state for blocking the supply hole 62. The valve main body 73 is connected to the housing 30 so as to be turnable, and its center of gravity is set so as to turn to a side at which the supply hole 62 is opened by a centrifugal force which acts accompanied by the rotation of the housing 30.SELECTED DRAWING: Figure 1
