Delay restoring type limit-torque coupling mechanism

摘要

The present invention relates to a limit-torque coupling mechanism with delay restoring function, which is characterized in that, when the relative coupling portion is forced by torque to reverse the limit-torque coupling mechanism has delay restoring function to reduce noise and frictional loss arising from subsequently relative sliding so as to restore coupling during the decrease in torque difference or speed difference. The means to accomplish the aforesaid function lie in that, to design the torque coupling mechanism being forcibly reversed with such characteristics as mechanical friction damping, fluid damping or magnetic damping or the like.
