ABSTRACT:
A disconnect assembly which is positioned between respective sections of the torque bar for control column controls and permits alternative connection or disconnection of the sections of the control torque bar. This disconnect structure can be included on any or all of the control column torque bars for operating any of the control surfaces of the aircraft.
The torque tube disconnect assembly includes a lever rotatably attached to one side of the first torque tube section which has a pair of recesses and a central recess for receiving a pin mounted on a swivel bar. The opposite end of the swivel bar has an interconnect apparatus for engaging the end of the second torque tube section immediately adjacent the first torque tube section. The swivel bar has a pair of arms on either side thereof each of which rotatably supports a separate articulated link for each such arm. The opposite end of each such link is attached to an axle on a mount fixedly attached to said first torque tube section. When a sufficient amount of force is exerted on the un-jammed control, the connection of the swivel arm to one side of the torque tube will disconnect due to the force applied overcoming the force of the spring holding connection in place. Dependent upon the direction the control column is moving the swivel arm will reset to one or the other of the recesses. When disconnect occurs the bottom of the swivel bar is pulled upward by the force of the spring and disengages from opposite torque tube which disengages one control column from the other.
