ABSTRACT:
A ball joint connection for the torque scissors of aircraft landing gear provides realignment of the scissors during stroking of the piston to avoid the usual distortion and wearing of parts in the conventional straight pin hinge. Quick disconnect of the scissors for aircraft towing is accomplished through the simple expediency of rotating the ball portion of the scissors design, upon which two diametrically opposed flats have been machined. The scissors can thereby be easily and quickly disconnected prior to towing and then reconnected for the torque transfer operation. As an added feature a ball rotating and locking device is provided as an integral part of the scissors assembly.
