A torque link member for aircraft landing gear includes a first end for connecting to a lower portion or an upper portion of the aircraft landing gear and a second end for connecting to another torque link member. A locking pin is disposed on one of the upper portion, the lower portion, the first end or the second end. The locking pin is axially movable between an engaged position wherein the pin protrudes for interengagement with a cooperating aperture on the first end, the second end, the upper portion, the lower portion, or the second end of the other torque link member, and a disengaged position. The locking pin is biased toward the engaged position and movable against the biasing to the disengaged position.

A quick release assembly for an aircraft landing gear strut, the strut having an upper portion and a lower portion that is telescopingly and rotatably movable relative to the upper portion, an upper torque link member has a first end connected to the upper portion, a lower torque link member has a first end connected to the lower portion, second ends of the torque link members are connected together to prevent relative rotation between the upper and lower portions, comprising: a locking pin disposed on a first member wherein the first member is one of the upper portion, the upper torque link member, the lower torque link member or the lower portion; anda cooperating structure disposed on a second member wherein the second member is another of the upper portion, the upper torque link member, the lower torque link member or the lower portion;and wherein the locking pin is axially urged toward an engaged position wherein the locking pin cooperates with the cooperating structure of the second member when the locking pin and the cooperating structure are aligned to connect the first and second members together, the locking pin axially movable against the urging from the engaged position to a disengaged position to disconnect the first and second members;and further wherein the locking in includes a handle portion, a stationary cap fixed to the first member, a slider tube that slides inside the stationary cap and together with the handle portion between the engaged position and the disengaged position, and a spring that axially urges the locking pin toward the engaged position, the spring interposed between a head portion of the handle portion and a radial flange of the slider tube, and received radially within an annular space defined by an annular wall portion of the slider tube. 8. The quick release assembly of claim 7, wherein a bore size of the stationary cap of the first member and a bushing bore of the cooperating structure are substantially the same size, and a section area of a connecting side of the slider tube is slightly smaller than the bore size of the stationary cap of the first member and the bushing of the cooperating structure. 9. The quick release assembly of claim 7, wherein the slider tube and the bushing of the cooperating structure are tapered to cooperatively engage one another when the locking pin is in the engaged position. 10. The quick release assembly of claim 7 wherein the first member has at least a three-pronged portion, and the second member has at least a two-pronged portion, and the locking pin is one of two locking pins disposed on both sides of the first member. 11. The quick release assembly of claim 10, wherein the first member has a four-pronged portion, and the second member has a three-pronged portion. 12. The quick release assembly of claim 7, wherein the first member is the lower torque link member and second member is either the upper torque link member or the lower portion. 13. The quick release assembly of claim 7 further including: a second locking pin disposed on the first member;a second cooperating structure disposed on the second member;the second locking pin axially urged toward an extended position wherein the second locking pin cooperates with the second cooperating structure of the second member when the second locking pin and the second cooperating structure are aligned to connect the first and second members together, the second locking pin axially movable against the urging from the extended position to a retracted position, both the first and second locking members in the retracted positions allow disconnection of the first and second members. 14.
