Problems solved by technology

Usually, the supporting functional parts are set with a rigid stop for pressing the bearing, and the pulling bearing is maintained by the elastic parts, which will reduce the reliability of the mechanism pulling the bearing and locking, increase the difficulty of the design of the elastic parts, and bring about difficulty in structural layout, increased weight, and reliability. Sexual decline and other issues

Abstract

The invention discloses a folding piece unfolding, supporting and locking device. The device comprises a first supporting rod and a second supporting rod, the opposite ends of the first supporting rodand the second supporting rod are hinged through a first hinge shaft, the other end of the first supporting rod is provided with a first hinge shaft hole used for being hinged to the folding piece, and the other end of the second supporting rod is provided with a second hinge shaft hole used for being hinged to the main structure; a locking mechanism is arranged between the first supporting rod and the second supporting rod, the locking mechanism comprises a lock actuating cylinder, a piston rod, a first rocker arm, a second hinge shaft and a connecting assembly, the connecting assembly comprises a first hinge part, a second hinge part, a second rocker arm and a third supporting rod, the first hinge part is arranged on the first supporting rod, and the second hinge part is arranged on thesecond supporting rod. The locking mechanism is designed in a coordinated mode, two eccentricity parts and corresponding pulling direction and pressing direction two-way rigid locking are arranged, and the bearing capacity and the locking work reliability of the mechanism are improved.

Description

technical field [0001] The invention relates to the technical field of aircraft structural part design, in particular to a folding part unfolding support locking device. Background technique [0002] The functions of the supporting functional parts of the landing gear are as follows: a) as one of the main load-bearing parts of the landing gear, the two-way rigid stop is unfolded and locked, and the pillar of the landing gear is reliably locked in the lowered position to bear the tensile and compressive loads; b ) The transmission component in the process of retracting and extending the landing gear strut, unlocked and folded, and moves in coordination with the landing gear strut to transmit the retracting and releasing load. Usually, the supporting functional parts are set with a rigid stop for pressing the bearing, and the pulling bearing is maintained by the elastic parts, which will reduce the reliability of the mechanism pulling the bearing and locking, increase the diff...
