Airplane front damping undercarriage device

Abstract

The invention relates to the technical field of aeronautical manufacturing, and discloses an aircraft front damping undercarriage device which comprises a supporting rod, aircraft wheels are movably installed at the two ends of the supporting rod, a moving shaft is fixedly installed in the middle of one side of the supporting rod, and one end of the moving shaft is movably connected with a damping cavity in a sleeved mode. Through forward and reverse reciprocating motion of two sections of gas in the inner cavity of the damping cavity, the front impact force borne by the aircraft wheels is effectively reduced, the problem that the aircraft landing balance is unstable due to the fact that the aircraft wheels are collided in the front direction is solved, fixed teeth and clamping teeth are crossed and clamped, the problem that the piston rod and the shock absorber rotate and fall off due to the torque of a piston rod is solved, gas is divided into two gas flows through the fixed teeth, the gas flows collide with the clamping teeth in a split-flow mode, the clamping teeth generate relative extrusion force, the effect that the clamping teeth prevent the fixed teeth from rotating is effectively enhanced, and the problem that the piston rod rotates and is separated from a shock absorber due to torque generated by the piston rod is avoided.

Description

technical field [0001] The invention relates to the technical field of aviation manufacturing, in particular to a front shock-absorbing landing gear device for an aircraft. Background technique [0002] Landing gear is an accessory device used at the bottom of the aircraft to support the aircraft during take-off and landing or taxiing on the ground, and is used for ground movement. The landing gear device is an extremely important part of the aircraft with load-bearing and maneuverability, which plays an important role in the flight of the aircraft. Irreplaceable role, the existing landing gear is mainly composed of shock absorbers, retractable system, wheel and brake system, turning system, the most commonly used is the pillar type landing gear, its main feature is the Combined into one, the wheel is directly fixed on the piston rod of the shock absorber. Because of its simple structure, easy retraction, and low mass, it is widely used in modern aircraft. [0003] In the e...

Problems solved by technology

[0004] Aiming at the deficiencies in the use of existing aircraft proposed in the background technology, the present invention provides a frontal shock-absorbing landing gear device for an aircraft, which can effectively alleviate the frontal impact of the wheel on the ground, and at the same time, effectively prevent the piston from The advantage that the rod generates torque and rotates away from the shock absorber solves the technical problems raised in the background art above
