Abstract

The invention discloses an aircraft landing gear utilizing spring buckles, and belongs to the field of aviation equipment. The aircraft landing gear consists of a landing gear fixing device, a springsupporting rod I, a landing gear supporting rod, a hydraulic rod I, landing gear moving devices, a hydraulic rod II and a rotating shaft with a rotating shaft connecting rod, wherein the spring supporting rod I is arranged on the landing gear fixing device; one end of the landing gear supporting rod is fixedly arranged on the front end of a hydraulic rod III, and the other end of the landing gearsupporting rod is fixedly arranged on the rotating shaft with the rotating shaft connecting rod; the rotating shaft with the rotating shaft connecting rod is fixedly arranged on the landing gear fixing device; one end of a rotating shaft II is fixedly arranged on the rotating shaft with the rotating shaft connecting rod, and the other end of the rotating shaft II is fixedly arranged on spring supporting rods II on the landing gear moving devices; one end of the hydraulic rod II is connected with the rotating shaft with the rotating shaft connecting rod, and the other end is fixedly arranged onthe landing gear supporting rod. The aircraft landing gear disclosed by the invention has the beneficial effects that the stretching and contracting speed of the hydraulic rods is controlled by utilizing the spring buckles, and the stability is enhanced.

Description

technical field [0001] The invention relates to an aircraft landing gear utilizing a spring buckle, in particular to an aircraft landing gear utilizing a spring buckle, and belongs to the field of aviation equipment. Background technique [0002] Landing gear is an accessory device used to support the aircraft and move on the ground (water surface) when the lower part of the aircraft is used for take-off and landing or ground (water surface) taxiing. The landing gear is the only part that supports the entire aircraft, so it is an integral part of the aircraft; without it, the aircraft cannot move on the ground. After the aircraft takes off, the landing gear can be retracted depending on the flight performance. Landing gear is an important load-bearing and manoeuvrable part of an aircraft, which plays an extremely important role in the safe take-off and landing of the aircraft. Landing gear is a necessary support system for aircraft takeoff, landing, taxiing, ground movemen...
