Abstract

The invention relates to a quick disassembling actuator cylinder. The quick disassembling actuator cylinder comprises an outer cylinder and a piston rod, wherein a stop clamping sleeve is detachably fixed at one end of the outer cylinder; a section of the piston rod penetrates through the stop clamping sleeve to extend into the outer cylinder, and a boss matched with the outer cylinder is arrangedat one end, extending into the outer cylinder, of the piston rod; a guide sleeve which sleeves the piston rod is arranged on the inner side of the stop clamping sleeve; and one side, far away from the stop clamping sleeve, of the guide sleeve is provided with a buffering mechanism which is in clearance fit with the piston rod and is integrally connected to the outer cylinder. According to the quick disassembling actuator cylinder, the impact load and the stress borne by the main bearing part of the actuating cylinder are reduced, and the structural life is prolonged.

Description

technical field

[0001] The invention relates to a quick-release actuator, in particular to an anti-fatigue hydraulic quick-release actuator. Background technique

[0002] With the continuous improvement of the performance of advanced military and civilian aircraft, the complexity and cost of the aircraft are also increasing rapidly, so the service life requirements of the aircraft are also greatly increased, and the durability of the landing gear is also put on the agenda. According to statistics, more than 80% of the accidents that occur when the landing gear is in use are caused by fatigue damage. Therefore, durability design has become one of the most basic and important requirements for designing new advanced aircraft components. As a common component of aircraft landing gear, quick-release hydraulic actuators have also received much attention for their durability.

[0003] The design related to the dynamic seal of the quick-release hydraulic actuator is the short boar...
