A lower connection structure of a landing gear buffer

Abstract

This application belongs to the technical field of landing gear structure design, and particularly relates to a lower connection structure of a landing gear buffer, wherein the buffer includes: an outer cylinder, and a piston rod, one end of which is arranged inside the outer cylinder; the lower connection structure includes: a rotating sleeve The cylinder is sleeved on the outer circumference of the outer cylinder, and an ejection connection structure is provided outside it, and the ejection connection structure is used to connect with the ejection rod; one end of the bearing nut is arranged between the rotating sleeve and the outer cylinder, which is called the upper end of the bearing nut. The other end is called the lower end of the bearing nut; the inner wall of the upper end of the bearing nut is connected with the outer wall of the outer cylinder through a zigzag thread, and the outer wall of the upper end of the bearing nut and the inner wall of the rotating sleeve pass through the bearing groove opened along the circumferential direction and the outer wall arranged along the circumferential direction. The load-bearing projection fits in connection; wherein, the rotating sleeve can rotate relative to the load nut.

Description

technical field [0001] The application belongs to the technical field of landing gear structure design, and in particular relates to a lower connection structure of a landing gear buffer. Background technique [0002] Aircraft landing gear is designed to ensure the safety of the two stages of takeoff and landing, and its core component is the buffer, which is used to consume the sliding load of the aircraft during the two stages of takeoff and landing. The lower connection structure is designed on the landing gear buffer to transfer the loads such as wheels and tires to the landing gear and aircraft structure. [0003] At present, the load-bearing nut of the lower connection structure of the front landing gear buffer of a catapult take-off carrier-based aircraft bears an ejection load of more than ten tons during the catapult take-off. In the traditional lower connection structure, the load-bearing nut and the landing gear buffer adopt ordinary or MJ tooth type. The threade...

Problems solved by technology

[0003] At present, the load-bearing nut of the lower connection structure of the front landing gear buffer of a catapult take-off carrier-based aircraft bears an ejection load of more than ten tons during the catapult take-off. In the traditional lower connection structure, the load-bearing nut and the landing gear buffer adopt ordinary or MJ tooth type. The threaded connection cannot meet the requirements of transmitting high loads
