Abstract

The invention discloses a composite material main lifting support and a manufacturing and assembling method thereof, and belongs to the technical field of aviation aircraft accessories. The compositematerial main lifting support comprises an arc-shaped plate and two side supporting plates; the arc-shaped plate and the side supporting plates are made of composite materials, and the arc-shaped plate and the side supporting plates are integrally formed; the arc-shaped plate is used for being connected with the lower portion of a fuselage of an aircraft, and the two side supporting plates are connected to the two end faces of the arc-shaped plate respectively and used for being connected with two hubs respectively. The problems that in the prior art, a main lifting support is made of a metalmaterial, and the overall weight is large; and two hydraulic rods and a hub supporting mode are adopted, the weight of a main lifting support is large, operation is strenuous, and the universality ispoor are solved. The arc-shaped plate and the side support plates are made of composite materials, so that the overall weight is light; the two ends of the arc-shaped plate are each connected with onecorresponding side supporting plate, each side supporting plate is connected with a corresponding hub, and the whole support is light in weight and good in universality.

Description

technical field [0001] The invention relates to the technical field of aviation aircraft accessories, in particular to a composite material main lifting bracket and a manufacturing and assembling method thereof. Background technique [0002] The main landing gear is an accessory device at the lower part of the aircraft used to take off, land, support the aircraft when taxiing on the ground, and move on the ground. It is an indispensable part of the aircraft. In the process of safe take-off and landing of aviation aircraft, it shoulders an extremely important mission. [0003] In the prior art, the main landing gear adopts the structure of hydraulic rods, that is, two hydraulic rods are used, the upper ends of the two hydraulic rods are connected to the lower part of the fuselage of the aircraft, and the lower ends of the two hydraulic rods are respectively connected to the left wheel hub and the right wheel hub. . The use of two hydraulic rods not only supports the body of...
