Description

Double-intersection-point flap slide rail trailing edge suspension joint

Technical Field

The utility model belongs to the technical field of two intersection point trailing edges hang and connect, a two intersection point flap slide rail trailing edges hang and connect is related to.

Background

The analysis of the movable airfoil surface suspension joint in the multi-model trailing edge cabin at home and abroad shows that: such concentrated load joints are all single point joints. At present, an embedded flap motion mechanism is required to be adopted for an airplane, and the upper intersection point and the lower intersection point of a flap slide rail are both positioned in a trailing edge cabin, so that a double-intersection-point joint needs to be designed.

Disclosure of Invention

The utility model aims at: in order to solve the technical problem, a double-intersection flap slide rail trailing edge suspension joint is designed.

The technical scheme of the utility model: a double intersection point flap track trailing edge suspension joint, comprising: a joint body 1, a bush 2; the joint body 1 is of a double-intersection-point single-lug structure and comprises a web plate and a flange strip, the double intersections are located on the web plate and matched with upper and lower intersection points of a flap slide rail, and the two bushings 2 are arranged in the double intersections of the joint body 1.

The two intersection points are two earholes of the joint body 1.

The bush 2 is pressed in the earhole of the joint body 1.

The trailing edge suspension joint of the double-intersection-point flap slide rail is matched with the flap slide rail through a single lug and a double lug and is connected with the flap slide rail through a bolt.

And the course edge strip on one side of the intersection point on the suspension joint at the rear edge of the double-intersection-point flap slide rail is connected with the upper wall plate of the box section through a high-lock bolt.

And the course edge strip on one side of the lower intersection point of the rear edge suspension joint of the double-intersection-point flap slide rail is connected with the lower wall plate of the box section through a high-lock bolt.

The utility model has the advantages that:

1) easy to detach and mount the flap

2) Without destroying the seal of the wing tank

3) The wing flap slide rail and other motion mechanisms are positioned in the wing profile, and the wing flap slide rail fairing does not need to be additionally arranged

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, a trailing edge suspension joint of a double intersection point flap slide rail comprises: a joint body 1, a bush 2; the joint body 1 is of a double-intersection single-lug structure and comprises a web plate and a flange strip, the double-intersection is positioned on the web plate and matched with the upper and lower intersection points of the flap slide rail, and the two bushings 2 are arranged in the double-intersection point of the joint body 1; the double intersection points are two ear holes of the joint body 1; the bush 2 is pressed in the earhole of the joint body 1; the trailing edge suspension joint of the double-intersection-point flap slide rail is matched with the flap slide rail in a single-lug and double-lug mode and is connected with the flap slide rail through a bolt; the course edge strip on one side of the intersection point on the suspension joint at the rear edge of the double-intersection-point flap slide rail is connected with the upper wall plate of the box section through a high-lock bolt; the course edge strip on one side of the lower intersection point of the rear edge suspension joint of the double-intersection-point flap slide rail is connected with the lower wall plate of the box section through a high-lock bolt;

the double-intersection-point wing flap slide rail trailing edge suspension joint is designed into an integral structure, has good integrity, is connected with a wing flap slide rail through an upper intersection point and a lower intersection point, is simple and convenient to disassemble and install, and well realizes the diffusion of the wing flap lift force to a wing box section.
