Embodiment Construction

[0018] Attached below figure 1 , 2 , 3, 4, 5 describe the present invention in detail:

[0019] A semi-concealed elevator rocker arm, the rocker arm body 3 is located between the right rudder surface 1 and the left rudder surface 2, and the rocker arm body 3 passes through the ear piece of the right joint 4 in the right rudder surface 1 and the middle of the left rudder surface 2 The lugs of the left connector 5 are connected together;

[0020] The rocker arm main body 3 is in an "S" shape, and the rocker arm main body 3 is connected to the flat tail joint 8 through the flat tail joint bolt 6; it is designed in an "S" shape to ensure a reasonable gap with the surrounding structure when it moves.

[0021] The rocker arm main body 3 is connected with the steering pull rod through the steering connecting bolt 7 .

[0022] The rocker arm body 3 is provided with bolts I9 and bolts II10. It is used to connect the right joint and the left joint.

[0023] Round holes 11 are p...

Abstract

The invention relates to a half hidden type elevating rudder rocker arm, and belongs to the technical field of control surface structures of airplane tail wings. A rocker arm main body is positioned between a right control surface and a left control surface, the rocker arm main body is connected with an ear piece of a left joint in the left control surface through an ear piece of a right joint in the right control surface; the rocker arm main body is 'S'-shaped; the rocker arm main body is connected to a horizontal tail joint through a horizontal tail joint bolt; the rocker arm main body is connected with a control operating rod through a control connecting bolt. The structural style of the rocker arm has the advantages that aiming at the characteristic that the structure space of a light aeroplane is small, the structural style of the elevating rudder control rocker arm is improved, a traditional torque tube structure is cancelled, the conventional structure is fully used, the left control surface and the right control surface are integrally and directly connected with the rocker arm through the two symmetrical joints. The elevating rudder adopting the structural style is good in integrality, the rocker arm is half hidden type, only part of the control ear pieces is exposed, the force transmission path is short, the crossbeam directly participates in load carrying, the assembly parts are reduced, and the joint bolts of the left control surface and the right control surface are simplified as two.

Description

technical field [0001] The invention relates to a semi-concealed elevator rocker arm, which belongs to the technical field of control surface structures of aircraft empennages. Background technique [0002] The control rocker arm of the empennage control surface is usually designed to be connected with the structural torsion tube, which requires a large installation space. The traditional control rocker arm is divided into double-arm type and single-arm type according to the different control transmission forms. Both of them generally need to be connected with the torque tube at the rotating shaft of the control surface through a flange. The rocker arm of this structure has a certain distance from the main structure of the control surface, requiring a large layout space for the structure. Therefore, in the control surface structure of some small aircraft, the space condition is limited, and it is necessary to improve the rocker arm structure and its assembly conditions, mak...
