Abstract

The invention aims to provide a cabin door driving assembly, an undercarriage cabin door assembly and a cabin door driving assembly design method. In order to achieve the purpose, the cabin door driving assembly comprises an actuating unit and a pair of pull rods, the actuating unit comprises a rod piece capable of conducting linear displacement, one end of each pull rod is connected with the end of the rod piece in a relative rotation mode, and the other end of each pull rod is used for being connected with the cabin door. The cabin door driving assembly with the structure is simple in structure and easy to implement and assemble. Meanwhile, compared with the mode that a plurality of connecting points are arranged in an existing cabin door driving assembly, the number of the connecting points in the cabin door driving assembly recorded according to the application is small, and compared with an existing scheme, the later damage probability of the cabin door driving assembly is lower, so that the maintenance cost can be reduced.

Description

Technical field [0001] The present invention relates to the field of aircraft, in particular to a hatch-drive assembly, a landing gear hatch assembly, and a hatch-door drive assembly design method. Background technique [0002] Aircraft's landing gear door requires a driver assembly driver to perform synchronization opening, such as figure 1 A schematic diagram showing an existing landing gear, including a hatching cylinder 90, a rocker arm 91, and a two trip rod 92. Among them, the hatch is hinged from the rocker arm 91, and the rocker arm 91 is rotatable about the first point 93, and the two pull rods 92 are hinged from the rocker arm 91, respectively, and the other end is connected. [0003] When actuation is actuated as the driver 90, the piston rod 901 in the actuator 90 can extend or retraction to the cylinder of the actuator, and rotate about the first point 93. When the rocker arm 91 is rotated about the first point 93, the two lever 92 can be driven separately, so that t...
