Embodiment Construction

[0029] In order to make the object, technical solution and effect of the present invention clearer and clearer, the following examples are given to further describe the present invention in detail. It should be pointed out that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0030] Such as figure 1 As shown, the auxiliary driving device for folding wings proposed by the present invention mainly includes a transmission device for converting rotary motion and linear motion and a solid-liquid mixed spring for energy storage, and also includes connecting parts with the inner wing and the shaft. mechanical device.

[0031] The working method of the folding wing auxiliary driving device of the present invention:

[0032] When the wings are unfolded, gravity does work, and the main drive works to provide the wings with a moment to overcome the gravity, and the external force distributed to the auxilia...

Abstract

The invention discloses a solid and liquid mixed spring-based auxiliary driving device for folding wings, and belongs to the technical field of aviation structures. The auxiliary driving device comprises a transmission device and a solid and liquid mixed spring mechanism, wherein the solid and liquid mixed spring mechanism comprises a main hydraulic cylinder and a plurality of shunting hydraulic cylinders which are connected with the main hydraulic cylinder through oil delivery pipes. The auxiliary driving device for the folding wings is capable of storing the power of external force when thewings are unfolded, and releasing the power when the wings are folded so as to provide a part of driving force to assist a main driver, thereby decreasing the demand for the driving ability of the main driver; and the energy is stored by adoption of the solid and liquid mixed spring, the force and displacement stroke are transferred through the hydraulic cylinders, and the springs are placed at any positions, insensitive to the weight and space size, in the wings, so that the limiting problems, for the space size and weight, of the wing types are solved.

Description

technical field [0001] The invention belongs to the field of aeronautical structure design, and in particular relates to an auxiliary driving device for folding wings based on a solid-liquid mixed spring. Background technique [0002] The wing folding technology can save the space occupied by the deck when the carrier-based aircraft is parked, and can also fold the wings during flight to increase the flight stability. The driving device plays an important role in the process of wing folding and unfolding, and it is necessary to select a suitable driving device according to the specific load requirements and installation space. At present, the driving devices of folding wings mainly include the following types: electric motor drive, pneumatic / hydraulic drive and hybrid drive, and the drive is equipped according to the specific load situation; but when the load is relatively large, the size of the drive needs to be increased and the space occupied And the weight is relatively...
