Dual-voltage driven and controlled buffer with atomized oil cavity loop

Abstract

The invention relates to a flight buffer, in particular to a dual-voltage driven and controlled buffer with an atomized oil cavity loop. An oil outlet is arranged on a buffer piston rod; the oil outlet of the piston rod is connected with the oil inlet of a second high-speed unidirectional switch valve bank through an oil pipeline; the oil outlet of the second high-speed unidirectional switch valve bank is connected with the oil inlet of an external oil cavity through the oil pipeline; the oil outlet of the external oil cavity is connected with the oil inlet of a first high-speed unidirectional switch valve bank through the oil pipeline; and the oil outlet of the first high-speed unidirectional switch valve bank is connected with the oil inlet on the side wall of an outer cylinder through the oil pipeline. The main body of the dual-voltage driven and controlled buffer with an atomized oil cavity loop provided by the invention comprises an inner cylinder and an outer cylinder and is not provided with oil holes, oil needles and other oil quantity regulating components, thus the structure is simple. Double voltages are used for driving and controlling high-speed switch valves to be opened or closed, thereby increasing the response speed of the high-speed switch valves.

Description

technical field [0001] The invention relates to a flight buffer, in particular to a dual-voltage drive control buffer with an atomized oil cavity circuit. Background technique [0002] Aircraft landing gear buffer is a device in the landing gear that absorbs the impact and turbulence energy of the aircraft landing and ground movement, and acts as a buffer and shock absorber. comfort. [0003] In order to enhance the cushioning effect of the buffer, three control technologies, passive control, semi-active control and active control, have been applied in the performance control of the buffer. The passive control buffer uses the buffer itself to control the opening of the oil hole and adjust the damping. Its structure is simple, but because its system structure and parameters are fixed, once it is manufactured and installed, its work is a passive response to external excitation It is difficult to meet the needs of efficient shock absorption by changing its own characteristics...

AI Technical Summary

Problems solved by technology

However, due to space constraints, the two cavities of the buffer should not be too large, and the oil will be heated up rapidly in the cavities, which will affect the thermal diffusion rate, thereby affecting the buffering efficiency
