Self-adaptive landing gear

Abstract

The invention provides a self-adaptive landing gear, and belongs to the design field of helicopter landing gear structure. The landing gear comprises a first buffer, a second buffer, a rocker arm, andan actuating cylinder, wherein one end of the first buffer is connected to a machine body and the other end of the first buffer is hinged on the rocker arm, one end of the rocker arm is hinged with one end of the actuating cylinder, the other end of the rocker arm is hinged on the machine body, the other end of the actuating cylinder is connected to a machine wheel axle, one end of the second buffer is hinged on the actuating cylinder, and the other end of the second buffer is hinged to the rocker arm. The landing gear disclosed by the invention has strong adaptability to complex terrains, has a dynamic balance control capability, and can maintain a machine body balance within a large angle range under the self-adaptive working mode. The self-adaptive working mode can replace the functions of a harpoon, thereby being capable of reducing the weight of a helicopter structure on the other hand, and a shipboard does not need to assist the descending of grids.

Description

technical field [0001] The invention belongs to the field of helicopter landing gear structure design, and in particular relates to an adaptive landing gear. Background technique [0002] In addition to the functions of the traditional landing gear, the adaptive landing gear provides the landing ability of the helicopter on uneven ground (including slopes and steps, etc.) through the joint control of the robot legs, and has the ability to maintain the balance of the body on the shaking platform. Adaptability of the helicopter to the landing site. Take the patent "adaptive all-terrain helicopter landing gear device" (application number: CN201210464093.4) ​​as an example, it compares the feedback information of the distance sensor with the reference distance, drives the actuator to reach the reference distance before landing, and achieves all-terrain adaptive the goal of. This invention has the following problems: it can be adjusted in place before landing, and it cannot be ...
