[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS: The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0015] The operating principle of the buffer of the present invention is:
[0016] Elongation energy absorption: when the buffer is elongated, the volume of oil chamber 1A decreases, the oil in chamber A pushes away from the valve 14 at high speed and flows into oil chamber 2B through the positive damping hole a on the damping plate 13, and the oil in chamber B increases , pushing the isolation piston 16 to move downward, forcing the volume of the air chamber C to decrease and the pressure to increase. During this process, the buffer converts the kinetic energy of the helicopter into the kinetic energy of the oil and the elastic potential energy of the gas, while the high-speed flowing oil rubs against the positive damping hole a on the damping plate 13 to generate heat, and finally passes through the inner a...
