Problems solved by technology

[0002] The existing buffer, which is a two-stage buffer, controls the action sequence of the first-stage buffer and the secondary buffer through the difference between the maximum force of the medium and the initial minimum force in the first-stage buffer and the secondary buffer; In actual work, since the impact energy is not constant and may change, it is difficult to realize the working order of buffers at all levels depending on the medium.

Abstract

The invention relates to an operating method of a buffer. The bumper consists of a first-stage buffer, a transtage buffer and a final-stage buffer, each of which comprises a cylindrical cylinder body used for filling a buffering medium, wherein a cylinder cover is arranged at the open end of each cylinder body in a sealing manner, a piston rod is sealed in the central through hole of the cylinder cover in a movably matched manner, and a piston body component is arranged at the right end of the piston rod, is suitable for conducting piston motion in the cylinder body and is movably sealed fit with the inner wall of the cylinder body; the cylinder body of the first-stage buffer forms a piston rod of the transtage buffer, and the cylinder body of the transtage buffer forms a piston rod of the final-stage buffer; a pressure sensor used for detecting the medium pressure is arranged on the right end surface of the piston body component of the transtage buffer; the piston body components of the three buffers are suitable for adjusting the reciprocating flow rates of media in the corresponding cylinder bodies according to the medium pressure detected by the pressure sensor during piston motion so as to control the piston motion rates.

Description

technical field [0001] The invention relates to a working method of a buffer, in particular to a working method of a buffer using elastic colloid as a buffering medium. Background technique [0002] The existing buffer, which is a two-stage buffer, controls the action sequence of the first-stage buffer and the secondary buffer through the difference between the maximum force of the medium and the initial minimum force in the first-stage buffer and the secondary buffer; In actual work, since the impact energy is not constant and may change, it is difficult to realize the working sequence of the buffers at all levels depending on the medium. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a working method of the shock absorber that adjusts the piston movement according to the impact pressure. The working method solves the technical problem of matching the piston movement and the impact energy due to the change of t...
