Three-stage buffer with piston movement adjusted by processor according to impact pressure

Abstract

The invention relates to a three-stage buffer with piston movement adjusted by a processor according to impact pressure. The three-stage buffer is composed of a front-stage buffer body, a middle-stage buffer body and a tail-stage buffer body. The buffer bodies each comprise a cylindrical cylinder body filled with a buffer medium, cylinder covers are arranged at the opening ends of the cylinder bodies in a sealed manner, piston rods are in sealed movable fit with center through holes of the cylinder covers, and piston body assemblies are arranged at the right ends of the piston rods, are suitable for conducting piston movement in the cylinder bodies and are in movable sealed fit with the inner walls of the cylinder bodies. The cylinder body of the front-stage buffer body serves as the piston rod of the middle-stage buffer body and the cylinder body of the middle-stage buffer body serves as the piston rod of the tail-stage buffer body. A pressure sensor used for detecting the pressure of the medium is arranged on the right end face of the piston body assembly of the middle-stage buffer body. The piston body assemblies of all the buffer bodies are suitable for adjusting the reciprocating flow of the medium in the corresponding cylinder bodies in the piston movement process according to the medium pressure detected by the pressure sensor, so that the moving speeds of pistons are controlled.

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...
