A two-stage buffer suitable for realizing uniform buffering at all levels

Abstract

The invention relates to a two-stage buffer capable of realizing uniform buffering of both stages. The two-stage buffer comprises a first stage buffer part and a final stage buffer part, wherein each of the first stage buffer part and the final stage buffer part comprises a columniform cylinder body; cylinder covers are arranged at open ends of the cylinder bodies in a sealing manner; a piston rod is movably matched with a center through hole of each cylinder cover; piston body components are arranged at the right ends of the piston rods; the piston body components can make piston motion in the cylinder bodies, and are movably matched with inner walls of the cylinder bodies in a sealing manner; the cylinder body of the first stage buffer part forms the piston rod of the final stage buffer part; a pressure sensor for detecting medium pressure is arranged on the right end surface of the piston body component of the first stage buffer part; and the piston body components of both the buffer parts can adjust the medium traffic flows in the corresponding cylinder bodies according to the medium pressure detected by the pressure sensor to control the speed of the piston motion during the piston motion.

Description

technical field [0001] The invention relates to a buffer, in particular to a buffer using elastic colloid as a buffer medium. Background technique [0002] In the field of cushioning and shock absorption, buffers are widely used, and their main functions are to absorb various impact energy, protect equipment and reduce noise. [0003] The authorization number CN202149175 discloses a buffer, which is a two-stage buffer, and the maximum force F1max and the initial minimum force F2cmin of the medium in the first-stage buffer and the secondary buffer are different to control the first-stage buffer and the secondary buffer. The action sequence of the buffer; and it is mentioned in the manual that the capacity of the entire buffer is set according to the impact energy. However, in real work, because the impact energy is not constant, it may change, so it depends on the medium. Realizing the working order of buffers at all levels is difficult to realize in practice.
