Railway vehicle buffer for reducing longitudinal impact of train

Abstract

The invention railway vehicle buffer capable of reducing the longitudinal impact of the train comprises a first main buffer cylinder, a second main buffer cylinder, a buffer frame main body, a connecting frame and a nut, wherein the second main buffer cylinder is installed at one end of the first main buffer cylinder, and the buffer frame main body is installed at the end, away from the first mainbuffer cylinder, of the second main buffer cylinder; elastic rubber is installed on the two sides of the interior of the buffering frame body, a first auxiliary buffering cylinder is installed on theouter wall of one side of the buffering frame body, a second auxiliary buffering cylinder is installed at the end, away from the buffering frame body, of the first auxiliary buffering cylinder, and alimiting structure is arranged at the end, away from the first auxiliary buffering cylinder, of the second auxiliary buffering cylinder. According to the buffer, convenience of the buffer during installation and maintenance is enhanced, the buffer performance of the buffer is improved, the function of multi-stage train longitudinal impact reduction of the buffer is achieved, and use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of buffers, in particular to a buffer for railway vehicles that reduces the longitudinal impact of trains. Background technique [0002] Compared with general-purpose trucks, the speed of express trucks with a running speed of 160km / h to 200km / h has been significantly improved, and higher requirements are placed on safety and stability. As an important part of railway vehicles, buffers play a role The longitudinal impact of the train and the function of absorbing the energy of the train are of great significance to reduce the longitudinal impulse of the train, improve the stability of the train operation, and protect the safety of the transported goods. [0003] There are a great variety of such buffers for railway vehicles on the market today, which can basically meet people's needs for use, but there are still certain deficiencies, and the specific problems have the following points. [0004] (1) The rela...
