A railway car buffer for reducing the longitudinal impact of trains

Abstract

The invention discloses a railway vehicle buffer for reducing the longitudinal impact of trains, which comprises a first main buffer cylinder, a second main buffer cylinder, a buffer frame main body, a connecting frame and nuts, one end of the first main buffer cylinder is installed with a second Two main buffer cylinders, and the end of the second main buffer cylinder away from the first main buffer cylinder is equipped with a buffer frame main body, and both sides of the buffer frame main body are installed with elastic rubber, and the outer wall of the buffer frame main body is installed There is a first auxiliary buffer cylinder, and the end of the first auxiliary buffer cylinder away from the main body of the buffer frame is installed with a second auxiliary buffer cylinder, and the end of the second auxiliary buffer cylinder away from the first auxiliary buffer cylinder is provided with a limiting structure. The invention not only enhances the convenience of installation and maintenance of the buffer, improves the buffer performance of the buffer, but also realizes the multi-stage function of the buffer to reduce the longitudinal impact of the train and reduces its use cost.

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...
