一、前言随着牵引吨位的增加,高速列车的出现,我国机、货车现用的二、三号缓冲器性能不能满足要求,迫切需要新型缓冲器来代替。MX—1型缓冲器开始设计试制于1968年,后经几次修改,并先后试制了近百套,通过各种试验和经过两年的运用考验,证明性能良好,基本上达到了设计要求。 I. INTRODUCTION With the increase of traction tonnage and the emergence of high-speed trains, the performance of the current No. 2 and No. 3 bumpers used in China’s machine and truck can not meet the requirements, and a new type of bumper is urgently needed instead. MX-1-type buffer began to design trial in 1968, after several changes, and has trial production of nearly 100 sets, through a variety of tests and after two years of use test to prove good performance, basically reached the design requirements.
