钩缓装置50年的回顾与展望

Review and Prospects of the Draft Gears in the Recent 50 Years

为适应我国铁路运输的持续发展,通过50年来的不断科技创新,钩缓装置由新中国成立初期的低等级、单形式向高等级、多品种、系列化演变,目前形成了自主知识产权的客车、货车、机车、城轨及地铁车辆用系列钩缓装置,其部分技术已达到了国际先进或领先水平。展望未来,随着国内外市场需求的不断变化和提高,预计我国钩缓技术和装备仍有较大的发展空间。

In order to adapt to the continuous development of railway transport in China,through constant scientific and technological innovation in the recent 50years,the draft gears have evolved from the low grade and single type at the beginning of founding of P.R.China to the high grade,many types and being in series.The series of draft gears with our own intellectual properties for passenger cars,freight cars,locomotives,urban rail vehicles and metro cars have been completed at present,and some of the technologies have reached internationally advanced or leading level.Looking forward to the future,along with the continuous changes and improvements of the market demand in China and abroad,we think that there shall be still great space to develop technologies and equipment of draft gears in China.
