实现铁路运输高速、重载的目标,车辆制动技术是关键环节之一,本文介绍了绝大多数货车采用人工手动调整,往往疏漏未调,因而研制出了货车空重车自动调整装置。这对我国铁路货车的提速和重载列车的发展及要求制动装置性能的提高有着重大的意义。 To achieve the goal of high-speed and heavy-haul railway transportation, vehicle braking technology is one of the key aspects. This paper introduces the vast majority of trucks using manual manual adjustment, often omission, thus developed a truck empty and heavy truck automatic adjustment device. This is of great significance to the development of China’s railway freight cars for speeding up and heavy-haul trains and the improvement of the performance of brake devices.
