半挂列车现已成为中长途物流运输的重要车型之一。随着全国高速公路网的建设,以及道路运输条件的改善,半挂列车的使用将会得到更加快速的发展。甩挂运输(即一辆牵引车配备多辆挂车在工作区间内轮流进行拖挂运输)在国外早已得到普遍应用,不但提高了运输效率,也极大地节约了运输成本。但是,我国挂车技术水平较低,甩挂运输起步较晚,半挂列车事故率较高,尤其半挂列车制动性能检测及使用维护中尚存在一些问题,这些都严重制约着半挂列车的健康发展。下面笔者浅谈半挂列车制动性能检测及其使用维护
Semi-trailer train has now become one of the important models in the long-distance transport logistics. With the construction of the national highway network and the improvement of road transport conditions, the use of semi-trailer train will be more rapid development. Thruster transport (that is, a tractor equipped with multiple trailers in the work area in turn for trailer transport) has long been widely used abroad, not only to improve the transport efficiency, but also greatly save on transport costs. However, the technical level of the trailer in our country is relatively low, the sluggish transport starts later and the semitrailer train accident rate is higher. In particular, there are still some problems in the testing and maintenance of semitrailer braking performance, which severely restrict the semi-trains healthy growth. The following talk about the semitrailer brake performance testing and maintenance
