我国货车制动系统存在的问题及展望(待续)

Problems Existing in the Braking System on Freight Cars in Our Country and the Prospects(To Be Continued)

概述了我国货车制动装置的现状。根据货物列车提速和重载化的发展要求 ,阐述了现有货车制动装置存在的问题。从制动能力、轮轨粘着利用、制动热负荷和列车纵向力等不同方面 。

The present state of freight car braking equipment in our country is described generally. According to the development requirements of speed increase and heavy haul of freight trains, the problems existing in the present freight car braking equipment are expounded. The development orientation of the freight car braking equipment is explained through the quantitative calculation and theoretical analysis mainly from such aspects as braking capacity, wheel rail adhesion application, braking heat load and longitudinal force of the train.
