跨坐式单轨车辆落架装置的研发与应用

Development and Application of Undercarriage Apparatus in Straddle Monorail Vehicle

跨坐式单轨车辆与传统的钢轮钢轨地铁车辆相比,在走行、导向机构等方面有较大差异。针对PBTS跨坐式单轨车辆单轴转向架的结构特点,结合其在整车制造、车辆临修和大修过程中的技术需求,对转向架快速拆卸方案进行研究,设计制作了一种新型的落架装置。该装置可实现单轨车辆在轨道梁上快速更换转向架、换轮的操作。通过该落架装置的使用,更换走行轮作业可节约65%的工时,更换导向轮作业可节约85%的工时,显著提高了转向架的维护效率。

Compared with traditional metro vehicles with steel wheel and rail,the straddle monorail vehicle has bigger difference in aspects like running and guiding mechanism.According to the single axle bogie structural characteristics of PTBS straddle monorail vehicle,a rapid bogie undercarriage scheme is designed and developed in combination with the technical demands for monorail vehicle in production process,temporary repair and overhaul.On this basis,a new undercarriage apparatus is designed,which could realize rapid replacement of monorail vehicle bogie and whee on the runway track.Application practice shows that the new device can save more than 65%the time in wheel replacement,and 85%the time in guide wheel replacement,thus significantly improve the efficiency of vehicle bogie maintenance.
