国内最高速的悬挂式单轨列车日前在中车四方下线,进入型式试验和试运行阶段,其设计时速为80公里,最高运行时速为70公里。
Chinese rail car manufacturer CRRC Qingdao Sifang has unveiled a prototype of a mounted monorail train with a maximum operating speed of 70 kilometers per hour, the fastest of its kind in China.
国内最高速的悬挂式单轨列车日前在青岛中车四方下线,最高运行时速为70公里。
悬挂式单轨列车(mounted monorail train),又被称为空轨或空中列车(sky train),是一种轻型、中速、中运量、低成本的新型公共交通方式(new mode of transportation featuring light weight, moderate speed, medium capacity and low manufacturing cost)。
这款悬挂式单轨车辆爬坡能力强(strong climbing ability),最大爬坡能力达到100‰(列车前行1000米后高度上升100米),是普通地铁车辆爬坡能力三倍以上,可在地形崎岖陡峭的山区灵活运行,并保证具有较高安全性和舒适度,载客量(passenger capacity)可达到300至510余人。
悬挂式单轨列车的轨道在车的正上方,行驶中既不受雨雪天气影响,也不会有脱轨风险,列车有多种主被动安全装置,如全车监控系统(whole-train monitoring system)、蓄电池救援(battery rescue)和联挂救援(coupling rescue)等。
另外,悬挂式单轨列车轨道曲线半径小,占用地面空间少,拆迁工程量可显著降低,节约成本投入,仅为地铁成本的三分之一。相对于地面有轨电车(tram),悬挂车避开了与地面车辆混行问题,具有安全、准点、载客能力强等优势(advantage of safety, punctuality and high passenger capacity)。
除了悬挂式单轨,我国还有很多科幻般的交通工具:
跨座式单轨列车(straddle-beam monorail line),这是重庆自主研发的跨座式单轨交通系统。与常见的双轨式轨道交通不同,跨座式单轨交通是轨道为一条带形梁体,车辆跨坐于其上行驶的交通系统。新一代跨座式单轨车辆能够配置无人驾驶系统,实现列车自动唤醒、自动出库并上线运行,全天运行结束后自动返回停车段。
无轨列车(virtual rail line),6月2日,全球首列虚拟轨道列车在湖南株洲惊艳亮相。这款被命名为“智能轨道快运系统”(Autonomous rail Rapid Transit,简称智轨)的全新交通产品,融合了现代有轨电车和公交客车的优势,既可以作为立体化交通解决方案的补充,也能够担当区域交通线路的骨干。
