美国 Aeronca 制造公司为南方铁路设计制造了一种四节漏斗车(图1)。该车的设计主要是参考了飞机结构的设计,将有关飞机框架结构的一些技术广泛应用到车辆的设计中来。图1 四节漏斗车的外形南方铁路在1960年开始用漏斗车组成的列车运煤,当时设计的是89吨的铝制漏斗车,本文所述的四节漏斗车的基本设计方案就是用两节两轴车来代替原用的一辆89吨漏斗车。采用两轴车设计的优点在于用一节两轴车就可以装运58吨煤,四节车可以装载232吨。对于漏斗车,在转向架上面的空间是不容易得到利用的。因为车体两端的地板必须 Aeronca Manufacturing Company of America designed and manufactured a four-hopper car for the Southern Railway (Figure 1). The design of the car mainly refers to the design of the aircraft structure, some of the technologies related to the aircraft frame structure are widely used in the design of the vehicle. Figure 1 four hopper car appearance Southern Railway in 1960 began to use the funnel car train coal, was designed to 89 tons of aluminum funnel car, four-hopper car described in this article is the basic design of the two Two-axle car to replace the original one 89 tons hopper car. Advantages of using two-axle car design is that with a two-axle car can be transported 58 tons of coal, four car can load 232 tons. For hopper cars, the space above the bogie is not readily available. Because the floor at both ends of the body must
