摘要： Bottom discharge hopper rail cars generally have a chassis on flanged wheels, and a hopper body mounted on the chassis and including transversely and longitudinally extending edges which border a discharge opening from the body. In the present invention, the opening is wholly or substantially wholly at a level below the tops of the wheels but above the bottoms of the wheels and extends at least partly between pairs of said flanged wheels.

摘要： A bottom discharge hopper rail car train includes a pair of hopper rail cars each having a hopper body mounted on a chassis. Adjacent ends of the two hopper rail cars are supported by a split bogie assembly having bogie parts each pivotally mounted at an end region of a respective rail car and each including a pair of flanged wheels rotatable about a common axis. In this invention, the bogie parts are mounted adjacent to one another and each have formations for co-operating with complementary formations on the other bogie part for co-operating movement of the bogie parts of the assembly with respect to one another when the assembly moves along a curved track. The invention also extends to a split bogie assembly.
摘要翻译：底部卸料斗轨道车列车包括一对料斗轨道车，每个料斗轨道车厢均安装在底盘上。两个料斗轨道车厢的相邻端部由分体转向架组件支撑，该转向架组件具有转向架部件，每个转向架部件可枢转地安装在相应的轨道车厢的端部区域，并且每个转向架部件包括可绕公共轴线旋转的一对凸缘轮。在本发明中，转向架部件彼此相邻地安装，并且每个都具有用于与另一个转向架部件上的互补结构配合的结构，用于当组件移动时使组件的转向架部件相对于彼此协调运动沿着弯曲的轨道。本发明还延伸到分离转向架组件。
