摘要： An underframe arrangement for a railway vehicle and including a deep section center sill joined to a draft sill portion through use of a transition beam member. Both the transition beam member and the draft sill have overlapping flange portions in the area adjacent the car body bolster and center filler. Overlapping these flange portions increases the strength of the draft sill to transition sill connection to resist buff and draft forces by directing these longitudinal forces into the bottom web of the draft sill and transition sill and from there through the transition section and into the deep section center sill which is capable of absorbing and dissipating large longitudinal loads. The overlapping members also increase the strength of the center filler area to provide an improved bolster.
摘要翻译：一种用于铁路车辆的底架布置，并且包括通过使用过渡梁构件而与接地部分接合的深部中心梁。过渡梁构件和挡风板在邻近轿厢主体和中心填料的区域中具有重叠的凸缘部分。将这些凸缘部分重叠，通过将这些纵向力引导到通式和过渡台架的底部腹板中，并从那里通过过渡部分并进入深部中心能够吸收和消散大纵向载荷的门槛。重叠构件还增加了中心填充区的强度，以提供改进的垫块。
