    • A railcar bogie plate spring of the present invention includes: an upper surface member constituted by fiber reinforced plastic in which reinforced fibers are stacked so as to extend in a longitudinal direction; a lower surface member constituted by fiber reinforced plastic in which reinforced fibers are stacked so as to extend in the longitudinal direction; and a core member arranged between the upper surface member and the lower surface member. The core member is constituted by fiber reinforced plastic in which: reinforced fibers are stacked in a width direction perpendicular to a stack direction of the upper surface member and the lower surface member; and in a side view of the core member, the reinforced fibers are inclined relative to a bending neutral axis so as to intersect with one another.
    • 本发明的轨道车转向架板簧包括:由纤维增强塑料构成的上表面构件,其中增强纤维沿长度方向堆叠, 由纤维增强塑料构成的下表面构件,其中增强纤维被堆叠成在纵向上延伸; 以及设置在上表面构件和下表面构件之间的芯构件。 芯构件由纤维增强塑料构成,其中:在与上表面构件和下表面构件的堆叠方向垂直的宽度方向上堆叠增强纤维; 并且在芯构件的侧视图中,增强纤维相对于弯曲中性轴线倾斜,以便彼此相交。

    • A bogie designed to be secured so that it rests on wheels and including at least two wheel axles, at least one side member extending from the axles to an at least approximately central part of the length of the bogie, and axle boxes in which the axles are mounted so that they can rotae. The side member includes at least one interchangeable elastic leaf constituting parametrizable primary suspension, made of composite material based on fibers embedded in a resin, and a region of each end of the side member is housed in a side-member sleeve resting on a respective axle box via at least one insert element.
    • 转向架被设计成被固定,使得其位于车轮上并且包括至少两个轮轴,至少一个从轴延伸到转向架长度的至少大致中心部分的侧构件,以及轴箱,其中轴 被安装成可以旋转。 侧构件包括构成可参数的初级悬浮液的至少一个可互换弹性叶片,由基于嵌入树脂中的纤维的复合材料制成,并且侧构件的每个端部的区域容纳在搁置在相应的轴上的侧构件套筒中 盒通过至少一个插入元件。
