    • The invention relates to a leaf spring (1), especially for rail vehicles, comprising an inner (2) and an outer connecting part (4) and at least two spring layers that are located therebetween and are made alternately of one elastomeric layer (9, 10, 11, 12) and a sheet metal layer (5, 6, 7, 8). The elastomeric layers are vulcanized together with the connecting parts and the sheet metal layers while being provided with different thicknesses. Each elastomeric layer is made of the same material. The inventive leaf spring further comprises a substantially conically contoured support disk (14) that is placed above the thickest spring layer in the direction in which stress is applied. The inner portion of the softest layer initially rests on the support disk when the spring is loaded while the outer portions of the softest layer, followed by the other spring layers, also rest on the support disk in a continually increasing manner as the load augments. The contour of the support disk influences the characteristic curve of the spring. ® KIPO & WIPO 2008
    • 本发明涉及一种特别用于轨道车辆的板簧(1),其包括内部(2)和外部连接部分(4),以及至少两个弹簧层,其位于它们之间并且交替地由一个弹性体层(9 ,10,11,12)和钣金层(5,6,7,8)。 弹性体层与连接部件和金属板层一起硫化,同时提供不同的厚度。 每个弹性层由相同的材料制成。 本发明的板簧进一步包括基本上圆锥形的支撑盘(14),其被放置在施加应力的方向上的最厚的弹簧层的上方。 当加载弹簧时,最软层的内部部分最初搁置在支撑盘上,而最软层的外部部分以及随后的其它弹簧层也以负载增加的方式以不断增加的方式搁置在支撑盘上。 支撑盘的轮廓影响弹簧的特性曲线。 ®KIPO&WIPO 2008
