<p>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</p> |
