Locomotive Leaf Spring Specifications:
Multi-leaf spring: It consists of multiple steel sheets with different lengths and the same width. The steel plates of multiple leaf springs are superimposed into an inverted triangle shape. The uppermost steel plate is the longest, and the lowermost steel plate is the shortest. The more steel plates, the thicker and shorter, the greater the spring rigidity.
Few leaf springs: superimposed by steel sheets with thin ends and thick middle, equal width and equal length.
Compared with the multi-leaf spring, the less-leaf spring is about 50% lighter than the multi-leaf spring under the same stiffness (that is, the same load capacity), which reduces fuel consumption and increases driving comfort. Moreover, the single leaf of the few leaf springs are in point contact, which reduces relative friction and vibration and increases the comfort of passengers.
