Leaf-spring assemblies

Leaf-spring assembly, comprising:

• a main spring leaf having an integrally formed spring eye;
• a supporting spring leaf which is beneath said main spring leaf, is approximately the same length and has at one end a rolled-over portion overlapping the eye of said main spring leaf, wherein said spring leaves are protected against expanding or fanning out in the vertical direction by limiting vertical space between said rolled-over portion and said eye and are protected against lateral shifting or splaying by a rib guide extending in the longitudinal direction of said spring assembly, lying in an end area of said main spring;
• and
• at least one intermediate spring leaf between said main spring leaf and said supporting spring leaf, wherein said main spring leaf, said intermediate spring leaf and said supporting spring leaf are held together in the vertical direction via said supporting spring leaf, and wherein said intermediate spring leaf and said supporting spring leaf are protected against splaying by said rib guide, and wherein, in the vertical direction of said rib guide, having a clearance of movement between the spring eye of said main spring leaf and said rolled-over portion of said supporting spring leaf which is less than overlap height of said rib guide, wherein the rib guide includes a guide rib in one of the intermediate spring leaf and the supporting spring leaf and a location groove in the other of the intermediate spring leaf and the supporting spring, the guide rib and location groove having mutual overlap.
