Abstract
An elastomeric spring assembly for a railcar apparatus is disclosed. The elastomeric spring assembly includes an elongated body of elastomeric material having a series of axially spaced members coaxially arranged and wholly embedded within the body of elastomeric material. The majority of the embedded members are configured to resist radial outward movement of said elastomeric material while causing the elastomeric material to react in an axial direction between confronting surfaces defined by the members upon axial deflection of the elastomeric spring whereby enhancing performance characteristics of the spring assembly. A method of making an elastomeric spring assembly is also disclosed.
