An elastomer spring, particularly for rail vehicles, comprises a core made of metal or plastic; an outer sleeve that also consists of metal or plastic; a cushion made of elastomer material, in the form of a layered spring that is arranged between the core and the outer sleeve; as well as a base chamber that is configured below a core offset. The elastomer spring is configured in multiple steps in the vertical direction X, specifically consisting of at least a first spring and a second spring, whereby a chamber is present between two springs, in each instance.

Elastomer spring especially for rail vehicles

A sleeve (), particularly a rod sleeve, at least consisting of a core comprising a core hub () that has two faces (), and comprising a core pin (), which extends in the direction of longitudinal axis Y and which projects over both faces of the core hub while forming two connecting journals (). The inventive sleeve also consists of an outer sleeve () and of an elastic layer () located between the core hub () and the outer sleeve (). The core hub () and the core pin () form a one-piece core system that is provided, however, in two parts with regard to the normal X to the longitudinal axis Y, whereby both core halves (A, A) are assembled with interference fit by means of an insertion-slot system (). The core hub () between its two faces () undergoes a tapering with an angle change&#x3b1;, whereby the respective contact surfaces () of the core hub and of the outer sleeve () extend in a manner that essentially corresponds to the elastic layer (). The outer sleeve () and the elastic layer () are provided in two parts with regard to the normal X to the longitudinal Y. Both sleeve halves (B, B) are assembled with interference fit by means of an insertion-slot system (), whereas both elastic layer halves (C, C) are placed at a distance Lfrom one another.
