Elastomeric pad for a compressible elastomeric spring.

Se describe una almohadilla elastomérica elástica comprimible que incluye un cuerpo que define un eje central, el cuerpo se forma a partir de un material predeterminado y tiene cada una de una superficie lateral periférica, un primer extremo axial y un segundo extremo axial, cada uno del primero y segundo extremos axiales tiene una superficie sustancialmente plana del mismo dispuesta normal al eje central. Una primera proyección elevada se forma centralmente sobre la superficie plana del primer extremo axial, y una segunda proyección elevada se forma centralmente sobre la superficie plana del segundo extremo axial. Una primera ranura se forma en la superficie plana del primer extremo axial en relación de empalme con una superficie lateral periférica de la primera proyección, y una segunda ranura se forma en la superficie plana del segundo extremo axial en relación de empalme con una superficie lateral periférica de la segunda proyección.

Combination of a yoke and an elastomeric draft gear

A draft gear assembly (10) which is mountable within a yoke (20) of the railway vehicle for cushioning buff and draft dynamic impact forces encountered during make-up and operation of a railway vehicle includes a compressible spring (102) positioned intermediate the front coupler follower (60) and the rear follower (50) in alignment with the longitudinal axis of the yoke. A pair of axially aligned compressible springs (102a, 102b) may be also provided being either separated by a center plate (200) or by a wall (212) of the yoke.
