ABSTRACT:
A primary suspension spring disposed between a wheel journal and a railway truck side frame includes top and bottom elastomeric members which form a ring around the journal. Both members include a relatively large cut-away portion towards their centers to provide soft vertical and longitudinal spring rates for a car body. Relatively small amounts of elastomeric material are disposed longitudinally towards the front and rear of the large cut-away portions towards the tangents of the wheel journal.
