Abstract
A laminated mount for a railway vehicle suspension system is provided in which a body of elastomer is disposed between a top and bottom plate, and is divided into a plurality of individual layers by shims embedded at spaced intervals therewithin. Pins extend between the undercarriage of the vehicle and a bearing plate which is embedded between two layers of elastomer such that at least one layer of elastomer is disposed between the bearing plate and the bottom plate. The pins extend through selected layers of elastomer and effectively prevent them from deflecting in shear in response to lateral and/or longitudinal movements of the vehicle. This enables the mount herein to be designed with the combination of a relatively stiff shear spring rate to provide stability of the vehicle, and a soft compression spring rate to provide flexibility in response to vertical movements of the vehicle for wheel load equalization.
