ABSTRACT:
In a railroad car truck an elastomeric device is used to operatively connect each axle end of the wheelsets to a respective pedestal jaw of the side frames. The elastomeric device may comprise an elastic pad affixed between two metal plates. By choosing an elastic material having a relative high stiffness in shear, movements between the wheelsets and side frames are cushioned while at the same time the wheelsets and side frames are held in a substantially squared relationship. The squared relationship improves the dynamic stability of the truck by increasing its critical speed to allow higher speed travel.
