ABSTRACT:
In an elastomer-in-shear cushioning assembly is provided within the diagonal strut of a railway car trailer hitch. Elastomeric material is bonded to a fixed portion of the strut and to a portion of the strut which is movable relative to the fixed portion. Elastomer-in-shear cushioning is less expensive and has lower maintenance costs than hydraulic units. Elastomer-in-shear units absorb considerably more energy per unit volume than rubber-in-compression units. The elastomeric material may be placed under lateral compression to increase the fatigue life of the elastomeric material. Cover plates may be attached to the cushioning assembly to maximize the amount of energy absorbed per unit length of displacement.
