ABSTRACT:
In accordance with the present invention a diagonal strut for a railway trailer hitch is provided including a rubber-in-shear cushioning assembly including a center member and spaced outer members. Elastomeric material is bonded to the center member and spaced outer members. A fixed portion of the diagonal strut is attached to the car deck or to a plate adapted to be attached to the car deck. A movable portion of the strut is attached to the head of the hitch. In one embodiment the center member is movable relative to the spaced side members under buff loads to put the resilient material in shear, and under draft loads the spaced side members are movable relative to the center member to put the resilient material in shear. In another embodiment the center member is movable relative to the spaced side members under draft loads to put the resilient material in shear, and under buff loads the spaced side members move relative to the center member to place the elastomeric material in shear.
