Prongs may have trapezoidal shape. An axial aperture may be also provided with the prongs located on or in close proximity to a peripheral edge of the apertures. Prongs may be also provided on the opposed surface of the plate for mechanically interlocking the plate with an axial end of another abutting elastomeric pad. Annular ring-like projections are also provided for mechanically interlocking the plate to at least one elastomeric pad.
