Abstract:
A thrust plate is provided. The thrust plate includes a first side surface and a second side surface. The thrust plate also includes an inner surface and an outer surface extending axially between the first and second side surfaces respectively. Further, the inner and outer surfaces of the thrust plate define an inner diameter and outer diameter respectively. The thrust plate further includes a number of mounting apertures extending between the first and second side surfaces. The number of mounting apertures is defined proximate to the outer diameter of the thrust plate. A wear layer is positioned radially inward from the mounting apertures. The wear layer is integrated into a stepped portion defining a wear prone area on the first and/or second side surfaces. Further, the wear layer is made of a material different from that of a core of the thrust plate.
