Abstract
A friction wedge for a railroad car truck including a body and a wear member. The body includes a front face having a pocket adapted to removably receive the wear member. The pocket includes a bottom wall and a peripheral side wall extending outwardly from the bottom wall. The wear member includes a wear pad having a first wall and a connector member such as an adhesive layer attached to the first wall. The connector member removably attaches the first wall of the wear pad to the body. The peripheral side wall of the pocket extends around a side wall of the wear pad and prevents lateral sliding movement of the pad member with respect to the bottom wall of the pocket. The wear pad includes a second wall that is adapted to slidably engage the side frame of a railroad car truck to provide dampened movement of the bolster of the truck. The wear pad may be easily removed from the pocket when worn and replaced with a new wear pad while the body may be reused.
