ABSTRACT:
A unit guide wear plate which aligns the movement of a brake beam end guide within the side frame of a railroad car truck so that the brake shoes can provide the maximum amount of force against the wheels when stopping the railroad car. The unit guide wear plate is comprised of a wear plate body, having a u-shaped cross section, a first side wall, having a first inner surface and a first outer surface; a second side wall, having a second inner surface and a second outer surface; a third side wall having a third inner surface and a third outer surface; wherein the first side wall is located such that it is attached to the third side wall opposite the second side wall; a first flange extension protruding from the first side wall and a second flange extension protruding from the second side wall; a pair of dimples arising out of the second outer surface for securing the unit guide wear plate within a railroad car side frame; a spring tang for providing a lateral force on a brake beam end guide as it lies within the unit guide wear plate body; and a first ramp extending outward from the first inner surface and a second ramp extending outward from the second inner surface, for aligning the brake beam end guide within the unit guide wear plate body.
