<p>A disc brake assembly for a railway truck is provided. The truck (10, 11) includes at least two wheel axle sets (22, 23) and brake discs (12, 13) mounted to the wheel axle sets (22, 23). Extending between the wheel axle sets (22, 23) is a longitudinally extending truck frame (20, 21). Also extending between the wheel axle sets (22, 23) and supporting the truck frame (20, 21) via primary springs (65) are equalizer beams (64) that further extend beyond the wheel sets (22, 23) and through an opening (70) in the truck frame (20, 21). Disc brake calipers (62) are mounted to the equalizer beams (64) with the caliper (62) engaging the brake discs (12, 13) of the wheel sets (22, 23). The assembly results in the brake discs (12, 13) and calipers (62) being unsprung. In other words, the brake discs (12, 13) and calipers (62) do not move relative to each other.</p> |
