Abstract
A new improved mechanism is described for dampening forces between the sideframes and bolster of a railroad car truck or bogie. The mechanism comprises a pair of triangularly shaped wedges which are positioned between a pair of wear plates carried by each of the sideframes and an adjacent pair of inclined wear plates which are disposed in a pair of wedge pockets which are formed adjacent each of the opposing ends of the bolster. The inclined wear plates of the bolster are bolted, in place, rather than being conventionally welded. Space is provided for the nuts and bolts by removing and redirecting the top side of the bolster, adjacent the inclined wear plates, to intersect the inclined wear plate in the area of line contact between the inclined wear plate and adjacent curved surface of the wedge to buttress or reinforce the slotted bolster in this area.
