State of friction aperfeicoado for employment in the cavity of the rocker arm of a trick of vagao ferroviario stabilized and trick aperfeicoado of vagao ferroviario stabilized

摘要

A friction member for use in the bolster pocket of a stabilized railroad car truck has a slanted friction surface adapted to bear against the bolster within the bolster pocket and a vertical friction surface adapted to bear against the side frame. The slanted friction surface has a generally flat portion at the lower end thereof and a generally arcuate portion at the upper end thereof. The two portions of the slanted friction surface are tangent, one to another, with the point of tangency being located so as to insure full contact between the vertical friction surface and the adjacent side frame.
