- 16 - ROGERS, BERESKIN & PARR TITLE: BRAKE DISC DESIGN FOR WHEEL MOUNTED DISCS ABSTRACT OF THE DISCLOSURE A brake disc for mounting to a railroad wheel or the like comprises a plurality of segments. Each segment is of part annular configuration and has two mounting tangs at a radially inner edge. Bolts pass through the mounting tangs to affix the segment to the wheel. The wheel is provided with an inwardly directed flange at its rim in order that retention tangs at the radially outer edge of the segment are captured between the flange and the web of the wheel. Under heat gener- ated during braking the segment can expand radially out- wardly. The segment is prevented from curling or warp- ing in the axial direction by the flange of the wheel and the retention tangs. Preferably the mounting tangs have a part curved configuration so as to accommodate expansion of the segment by bending of the mounting tangs. The mounting tangs can be fitted with an axially extending lip so as to locate the segments and resist centrifugal forces during rotation.
