<p>1344699 Brake discs GOODYEAR TIRE & RUBBER CO 18 May 1971 [24 June 1970] 15502/71 Heading F2E A wheel brake disc assembly comprises a plurality of beryllium segments forming an annular core between steel annuli, each segment having at least one edge surface extending at an angle to a radial line, a plurality of metallic inserts received between the steel annuli, each insert being positioned between adjacent segments and having surfaces complementary to the edge surfaces of the adjacent segments for torque transfer, first fasteners securing the steel annuli to the segments, and second fasteners securing the inserts to the annuli. The steel annuli either comprise single plates 10, 12 or sets of 120 degree segments, the beryllium segments 18 overlapping the joints. The beryllium segments 18 extend 60 degrees and at each segment joint there is a steel insert 40, rivetted to the steel annuli, in a V-groove between angled faces of the beryllium segments 18. Axial grooves 20 through the inserts 40 and annuli, centrally situated over the beryllium segment joints, accept wheel splines or keys. Rivets 24 fixing the beryllium segments 18 to the steel annuli, are contained in cambered steel bushings 26, the lips 30, 32 of the annuli being bent inwardly to aid fastening.</p> |
