Disk wheel, especially railroad wheel

A disk wheel having a rotational central axis, especially a railroad wheel, comprising a hub, a rim, and a shear transmitting wheel disk made of fiber composite material connecting said hub to said rim, a cover disk adhesively bonded to said rim, hub, and wheel disk on each side of the wheel, two rim flanges extending substantially radially inwardly and forming an inner rim groove, two hub flanges extending substantially radially outwardly and forming an outer hub groove facing said rim groove, said shear transmitting wheel disk comprising a shear body having a meandering cross-sectional configuration in a cylindrical plane extending coaxially with said central axis, said shear body having a radially outer first wall (9) adhesively bonded to said rim and rim flanges in said rim groove (7'), said shear body having a radially inner hub contacting second wall (8) adhesively bonded to said hub and hub flanges in said hub groove (6'), said meandering shear body further having portions adhesively bonded to said cover disks which in turn are adhesively bonded to axially outwardly facing surfaces of said rim flanges and of said hub flanges, said shear body of said wheel disk comprising a plurality of box type shells each having a truncated sector configuration including a bottom wall, two radially extending side walls, said radially outer first wall (9) and said radially inner second wall (8) also forming part of each of said box type shells, each shell further having an open side opposite said bottom wall, said box type shells being adhesively bonded to each other along said side walls so that said open sides alternately face in opposite directions, whereby said bottom walls also face alternately in opposite directions to form said meandering cross-sectional configuration.
