ABSTRACT:
A disk wheel, especially a railroad wheel, has a composite construction of a single piece metal hub and a single piece metal rim connected to each other by a wheel disk of fiber reinforced composite material providing exclusively adhesive bonds. The wheel disk transmits shearing stress between hub and rim. The rim is provided with two radially inwardly extending rim flanges. The hub has two radially outwardly extending hub flanges. The shearing stress transmitting wheel disk (12) has a radially outer rim contacting surface (9) adhesively bonded to the rim (3) and rim flanges (7), and a radially inner hub contacting surface (8) adhesively bonded to the hub (2) and hub flanges (6). The wheel disk (12) is inserted into the space between the concentrically arranged hub and rim as long as the composite material is not yet cured and hence sufficiently deformable. The wheel disk is exposed to compression during curing. After the curing a cover disk is adhesively bonded to the rim, hub, and wheel disk on both sides of the wheel. Preferably, the wheel disk is made of a plurality of box type or shell type truncated sectors.
