ABSTRACT:
In order to attain a cost-effective manufacturing, suitable for large-scale production, in the case of a rail wheel, and, at the same time, a high degree of structural strength, whereby the wheel disk, which rigidly joins the wheel hub (4) with the wheel tire in a fibrous composite type of construction, is made of two external fibrous composite surface layers and a characteristically light inner core, which transmits shearing force, arranged between them, the inner core is composed, according to the invention, of ring segment-shaped, foam plastic-filled fibrous composite hollow cases (22), each consisting of web portions (28), running radially between the wheel hub and the wheel tire, arranged perpendicularly to the surface layers, with an intersecting fibrous orientation, slanted at an angle to the longitudinal direction of the sections, as well as profile side walls (30), formed in one piece, on the longitudinal edges of the web portions, with a continuous fibrous structure, each evenly bonded with the inner surface of the surface layers, and of segment extensions (32, 34), lying contiguously, in one piece, on the web portion ends, forming the outer and inner surrounding edges of the hollow cases.
