Abstract

A disc wheel, particularly for rail vehicles, with a composite metal/plastic structure. In order to make possible simple manufacture with at the same time adequate force transmission, a structure between the hub and the tread comprises a plastic structure comprising two half shells of the same design which are subdivided in sector fashion by spoke-like reinforcement ribs. The reinforcement ribs each have a longitudinal slot into which rib plates are inserted which connect the two half shells to each other. Advantageously, plastic foam is inserted into the cavities of the half shells. All joints between the plastic structure and the hub or the tread are cemented joints.
