Abstract

L'invention fournit une roue en deux pièces pour véhicule dans laquelle des orifices d'insertion de valve à air destinés à insérer une valve à air ne communiquent pas avec une partie creuse, empêchant ainsi les infiltrations dans la partie creuse d'eau, de salissures, ou similaire. Un élément disque (10) de forme sensiblement circulaire et possédant d'un bloc un disque (11) et une partie extrémité côté externe (12) de jante, et un élément jante (20) de forme tubulaire sont liés. L'élément disque possède une partie en retrait (12d) de forme annulaire, et possède également une paire de premières faces de liaison (12bj, 12cj) de forme annulaire et positionnées côté externe et interne dans la direction radiale de la partie en retrait de forme annulaire. L'élément jante possède une paire de secondes faces de liaison (20bj, 20cj) de forme annulaire qui sont individuellement liées à la paire de premières faces de liaison, qui ferment la partie en retrait, et qui forment la partie en retrait (12d). Les orifices d'insertion de valve à air (40, 41) qui traversent individuellement l'élément disque et l'élément jante, et dans lesquels est insérée la valve à air (30), sont également agencés dans la roue en deux pièces pour véhicule (100). Ainsi, la valve à air est fixée dans l'élément disque, et les orifices d'insertion de valve à air côté élément disque sont scellés par la seule valve à air.
