La roue (10) de l'invention comporte un corps de roue (12) dont la jante est interrompue pour constituer une pluralité de segments de jante (20) en forme d'arc de cercle, mutuellement espacés et délimitant des portions de gorge respectives, ainsi qu'un pneumatique (14) comportant un talon (44) propre à être reçu dans les portions de gorge des segments de jante et incorporant au moins un renfort annulaire agencé pour contraindre le talon (44) dans les portions de gorge, ce qui permet de réaliser une roue de structure allégée. Application notamment aux machines agricoles.
摘要:
A tire rim structure including an annular inner ring (2) provided on the inner ring of a tire body (1) and a circular outer ring (3) provided on the outside of the tire body (1), fixedly connected to the annular inner ring (2), and formed by stamping. The annular inner ring (2) includes an annular inner ring body (21) formed by extrusion, an annular left ring (22) provided at one side of the annular inner ring body (21) and formed by extrusion, and an annular right ring (23) provided at the other side of the annular inner ring body (21), connected to the circular outer ring (3), and formed by extrusion. A shaft hole (31) is provided at the middle part of the circular outer ring (3). By breaking down a tire rim into the annular inner ring body (21), the left ring (22), the right ring (23), and the outer ring (3) connected to the right ring, each of the components composing the tire rim can be processed and formed via extrusion or stamping processes, this provides increased consistency compared with an existing tire rim that is integrally processed and formed via a casting process, thus allowing for increased structural strength and simplified manufacturing process.
摘要:
This invention provides a light-alloy vehicular wheel. In this light-alloy vehicular wheel, a forged material or a cast and forged material is used for at least a disc (1, 6, 13) and a rim (5, 7, 8) or an inner rim member (3), which is produced separately from the disc, is jointed with the disc (1, 6, 13) by a friction grip jointing method. It is possible to joint a unitary molded product consisting of an outer rim member (2, 12) and disc (1, 13) and composed of forged light alloy or cast and forged light alloy with the inner rim member (3) of cast light alloy by a friction welding method, and joint a unitary molded product consisting of outer and inner rim members and constituting a rim (5) of a cast light alloy with a disc (6) of a forged light alloy by a friction welding method. A primary body (8) of the inner rim member can also be spin molded by molding outer and inner rim members unitarily by a casting method.
