WHEEL FOR INDUSTRIAL AND COMMERCIAL VEHICLES

The wheel (1) comprises a rim (2), made of a metal material, intended to carry a tyre, and an annular disc (3), also made of a metal material, fixed coaxially in the rim (2). The disc (3) comprises a radially outer annular part (4), connected to the inner surface of the rim (2), as well as a radially inner annular part (5) provided with a plurality of openings (7) for the passage of means for the fastening thereof to a hub of an axle. The radially inner part (5) of the disc (3) includes an annular wall (9) having a radially outer peripheral portion (9a) bent towards the outside, a radially intermediate portion (9x) including at least a plurality of circumferentially successive wall portions (9g) converging to the outside of the wheel (1) towards the axis (A-A) of the latter, and a radially inner peripheral portion (9b), which, at least at said wall portions (9g), is bent with respect to the latter towards the inside of the wheel (1). The radially outer and inner peripheral portions (9a, 9b) define corresponding contact areas (9c, 9d), radially outer and inner, respectively, facing towards the inside of the wheel (1) and intended to be clamped against the hub. The annular wall (9) has a plurality of reliefs (10) which protrude in a direction which is at least approximately parallel to the axis (A-A) of the wheel (1), in each of them there being provided one of the openings (7). The peripheral portions (9a, 9b) of the annular wall (9) define further outer contact areas (9e, 9f), facing towards the outside of the wheel (1) and intended to be clamped against the corresponding outer contact areas of an identical wheel assembled in a twinned configuration. La roue (1) comprend une jante (2), constituée d'un matériau métallique, destinée à porter un pneu, et un disque annulaire (3), également réalisé en un matériau métallique, fixé coaxialement dans la jante (2). Le disque (3) comprend une partie annulaire radialement externe (4), reliée à la surface intérieure de la jante (2), ainsi qu'une partie annulaire radialement interne (5) pourvue d'une pluralité d'ouvertures (7) pour le passage de moyens pour la fixation de celui-ci à un moyeu d'un essieu. La partie radialement interne (5) du disque (3) comprend une paroi annulaire (9) comprenant une partie périphérique radialement externe (9a) incurvée vers l'extérieur, une partie radialement intermédiaire (9x) comprenant au moins une pluralité de parties de paroi successives circonférentiellement (9g) convergeant à l'e
