(FR) CONSTRUCTION DE ROUE
Abstract
(EN)
A wheel construction (10) includes a wheel rim (12) which in use, receives a tyre (13), the rim (12) being circular and having axially inner and outer portions (19, 20) each of which provides a flange (24) which in use provides a seat for a bead (26) of the tyre (23), and the wheel construction (10) including a mid-portion (29) between the inner and outer portions (19, 20), and side parts (30), connecting the mid (29) and outer portions (19, 20), the mid-portion (29) including a circumferential well (28) where the radius of the wheel rim (12) is a minimum, at least one of the side parts (230) including a plurality of curved regions (38, 39), the plurality of curved regions (38, 39) each being immediately adjacent to each other whereby the side part (30) is continuously undulate. Each curved region (38, 39) provides at least a further two circumferential wells (40, 41). For each adjacent two curved regions, there is an effective angle between a plane normal to the axis of the wheel and a line struck tangentially at a point of inflection between the two curved regions at a tyre side of the rim, of between 25° and 45°.
(FR)
Construction de roue (10) comprenant une jante de roue (12) qui en cours d'utilisation reçoit un pneu (13), la jante (12) étant circulaire et ayant des portions intérieures et extérieures de manière axiale (19, 20), chacune constituant un flasque (24) qui en cours d'utilisation procure une portée pour un talon (26) du pneu (23), et la construction de roue (10) comprenant une portion intermédiaire (29) entre les portions intérieures et extérieures (19, 20), et des parties latérales (30), reliant la portion intermédiaire (29) et les portions extérieures (19, 20), la portion intermédiaire (29) comprenant un passage circonférentiel (28) où le rayon de la jante de roue (12) est un minimum, au moins une des parties latérales (230) comprenant une pluralité de régions courbes (38, 39), la pluralité de régions courbes (38, 39) étant chacune immédiatement adjacente l'une par rapport à l'autre, ce par quoi la partie latérale (30) est ondulée de manière continue. Chaque région courbe (38, 39) forme au moins deux passages circonférentiels supplémentaires (40, 41). Pour chaque ensemble de deux régions courbes adjacentes, il y a un angle efficace entre un plan perpendiculaire à l'axe de la roue et une ligne marquée de manière tangentielle en un point d'inflexion entre les deux régions courbes au niveau d'un côté pneu de la jante, compris entre 25° et 45°.
