CA 2069745

A single-piece wheel rim (J') having tapered seats (2') inclined at 15° U 1° with greatly reduced axial widths (P') relative to the axial widths (P) of known tapered seats (2), and having a reduced height (H') mounting well (3') leaving more room for the brake elements. A wheel rim (J') of this kind can be combined with a tyre (T) having beads with truncated toes to provide beads with greater fatigue strength while allowing easy mounting. The invention relates to tyres and wheel rims for heavy vehicles.

L'invention concerne une jante monobloc (J') ayant des sièges tronconiques (2') inclinés à 15° ~ 1°, dont les largeurs axiales (P') sont fortement diminuées par rapport aux largeurs axiales (P) des sièges tronconiques (2) connus, et à gorge de montage (3') de hauteur (H') amoindrie de manière à permettre l'augmentation de l'espace disponible pour les moyens de freinage. L'ensemble d'une jante (,7') telle que décrite ci-dessus et d'un pneumatique (T) ayant des bourrelets dont la pointe a été tronquée permet une meilleure résistance desdits bourrelets à la fatigue tout en permettant n montage facile. Application de l'invention est faite aux pneumatiques et jantes destinés aux véhicules lourds.
