The invention concerns a toric reinforced rubber membrane (M), used for supporting a tubeless tyre (P) tread and constituting with said tyre and its mounting rim (J) a wheel assembly (E), characterised in that when it is inflated at a pressure (p0) higher than pressure (p1) of the tyre (P) cavity, it has, in inflated state, a top radius (RM) less than the crushed radius (RE) of the tyre used at its recommended pressure, said membrane (M) being at its top (1) reinforced by a breaker ply (12) and a binding reinforcement (13), consisting of tyre yarns or cords oriented circumferentially, and in its sidewalls (11) by at least one reinforcement ply (120), wound around a ring-shaped reinforcing element (2) with breaking force slightly greater than that of the binding reinforcement.
Membrane torique (M) en caoutchouc renforcé, utilisée comme moyen de support de la bande de roulement d'un pneumatique (P) sans chambre à air et constituant avec ledit pneumatique (P) et sa jante de montage (J) un ensemble roulant (E), caractérisée en ce que, gonflée à une pression (p0) supérieure à la pression (p1) de la cavité du pneumatique (P), elle a, à l'état gonflé, un rayon de sommet (R M) inférieur au rayon écrasé (R E) du pneumatique utilisé à sa pression recommandée, ladite membrane (M) étant en son sommet (1) renforcée par une armature de sommet (12) et une armature de frettage (13), composée de fils ou câbles orientés circonférentiellement, et dans ses flancs (11) par au moins une nappe de renforcement (120), enroulée autour d'un élément annulaire de renforcement (2) présentant une force de rupture légèrement supérieure à celle de l'armature de frettage.
