Abstract

L'invention concerne une roue de véhicule à moteur comprenant un corps de roue (10) qui comporte un zone de moyeu central (16), une bande de fond de jante (14) qui s'étend sur la circonférence de la roue et forme une embase de jante radialement extérieure, ainsi qu'une zone intermédiaire (18) située entre la zone de moyeu (16) et la bande de fond de jante (14). Un enjoliveur (82) est fixé à la face avant du corps de roue. Le corps de roue (10) est réalisé essentiellement sous la forme d'une pièce d'un seul tenant en matière plastique renforcée de fibres et la zone intermédiaire comporte sur la face avant du corps de roue une pluralité de creux (49) qui s'étendent à l'intérieur de la zone intermédiaire, qui sont ouverts à leur première extrémité tournée vers le face avant du corps de roue et fermés à leur deuxième extrémité tournée vers la face arrière du corps de roue et qui sont recouverts par l'enjoliveur (82). Pour empêcher l'eau et les autres salissures de s'accumuler dans ces creux (49), l'enjoliveur (82) est relié par liaison de matière à la face avant du corps de roue le long d'au moins une bande de jonction (46) continue et étanche aux liquides de telle façon que, lorsqu'on regarde en direction de l'axe de la roue, la ou les bandes de jonction (46) délimitent au moins une première zone de la face avant du corps de roue à l'intérieur de laquelle toutes les premières extrémités ouvertes des creux (49) sont disposées de façon que l'enjoliveur (82) obture toutes les premières extrémités ouvertes des creux (49) de manière étanche aux liquides.
