Abstract

L'invention concerne un ensemble roue entièrement électrique comprenant un moyeu (1) et un pneu (2). Un espace de logement fermé est disposé dans le moyeu (1) et une roue solaire (4) est disposée dans l'espace. Des engrenages planétaires (5) entraînés en rotation par des moteurs à aimants permanents (6) sont disposés dans la direction axiale de la roue solaire (4). Le nombre Z de dents de la roue solaire (4) et le nombre N d'engrenages planétaires (5) satisfont la formule Z = KN, dans laquelle K et N sont des nombres entiers supérieurs à 2. L'ensemble roue entièrement électrique adopte de multiples rotors à aimants permanents (6) et transfère un couple et une vitesse de rotation à la roue solaire (4) en entraînant les engrenages planétaires (5) sur l'arbre de sortie des moteurs à aimants permanents (6). La roue solaire (4) entraîne finalement le moyeu (1) en rotation. Les multiples moteurs à aimants permanents (6) sont agencés sous la forme de planètes et entraînent la roue solaire (4) de façon commune. Dans l'intervalle, l'augmentation du couple et de la puissance peut être réalisée et il n'est pas nécessaire que la dimension axiale des moteurs (6) soit augmentée. L'espace du moyeu (1) est pleinement exploité et l'apparence fondamentale du moyeu (1) est conservée.
