Abstract

L'invention concerne un dispositif d'entraînement de moteur intégré à la roue (21) qui entraîne en rotation un arbre d'entrée de décélérateur (25) possédant des sections excentriques (25a, 25b), en utilisant une unité de moteur (A), décélère la rotation de l'arbre d'entrée de décélérateur (25), en utilisant une unité de décélération (B), et transmet celle-ci à un arbre de sortie de décélérateur (28). L'unité de décélération (B) comprend : l'arbre d'entrée de décélérateur (25) ; des plaques courbées (26a, 26b) qui tournent autour du centre de l'arbre de rotation conjointement avec la rotation de l'arbre d'entrée de décélérateur (25) ; une goupille externe (27) qui provoque un mouvement d'autorotation des plaques courbées (26a, 26b) ; et un mécanisme de conversion de mouvement qui convertit le mouvement d'autorotation des plaques courbées (26a, 26b) en mouvement de rotation autour du centre de l'arbre de rotation de l'arbre d'entrée de décélérateur (25) et transmet ledit mouvement à l'arbre de sortie de décélérateur (28), par insertion d'une goupille intérieure (31) maintenue par l'arbre de sortie de décélérateur (28) dans un orifice passant (30a) dans les plaques courbées (26a, 26b) et en faisant en sorte que celle-ci se joigne aux plaques courbées (26a, 26b) par l'intermédiaire d'un roulement à rouleaux en forme de goupille (31a). L'écartement interne radial initial dans le roulement à rouleaux en forme de goupille (31a) va de 5 à 30 µm.
