Disclosed is a one way transmission for a motor, which has a structure for changing speed in the same direction as a motor normally rotate even when the motor rotates reversely. A one way transmission for a motor according to the present invention comprises a hub shell rotatably coupled to fixing shafts extending from both sides thereof; a built-in motor arranged in the hub shell and provided with a driving shaft; and a changing speed means mounted between the driving shaft and the hub shell to output driving rotation of the built-in motor to the hub shell in a one way with speed changed. The changing speed means comprises first and second sun gears coupled to an outer peripheral surface of the driving shaft to be spaced apart from each other, the first and second sun gears being constrained by one way clutches to have opposite directions, respectively, a first planetary gear engaged with the first sun gear, and a second planetary gear engaged with the second sun gear, the first planetary gear and the hub shell.

Transmission unilatérale pour moteur, à structure capable de changer une vitesse tout en fournissant une sortie dans la même direction que celle de la rotation avant lorsque le moteur tourne dans une direction inverse. La transmission selon l'invention comprend une coque de type moyeu qui se fixe sur un arbre fixe étendu dans les deux directions de sorte que ce moyeu puisse entrer en rotation; un moteur intégré à arbre d'entraînement placé dans le moyeu; et une unité de transmission entre l'arbre d'entraînement et le moyeu pour fournir en sortie, avec changement de vitesse, la force d'entraînement du moteur intégré au moyeu dans une direction. Ladite unité comprend un premier planétaire et un second planétaire couplés mutuellement, avec un intervalle sur une circonférence externe de l'arbre d'entraînement, et limités par un embrayage unilatéral de sorte que les deux planétaires aient des directionnalités opposées, un premier train planétaire s'engrenant avec le premier planétaire, et un second train planétaire s'engrenant avec le second planétaire et avec le premier train planétaire et le moyeu.
