Abstract:
1. A planetary transmission for a bicycle, comprising: a first rotatable element, which is an unbalanced element, as a receiver of power from a foot's muscular energy and gravitational energy, converting both of them into mechanical energy for transmitting the driving power via a one-way directional second rotatable element, and a third opposing rotatable element to a driving sprocket of a bicycle, which is attached to the third element and freely rotates with this third element on a crank axle for transmitting of the driving power via a chain to a free wheel and then to a drive wheel of a bicycle, where the bicycle is in a course of forward motion from the pedals, and the first rotatable element, being connected to the crank by means of a leading axle, rotates clockwise together with the crank axle into positive zone of rotation, and in the negative zone of rotation, where the inertial energy is appearing, due to the increased speed of rotation in the positive (active) zone of rotation, and at the same time the first element rotates counter-clockwise around its own axis of rotation together with the leading axle, while the second rotatable element being connected to the first rotatable element by means of the overrunning clutch, and also connected to the third element by means of toothing, rotates clockwise around the third element and around the crank's axes of rotation, and powered the same way as the first element on its clockwise rotation, and at the same time the second element rotates counter-clockwise around its own axle of rotation, powered the same way as the first element on its counter-clockwise rotation, and consequently, makes the third element with the driving sprocket on it, rotate faster than without the transmission using the same muscular energy.
