<p>The invention relates to a mechanism that transmits torque and speed of rotation from an input axle to an output axle in a continuously variable way, characterized by the fact that it comprises two planetary gear sets arranged along parallel axes, said planetary gears having teeth on the external perimeters of their ring gears (4, 13) that mesh one with another on their external perimeters, in such a way that if one of said ring gears rotates in one sense, the other of said ring gears rotates in the opposite sense, affecting the rotations of the other pieces that make up each planetary gear set, said pieces including for each planetary gear set a solar gear (2, 11), planetary gears (3, 12) and a planetary carrier (5, 14), making, in this way, a continuous variation of the transmission ratio existing between two central axles of the above mentioned planetary gear sets.</p> |
