TRANSMISSION MECHANISM FOR BICYCLES BY MEANS OF A LEVER AND A ROTATING PLATE, ADAPTABLE TO OTHER TYPES OF VEHICLES

摘要

The invention relates to a lever comprised of a displaceable bar which is adapted and modifies the drive propulsion system known as crankshaft. The maximum mechanical advantage that is obtained in the torque within one revolution results from increasing the length of the lever or bar during its displacement between the force application point and the fulcrum (see figure 5A), said lever or displaceable bar remaining synchronized by a shaft to a number "X" of displaceable bars according to the specific requirements of the torque to be obtained.
