Definitions

  • the embodiments herein relate generally to an improvement over existing bicycle constructions by increasing torque input to a bicycle with a linear to rotary drive system, rather than a rotary to rotary drive system.
  • the bicycle constructions are based on a rotary crank pedal drive system that uses the rotary to rotary drive system and are not efficient in using the torque.
  • the rotary drive system uses only 50 % of the torque when pedal is substantially perpendicular to a derailleur system connected to pedal, thus the bicycles produced a large pedal offset. Embodiments of the disclosed invention solve this problem.
  • a bicycle pedal system is modified to increase torque input and to efficiently power a bicycle by using a pedal system in a linear to rotary drive system, rather than a rotary to rotary drive system.
  • the pedal system for a road bicycle on both first and second sides, includes a pedal arm connected to a pedal on one end and a power connector on other end. Further, the power connector is connected to a sprocket via a ratcheting arm and the sprocket is further connected to a chain and derailleur system via a drive chain.

Abstract

La présente invention concerne la fabrication de bicyclettes. Précédemment, des systèmes de pédales à pédalier rotatif étaient inefficaces pour créer un couple. A cet effet, des modes de réalisation de la présente invention utilisent un point de pivot (32) sur une roue arrière fixée à un premier ressort de rappel (16) et à un second ressort de rappel (26). Un premier bras de pédale (12) est relié à une première pédale (14) et au premier ressort de rappel tout en étant relié à un premier raccord de puissance (20) sur le premier bras de pédale. Un second bras de pédale (22) est relié à une seconde pédale (24) et au second ressort de rappel tout en étant relié à un second raccord de puissance (30) sur le second bras de pédale. Un pignon (34) s'engrène avec une chaîne d'entraînement (36) qui est reliée de façon coaxiale au premier raccord de puissance et au second raccord de puissance par l'intermédiaire d'un arbre d'entraînement relié de façon coaxiale (38). Appuyer sur les pédales crée un couple sur l'arbre d'entraînement.
