Definitions

  • the invention relates to a power transmission mechanism for a bicycle, in particular a geared bicycle.
  • the bicycle of the prior art is a chain drive, which is a transmission mechanism composed of a large sprocket wheel, a chain and a chain flywheel, and has many disadvantages:
  • the uranium of the hinge pin and the sleeve are subjected to a large specific pressure, which causes relative movement with each other, resulting in wear of the hinge, which makes the actual pitch become longer and the sag increases; thus, poor meshing and chain vibration occur, resulting in greater friction. Force and component.
  • the present invention provides a transmission system bicycle composed of a gear and a tooth flywheel, that is, a tooth flywheel transmission bicycle.
  • the force resistance is increasing. Assume that the rear wheel diameter of the chain drive is D", and the rear wheel diameter of the tooth flywheel drive is D'. Then, the pedals of the bicycle travel in the same situation when stepping on one turn. Yes: The tooth flywheel drive is stepped at 3.14D'i', and the chain drive is stepped from "3.14D"i". From the analysis, it can be seen that the total gear ratio of the toothed flywheel transmission is i(i'). The transmission ratio i" of the chain drive is greatly limited.
  • the utility model has the beneficial effects that: in the actual environment of the bicycle field, since the tooth flywheel speed control function is strong, the rear wheel diameter of the tooth flywheel bicycle is smaller than the rear wheel diameter of the chain drive, so the frame is correspondingly small, the bicycle Of course, it is also miniaturized. It helps to save tire rubber and steel resources, reduce road congestion and is easy to carry and store.
  • the gear diameter of the toothed flywheel bicycle is much smaller than the diameter of the large crankset of the chain drive bicycle.
  • the size and weight of the structure are small, so the height (width) of the toothed flywheel box is smaller, flatter and more symmetrical than the full chain cover of the chain drive; the meshing force points of the tooth flywheel drive are parallel to the direction of rotation of the shaft. No component, high transmission efficiency, good lubrication.

Abstract

L'invention concerne une bicyclette entraînée par une roue à inertie dentée qui comporte un carénage de roue à inertie dentée et un élément oscillant (103) gauche prévu entre un axe central (1) et un axe arrière (5). Le carénage de roue à inertie dentée est parallèle à l'élément oscillant (103) gauche. L'axe central (1) et l'axe arrière (5) parallèle à l'axe central (1) sont placés dans le carénage de roue à inertie dentée, un engrenage menant (301) est prévu sur l'axe central (1), et une roue à inertie pourvue d'un engrenage droit est prévue sur l'axe arrière (5). n (n≥1) axes (2, 3, 4) sont prévus entre l'axe central (1) et l'axe arrière (5), les lignes axiales de ceux-ci étant parallèles à celles de l'axe central (1) et de l'axe arrière (5). Ces axes (2, 3, 4) sont reliés entre eux par des paires d'engrenages, et sont reliés à l'axe central (1) et à l'axe arrière (5) par des paires d'engrenages de manière à former un dispositif entraîné par une roue à inertie dentée.
