Abstract

PROBLEM TO BE SOLVED: To provide a transmission device for a bicycle that employs no chains and is applicable to a general chain-transmission bicycle. SOLUTION: A front bevel gear pair 2 has a large bevel gear 21 incorporated with a pedal shaft of a bicycle and a small bevel gear 22 rotatively meshed with the large bevel gear 21, and a rear bevel gear pair 4 has a large driven bevel gear 41 incorporated with a rear wheel shaft and a small transmission bevel gear 42 rotatively meshed with the large driven bevel gear 41. An inflective element 5 is connected to the output end of the small bevel gear 22 so as to be rotated along therewith. The front end of a rigid element 6 connected to the input end of the small transmission bevel gear 42 and the rear end of the inflective element 5 connected to the front bevel gear pair are connected so as to be rotated together. A rotation by pedaling provides mutual rotations between the front bevel gear pair 2, the rear bevel gear pair 4, and the inflective and rigid elements 5 and 6 connected between them to thus rotate the rear wheel and then drive the bicycle forward.

However, the creative techniques disclosed in the above-mentioned U.S. patents or designs have no commonality, cannot be applied to the conventional chain-driven bicycle body, and have their own unique bodies. Without it, the chainless transmission cannot be installed. Therefore, a bicycle having a conventional chain transmission cannot be easily converted to a bicycle having a chainless transmission. The main obstacle of the technology is that the axes of the front and rear bite gears are located on the same horizontal plane, so the body structure of the bicycle must be changed. Therefore, the installation of a chainless transmission requires the design of its own body. For this reason, a conventional chain-driven bicycle cannot be directly changed to a chain-less driven bicycle.
