HIGH EFFICIENCY PEDALING MECHANISM OF BICYCLE

摘要

PROBLEM TO BE SOLVED: To provide a high efficiency pedaling mechanism that realizes a noncircular pedaling path by a link mechanism. SOLUTION: The highly efficient noncircular path having large generating power is approximately realized by using a coupling path of a four-node link mechanism. The noncircular pedaling path is not required to be limited to one kind. An appropriate path can be selected according to the usage of, for example, a racing bicycle with which backward pedaling can be used and a general bicycle only for forward pedaling.
