A front derailleur on bicycle is designed to shift the chain to
with the desired sprocket of the chainwheel. There are many
considerations on the front derailleur because it is installed
in limited space between the seat tube and the chainwheel. It
works tight side of the chain so its shift effort is larger.
More, the of the commercial front derailleur with the different
frame is However, the local manufacturers have few design rules
on thers. The objects of this study are to develop design
rules of ther, improve the compatibility of the front
derailleur with theand This study presents a procedure of
analyses and designs for the derailleurs. The data of the
frame and the sprockets can be used displacement analysis,
static analysis, sensitivity analysis,, plate design and plate
motion range design. Further, this study design-cable joined
cam to instead the conventional cable joined joined cam makes
the better control of the alteration of themake the shift
lighter.
