This invention discloses a bicycle ratchet bushing, comprising a bushing for
coupling to a connecting axle rod to drive the bicycle wheel to rotate, a pawl
ring disposed on the inner side of the bushing, a plurality of pawls interdentally
dispersed around the outer periphery of the ratchet ring, a resilient ring surrounding
each pawl, such that the inner end of the pawl is a pivotal circular turning end,
and the outer end is a moving end capable of opening outwards and retracting, and
a pawl ring being sheathed outside the ratchet wheel, such that a buffer space
is designed at the internal diameter of the pawl ring to prevent noise production
from friction between the resilient ring and the pawl ring of the bushing.
