Abstract

The present invention relates to a kind of speed-change device for bicycle, especially to a device which has a transmission gear,disposed on a rear shaft, connected with an internal hub to make the latter rotate. The internal hub accommodates an eccentrictransmission wheel connected to a rotational disk via a pair ofoblique arms. The rotational disk is connected with a triangular transmission wheel having a plurality of lugs, each lug is connected to a one-way ratchet wheel connected with the planet gear of one planetary gear set, and the sun gear of the planetary gear set is connected with an external hub, the external hub envelopes theinternal hub. When the torque transmitted from the transmission gear is increasing, the rotational disk urges the eccentric transmission wheel in eccentric state to increase the speed or torque of theplanetary gear set via the triangular transmission wheel. Finally the sun gear of the planetary gear set makes the speed or torque of the external hub increase to drive the bicycle wheel.
