Design of 3-Speed Bicycle Transmission Hubs

Abstract:

This paper presents the embodiment designs of 3-speed transmission hubs which consist of basic planetary gear mechanisms and gear-shifting control mechanisms. Two feasible clutching sequence tables are synthesized by analyzing the kinematic structure of the gear mechanism. A mechanical control mechanism is used to control the engagement or disengagement of each clutch to guide the power flow from the rear sprocket via the gear mechanism to the hub shell. The power transmission path at each gear stage is further checked to verify the validity of the transmission hub. The embodiment designs of two 3-speed transmission hubs are presented.
