Structural Analysis of Existing Multi-Speed Transmission Hubs of Bicycles

  • Yi-Chang Wu

Abstract

This paper presents the analysis of topological structure of multi-speed transmission hubs for bicycles. Three existing transmission hubs with 8-speed, 11-speed and 12-speed are introduced. The topological structure of each gear mechanism, which is the main body of a transmission hub, is analyzed. The degrees-of-freedom (DOF) of the transmission hub is calculated by the Kutzbach’s equation. The related clutching sequence table for each transmission hub is also listed.
