  • Patent number: 6468178
    Abstract: A rear wheel hub and chainless drive train gear assembly for use on a bicycle having an axle bracket fixed to the frame of the bicycle, a spindle extending axially through the axle bracket and left and right pedal crank arms for rotating the spindle upon application of a pedaling force. A primary drive gear fitted to the spindle drivingly engages carrier gears which operate a planet gear cage housing and a multiple planetary gear and sun gear arrangement according to various gear ratios determined by selective operation of a clutch assembly. Planetary gear groups each include an integral set of planetary gears of varying size which mesh with corresponding sun gear rings. Operation of the clutch assembly serves to selectively engage pawl stops with a corresponding sun gear ring, thereby engaging the corresponding sun gear ring with one of the planetary gears of the planetary gear groups according to a selected gear ratio.
