Torque multiplier for bicycle - has increased pedal starting force using small orbital chain drive gearwheel

摘要

The starting force exerted on the pedals (N) and cranks (J) in the first stage with a double-cogged chain drive pinion (1) of the central axis (Z) with nineteen teeth per 8mm to produce and transfer the attraction force is guided by an endless double chain (7).This has 8mm divisions over a double cogged chain gearwheel (2) with 8mm division per 18 teeth of the planetary gear wheel (3) over the double chain guide wheel (4) = 16 teeth 8mm division back to the starting point (a). The planetary gearwheel (3) is controlled with force locking engagement round the sun wheel gear (6) fixed on the gearbox cover (14). ADVANTAGE - For each pedal revolution the support disc (A) only turns half a revolution.
