BICYCLE Russian patent published in 2004 - IPC

FIELD: transport engineering; bicycles. SUBSTANCE: invention relates to bicycles with electric transmission and flywheel which can be used for stabilization of bicycle. Smaller sprocket 9 of pedal drive is connected through overrunning clutch 10 with drive wheel 11 and is installed independently on axle 13 of rear wheel 1 without coupling with rear wheel 1. drive wheel 11 is installed on axle 13 independently from rear wheel 1, and it provides stabilization of bicycle when pedals 6 are rotated. First electric generator 12 is coupled through drive wheel 11 with pedal drive and is connected with capacitive accumulator 15. Second electric is coupled with rear wheel 1 and is connected with capacitive energy accumulator 15 with possibility of operation as traction motor. Generator mode of second electric generator 12 is used for regeneration of energy at freewheeling or riding down the slope. Proposed design, owing to additional stabilization from drive wheel 11, provides possibility of charging capacitive energy accumulator at forced standstill or slow-speed riding. EFFECT: enlarged operating capabilities. 1 dwg
