RBS Regenerative Braking System (for Bicycles) ME 599-2003-02 by: Michael Resciniti Adi Peshkess Peter Leonard Date: 12/15/2003 Abstract When sit a cps, a great amount of kinetic readiness is lost when braking, making start up fairly strenuous. The remnant of our project was to develop a harvest-feast that stores the energy which is ordinarily lost during braking, and reuses it to help propel the rider when starting. This was accomplished with a spring and chamfer shape system whose parameters were optimized based on engineering, consumer preference, and manufacturing models. The resulting harvest-tide is one which is practical and potentially very profitable in the market place. A spring (of tension 22,100 N/m) is stretched (at just about 37cm) by a wire which wraps around a cone (of 15 cm large diameter and 2 cm small diameter), while braking. A clutch is then released and the cone drives the bikes lurchs to assist the rider while starting. The product weighs 14 lbs, will cost $87, and will return 85% of the riders stopping energy when starting up again.
