ABSTRACT
At the beginning of the preliminary step of the project, we came to know about the important application of the
flywheel and dynamo. In actual bicycle the kinetic energy obtained from the pedaling power is utilized and is not
recovered. By designing and fabricating the flywheel bicycle with mobile charger fetches you the recovery of the kinetic energy produced from
the pedaling power and also with addition of mobile charger by the use of the headlight generator (dynamo).
INTRODUCTION
A flywheel is an energy storage device that uses its significant
moment of inertia to store energy by rotating.Flywheels have
long been used to generate or maintain power and are most
identified with the industrial age and the steam engine.In one
sense it can be thought of as a rechargeable battery that store
energy in the form of mechanical energy instead of electrochemical.
Flywheels have been gaining popularity as a possible replacement
for chemical batteries in vehicles, but until last year there
was no record of a flywheels being used to increase the efficiency
of a bicycle.
In 2011, Maxwell von Stein, a student at Cooper Union, added a
flywheel and a continuously variable transmission to his bike for
his senior project. He used a car flywheel he found that weighs
15 pounds. His idea won him the Nicholas Stefano Prize, which
is Cooper Union’s award for superior mechanical engineering
design. He also gained quite a bit of notoriety on various biking
websites and was featured in NPR’s weekly segment, “Science
Friday.”
2. CLASSIFICATION OF COMPONENTS USED[1]:
FlangeThe flange is where the bearing and the end piece will be
housed. The flange is necessary because it will prevent the line
that the end piece holds from being twisted. The bearing will
take the rotational load so that the clutch (the line) can be successfully
actuated.
FlangecoverThe flange cover will hold the bearing and the end
piece in place. It has a small extruding piece that will be the part
that actually pushes the 90 tooth gear. The hole going through
the center is 100mm in radius, so it is smaller than the end
piece. This will allow the line to go through while still holding
the end piece in place. The outer radius of the end cap is the
same as the flange and has four matching hole to connect the
parts.
Bearing The bearing will rest inside the flange and will be covered
in oil. The purpose of the bearing is to take the torque load from the flange and not transmit it to the end piece to allow for
a successful clutch actuation. The type of bearing used will be
number 6006, which has an outer diameter of 55mm, an inner
diameter of 30mm, and a width of 13mm.
Tooth gear sprocketit is fixed to the back wheel rim of the
bicycle.Tooth sprocketthe sprocket will connect the flywheel
system to the rest of the bike. A chain will connect it to the
crank.
Flywheel (wheel rim)The flywheel is where the energy is stored
from the brake regeneration. A 20 inch diameter bike wheel rim
will be used as the flywheel since it will be smaller than the 26
inchwheels on the bike, is an off the shelf part that is easy to get,
has most of its mass on the outer edge, would be easy to add
weight to ifnecessary, and has a hub that will be easy to attach
to the axle.
Conclusion:
Thus the flywheel bicycle with mobile chargercycle is designed
tested successfully. The output is verified by running the vehicle
& charging the mobile, charging by pedaling action. The following
advantages were seen such as It is more convenient and easier.
It is more eco-friendly. Power is required less to use.
