CHAPTER 1 INTRODUCTION
A sidestand is a device on a bicycle or motorcycle that allows the bike to be kept upright without
leaning against another object or the aid of a person. A kickstand is usually a piece of metal that
flips down from the frame and makes contact with the ground. It is generally located in the
middle of the bike or towards the rear.We may have witnessed motorcycle accidents because of
the surface hindrance of retracted positioned side stand. One of the most common problems that
are encountered in using the side stand is negligence or carelessness to kick back the side stand.
The negligence may be due to absence of mind, urgency, divergence in concentration and few
other reasons, which may prevent the rider to kick back the side stand to its original position
released position!. "ailure to kick back the side stand for any of the reasons stated above may hit
the side stand to surface of road and there by affect the stability of the vehicle and lead to
accident of the vehicle and riders involve in the accident, sometimes fatal. To ensure safety of the
rider, during absence of mind, negligence, urgency or carelessness the side stand lock link helps
in knowing the state of side stand prior to movement of vehicle.
1.1 Types of stands: -
1.1.1 Side stand
A side stand style kickstand is a single leg that simply flips out to one side, usually the non#
drive side, and the bike then leans against it. $ide stands can be mounted to the chain stays
right behind the bottom bracket or to a chain and seat stay near the rear hub. $ide stands
mounted right behind the bottom bracket can be bolted on, either clamping the chain stays, or
to the bracket between them, or welded into place as an integral part of the frame.

1.1." Cent!e stand
A centre stand kickstand is a pair of legs or a bracket that flips straight down and lifts the rear
wheel off the ground when in use. %entre stands can be mounted to the chain stays right behind
the bottom bracket or to the rear dropouts. &any motorcycles feature centre stands in addition to
side stands. The centre stand is advantageous because it takes most of the motorcycle's weight
off its tires for long#term parking, and it allows the user to perform maintenance such as chain
adjustments without the need for an e(ternal stand. %entre stands are found on most )standard)
and )touring) motorcycles, but are omitted on most high#performance sport bikes to save weight
and increase ground clearance.

The side stand lock link relates to the field of automobiles industry, especially for two#wheeler
vehicles using side stand apart from the &ain centre stand provided therein for the resting of the
vehicle. The side stand lock link makes the contact with the gear lever there by indicating the
person handling the vehicle about the unreleased side stand when the rider tries to apply the gear
in unreleased state of stand and prevents him from being endanger or to have unsafe ride of
motorcycle. The *ike $ide stand unfolded ride lock link for two wheelers is the one of the
lifesaving mechanism which prevents the ride from riding the bike in unreleased position
retracted position! of the side stand. This prevents the rider as well the vehicle to lose the center
of gravity by imbalance or surface hindrance due to retracted positionof side stand and thereby
saves life of the rider. The side stand lock link is cheap, rugged and easier to install without
additional installations and fittings. The side stand of a motor bike can be retracted automatically

".#(.S. Ha!ey and A!t! R:- &otorcycles are generally provided with stand for supporting
the motorcycles when they are not in use. The standard usually comprises a bar or rod which is
pivotally attached to the lower portion of the motorcycle frame and is movable to a laterally,
downwardly e(tending position so that the motorcycle can be tilted against and rest upon the bar.
When the motorcycle is in use, the bar is swung upwardly and along the frame so that it will not
interfere with the running of the motorcycle. Often the cyclist neglects to move the standard to
its raised position and when a banked turn is made the standard strikes the ground and causes the
motorcycle to be thrown to the ground, generally with serious conse2uences to both the cyclist
and the motorcycle. *ased on the working prnciple of two#wheeler i.e the power is generated in

to lift the side stand up. When the side stand reaches its limit, the power supply is cut off which
can be identified using a limit switch. &icro controller and driver circuit are responsible for the
direction of rotation of the motor. When the push button is pressed, the polarity of the motor
along with the driver circuit gets reversed. +ence the motor rotates in the opposite direction.
There will also be a limit switch at the original position of side stand before retraction. The
power supply will be stopped as soon as the side stand reach the limiting switch. This technology
can be regarded as the lifesaving one. About - of the accidents takes place due to the

".2 Pintoo P!)apati :- In modern world the living status were developed and developing more
e2uipped. The automobile takes a great part in the development, since it plays one of a major key
in daily life. While automobile is concern two#wheeler i.e. motorcycles and bike! it plays very
important role because it saves the time of traveller by reaching the target place very
faster. &otorcycles are generally provided with stand for supporting the motorcycles when they
are not in use. A motorcycle side stand is a nearly universal method of allowing a motorcycle
rider to park his vehicle unattended easily. If this stand is in the park position while the
motorcycle is ridden through left turn a serious safety ha4ard e(its. A new type side stand which

is automatically retracting side stand is invented to prevent such type of accidents. *ased on the
working principal of two#wheeler i.e., the power is generated in the engine and it transmits
power to the pinion and makes it to rotate. The pinion transmits power to the rear wheel pinion
and makes the vehicle to move!. This is the basic principal followed in all type of two#wheelers,
based on this 7sprocket side stand retrieve system8 is designed because this system works by
getting power from chain drive. In Automatic side stand retrieve system, the side stand
automatically gets retrieved if the rider forgets to lift the side stand while moving the bike. It1s
working is based on the working principle of the two#wheelers. In motor bike power is
transmitted from engine1s pinion to the rear wheel i.e. rotary motion of the pinion makes the
linear motion of the chain. That linear motion of the chain is absorbed by rear wheel1s sprocket
and converted into rotary motion!. That rotary motion of the rear wheel makes the bikes to
move. *ased on this side stand retrieve system is designed. If $procket is kept between the chain
drive, it make the sprocket to rotate. The working of this system is based on the sprocket. It gains
the power from the chain and make specially designed component lifting lever! to rotate. This
rotation incites engaged pushing lever to push the side stand to retrieve. When chain rotates in
anti#clockwise direction the inciter assembly1s sprocket absorbs the power and
rotates in clockwise direction.
".3 '. De$ido* :- Today, &otor cycles are used everywhere in all over the world. 3esigner
should design each and every component in the two wheelers with very at most safe and the
product should be economical. In motor cycles, the side stand plays major roll while the vehicle
is in rest condition. While the driver starting the motor cycle, there may be a possibility of forget
to release the side stand. This will tend to unwanted troubles. To avoid the driver has to ensure
that the side stand is released. $ide stand in two wheelers function the entire weight of the
vehicle when it is parked. They are perfect on 2uick stops when one needs to leave the vehicle
for a short while. They are provided with a spring that pulls it back into position to ensure e(tra
safety. A side stand style kickstand is a single leg that flips out to one side, usually the non#drive
side, and the bike then leans against it. $ide stands can be mounted to the chain stays right
behind the bottom bracket or to a chain and seat stay near the rear hub. $ide stands mounted right
behind the bottom bracket can be bolted on, either clamping the chain stays, or to the bracket
between them, or welded into place as an integral part of the frame. A centre stand kickstand is a

They are provided with a spring that pulls it back into position to ensure e(tra safety. $ometimes
the person who drives the two wheeler may forget to release the side stand. This will tend to
unwanted danger and lack of concentration while driving. 0ow a day1s sensors are used for
ensure that the stand is in released condition or not by indicating it using small lights in stash
board. There is also a possibility to forget to see the light. This research paper focuses on to
completely reduce the possibility of driving two wheelers without releasing the side stand. This
may appropriate for all kind of two wheelers which are driven in gear system with low cost. In
this research paper we are proposing an idea to overcome one of those accidents which take
place due to the non#folding of the bike stand.
".4He$ant Aso :- &otorcycles are generally provided with stand for supporting the motor
cycles when they are not in use .The standard usually comprises a bar or rod which is pivotally
attached to the lower portion of the motor cycle frame and is movable to a late rally, downwardly
e(tending position so that the motor cycle can be tilted against and rest upon the bar .When the
motor cycle is in use the bar is swung upwardly and along the frame so that it will not interfere
with the running of the motor cycle. Often the cyclist neglects to move the standard to its raised
position and when a banked turn is made the standard strikes the ground and causes the motor
cycle to be thrown to the ground, generally with serious conse2uences to both the cyclist and the
motor cycle. In automatic side stand retrieval system, the side stand automatically gets retrieved
if the rider forgets to lift the side stand while moving the bike. Its working is based on the
working principle of the 9# wheelers. In motor bike power is transmitted from engines pinion to
the rear wheel i.e. rotary motion of the pinion makes the linear motion of the chain. That linear
motion of the chain is absorbed by rear wheel sprocket and converted into rotary motion!. That
rotary motion of the rear wheel makes the bikes to move. *ased on this side stand retrieval

system is designed. If sprocket is kept between the chain drive, it makes the sprocket to rotate.
The working of this system is based on the sprocket. It gains the power from the chain and make
specially designed component :ifting lever! to rotate. This rotation incites engaged pushing
lever to push the side stand to retrieve. When chain rotates in anti#clock wise direction the inciter
assembly1s sprocket absorbs the power and rotates in clock wise direction. 7Automatic side stand
system8 will definitely good retrieve system. since the setup is compact it does not affect the
performance of the vehicle. because of the power is obtained from chain drive. 3efinitely this
system could be used in all type of two#wheelers for retrieving the side stand. It will be the major
system to control accidents due side stand problem and protect the careless rider. These system
can be implemented in all types of bikes by changing small variation in si4e and cost of this
system also very low and so it will not affect the economic level also.

3% motor is designed for two speed operation. It consists of three brushes namely; common, low
speed, high speed. Two of the brushes will be supplied for different made of operation. The 3%
motor does not oscillate back and forth, it rotates continuously in one direction like most others
motors. The rotational motion is converted to the back and forth wiper motion by a series of
mechanical linkage. This type of motor is called a gear head or motor end has advantage of
having lots of tor2ue. The dc motor works on

The classic 3% motor design generates an oscillating current in a wound rotor, or armature, with
a split ring commutator,and either a wound or permanent magnet stator. A rotor consists of one
or more coils of wire wound around a core on a shaftE an electrical power source is connected to
the rotor coil through the commutator and its brushes, causing current to flow in it, producing
electromagnetism. The commutator causes the current in the coils to be switched as the rotor
turns, keeping the magnetic poles of the rotor from ever fully aligning with the magnetic poles of
the stator field, so that the rotor never stops like a compass needle does! but rather keeps
rotating indefinitely as long as power is applied and is sufficient for the motor to overcome the
shaft tor2ue load and internal losses due to friction, etc.!
Brushless DC motors
$ome of the problems of the brushed 3% motor are eliminated in the brushless design. In thismotor, the mechanical )rotating switch) or commutatorFbrushgear assembly is replaced by an
e(ternal electronic switch synchronised to the rotor's position. *rushless motors are typically @#

constructed without any iron core. The rotor can take the form of a winding#filled cylinder, or a
self#supporting structure comprising only the magnet wire and the bonding material. The rotor
can fit inside the statormagnetsE a magnetically#soft stationary cylinder inside the rotor provides
a return path for the stator magnetic flu(. A second arrangement has the rotor winding basket

#.1.3 PUSH ;UTTON:
In electrical engineering, a switch is an electrical component that can break an electrical circuit,
interrupting the current or diverting it from one conductor to another. The most familiar form of
switch is a manually operated electromechanical device with one or more sets of electrical
contacts, which are connected to e(ternal circuits. 6ach set of contacts can be in one of two
states; either )closed) meaning the contacts are touching and electricity can flow between them,
or )open), meaning the contacts are separated and the switch is non conducting. The mechanism
actuating the transition between these two states open or closed! can be either a )toggle) flip
switch for continuous )on) or )off)! or )momentary) push#for )on) or push#for )off)! type.

A switch may be directly manipulated by a human as a control signal to a system, such as a
computer keyboard button, or to control power flow in a circuit, such as a light switch.
Automatically operated switches can be used to control the motions of machines, for e(ample, to
indicate that a garage door has reached its full open position or that a machine tool is in a
position to accept another workpiece. $witches may be operated by process variables such as
pressure, temperature, flow, current, voltage, and force, acting as sensors in a process and used to
automatically control a system. "or e(ample, a thermostat is a temperature#operated switch used
to control a heating process. A switch that is operated by another electrical circuit is called a
relay. :arge switches may be remotely operated by a motor drive mechanism. $ome switches are
used to isolate electric power from a system, providing a visible point of isolation that can be
padlocked if necessary to prevent accidental operation of a machine during maintenance, or to
prevent electric shock.
An ideal switch would have no voltage drop when closed, and would have no limits on voltage
or current rating. It would have 4ero rise time and fall time during state changes, and would
change state without )bouncing) between on and off positions. =ractical switches fall short of
this idealE they have resistance, limits on the current and voltage they can handle, finite switching
time, etc. The ideal switch is often used incircuit analysis as it greatly simplifies the system of
e2uationsto be solved, but this can lead to a less accurate solution.
#.1.4 SIDE STAND
A $ide stand is a device on a bicycle or motorcycle that allows the bike to be kept upright
without leaning against another object or the aid of a person. A )smaller, more convenient)
kickstand was developed by 5oseph =aul Treen, the father of former :ouisiana Kovernor, 3ave
Treen. A kickstand is usually apiece of metal that flips down from the frame and makes contact
with the ground. It is generally located in the middle of the bike or towards the rear. $ome
touring bikes have two; one at the rear, and a second in the front.
A side stand style kickstand is a single leg that simply flips out to one side, usually the non#drive
side, and the bike then leans against it. $ide stands can be mounted to the chain stays right
behind the bottom bracket or to a chain and seat stay near the rear hub. $ide stands mounted right

behind the bottom bracket can be bolted on, either clamping the chain stays or to the bracket
between them, or welded into place as an integral part of the frame.

CHAPTER 2 CONC&USION B FUTURE SCOPE
2.1 Con%sion
It will help over the for two#wheelers for safe riding and prevents accidents The automatic sidestand is a very complicated setup and re2uires e(pert knowledge to install. When fitted from
local shops. The operation is dependent upon battery so a powerful battery is must. It doesn1t not
affect the overall running cost and weight of the two wheelers .hence it can be inferred that the
automatic side stands is a very fle(ible system to operate, remarkably support the better stability.
7Automatic side stand system8 will definitely good retrieve system. $ince the setup is compact it
does not affect the performance of the vehicle. *ecause of the power is obtained from chain
drive. 3efinitely this system could be used in all type of two#wheelers Tvs#P:, all front,
back,hand geared! for retrieving the side stand, it will be the major system to control accidents
due side stand problem and protect the careless rider. This system can be implemented in all
types of bikes by changing small variation in si4e and cost of this system also very low and so it
will not affect the economic level also.
Automatic stand is presently in use and 2uite successful. Although it has certain disadvantages.
9! And secondly the stand is not engage with road by the use of push button.
A motorcycle side stand is nearly universal method of allowing a motorcycle rider to park his
vehicle easily. If this stand is in the park position while the motorcycle is ridden through left turn
a serious ha4ard e(ists. A new type stand side stand which is automatically retracting side stand
is invented to prevent such type of accidents. $ide stand mounted behind bottom bracket and can
be bolted on either clamping the chain stays, or welded in to place as an integral part of the
frame.
We are working to remove this two disadvantages. "or removing these two disadvantages we use
the speed sensor and microcontroller and push button, when bike take some /=& then the sensor
sense the signal and sends to the microcontroller and according to the % programming the
microcontroller actuate the 3% motor, and the dc motor automatically disengage the side stand
from the road. Through this arrangement the both disadvantages are removed.

The project has come out as a grand success. We learn more and more in our project. It is
different e(perience to our self we well. $uccessfully finish the project. We well to step by step
testing in that. /esult all so very well. This project is useful for all the peoples.
2." Ft!e S%ope
This is an new and revolutionary techni2ue in the world of automation. It enhance the safety of
rider life and reduce road accidental probability. This techni2ue is to inplement in all two
wheelers for human life safety. "or a careless rider, its usual mistake to remove side stand and it
leads to something wrongmiss happening!. We can implement this and reduce a factor of
accidents
