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

by using a motor and shaft circuit controlled by a driver circuit. The power supply can be given

either by an e(ternal source like batteries or by internal power sources. The side stand of a motor

bike is connected with the motor using a shaft. This motor is driven and controlled by a driver

circuit and a micro controller. The rotation of the side stand and motion of the motor is controlled

by the driver circuit which was internally connected with the motor. The motion of the side stand

is monitored by a limiting switch . When the starter button is pressed the motor rotates in a

direction 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.

".#(.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

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 principle followed in

all types of two#wheelers, based on this 7automatic side stand retrieve system8 works.

"./ +a0io :- The side stand of a motor bike can be retracted automatically by using a motor

and shaft circuit controlled by a driver circuit. The power supply can be given either by an

e(ternal source like batteries or by internal power sources. The side stand of a motor bike is

connected with the motor using a shaft. This motor is driven and controlled by a driver circuit

and a micro controller. The rotation of the side stand and motion of the motor is controlled by the

driver circuit which was internally connected with the motor. The motion of the side stand is

monitored by a limiting switch. When the starter button is pressed the motor rotates in a direction

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

carelessness of this sort. $afety is the first and foremost motivation behind this system.

/eduction of human work can also be achieved by this system. The cost and maintenance of the

system is also economical. Our concept is to lift the side stand of a motor bike automatically with

the help of a motor and a shaft arrangement using a controller circuits like micro controller or

stopper circuits. This automatic technology is applicable to all the two wheelers with self#starting

facility. In those two wheelers without self#starting facility, a separate power source can be given

to apply this technology. This technology is most important because of the number of accidents

take place because of %arelessness is very high. $o it is essential to have a system to nullify this

effect.

".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


9/26

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

pair of legs or a bracket that flips straight down and lifts the rear wheel off the ground when in

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

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.

across a conductor which is e(posed to time varying magnetic fields. %ommonly, transformers

are used to increase or decrease the voltages of alternating current in electric power applications.

A varying current in the transformer's primary winding creates a varying magnetic flu( in the

transformer core and a varying magnetic field impinging on the transformer's secondary winding.

This varying magnetic field at the secondary winding induces a varying electromotive force

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


18/26

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 @#

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
