This document proposes a mechanical system to automatically retract a motorcycle's side stand when the vehicle starts moving. The system uses a small sprocket connected to the bike's drive chain to power a lever that lifts the side stand. It is a simple, low-cost design that does not require external power or electronics. The proposed side stand retrieval system could improve safety by preventing accidents caused when riders forget to raise the side stand before driving.

3. TITLE:

4.  In modern developing world, automobile plays
important role especially two-wheeler i.e.
motorcycle & bicycle.
 While automobile is concern two-wheeler
i.e,(motorcycles and bike) it plays very important
role because it saves the time of traveler by
reaching the target place very faster. Although it
saves the time it does not safe the life of rider if
rider is careless.
 While the two-wheelers is concerned accidents
occurs due to riding the vehicle in high speed,
ignores to use helmets, does not maintains the
speed limit and forgets to lift the side stand
while riding the vehicles.

5.  About 13 people die every hour due to automobile
accidents in India.
About 36% of these accidents are due to
negligence in lifting the side stands.
 We have developed a mechanical arrangement
which will cause the side stand to retrieve
automatically as the vehicle starts to move.
 This system can be attached in all types of two-wheeler
(moped, geared, non-geared, hand
geared bikes) and it is designed based on the
working principle of bikes.

6.  General idea:
 A small flat rod is attached and pivoted between
the gear actuator lever and the side stand of the
bike. When the gear is actuated the side stand
gets lifted.
Small stepper motor is connected between the
side stand and the engine, when the engine is
started the stepper motor runs and retrieves the
sides stand automatically.

7.  CONSTRUCTION:
The whole construction of this system is
simple and efficient. The arrangement and
position of components makes the system to
function. Each and every component has its
own property and responsibility. The power
obtained from the chain drive is transmitted to
the appropriate component without power loss.
The systematic design of system is made in
order to consume only very low amount of
power initially for few seconds to retrieve the
stand. Then the power consumption does not
occur after retrieving the stand.

9.  PARTS:
 Pivot
 Pushing lever
 Axle
 Sprocket (2 no’s – driver and pinion )
 Ratchet wheel
 Lifting lever
 Box clamp & stand.
 Spring
 Pivot

10. MATERIALS ESTIMATED COST(Rs)
SPROCKET 2 NOS 300
WHEEL CHAIN 200
SIDE STAND AND BOLTS 250
MS RODS (LIFTING, PUSHING
RODS)
500
PEDAL 150
WELDING COST 300
TOTAL 1700

11.  TYPES OF EXISTING SIDE-STAND :
 MANUAL STAND
 Manually operated
 STANDS WITH INDICATORS Indicate position of
Side-stand
 STANDS WITH SPRINGS Retraction caused by
spring
DISADVANTAGES OF EXISTING SIDE-STANDS :
Accident prone
Maximum Fatigue
Only indicate the position
Expensive
To be imported – (Fully Automatic Stands)

12.  Advantages:
a. Simple mechanism
b. No need external source
c. No electronic control required
d. Customer safety
e. Can form as a ‘Standard Feature’
f. Marginal increase in cost
g. Improved sales : To face competition.
h. Ergonomic friendly
i. Low maintenance : Can be repaired locally


13. CONCLUSION
“ Sprocket- side stand retrieve system” will definitely
good retrieve system. since the setup is compact it
does not affect the performance of the vehicle. because
the power is obtained from chain drive.
 Definitely this system could be used in all type of two-wheelers
for retrieving the side stand.
 This system can be implemented in all types of bikes by
varying size and cost of this system also very low also,
while compare to other system this SPROCKET SIDE
STAND RETRIEVE SYSTEM will be the life saver.
