ABSTRACT: in modern developing world, automobile plays important role especially two-wheeler i.e. (motorcycle & bicycle) plays a major role. Even though they are helpful there are some sad events like accidents due to carelessness of riders. Major accidents occur due to forgetting of lifting the side stand. To rectify this problem many advance measure have taken, but they are useless. So as a by considering that it should be implemented practically in all types bikes the new system “AUTOMATIC SPROCKET SIDE STAND RETRIVE SYSTEM ’’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.
Since all bikes transmit power from engine to rear wheel by means of chain transmission system, we are going to affix extra gear to achieve this type of mechanism for safety.
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.
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.
PARTS:
1. Pivot
2. Pushing lever
3. Axle
4. Sprocket (2 no’s – driver and pinion )
5. Rachet wheel
6. Lifting lever
7. Box clamp &
