Button Operated Gear Shifting System Of Two Wheeler Using Electromagnets Electroma gnets
1.Astract! In this study, a gear shifting mechanism is designed and applied to make the shifting process faster and less destructible for the driver. The new device must be reliable, low construction and maintenance cost. This paper aims to improve gear shifting process using the electromagnets, gears, bearings, iron discs, springs. According to this gear shifting method, a person could change the gears with the help of buttons. buttons. In this study, a gear shifting mechanism was designed and applied on an auto clutch featured bike to make the gear transmission process faster and less destructible for the two wheelers. The present automatic transmission costs very high and it is not suitable for small displacement engines i.e. two wheelers. This new device must be reliable, has small dimensions, economical and low maintenance cost. This project aims to improve the gear shifting process with a suitable control mechanism to implement in electromagnetic clutch featured bikes. But the gear transmission mechanism designed makes driving easier and to achieve efficient driving. and changing gears with buttons gives totally new experience to the driver .
".#ntroduction! In this project, we tried to shift the gears in the two wheeler with the help of buttons .This could be done by the use of electromagnets .e used electromagnets which attracts the gears and helps in the meshing of gears.
".1.Electromagnet! An electromagnet is a magnet that runs on electricity. !nlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity. An electromagnet works because an electric current produces a magnetic field. The magnetic field produced by an electric current forms circles around the electric current. An electric current flowing in a wire creates a magnetic field around the wire, due to Ampere"s law. law. To concentrate the magnetic field, in an electromagnet the wire is wound into a coil with coil with many turns of wire lying side by side. The magnetic field of all the turns of wire passes through the center of the coil, creating a strong magnetic field there. A coil forming the shape of a straight tube is called a solenoid. solenoid.
The magnetic field of electromagnets in the general case is given by Ampere"s #aw$
which says that the integral of the magneti%ing field & around any closed loop of the field is e'ual to the sum of the current flowing through the loop. e use air conditioner compressor(s electromagnets, which are used in the cars, for our experiment or project as this could be easy to use in the gear shifting.
$.%escription e are just trying to make out some arrangement using electromagnets to get our project working. In our project, we mainly used$
) electromagnets bearing system, which is used in the car air conditioner(s compressor, to engage the gears. )Two shafts on which the gears are mounted on first one and electromagnets, bearings, iron discs, gears are mounted on the other one.
)*+ motor which helps in rotating the first shaft. )Iron disc which will attract towards the electromagnets when the button is pressed. )springs which will help in disengaging the gears when power is cutoff. )Buttons helps in changing the gears in accordance with the re'uirement.
&.Operational 'echanism! The arrangement of all the parts are shown in the figure and the operational mechanism of the project is as follow$ ne shaft , which contains the - gears , is fixed at one end which keeps on rotating as the motor starts. And the other shaft contains the - gears attached with the iron discs along with the electromagnets. The gears on the second shaft is attached with the iron disc by means of the springs which helps in the disengaging of the gears. In this gear shifting apparatus a force device is also provided, that preferably includes a spring, which now forces the shift sleeve into a position spaced away from the gear. The electromagnets are fixed on the bearings which are further attached with the buttons.

4ow, for the working of the project, one of the shaft is keep on rotating when the we start the motor. ith that shaft all the gears also rotates. To engage the gears, when we press the button the electromagnet start functioning and attracting the iron disc due to which the gear attached with the iron disc come towards the electromagnet and engaged with the gear of first shaft.
*uring this operation, the spring will contracts. The electromagnet is attached with the bearing due to which gears keeps on rotating even after meshing. And for the disengaging of the gears, the contracted spring will help out. As the power is cut off for the electromagnet, so the functioning of electromagnet is done by this and the contracted spring will let back the gear to its original position. 3imilarly, it is done for the other gears also. In order to bring the gear shifting apparatus into the neutral condition, the coil of the electromagnet is not supplied with electric current. &ence the gear shifting apparatus is brought into its neutral condition simply by interrupting the current flow through the electromagnet

(.)esult and %iscussion! )As we had put all of our effort on making our project working and it finds to be little complicated while assembling but we get success at the end. All the parts are properly fitted so that the gears could possibly meet each other. As you can see from the figure that all parts are properly fitted with nut and bolts. It works according to our desires and needs.
)3uitable for virtually any kind of riding, whether you are looking for the fast change for racing, comfort and convenience when cruising, or whether you have any disability preventing you from changing the gear with your foot. )It re'uires the simple maintainance care. )1epairing and replacement of the parts are easy. )2asy to operate and the driver find their vehicle convenient to use and gives totally new experience to the driver. ) It is basically beneficial model for handicapped person as they can shift gears with the help
of buttons by their hands.
