AUTOMATIC GEAR CHANGER USING TWO WHEELER SPEED

CHANGER

ABSTRACT

• The Automatic gear changer system is used to change the gear in a tensionless manner. In this system a fuel power is not required to change the gear. So, that the human energy will not be wasted.

• The system consists of a battery electronics control board, soft gear mechanism through which the signals are given to the control board which with control the motor which will in turn change the hard gear. Thus the soft hand gear system for two wheelers work.

• The gear changing motor which is a stepper motor will rotate according to the gear required. The electronic control board makes all the controls in the system

INTRODUCTION

• An automatic (also called automatic gearbox, or auto transmission) is one type of motor vehicle transmission that can automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually.

• Most automatic transmissions have a defined set of gear ranges, often with a parking pawl feature that locks the output shaft of the transmission.

WORKING PRINCIPLE • The Automatic gear changer system is used to

change the gear in a tensionless manner.• In this system a fuel power is not required to change the

gear. So, that the human energy will not be wasted. • The system consists of a battery electronics control

board, soft gear mechanism through which the signals are given to the control board which with control the motor which will in turn change the hard gear. Thus the soft hand gear system for two wheelers work.

• The gear changing motor which is a stepper motor will rotate according to the gear required. The electronic control board makes all the controls in the system

TYPES OF TRANSMISSION

• MANUAL TRANSMISSION

• A manual transmission or sequential type is a type of transmission used on motorcycles and cars, where gears are selected in order, and direct access to specific gears is not possible.

• AUTOMATIC TRANSMISSION:

An automatic transmission is one type of motor vehicle transmission that can

automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually and to achieve efficient driving.
