automatic gear changer using two wheeler speed changer
DESCRIPTION
this project is used in driving applications in traffic areas when the gear changes depends upon the vehicle speedTRANSCRIPT
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.
