Paper Title
Automatic Transmission System For Motorcycles

Abstract
It is observed that, in an automobile system the manual transmission is more difficult to learn and it requires frequent shift between gears especially while driving in cities. Each time it requires engaging and disengaging clutch while shifting gears. This is a tiresome task. In order to make this task easier, automatic transmission is evolved. Incorporating a lockup mechanism and start clutch for even more compactness and improved efficiency. As well as the automatic transmission system achieving some goals such as, � Highly efficient torque transmission due to mechanical transmission in parallel with hydraulic transmission. � Simple system configuration and high level of controllability. � Compact unit increasing machine design freedom. Index Terms- Automatic transmission, Swash plate, Distributor valve, ECU, Lockup mechanism, Start clutch.
