Designing Continuously Variable Transmission for All-Terrain-Vehicle- A Review

Continuously new developments in gear reduction and manufacturing have led tomore robust CVTs, which allows them to be used in more automotive applications. CVTs uses variable adjustable drive ratios instead of discrete gears to obtain optimal engine performance. As CVT development proceeds, costs will be reduced timely and performance will always going to increase which makes further development and application more desirable. CVTs are also being developed in connection with hybrid electric vehicles. Regarding paper evaluates the advantages of CVTs over manual transmission and gives the detailed design of the components of CVT. The CVTs are not new for automotive world, but their torque capabilities and reliability have been limited in past. For good automotive fuel economy and emissions, the continuously variable transmission, or CVT, becomes a key technology by improving the fuel efficiency of automobiles with internal combustion (IC) engines. When the engine runs at the more efficient number of revolutions per minute in case of the given vehicle speed, CVT equipped vehicles maintain better gas mileage and acceleration compared to cars with traditional transmissions
