Performance Investigation of A Controlled Differential Continuously Variable Drive

Now a day's development trends in car industry and mobile machines are driven by universal concerns on energy limitations and greenhouse gases reduction, more energy efficient and environmentally friendly vehicles will be needed. As the increasing concerns in the impact of vehicle emissions of carbon dioxidesand Nitrogen oxides on the biosphere combined with today's shortage fuel, hence need to find alternate fuel solutions or develop the transmission system in such a way that lower consumption and lower emission should takes place. Continuously variable drive is the type of automatic transmission that allows selection of infinite number of transmission ratios within the finite range i.e. between minimum and maximum value. Continuously variable drive is 34.91% more efficient than that of manual transmission. In order to achieve emission reduction and fuel economy needs to improve fuel efficiency. Continuously variable drive can be improved by coupling differential gear assembly to one of variable speed drives; we can increase the speed variation range at the expense of the horse power range. Numerous combinations of the variables are possible
