Paper Details

In recent years there has been an immense increase of interest in hybrid vehicles over diesel or petrol vehicles given theirlow exhaust emission, lesser noise and lower fuel consumption. Hybrid vehicles have a bright future in India given theincrease in pollution caused by the rapidly rising number of automobiles used by general public. A hybrid vehicle consist oftwo power sources i.e. 1) - engine 2)- battery(ultra-capacitor, super capacitor etc. can also be used as optional powerresources). The motor and engine are generally coupled with a set of planetary gears which transfers the power output ofmotor and engine to the differential with some mechanical energy losses. This paper describes a new type of coupling systemwhich can be used in hybrid cars while completely removing the necessity of using planetary gear sets and transfer of powercan be done directly to the differential and then to the wheels and thereby eradicating mechanical energy losses caused bythe planetary gear sets and at the same time saves the effort to design and fabricate them. The onboard charging systemusing Torsen Differential and engine will not only eliminate the necessity of availability of electric charging stations atvarious locations but also reduces the time spent for charging of batteries. The coupling system was designed in SolidWorksand simulations were done to verify the proposed concept. The calculations were done by choosing an average passenger carand the coupling system was designed accordingly. The simulation results verified that the proposed system could be easilyused in hybrid cars.
