Automobile: why dont a differential is used in three wheelers

why dont a differential is used in three wheelers?????
i have seen many autos in which no differetial is used just a bevel gear assembly is used which trasmits power to the two wheels at 90 degrees.

There is of course a differential but not in the conventional form. only one of the rear wheels gets power from the engine. The other one is free to rotate. that makes them independent of one another and thus taking turns is no problem. The same applies to cycle rickshaws.

There is a different principal here. One of the rear wheel is free to rotate and the other is driven by the engine. So both the wheel rotate at the required respective RPM while cornering.
I am a third year student and i am doing an individual project of three wheeler,
My project mainly based on a used three wheeler which has two stroke engine. I have to remove the engine and place a proper motor, differential shaft to the rear part of that three wheeler. I have no idea about that, Can any body please help me...

what exactly is your project??what ideas you have??

Design and fabrication and testing of differential gear unit for an electrical three wheeler ..
1. understanding of the traction torque characteristics in different driving conditions
2. understand the traction motor characteristics
3. design of the compatible coupling (differential unit)

I have been provided an old three wheeler which running from two stroke engine. But it doesn't in the running conditions. So my supervisor asked me to remove the engine and replace a suitable motor and make a electrical three wheeler. Actually my target should be calculate and fabricate proper differential shaft. Although select a proper traction motor to run the electrical three wheeler.

Challenging project!
You should calculate on the torque requirements of the 3-wheeler. Try finding gear ratios/design of Tata Ace or similar pick-ups. You could reassemble the differential of similar vehicle and mate with an electric traction motor (DC Motor). I think traction motor is a bit costly affair.
Basically, designing/fabricating a differential system is way too complicated and technical knowledge is required. You study thoroughly the existing systems in vehicles (Light Commercial Vehicles) as a start-off.
Good Luck!
