ABSTRACT: In these days’ people concentrate more and more on the comfort and operability of automobiles. Four wheel-drives in cars have become popular and are in demand in the automotive sector. But the advancement in two wheelers was limited. The concept of two-wheel drive motorcycles was not successfully and economically implemented. Two-wheel drive motorcycle is desirable in situations where there is rough terrain and high inclination roads which are tiresome and difficult to drive with the conventional rear wheel driven motorcycles. The two-wheel drive bikes are apt for farmers, military applications, desert drive etc. The proposed design provides economical and user friendly two-wheel drive. The use of chain drive and sprockets help in reduction of power loss during transmission of power from the engine to front and rear wheels. The lightweight ‘all-mechanical system’ is used to obtain two wheel-drive. Under optimum traction conditions, the rear wheel is actually driving faster than the front wheel and the one-way clutch within the system allow the front wheel to freewheel under these conditions. At this point, the two-wheel drive system is effectively passive. Though the front drive system is turning, it is not actually transferring power to the front wheel. When the rear wheel loses traction, the drive ratio, relative to your forward speed, changes. The two-wheel drive system engages transferring power to the front wheel until traction is re-established at the rear wheel. This project is modelling and fabrication of electrical driven 2-wheel drive in motor cycle. With the help of an external electric source the front wheel is provided power from a hub motor.
