📖 Design and Development of Single Ball Traction Drive for CVT..

Traction drive system has been used for various purposes and in various environments. Mainly Traction drive is used for CVT (Continuously Variable Transmission) applications. Traction drive systems can be alternative to the gearing system. The advantage of Traction drive is the smooth traction surfaces that provide more variability ratio and capability for higher and lower speeds than gears. Transmission systems provide speed and torque conversions from a rotating power source to another device. Mechanically a transmission system in an automotive application is complex and is required to disconnect and connect the engine drive train from the wheels as required. To reduce the rotational speed of the engine and vary the transmission gear ratio as required by the driver to match the torque demanded at the wheels. Hence the efficient transmission of power from the engine to the wheels of an automotive vehicle is one of the greatest challenges facing automotive engineers.
