Automatic Transmission Vehicle Using Infinitely Variable Transmission

In conventional transmission system generally use of friction clutch and gear box. It required hydraulic fluid and costly lubrication as well as cooling method's resulting higher operating cost and more power losses, by eliminating the gear box and clutch from the automobile system, it makes transmission system automatic. The drive use in transmission system is lestran drive. It is also known as infinitely variable transmission. It produce eccentricity between lobe which is turned transmit the power to yoke and from yoke the power is transmitted to unidirectional clutch to the final drive. An Infinitely variable transmission provides continuously variable speed and torque ratios, depending on the input and output speeds. The drive gives variation in torque and motion from zero to infinity and also increases transmission efficiency. The small no of parts and the state forward parts design drive reduces manufacturing cost in both material and labor and also increases reliability. The advantages using the drive are by eliminating the gear box and friction clutch, reduces the driving stresses and also increases the efficiency of drive considerably.
