This is how the transmission got named ‘Continuous Variable Transmission’. Since both pulleys have the moveable conical plate, the diameter of both can be continuously changed and the vehicle can run on a variety of diameter ratios between the driving and driven pulley. The movable conical plate moves closer or farther from the opposite one to increase or decrease the diametrical rotation of the belt. In both the pulleys, one conical plate is stationary and the opposite one is axially movable. This pulley arrangement can be described as two opposed conical plates, conically-inward with a belt running over their joining. One pulley is connected to the engine and another to the differential that rotates the wheels. Instead of the gearbox, the continuous variable transmission consists of a set of two cone-pulleys connected by a belt. If the car accelerates the computer will automatically disengage the clutch connected to the shaft with odd-numbered gears (3rd) and engage the clutch connected to the shaft with even-numbered gears, on which it had already kept the 4 th gear preselected. For example, if the car is running in 3 rd gear, the sensor-linked computer will predict the next-needed gear that could be either 4 th or 2 nd on the subsequent shaft. The gears mounted on these shafts remain meshed with loosely-mounted gears (independent) on the output shaft which provides rotation to the wheels.Īs the output shaft runs on a selected gear ratio, the sensors predict the next gear ratio calibrating the speed, engine speed, and acceleration or retardation. One shaft has even gears while the other has odd ones. The inside shaft extends out of the length of the outside one and has some gears mounted on it, as does the outside shaft. Both sensor-based clutches are respectively linked to two cylindrical shafts, which are placed concentrically (one encases another) and are independent of each other. Since both transmissions determine the ride quality and also how economical running your car will be, let’s learn what distinguishes them.Īs the name suggests, dual-clutch transmission functions with two clutches that are operated automatically. This is due to the smooth and pocket-friendly ride experience they provide. In India, dual-clutch transmission (DCT) and continuous variable transmission (CVT) are two fairly popular automatic transmissions. But today, automatic transmissions are a common fixture in our cars for the convenience they provide in Indian driving conditions. So, you pressed the clutch pedal twice for shifting one gear. Double-clutching meant that to engage another gear while driving, you had to first shift into neutral and then shift to the desired gear. There was a time when ‘double-clutching’ was the norm. Transmission, in particular, has undergone major evolution. The automotive industry has seen a sea change in the last few decades.
