Continuous variable transmission differs from automated manual transmission, which can seamlessly change through an infinite number of effective gear ratios between maximum and minimum values. It is a clutchless gearbox but in some applications, a centrifugal clutch is added to ease neutral stance. It consists of a belt that rotates and slides between two tapered drums as you accelerate the vehicle, The belt begins to rotate on the drums and, at the same time, to slide on the drums from one side to the other. This decides the drive to a driven ratio of torque which further varies the speed of the vehicle. It delivers a constant acceleration from a complete stop to cruising speed with the ability provide to set the operating point, an engine can be run to provide the maximum fuel efficiency. Let us have a deep insight into the pros and cons of continuous variable transmission (CVT) in this article.
Advantages of continuous variable transmission :
- Vehicle weight is reduced.
- To provide smooth operation.
- The efficiency of the engine is increased since there is no repetitive engagement and disengagement of the power from the engine.
- To provide quick acceleration.
Disadvantages of continuous variable transmission :
- This transmission may affect the performance and life of the belt since there is an initial slip in the transmission belt.
- There will be a speed limit.
- The cost of CVT is high as compared with AMT is the reason why car makers are not putting in entry-level hatchbacks and small cars.
- The cost of the transmission belt is high.
