Variable Variable Transmission (CVT)
A continuously variable transmission (CVT) is a type of automatic transmission that uses two bevel pulleys connected by a belt or chain to provide a continuous range of gear ratios.
How does CVT work:
* The motor is connected to the CVT input pulley.
* The output pulley is connected to the drive wheels.
* Cone-shaped pulleys expand and contract to adjust the effective diameter of the pulleys.
* When the diameter of the pulleys changes, the gear ratio between the input and output shafts changes.
* The belt or chain slides over the pulleys, providing a smooth and continuous change in gear ratio.
Advantages of CVT:
* Smooth Gear Shifting: CVT provides smooth and continuously variable gear shifting without sudden jerks or jerks.
* Optimum Fuel Economy: CVT can maintain optimal engine speed at all times for better fuel efficiency.
* Compact and lightweight: CVTs are typically smaller and lighter than other automatic transmissions.
* Low noise and vibration: With smooth gear shifting, the CVT provides low noise and vibration.
Disadvantages of CVT:
*Limited towing capacity: CVTs are typically rated to have less towing capacity than traditional automatic transmissions.
* Increased wear under hard acceleration: CVT belts or chains may experience increased wear under hard acceleration or towing.
*Higher maintenance costs: CVTs can be more expensive to maintain than other automatic transmissions.
Common CVT applications:
* Small and medium cars
* Hybrid and electric vehicles
* Scooters and motorcycles
