Transmission CVT (Continuously Variable Transmission)
A CVT, or CVT, is a type of automatic transmission that provides smooth and continuously variable transmission ratios. Unlike conventional fixed-gear automatic transmissions, the CVT’s gear ratio can vary smoothly over a specified range.
How does CVT work?
A CVT consists of two tapered pulleys (variators) connected by a flexible metal belt or chain. One pulley is connected to the engine and the other to the transmission.
When the driver presses the gas pedal, the engine transmits power to the input CVT. The variator expands, increasing the radius, and the output variator narrows, decreasing the radius. This change in radius changes the gear ratio, effectively changing the speed and torque on the output shaft.
Advantages of CVT
* Smooth Gear Shifting: The CVT provides continuously variable gear ratios, eliminating jerks and jerks during gear changes.
* Maximum efficiency: The CVT always selects the optimal gear ratio for the current driving conditions, resulting in the best possible fuel economy and performance.
* Compact: CVT transmissions are typically more compact than conventional automatic transmissions, freeing up space in the engine compartment.
Disadvantages of CVT
* Limited torque: CVTs cannot handle as much torque as traditional automatic transmissions, limiting their use in high-performance vehicles.
*Increased noise: CVT belts or chains may whine at high engine speeds.
*Durability: CVT transmissions have lower durability than conventional automatic transmissions, especially in rough driving conditions.
