What does the CVT continuously variable transmission on a car refer to?

[EmiliaMarie]

CVT continuously variable transmission does not have specific fixed gears. The following is an introduction to CVT: 1. In the CVT transmission system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley actually consists of two conical discs forming a V-shaped structure. The engine shaft connects to the small pulley, which drives the large pulley through the steel belt. 2. The construction of CVT transmission pulleys is quite unique, divided into movable left and right halves that can move closer together or apart. The conical discs can tighten or expand under hydraulic pressure, squeezing the steel belt to adjust the width of the V-shaped groove. When the conical discs move inward and tighten, the steel belt is pushed outward from the center of the pulley; conversely, it moves inward toward the center. 3. Theoretically, the CVT transmission system can have an unlimited number of gears, allowing for more flexible gear settings.
