Introduction to CVT Transmission

Continuously Variable Transmission (CVT) technology represents a significant advancement in automatic transmission design, offering a unique approach to power delivery. Unlike traditional automatic transmissions with a fixed number of gears, a CVT smoothly adjusts the ratio between engine output and wheel speed, leading to enhanced fuel efficiency and a generally smoother driving experience. This technology is increasingly popular in various vehicles, especially those emphasizing fuel economy and performance.The fundamental principle behind CVT operation is the use of two variable-diameter pulleys, typically made of durable materials like steel or composite materials, linked by a belt.

These pulleys are connected and their diameters are altered to provide a continuous range of gear ratios. The varying pulley diameters allow for a continuous power transmission ratio, unlike the discrete steps in traditional transmissions. This continuous variation enables the transmission to optimize engine speed for any given road condition, improving fuel efficiency and responsiveness.

CVT Design Types
