The efficacy of an endless flat drive belt depends largely on its design and the materials used in its construction. Typically made of fabrics like cotton or polyester, which are then coated with rubber or synthetic compounds, these belts are engineered to withstand substantial tension and provide flexibility. The choice of material significantly impacts the belt's performance, including its durability, grip, and resistance to environmental factors such as temperature and humidity.

In a CVT system, the transmission belt operates between two pulleys that can change diameter. As the engine generates power, the primary pulley expands and contracts, causing the belt to move up and down its sides. This movement adjusts the gear ratio according to the vehicle's speed and engine load, allowing for optimal engine performance and efficiency at all times. The belt's ability to flex and adapt is what makes the CVT smooth and responsive, eliminating the shift shock commonly experienced in traditional transmissions.
