car serpentine belt

To enhance the strength and durability of timing belts, manufacturers often incorporate reinforcement materials such as fiberglass or aramid fibers (e.g., Kevlar). These reinforcements prevent elongation and ensure that the belt maintains its shape under tension. Fiberglass is commonly used for its high tensile strength and ease of manufacturing, while aramid fibers are known for their impressive heat resistance and toughness. Using these materials in timing belts results in better performance under high-load conditions, reducing the likelihood of belt failure.

A CVT transmission belt, also known as a drive belt or variator belt, is a unique belt that plays a pivotal role in the operation of a continuously variable transmission. Unlike traditional automatic or manual transmissions that use fixed gear ratios, a CVT can adjust the ratio infinitely within a given range. This capability is primarily achieved through the movement and tension of the CVT belt, which connects two pulleys—the primary pulley and the secondary pulley.
