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.

Cogged belts are typically constructed from flexible materials such as rubber or thermoplastic elastomers, often reinforced with fibers like fiberglass or polyester to enhance their strength and durability. The notches in the belt serve multiple functions they reduce the belt's bending radius, decrease weight, and provide a larger surface area for grip. The precise tooth spacing and design are engineered to ensure that the belt remains engaged with the pulleys throughout its rotation, even under varying loads.
