Contact Home Driveline Additives Continuously Variable Transmission (CVT) Continuously Variable Transmission (CVT) Afton’s CVT transmission fluid additives deliver superior friction control, anti-wear protection and oxidation control for belt and chain technologies. Continuously variable transmissions (CVT) change steplessly through an infinite number of effective gear ratios. This differs from other mechanical transmissions that only allow a few distinct gear ratios to be selected. There are no gears to create gear ratios in a CVT transmission. Instead the design typically involves two pairs of cones mounted on shafts. Each pair of cones acts like a pulley system. When the cones move together, they create a larger diameter pulley, and a smaller diameter pulley when moving apart. Because the pulleys can be any diameter in relation to each other, the number of ratios is effectively infinite. This flexibility within the CVT design can provide better transmission response and fuel economy over other transmissions by enabling the engine to consistently run at its most efficient revolutions per minute (RPM) for a range of vehicle speeds. The challenge for a CVT additive is different from that of a step-type automatic transmission (AT). Step ATs employ friction plates with paper (cellulose) friction material. Whereas CVTs have a steel-to-steel interface requiring different friction properties, strong wear protection and high film strength. Afton Chemical CVT transmission fluid additives provide superior friction control and anti-wear protection, as well as industry-leading oxidation control, for belt and chain technologies. Why Afton? We have multiple ongoing development programs based on collaborative global OEM partnerships. Our exciting new technology based on our unrivalled expertise in friction control. Our CVT additives are suitable for all CVT designs – both push-belt and chain CVTs. Our additives deliver improved friction stability and fill-for-life performance. Was this content helpful?
