What does CVT transmission fluid mean?
1 Answers
CVT transmission fluid refers to the fluid used in a Continuously Variable Transmission. A CVT transmission is a type of automatic transmission where the gear ratio is not a fixed set of discrete steps but a continuous range of values, providing excellent fuel economy, power performance, and smooth driving experience while reducing emissions and costs. Characteristics of the transmission: The gear ratio is not a fixed set of discrete steps but a continuous range of values, for example, it can vary from 3.455 to 0.85. The structure of a CVT is simpler and more compact than a traditional transmission. It does not have the numerous gear pairs of a manual transmission or the complex planetary gear sets of an automatic transmission. Instead, it relies mainly on primary and secondary pulleys and a metal belt to achieve continuously variable gear ratios. How the transmission works: Unlike a conventional transmission, which uses multiple gear sets of varying sizes that engage and disengage to create different gear ratios, a CVT operates similarly to a bicycle's pedal system, where the chain drives the wheel at different speeds via large and small sprockets. The varying force applied to the gear sets results in different thrust levels, causing the transmission's output speed to change accordingly, enabling smooth, stepless rotation without distinct gear shifts.
