Planetary Gear Set
Definition of Planetary Gear Set as it relates to Automotive, Automotive Transmissions, Drivetrain
A Continuously Variable Transmission (CVT) is a type of automatic transmission used in automotive drivetrains that can seamlessly change through an infinite number of gear ratios. This enables the engine to run at its most efficient speed, thereby optimizing fuel efficiency and performance. CVTs utilize a belt or chain running between two variable-diameter pulleys to achieve this smooth transition between ratios, resulting in a more consistent driving experience compared to traditional stepped automatic or manual transmissions.
