Does Continuously Variable Transmission Mean Automatic Transmission?
1 Answers
Continuously variable transmission is a gearbox without discrete gear ratios, meaning it has no fixed gear positions. Working principle of continuously variable transmission: It works by wrapping both ends of a transmission belt around a conical pulley, where the outer diameter of the pulley changes continuously via hydraulic pressure. During startup, the driving pulley's diameter becomes the smallest while the driven pulley's becomes the largest, achieving a higher transmission ratio. Function of continuously variable transmission: Continuously variable transmission refers to a system that can continuously obtain any transmission ratio within its range. It enables optimal matching between the drivetrain and engine operating conditions. Common types include hydro-mechanical CVT, metal belt CVT (VDT-CVT), and variable-angle CVT.
