A cvt transmission is totally different from any other automatic transmission because. In a nutshell a continuously variable transmission or cvt doesn t offer fixed gear ratios like a either a manual gearbox automatic transmission or a dsg direct sequential gearbox a newer type of auto.
A cvt or continuously variable transmission seamlessly changes through an unending range of effective gear ratios while you drive whereas other kinds of mechanical transmissions offer a fixed.
What is a cvt transmission and how does it work. Most cvts only have three basic components. A continuously variable transmission cvt is an automatic transmission that can change seamlessly through a continuous range of gear ratios this contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. This is usually done via two different pulleys.
Peer into a planetary automatic transmission and you ll see a complex world of gears brakes clutches and governing devices. A conventional automatic transmission. The flexibility of a cvt with suitable control may allow the engine to operate at a constant rpm while the vehicle moves at varying speeds.
Conversely those on the driven pulley move away from each other. When you start accelerating the cones in the driving pulley come closer. With your run of the mill automatic transmission gears change constantly as you accelerate and decelerate.
The difference between automatic and cvt. Rather the cvt allows the vehicle s engine to run at its most efficient revolutions per minute rpm for a range of vehicle speeds. How does a cvt work.
The lineartronic cvt is an enhanced second generation unit that unlike a traditional automatic transmission delivers an infinite and seamless variability in available drive ratios without any noticeable shifting. To allow the engine to stay at the same rpm while the car accelerates the gearbox has to change the gears inside. All of this happens constantly that s why it is called a continuously variable transmission.
Instead of fixed gears it uses a pair of variable width pulleys that are connected by a flexible belt. When you reach the highest speed or just cruise on the highway the roles of the pulleys are reversed. One of these is driven by the engine while the other will drive the output shafts.
It helps provide maximum engine performance and fuel efficiency and with optional six speed manual mode with steering wheel paddleshifters on premium sport and limited models the lineartronic cvt also maintains a level of sportiness. A cvt is a type of automatic transmission that delivers seamless acceleration without interruption for gear shifts. It doesn t have gears.
By comparison a continuously variable transmission is a study in simplicity. A high power metal or rubber belt a variable input driving pulley an output driven pulley.
