Automatic transmission (automatic transmission)
* Operating principle: Using planetary gears with a set of clutches and brake bands.
* Gear shifting: Electronic or hydraulic control, occurs automatically depending on engine speed.
* Number of gears: Typically from 4 to 10.
* Peculiarities:
* Smooth gear shifting, without jolts.
* Higher reliability and durability than CVT.
*Higher repair costs.
* Availability of parking mode.
CVT (CVT)
* Operating principle: Using two variable diameter pulleys and a metal belt.
* Gear shift: Constant, smooth change in gear ratio.
* Number of gears: Infinite number.
* Peculiarities:
* Maximum smooth gear shifting.
* Fuel efficiency.
* Lower reliability and durability than automatic transmission.
* Lower repair costs.
* Lack of parking mode (replaced by electronic parking brake).
Comparison
| Characteristics | Automatic | CVT |
|—|—|—|
| Working principle | Planetary gears | Variable Diameter Pulleys |
| Shifting gears | Automatic, fixed | Smooth, endless |
| Number of gears | From 4 to 10 | Infinite |
| Smooth shifting | Smooth, but with shocks | Maximum smoothness |
| Fuel efficiency | Average | High |
| Reliability | Higher | Lower |
| Repair cost | Higher | Lower |
| Parking mode | Yes | No |
Conclusion:
The automatic transmission is more reliable and durable and has a traditional gear shift scheme with a fixed number of steps. The CVT provides maximum smoothness and fuel efficiency, but is inferior to automatic transmission in terms of reliability. The choice between automatic transmission and CVT depends on individual preferences and priorities.
