Additional gears in automatic transmissions
Automatic transmissions (automatic transmissions) with additional gears include the following types:
CVT (CVT)
*Continuously variable transmission that provides smooth and efficient gear changes.
* There are no fixed gears, instead the belt or chain moves along cones of variable diameter.
* Allows the engine to operate at optimal speed for fuel economy and performance.
Dual Clutch (DCT)
*Contains two clutch packs for even and odd gears.
* Provides fast and smooth gear shifting comparable to a manual transmission.
* Improves acceleration and fuel economy.
Multi-stage automatic transmission with planetary gears
* Has several fixed gears that are shifted using planetary mechanisms.
* Typically has 6 to 10 gears, providing smoother shifting and improved fuel economy.
Robotic Manual Transmission (RMT)
*Combines an automated gear shift mechanism with a traditional manual transmission.
*Uses actuators to automatically change gears, eliminating the need to use the clutch pedal.
* Provides better acceleration and fuel economy compared to traditional automatic transmissions.
Benefits of additional gears
*Smooth Shifting: Smoother gear shifts thanks to more gear shifts.
* Improved Fuel Economy: Optimal gearing for reduced fuel consumption.
* Increased Performance: Additional gears provide better power transfer to the wheels.
* Reduced noise and vibration: Smoother gear shifting reduces noise and vibration.
* Improved Towing: Additional gears provide more power and torque for towing.
Disadvantages of additional gears
*Higher Cost: Automatic transmissions with extra gears tend to be more expensive than traditional automatic transmissions.
* More complex maintenance: Additional gears may require more specialized maintenance and repair.
* Potential Reliability Issues: Some types of automatic transmissions with extra gears may be more susceptible to reliability problems than traditional automatic transmissions.
