Discover the different types of automatic transmission to choose the best one.
In the past, anyone who chose a car with an automatic transmission was laughed at for not knowing how to use a manual. Today, however, the automatic driving lessons coventry transmission is conquering more and more motorists thanks to priceless comfort and top-level technology.
Automatic gearbox: how it works
The advantage of the automatic transmission compared to the manual is that you do not have to use the clutch pedal and change gear. The control unit will take care of all this directly and will decide with total autonomy when to change gears depending on the engine speed reached. By doing this the driver will have the opportunity to rest his left foot as there is no clutch pedal.
How to use automatic transmission
Using an automatic transmission is different from a manual one. Here, as mentioned, the clutch pedal will be absent, while the gear lever can be moved to certain positions indicated by letters. Let’s see what they are.
Automatic letter change
Moving the automatic transmission lever will lock the drive shaft. This choice must be made every time the car is stopped.
By positioning the automatic gearbox lever in, i.e. neutral, you will go into neutral, while to reverse gear it will be mandatory to position the lever on the letter “R”.
To proceed with driving, you will have to position the automatic transmission lever on the letter “D” which indicates drive.
The passage of the lever from one letter to another must necessarily take place with the vehicle stationary.
Types of automatic transmission
Thanks to constant research and development and technological evolution, the automotive world has presented different types of automatic transmissions in recent years . Let’s see what they are.
Semi-automatic gearbox
This type of automatic transmission eliminates the clutch pedal, but leaves the driver the choice of changing gear. The semi-automatic is appreciated for its reduced consumption , performance similar to that of a manual and almost imperceptible gear changes in double clutch systems.
Dual clutch automatic transmission
This gearbox is the most advanced and is characterized by the presence of two clutches, as can be guessed from the name. One clutch is dedicated to odd gears and one to even ones, and both are connected to two drive shafts that rotate simultaneously. The double clutch gearbox guarantees absolute gear changes speeds unattainable by a manual system.
Torque converter automatic transmission
In the past this system did not give good publicity to the automatic transmission due to gear changes that were not at all quick and excessively expensive, but today the situation has definitely changed. The operation of these devices is easily explained: the driving torque is transferred via a hydraulic converter positioned between the engine and gearbox and, thanks to valves, a difference in oil pressure is caused which allows the gear change.
Robotic gearbox
The robotized gearbox is that device where the transition from one gear to another occurs in an automatic driving lesson in birmingham. In fact, it is the control unit that operates the clutch and engages the gears after having selected them if necessary. This type of gearbox has two operating modes: the first is totally automatic, and in this case the control unit decides autonomously when to change and which ratio to insert, while the second is manual and allows the driver to choose the moment in which to make the shift to a lower or higher ratio.
Continuously variable gearbox
This type of automatic transmission is characterized by the presence of a pair of pulleys around which a belt is wrapped. Based on the engine rpm the pulleys move and in this way the diameter of the belt varies. The system is adopted by Toyota and allows the engine to always operate at maximum torque speed to the benefit of consumption.
