What Are the Common Types of Geartronic Transmission?
What is geartronic transmission

Before understanding the structure of the geartronic transmission, we must first know why the gearbox is needed and what it does. According to different driving conditions, the speed and power requirements of the vehicle can be changed within a large range. To achieve this, in addition to effective braking, the choice of gear is also very important. Therefore, changing the transmission ratio to adapt to different driving conditions is a major role of the gearbox. In addition, the realization of reversing and the use of neutral to cut off the power transmission without turning off the engine are also the reasons why geartronic transmission is widely used in the field of internal combustion engines.

1. Manual gearbox

Manual transmissions aren't a hallmark of lower-spec models. This position needs to be stated before the introduction of this type of volvo geartronic transmission. Vehicles equipped with manual transmissions require the driver to switch gears with their hands and feet during driving. But some people also see this direct communication with machinery as a joy.

The manual transmission also has gears. We commonly have a 5-speed manual geartronic transmission and a 6-speed manual transmission. What is certain is that the more gears, the tighter the gear ratio can be, the more comfortable the power connection will be, and the better the performance of fuel economy and comfort at high speed.

2. Automated mechanical transmission (AMT)

From the point of view of operation mode, models equipped with AMT geartronic transmission can be attributed to the category of automatic transmission models. But structurally speaking, the AMT gearbox adopts the structure of the manual geartronic transmission more. However, it controls the clutch through a set of servos, freeing the driver's left foot. The mechanism installed above the geartronic transmission is the control module of the AMT gearbox. Under the deployment of the transmission control unit, the control module can control the clutch and at the same time select the gear required for driving. During the entire driving process, the driver controls the vehicle speed only through the accelerator and brake pedals. Of course, you still have to flip the shift lever to select neutral, forward or reverse.

3. Hydraulic automatic transmission (AT)

At present, the vast majority of automatic geartronic gearbox transmission models on the market are equipped with this type of automatic transmission, and the number of gears is still one of the standards to measure the technical content. The original 4-speed automatic transmission is no longer mainstream. At present, most family cars have 5 or 6 gears, while luxury cars favor automatic transmissions with more gears.
