Difference between car at,mt,amt

1.AT: AT (AT: AutomaticTransmission) stands for automatic transmission. Automatic transmission consists of a hydraulic torque converter, planetary gear transmission, control mechanism. According to the road conditions can automatically change speed and torque, the driver can pay full attention to the road traffic and will not be shifted to get busy.

Advantages: easy to operate, comfortable to drive, can reduce driver fatigue.

Disadvantages: Inefficient transmission, a drag on gas mileage.

2. MT: MT (MT: ManualTransmission) stands for Manual Transmission, also known as mechanical transmission, that is, you must use your hand toggle the gearshift lever, through the change of gears to change the gears in the transmission to change the position of the gears, so as to achieve the purpose of changing speed.

Manual transmission is a gearshift device used to change the speed and torque transmitted from the engine to the drive wheels, which enables the car to obtain different traction and speed under various working conditions such as starting in place, climbing, turning, accelerating and so on, and at the same time, enables the engine to work in a more favorable range of working conditions.

Advantages: simple structure, reliable performance, high transmission efficiency, more fun to drive.

Disadvantages: The operation steps are more troublesome, and the stuttering is obvious when switching gears, which makes the driver easily tired in the congested city road or traffic jam.

3. AMT: AMT refers to the mechanical automatic transmission, simply put, it is the automated MT, automatic clutch manual transmission; AMT transmission is still based on the traditional manual transmission, its working principle is in fact very simple, the vehicle in the start and shift, the clutch is controlled by a hydraulic pump to control the separation and engagement, the gear shift is also operated by the hydraulic structure. The driver only needs to push and pull the gear lever to complete the upshift and downshift, and the transmission control computer will switch gears on its own according to the vehicle speed, engine load and other data in automatic mode.

Advantages: simple structure, high efficiency and low cost of transmission.

Disadvantages: When the AMT transmission is traveling on a slope or at a low speed, it is difficult for the clutch to reach a perfect "half-linkage" state, so there is a little bit of frustration.

Expanded information

The main functions of the automobile gearbox are as follows:

1. To change the transmission ratio, expand the range of torque and speed of the driving wheels to adapt to the frequently changing driving conditions, and at the same time, make the engine work in favorable conditions (higher power and lower fuel consumption);

2. To make the car drive backwards when the engine rotation direction is unchanged;

3. To utilize neutral, interrupting power transmission to enable the engine to start, idle, and facilitate transmission shifting or power delivery.
