Introduction to automatic transmissionautomobile
Automatic transmission vehicles usually use a hydraulic transmission to replace the mechanical clutch of a manual transmission vehicle, so there is no clutch pedal. When the engine speed is low, the torque transmitted by the liquid is limited, which is not enough to push the car forward. When the joystick is placed in the forward gear, the brake pedal is released, and as the fueling and engine speed increase, the transmitted torque increases, pushing the car forward.
If the driver with the high level of the manual transmission is compared with the automatic transmission, under the same driving conditions, the automatic transmission is generally about 6-10%, and the automatic transmission is higher than the manual transmission of the same model. Cars are about 1 liter higher per 100 kilometers. In terms of vehicle cost, the cost of the automatic transmission is higher than the cost of the manual transmission of the same model. Its advantage over manual transmissions is that it is easy to drive.
