A transmission system is a power transmission device that changes the engine's power to the appropriate torque and rotational speed and transmits it to the wheels.
Also simply called a transmission, it is located between the output shaft of the engine and the shaft that rotates the tires.
Various types of transmission systems have been developed as the performance of automobiles has improved. Typical examples include manual transmissions, in which the driver manually shifts gears, automatic transmissions, in which the machine automatically shifts gears, and continuously variable transmissions, which can shift gears steplessly without using shifting gears.
The primary use of a transmission systems is to adjust the driving force by changing gears and increasing or decreasing torque and rpm according to the driving conditions of the vehicle.
For example, when driving on level ground, the car is put into high-speed gear to drive faster. On uphills, you can shift to a lower gear and lower the number of revolutions, so you can drive powerfully reduce the load on the engine, and improve fuel efficiency.
If the power source is an electric motor instead of gasoline or diesel, it can deliver power almost consistently from very low to high RPMs.
Transmission systems are connected to the engine by different-sized types of gears and shafts, and they switch between parts depending on the driving conditions to make the car run efficiently.
Transmission systems are classified by functionality into manual transmission, automatic transmission, and continuously variable transmission.
This is a type of vehicle in which the driver himself manually changes gears. There are gears such as neutral (N), reverse (R), and gears 1 through 6. Manual transmissions are mainly used in sports cars, work vehicles, and commercial trucks.
This type of vehicle automatically changes gears. Currently, this is the most widespread type of vehicle.
This type of car uses a special metal belt regardless of the gear combination and can change gears without using precisely classified gears.
