What Is Transmission System In Vehicles, Types, Applications

Hello guys, welcome back to my blog. In this article, I will discuss what is transmission system in vehicles, what is manual transmission system in an automobile, what is automatic transmission system in an automobile, working of the manual transmission system, working of an automatic transmission system, the difference between the manual transmission system and automatic transmission system, etc. Each and everything I will try to explain in a simple way.

If you have any doubts related to electrical, electronics, and computer science, then ask questions. You can also catch me on Instagram – CS Electrical & Electronics And Chetan Shidling.

Transmission System In Vehicles

Every vehicle requires a transmission system. The function of the transmission system is to provide different ratios of speed and torque. By operating the transmission system, the driver can change the speed and torque of the car. The transmission system is operated manually or by automatic. There are almost many types of transmission systems is available but many cars used nowadays is as manual transmission systems and automatic transmission systems in vehicles.

Purpose of the transmission system

1. It must provide varying gear ratios.
2. It must provide a reverse gear for moving vehicles in the reverse direction.
3. It must provide a neutral or disconnecting arrangement so that the engine can be uncoupled from the wheels of the vehicle.

In this article, I will discuss only the manual and automatic transmission systems.

Manual transmission system

When the driver presses the clutch and changes the gear level depending upon the speed then it is called a manual transmission system. In the manual transmission system, the changing of gear ratios from first gear to last gear is done by the driver.

Automatic transmission system

In the automatic transmission system, the changing of gear level is done automatically without the involvement of the driver. Sensors and ECU’s are used to detect the speed of the car to change the gear.

Working of a manual transmission system in vehicles

The manual transmission system consists of a driver-operated clutch. Gearstick is used for changing the gear level. Based on vehicle speed the driver operates the gearstick.

During the first Gear

Input Shaft (orange) is connected to the Engine. The silver color is countershaft. The output shaft (yellow) is connected to the drive shaft. Gear gets locked to the shaft with the “sleeve”

•S1/S2 = N2/N1

•S is speed and N is the number of teets.

As you guys can observe the above images of different gears. By changing the gearstick, the gear ratios are changed by the driver. The manual transmission system has more noise. Here the driver’s effort is required.

Working of automatic transmission system in vehicles

As we all know that the changing of gear level in the automatic transmission system is done automatically without the involvement of the driver. To change the gears, sensors are used to determine the speed of the vehicle. The automatic transmission system consists of a torque converter that will change the gear ratio.

The automatic transmission system consists of a planetary gear set. The parts of the planetary gear set are; ring gear, sun gear, planet carrier, and planet pinion.

Two or more planetary gear will be connected to the shaft. During first gear, only one sun gear will rotate, during second gear, first planetary sets both sun gear and ring gear will rotate and for third, fourth gear two or three sets will rotate. Well, guys watch a video that is provided so that you can understand the concept clearly.

Difference between manual and automatic transmission systems in vehicles

1. In the manual transmission system, changing of gear level is done manually by driver whereas in the automatic transmission system, changing of gear level is done automatically.
2. In the manual transmission system, the gear system produces more noise whereas, in automatic transmission systems, there is no noise pollution.
3. The gearstick is there in a manual transmission system whereas in an automatic transmission system stick is present to change modes(neutral, reveres, park, etc).
4. The manual transmission system has a gearstick with first gear, second gear, third gear, fourth gear, neutral, and reverse. The automatic transmission system has four modes such as drive, reverse, neutral, and parking mode.
5. The manual transmission system requires more maintenance. The automatic transmission system requires less maintenance.
6. The automatic transmission system-base car is good for a long drive with family and it is also good during traffic. The driver should regularly change gear during traffic in a manual transmission system.
7. The manual transmission system is cheap compared to the automatic transmission system vehicles.
8. The manual transmission system offers more control for drivers whereas the automatic transmission system does not.
9. The manual transmission system consists of a clutch whereas the automatic does not.
10. Due to pressing gears regularly, the legs of the driver get pain in a manual transmission system whereas in automatic, there is no clutch.
