Understanding and important components of a manual transmission

Understanding and important components of a manual transmission – Cars of any type and brand have a system in the engine which is commonly known as a transmission. Transmission in the car is divided into two types, namely automatic transmission, and manual transmission. Although many people have switched to automatic transmission cars, some people are still interested in manual transmission cars.

Understanding and important components of a manual transmission

This is because manual transmission still has advantages that are not obtained in automatic transmission. One of the advantages is being able to adjust the speed according to the rider’s wishes. Cars with manual transmissions are also more powerful than automatic transmissions. Therefore, some people still maintain their vehicles with this transmission.

Although many have abandoned manual transmissions, some communities claim that manual transmissions are the best for car drivers.

Definition of Manual Transmission

Before that, you must understand the basics of this manual transmission. This is for you if you experience problems with the car’s transmission so that you can overcome them. Manual transmission is a component in the engine and serves to change the speed and power of the engine to the wheels that can move.

This power transfer system has several components, namely differential clutch, transmission, wheels, and vehicle axle. Some of these components are interrelated and connected as the driving force of the car. For manual transmissions, the position and components are located at the front end after the clutch.

With this transmission, the power generated comes from the engine which is then forwarded to the propeller shaft so that the car can run. So, the meaning of manual transmission is in short, namely the components of the transfer of power generated in the engine to the wheel axle that moves or runs at a specified speed.

Manual Transmission Components in Cars

1. Transmission Input Shaft

important components of a manual transmission
Input Shaft manual transmission serves to continue the engine rotation directly to the transmission gears. Usually, it will be connected directly to the clutch plate and flywheel bearing. (Input Shaft AX15 Transmission Wrangler + Cherokee 97-99.)

Basically, this component is a shaft or gear that works together with the clutch. Its function is to rotate the teeth on the gearbox.

2. Gear Transmission

This component functions as a converter of the input power generated by the engine into the output torque force. This change will of course be adjusted to what is needed by the vehicle.

The transmission gear is separated from one gear to another. But they are all connected through a shaft which also has several other components in it. The number of transmission gears according to the manufacturer of each car. For now, there are at least 4 plus one reverse gear. And for some vehicles, there are up to 8 gears plus reverse gear.

3. Gear Adjustment (Synchcroniser)

The role of this component is seen when the driver can still shift gears safely and comfortably even though your car is running.

In every synchronizer assembly, there are three primary components:

  • Slider, also referred to as a shift sleeve
  • Keys, balls, or struts, depending on the specific design of the synchronizer
  • Blocking rings also referred to as balk rings

4. Shift Fork

The shift fork transfers the shifting motion from the shifting actuation to the sliding couplings.

Furthermore, the shifting fork functions to move the teeth on their axis so that the teeth will be easier to install or even move.

5. Linkage (Shift Linkage)

These drawings should help when you have to remove or adjust your shift linkages (220D, 240D, 190D, and 190E). They will certainly help to get the rods back in the proper locations. If you have shifting problems then check the adjustments. Note the use of a locking pin in the base of the shifter assembly. You can fabricate anything that fits in the hole and keep the levers aligned.

The function of this component is as a liaison between the gear lever and the shift fork or what is often called the shift fork.

6. Gear Shift Lever

This component functions as a driver controller so that they can shift the transmission gear according to the driving conditions they want. This component is usually located close to the driver.

7. Body Transmission (Transmission Case)

The transmission body is used as a transmission bearing holder along with the axles. In addition, it can also be used as a container to store car transmission oil. Thus, the movement or shift of each component in the car’s transmission system can remain smooth and smooth.

8. Output Shaft

The output shaft is a shaft that has a function to transfer torque from the transmission system to the last gear. In addition, these components can also be used as a gear holder in a car.

9. Bearings (Main Bearings)

Next, this component serves to reduce the friction that occurs between the surfaces of rotating components in the transmission system.

10. Counter Gear

The counter gear is used to generate torque from the input gear to the speed gear.

11. Reverse Gear

This component is useful for changing the direction of rotation of the output shaft. This is what makes our car can run backward when you move the gear lever towards reverse gear.

12. Slave Hub

The slave hub functions as a lock for accelerating gear adjustment. With this component, the output shaft can rotate and stop.

​13. Speedometer Gear

With the speedometer gear, the speed of the car you are driving can be measured.

Thus an explanation of the manual transmission in cars and some of the related components, hopefully, this article is useful for you.
