Manual Transmissions-How Do They Work?
If you have ever owned or driven a stick-drive, there is no way that you haven’t ever messed up the timing of your clutch plate. Driving stick is a tad bit more complicated than an automatic. You have to press the clutch before putting your automobile in gear. Otherwise, you get to witness a weird grinding sound none of us want to hear.
Why does that happen?
In this post, we will let you in on the way a manual/stick transmission works so that the next time you drive one, you know exactly what is going on under the hood.
The Components
There are two major components in a stick drive: the clutch and the gear. While the clutch is further divided into several key components, the gear divides the amount of torque based on the gear you are in.
The Process
There are several steps involved in making the all-traditional stick drive to work. In a stationary state, the clutch pedal remains depressed. When you press the clutch in order to put the car in gear, the clutch disc, which normally sits between the flywheel and the pressure plate, gets released from its position. This disrupts the direct link between the transmission and the engine. This allows your engine to run while keeping the state of your car stationary.
As you press the clutch and put the car into first gear, the selector fork inside is forced to mesh the collar—sitting right in the middle of the first two gears—towards the first gear. In other words, a low amount of torque is now available for the car to get out of the stationary position. As you gently leave the clutch while pressing the throttle, the gear sets in place and the transmission and engine get connected.
As you change the gears, the gear selector engages the collar into the selected gear. The collar has teeth that allow it to fit into the holes of each gear holding on to it. That weird grinding sound we talked about earlier, it is when the dog teeth—teeth of the collar—go through a failed attempt of clipping the teeth into the designated holes.
The RPM
For every gear, there is a perfect range of speeds you can cater to. This is why if you run directly from gear one to fifth, the car will take ages to match the rpm—the speed at which the car should be while switched into a certain gear. And this is why, when you downgrade from gear four to three while maintaining a speed that matched an rpm of gear four, the dog teeth do fail to clip onto the reduced gear. The result is that weird grinding sound you hear.
