The Parts of a Manual Transmission
While significantly less complicated than automatic transmissions, manual transmissions are also composed of numerous parts that must work together seamlessly for the vehicle to effectively shift gears. Understanding the different parts of a manual transmission can help drivers better care for and maintain their vehicles. To get to know your manual vehicle better, consult this guide to some of the main parts of a manual transmission.
In a manual transmission, synchronizers facilitate smooth gearshifts by adjusting the speed of the input shaft and the selected gear so that they can operate at a synchronized speed. If there is a difference in the speeds between the input shaft and gear, the gears can grind or clash during engagement. Synchronizers prevent such grinding from occurring by creating friction, which helps equalize the speeds of the input shaft and gear without having to manually balance the engine revs for each gearshift.
A clutch is perhaps the most well-known part of a manual transmission. It is responsible for engaging and disengaging the engine with the transmission. To disengage the engine, the clutch is pushed down. Doing so allows the transmission to shift into a higher or lower gear as necessary. Without this essential manual transmission component, changing gears would be exceedingly difficult and the engine would stall each time the vehicle stopped moving.
Another important component of a manual transmission is the selector fork. The selector fork looks like a mechanical arm and is responsible for sliding the collars along the output shaft into position. In doing so, the selector fork helps put the transmission into higher or lower gears.
Gears are obvious components of a manual transmission system. They are primarily responsible for generating torque, which impacts the speed the vehicle can travel. Larger gears generally generate a greater amount of torque, which helps slow down the vehicle. Smaller gears, on the other hand, generate less torque and allow the vehicle to run at a faster speed.
