What is the driving principle of a manual transmission?

[CodyLynn]

Manual transmission operates on the principle of changing the gear ratio through the shift fork, thereby altering the driving torque to suit different working conditions. A manual transmission refers to a vehicle that uses a manually operated mechanical gearbox to adjust speed, where the driver must manually move the gear lever to change the meshing position of gears inside the transmission, thus altering the gear ratio to achieve speed variation. The method of driving a manual transmission is as follows: 1. Press the clutch pedal all the way down; 2. Push the gear lever to engage the first gear, which is the starting gear; 3. Gently press the turn signal lever downward to activate the left turn signal, indicating to vehicles ahead and behind; 4. Press the horn button to alert pedestrians in front of the vehicle of the imminent start; 5. Release the vehicle's handbrake; 6. Lift the left foot upward until the clutch reaches the half-clutch state, at which point the vehicle begins to vibrate slightly; 7. As the vehicle starts to move, release the clutch and gently press the accelerator.
