The internal structure of the 6-speed Manual Gearbox.

The internal structure of the six-speed Manual Gearbox, which has the principle of transmitting power from the engine to the wheels through different gear ratios, is as follows:

1. Power gain (Input)

Power from the engine is transmitted through the clutch to the Input Shaft. On this shaft are gears of various sizes installed, which always rotate with the engine when we release the clutch.

2. The Shifting Process

When the driver wants to change gears, the mechanism works together as follows:

• Gear Shift Lever & Selector Rod: When you move the gear head (Gear Shift Knob), the force is passed through the gear lever to the gear selection axis (Selector Rod).

• Shift Forks: The selection axis will kick the gear pincer (Shift Forks) to move left or right according to the selected gear position.

• Synchronizer Hub & Rings: The pincer pushes the Synchronizer Hub kit (Synchronizer Hub) to move to lock with the desired gear gear. The Synchronizer Rings (Brass Ring) equalizes the speed of the gear gear and shaft before grinding together, so that the gear changes are soft and noisy.

3. Output (Outputted)

• When a synchronizer lock assembly is attached to one of the gear gears (such as 1st or 2nd gear), it is about to be relayed from the Input Shaft through that pair of gears to the Output Shaft (output shaft).

• The Output Shaft rotates at speeds and torques that are modified to the ratio of the respective gear gear to continue transmitting power to the center axle and car wheels.

• Bearings (bearings): Helps reduce friction and support the rotation of the shaft to be fluid.

• Gearbox Housing: A gear shell that serves to encapsulate all parts and contain gear oil for lubrication.

• Gears (1, 2, 3, 4, 5, 6, R): Each gear set will have a different size, to produce "torque" in the low gear, and "speed" in the high gear.

In a nutshell: This system changes the movement from rocking your gear to moving your pincers to locking different sizes of gear to choose the right torque and speed to drive.
