How Transmission Gear works

Transmission gears are an essential part of the drivetrain in vehicles, and they enable the engine power to be transmitted to the wheels with the appropriate amount of torque and speed. The transmission system consists of a gearbox, clutch, and differential.

The gearbox is responsible for providing multiple gear ratios to the engine output shaft, which is then transmitted to the wheels through the driveshaft and the differential. The gear ratios are achieved by engaging different sets of gears of different sizes that mesh with each other, thus changing the speed and torque of the rotating shaft.

In a manual transmission system, the driver manually selects the gear ratio by operating the gear shifter and clutch pedal. When the clutch is engaged, the engine power is transmitted to the gearbox through the input shaft. The gears on the input shaft mesh with the corresponding gears on the output shaft, and the power is transmitted to the wheels.

In an automatic transmission system, the gears are changed automatically by a hydraulic or electronic system based on the engine speed and vehicle speed. The torque converter replaces the clutch, and it allows the engine to continue running while the vehicle is stationary. The transmission system automatically selects the gear ratio depending on the speed and load conditions.

In summary, transmission gears work by changing the gear ratio between the engine and the wheels, which affects the speed and torque of the vehicle. Manual transmissions rely on the driver to select the gear ratio, while automatic transmissions use a hydraulic or electronic system to automatically select the gear ratio based on the vehicle speed and load conditions.
