What does the drivetrain include?

The drivetrain generally consists of components such as the clutch, transmission, universal joint drive, main reducer, differential, and half-shaft. Here are some functions of the drivetrain: 1. Achieve speed reduction and torque increase: The engine has high speed but relatively low torque (traction force). The car's drive wheels cannot be directly connected to the engine; instead, the drivetrain reduces speed and increases torque. 2. Enable differential rotation of the drive wheels: When the car turns, the distances traveled by the two wheels are unequal. The outer wheel should rotate faster than the inner wheel, which is achieved by the differential.
I've been driving for over twenty years, and the drivetrain is the system that transmits the engine's power to the wheels. Its main components include the clutch—the pedal you press when shifting gears; the transmission, which houses several sets of gears responsible for changing the vehicle's speed; the driveshaft, a long steel rod that transfers power to the front and rear wheels; the differential, which allows the left and right wheels to rotate at different speeds during turns to prevent skidding; and the axle shafts, which directly connect to the wheels. I used to drive an old manual car, and once when the clutch was worn out, the car would shudder when shifting gears, nearly causing an issue. Nowadays, many automatic transmissions eliminate the clutch pedal, but it's still essential to regularly check the transmission fluid and wear at the connection points. Otherwise, gear shifts may become jerky, affecting driving smoothness. With a well-maintained drivetrain, long-distance driving becomes worry-free.
