What are the components of a drivetrain system?

The drivetrain system mainly consists of components such as the transmission, drive shaft, universal joint, half shaft, final drive, differential, bearings, etc. Below is related information about the drivetrain system: Function of the drivetrain system: To transmit the power generated by the engine to the driving wheels of the vehicle, thereby generating driving force that enables the car to move at a certain speed. Based on the layout, it can be categorized into front-engine rear-wheel drive (FR), rear-engine rear-wheel drive (RR), front-engine front-wheel drive (FF), and all-wheel drive (AWD). Working principle of the drivetrain system: The working principle of the drivetrain system involves concentrating the engine's work on the "crankshaft." The power is then transmitted from the crankshaft through the clutch into the "transmission." After being adjusted by the transmission's "gear ratio," the power is output to the drive shaft, which in turn drives the tires to move.
As for the transmission system, it's essentially the middleman that delivers power in a car. Having driven for over a decade, I know it consists of several major components: The clutch serves as the starting point for manual vehicles, responsible for engaging the engine with the gearbox. Inside the gearbox are gears that constantly adjust the engine's RPM. The driveshaft, resembling a steel rod, transfers power from the gearbox to the rear. The differential sits between the front and rear axles, distributing force to the left and right wheels. Finally, the drive axles connect to the tires, propelling the vehicle forward. These parts work in unison, and if any fail—like a worn clutch causing gear slippage or low transmission fluid leading to grinding noises—it can result in rough starts or even stalling, which is extremely dangerous. I recommend regularly checking the color and level of transmission fluid and changing it promptly to prevent overheating, ensuring smooth operation. Rear-wheel-drive cars have longer driveshafts, while front-wheel-drive setups are simpler, but core maintenance should never be neglected, as driving safety always comes first.
