What Components Make Up a Car's Transmission System?

A car's transmission system consists of the clutch, gearbox, universal transmission device, main reducer, differential, and half-shaft. The function of the car's transmission system is to transmit the power generated by the engine to the driving wheels of the car, generating driving force to enable the car to travel at a certain speed. The power transmission device between the car's engine and the driving wheels is called the car's transmission system, which should ensure that the car has the necessary traction and speed under various driving conditions, as well as guarantee the coordinated variation between traction and speed, enabling the car to have good power performance and fuel economy. It should also ensure that the car can reverse, and that the left and right driving wheels can adapt to differential requirements, allowing the power transmission to smoothly engage or completely and quickly disengage as needed.
The car's drivetrain is the system that transfers the engine's power to the wheels. It mainly consists of several core components: First, the transmission, whether manual or automatic, helps you adjust gears so the car can go fast or slow; then the clutch, used only in manual transmission cars, allows you to disconnect the power when shifting gears; the driveshaft is like a big rod, found only in rear-wheel or four-wheel drive vehicles, connecting the transmission to the rear axle; the rear axle contains the differential, which allows the left and right wheels to rotate at different speeds during turns to prevent skidding; finally, the drive axles directly transmit force to the wheels. I'd also like to add that different car models have different structures: front-wheel drive cars usually combine the transmission and differential into one unit, placed at the front, saving space and being lightweight; rear-wheel drive cars have a more complex structure, with a longer driveshaft but better turning performance; four-wheel drive vehicles add a transfer case to distribute power to the front and rear wheels. When driving normally, it's important to regularly check transmission fluid and component wear, otherwise you might experience rough shifting, strange noises, or a sharp increase in fuel consumption, and repair costs can hit your wallet hard. In short, if the drivetrain is smooth, driving feels as silky as silk; if it's broken, it's as bumpy and uncomfortable as a tractor.
As someone who loves tinkering with cars, I think the drivetrain is the crucial chain that transfers power from the engine to the wheels. Key components include the transmission, which controls gear shifts; manual transmissions have a clutch to disconnect power; rear-wheel-drive cars are equipped with a driveshaft connected to the differential, which manages the speed difference between wheels during turns; finally, the drive axles deliver power. After driving for a while, you'll notice that if the components are in good condition, acceleration is fuel-efficient and smooth. But issues like wear or oil leaks can cause jerking or slipping. I often remind friends to change transmission fluid and check connections during maintenance, and not to ignore drivetrain noises. One more thing: most cars nowadays use automatic transmissions for convenience, with torque converters replacing clutches, resulting in lower overall maintenance costs, but manual transmissions offer more driving fun. Avoid modifying the system recklessly to prevent unbalanced power output and potential damage to the car.
When I first bought my new car, I figured this out: The automotive drivetrain consists of several parts connected in series to transmit power. The basics include the transmission (for shifting gears), clutch (specific to manual transmissions), driveshaft (used in rear-wheel drive), differential, and drive axles. Simply put, the engine generates power, and the transmission adjusts and delivers that power to the wheels. During regular driving, it's important to pay attention to fluid changes to prevent malfunctions; if issues like slipping occur, check for component wear.
