What are the functions of a mechanical transmission system in automobiles?

The functions of a mechanical transmission system in automobiles include: power transmission, changing the transmission ratio, and deceleration. The specific introductions are as follows: Clutch: It can cut off or engage the engine power transmission, serving the following three purposes: ensuring smooth vehicle starting; ensuring smooth operation during gear shifting; preventing transmission system overload. Transmission: Changing the transmission ratio to expand the range of torque and speed variation of the driving wheels, adapting to frequently changing driving conditions, and enabling the engine to operate under favorable conditions (higher power and lower fuel consumption rate). Under the premise that the engine rotation direction remains unchanged, it allows the vehicle to reverse. Reducer: Reducing speed and increasing torque; changing the direction of power transmission (power is transmitted longitudinally and then transferred laterally to the driving wheels through the main reducer).
As a veteran driver with over 20 years of experience, I often marvel at how amazing a car's drivetrain system is. Simply put, it safely transfers the engine's power to the wheels, making the vehicle move. Power transmission is the crucial component—without it, a car would just be a pile of scrap metal, no matter how powerful the engine is. The transmission allows you to adjust speed gears: for example, shifting to a lower gear in traffic jams to avoid stalling, or switching to a higher gear on highways for better fuel efficiency during acceleration. The differential ensures that the left and right wheels rotate at different speeds when turning, providing stability and preventing skidding, which is especially important on wet roads during rainy days. The clutch serves to connect and disconnect—when starting, pressing it down and releasing it slowly prevents the car from lurching forward and crashing into a wall. This system is like the body's network of tendons and veins. Regular maintenance, such as checking the wear condition of the clutch friction plates, can extend its lifespan. Don’t overlook these details—daily driving safety and smoothness depend entirely on it.
As a young commuter who drives my own car every day, I truly appreciate how the drivetrain makes my life so much easier. It efficiently transfers the engine's power to the wheels, allowing me to accelerate swiftly with just a press of the pedal—no strenuous pedaling like on a bicycle. The transmission is incredibly practical: it automatically or manually shifts gears to reduce speed in congested urban areas, preventing engine strain, while higher RPMs on highways save fuel costs. The differential's clever design handles the rotational speed difference between inner and outer wheels during turns, enabling smooth cornering without rollover risks. By controlling the clutch and gear ratios, the system ensures jerk-free starts. For maintenance, I'm meticulous about transmission fluid changes to prevent overheating or leaks, as proper upkeep in city traffic prevents breakdowns that could disrupt my work.
When repairing cars, various faults are common. The mechanical transmission system has a few core functions: first, it transmits the engine's power to the drive axle, ensuring the car can move; second, it adjusts speed and torque through the transmission to match different driving needs, such as climbing hills or rapid acceleration; third, the differential allows wheels to rotate at different speeds during turns to maintain directional stability. Additionally, it controls the power switch to prevent loss of control. I've personally replaced many components, such as worn clutches that can cause gear shifting issues. Regularly checking the quality of lubricating oil is crucial to avoid the entire system failing.
