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.

Can I Still Drive When the Vehicle Reminds Me to Change the Engine Oil?

Vehicle reminds to change the engine oil can still drive, but it is best to change it. Definition: Engine oil, also known as engine lubricant, English name: Engine-oil. Density is approximately 0.91×10 cubic (kg/m cubic), hailed as the "blood" of the car. Engine oil consists of two parts: base oil and additives. The base oil is the main component of the lubricant, determining the basic properties of the lubricant, while the additives can compensate for and improve the shortcomings of the base oil's performance, endowing it with certain new properties, making it an important component of the lubricant. Function: It can lubricate and reduce wear on the generator, assist in cooling and temperature reduction, seal and prevent leakage, prevent rust and corrosion, and provide shock absorption and buffering.

Is it necessary to break in a new car by driving at high speeds?

Breaking in a new car by driving at high speeds is beneficial for the engine's performance. More details about the break-in period of a car are as follows: 1. Meaning of the break-in period: The break-in period of a new car is essentially conditioning the car's engine performance and allowing the driver to adapt to the vehicle. It's also a period of adjustment between the driver and the car. Therefore, during this period, it's advisable not to drive at excessively high speeds to avoid potential hazards. 2. Duration of the break-in period: Typically, the break-in period for a car ranges from 1,000 to 1,500 kilometers. However, different manufacturers may have specific guidelines for different models. The break-in period for the car's wheels and brake pads is approximately 200 to 300 kilometers. During this time, it's recommended to drive on roads with good surface conditions and to practice early and gentle braking.

Can I still pay for the motorcycle compulsory insurance after it expires?

You can renew the compulsory insurance after it expires, but if the compulsory insurance has expired and there is no new insurance within the validity period, the vehicle cannot be driven on the road.
