What is the principle of an engine transmission?
2 Answers
The principle of an engine transmission is: each gear has a different transmission ratio, which is equivalent to the meshing of a small gear and a large gear to produce different speeds. When driving at low speeds, a low transmission ratio (3rd gear and below) is used, where the axle speed is lower than the engine speed. According to the formula P=FV, driving force is obtained. At high speeds, a high transmission ratio (4th gear and above) is used, where the axle speed is higher than the engine speed, reducing traction to achieve higher speeds. The transmission consists of a gear transmission mechanism and a control mechanism, and a power output device can be added when necessary. There are two classification methods: by the way the transmission ratio changes and by the control method.
The principle of a transmission is actually quite simple: it transfers the engine's power to the wheels through different gear combinations. Imagine when starting or climbing a hill, more power is needed. The transmission uses lower gears to allow the engine to rotate slowly but output high torque, making it easy to pull the car. During high-speed cruising, higher gears enable the engine to rotate quickly but with less output force, ensuring both fuel efficiency and smoothness. Manual transmissions rely on the driver to press the clutch and shift gears to control gear changes, while automatic transmissions use a hydraulic system and computer to automatically determine shift points. When driving a manual car, I often feel that shifting requires anticipation and coordination with the throttle, whereas automatic cars are more convenient but lack some fun. For maintenance, it's crucial to regularly change the transmission fluid to prevent sediment buildup and avoid gear wear. Don't overlook this, as it can lead to gear jamming, strange noises, or major malfunctions.
