What is the Principle of Gear Shifting in Cars?

[StStella]

The principle of gear shifting in cars is achieved by changing the transmission gears. The tire drive shaft has gears for different gear positions. When the engine speed remains constant, engaging gears of different sizes with the engine results in the larger gear obtaining a lower circumferential speed compared to the smaller gear. Precautions for car gear shifting include: 1. Mastering the appropriate timing for shifting, i.e., not shifting up too early; 2. Coordinating the clutch pedal, accelerator pedal, and gear lever properly; 3. Releasing the clutch pedal smoothly and promptly after shifting into a new gear; 4. Performing the action quickly to minimize shifting time, reduce kinetic energy loss, and lower fuel consumption.
