What are the differences between the gears in a manual transmission car?
1 Answers
In a manual transmission car, the first gear is the starting gear, the second gear is the driving gear, the third gear is the acceleration gear, the fourth gear is the medium-high speed driving gear, the fifth gear is the high-speed gear, and the R gear is the reverse gear. Introduction to the gears in a manual transmission car: First gear: The first gear is the starting gear, used when the car moves from a stop or climbs a steep slope. The speed is generally around 10 km/h. Second gear: The second gear is the driving gear. It is used as a transitional gear after the car starts to accelerate or for low-speed driving. The speed is generally around 20 km/h. Third gear: The third gear is the acceleration gear. Starting from this gear, you can accelerate by pressing the throttle to increase the car's speed to a certain level. This gear is used at speeds between 20-40 km/h and is commonly used for city driving. Fourth gear: The fourth gear is the medium-high speed driving gear. This is generally the highest gear used on urban roads except for elevated roads. Depending on the vehicle's speed, it is typically used at around 60-70 km/h. Fifth gear: The fifth gear is the high-speed gear. It is used only on elevated roads or highways, generally at speeds of 80 km/h or above. R gear: The reverse gear, used when reversing the car. Principle of gear shifting in cars: 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 unchanged, engaging different gears with the engine results in the larger gear obtaining a lower circumferential speed than the smaller gear. In low gears, the gear is larger, and the engine drives a larger radius with a smaller radius, allowing the car to obtain greater driving force. In high gears, the engine drives a smaller radius, resulting in a faster circumferential speed but less driving force.
