Which Gear is Larger in a Comparison of First to Fifth Gears?
2 Answers
In the comparison of gears from first to fifth, they differ in size, with the first gear being larger. The relevant details are as follows: Smaller gears correspond to higher gears: The transmission achieves speed and torque variation through different gear combinations. The higher the gear of the car, the smaller the gear on the intermediate shaft of the transmission will mesh with an even smaller output shaft gear, thus increasing the output shaft's rotation speed, which manifests as higher car speed. In other words, the lower the car's gear, the larger the gear; the higher the gear, the smaller the gear. The function of the gear transmission: The gear transmission mainly consists of two parts: the gear shifting mechanism and the gear shifting actuator. The gear shifting actuator can place the planetary gear set in different meshing states to achieve different transmission ratios.
When it comes to gear sizes from first to fifth gear, the first gear is definitely larger because it's responsible for high torque output when the car starts, much like a strongman pulling a cart, helping you accelerate from a standstill. In contrast, the fifth gear is much smaller, focusing on low resistance and efficiency for high-speed cruising. The reason lies in the gear ratio design: the first gear has a high gear ratio, amplifying the engine's force to the wheels for a more stable start; the fifth gear has a low gear ratio, allowing the car to move faster with fewer engine revolutions, saving fuel and running quietly. Driving a manual transmission car, the first gear feels powerful but slow, while the fifth gear provides smooth acceleration. In daily driving, shifting gears at the right time is crucial—for example, avoid using fifth gear on slopes to prevent excessive gear wear. During transmission maintenance, regular oil changes can prevent issues and ensure smooth operation of each gear. In short, the difference in gear sizes is designed to meet varying speed needs, a clever design that becomes more intuitive with driving experience.
