What is the gear ratio comparison from first to fifth gear?
2 Answers
Gear ratio comparison from first to fifth gear shows that they differ in size, with the first gear being larger. Relevant details are as follows: Lower gears have larger gears: The transmission achieves speed and torque variation through different gear combinations. The higher the gear, the smaller the gear on the intermediate shaft of the transmission meshes with an even smaller output shaft gear, resulting in increased output shaft speed, which translates to higher vehicle speed. In other words, the lower the gear, the larger the gear; the higher the gear, the smaller the gear. Function of gear transmission: The gear transmission mainly consists of a gear shifting mechanism and shift actuating components. The shift actuating components enable the planetary gear set to be in different meshing states to achieve different transmission ratios.
As a young owner who often drives manual transmission cars, I find the gear ratio changes from first to fifth gear incredibly fascinating, like transitioning from a thick rope to a thin one: first gear has the highest ratio, typically around 3.0 to 4.0, where the engine revs high but the speed is low, perfect for starting or climbing hills; second gear drops to around 2.0, making acceleration smoother; third gear settles near 1.5, ideal for stable city driving; fourth gear reduces to 1.0, almost reaching direct drive; and fifth gear is the lowest, approximately 0.8 to 0.9, where the engine runs at lower RPMs during highway cruising, maximizing fuel efficiency. When shifting gears, I can distinctly feel the torque gradually diminishing while the car accelerates faster, and developing a habit of upshifting early helps avoid jerky movements. This contrast not only enhances driving pleasure but also protects the engine by maintaining lower RPMs, extending its lifespan.
