What is the Difference Between 4.33 and 4.875 Gear Ratios?

[LaOmar]

4.33 and 4.875 gear ratio differences: 1. Different number of gear teeth: The 4.33 driven gear has 32 teeth, and the driving gear has 7 teeth; the 4.875 driven gear has 39 teeth, and the driving gear has 8 teeth. 2. Different driven gear rotation speeds: For the 4.33 ratio, when the rear tire of the same specification completes one full rotation, the driven gear rotates 4.33 times; for the 4.875 ratio, when the rear tire of the same specification completes one full rotation, the driven gear rotates 4.875 times. The transmission ratio of the automobile transmission system includes the gear ratio of the main reducer and the gear ratio of the gearbox. The advantages of an equal ratio distribution of gear ratios are: 1. The engine operating range is the same, making it easier to control during acceleration; 2. The engine power corresponding to each gear is relatively high, which is beneficial to the vehicle's dynamic performance.
