A » To calculate the gear ratio of a final drive, divide the number of teeth on the ring gear by the number of teeth on the pinion gear. This ratio indicates how many turns of the pinion are needed to turn the ring gear once, affecting the vehicle's acceleration and top speed. Understanding this ratio is crucial for optimizing performance and efficiency in automotive applications.

A »To calculate the gear ratio of a final drive, simply divide the number of teeth on the ring gear by the number of teeth on the pinion gear. For instance, if the ring gear has 40 teeth and the pinion has 10, the gear ratio is 4:1. This means the pinion turns four times for every one rotation of the ring gear, affecting torque and speed.
