How to Choose the Rear Axle Ratio?

[Galadriel]

Methods for selecting the rear axle ratio: 1. For the same gear, a smaller ratio means faster speed. A smaller rear axle ratio results in weaker climbing power, while a larger rear axle ratio provides stronger climbing power. 2. The rear axle ratio generally refers to the gear ratio of the ring and pinion gears in the differential. A larger ratio means the driven gear has relatively more teeth, resulting in slower rotation per revolution and slower wheel speed. The rear axle ratio is an important parameter of the engine, commonly known as the rear axle ratio, and academically referred to as the final drive ratio. The rear axle ratio serves to reduce speed and increase torque. Therefore, a high-horsepower engine with sufficient power reserves and inherently strong torque and explosive force can rely less on the torque-increasing effect of a large rear axle ratio. The transmission can also serve a similar purpose.
