What is the Rear Axle Ratio?

[DiRuth]

Rear axle ratio is an important parameter of the engine, commonly known as the rear axle ratio, with its academic name being the final drive ratio. Below are specific details about the rear axle ratio: 1. Key Factors: The rear axle ratio is related to gears. The power output from the engine and transmission acts on the drive shaft, which rotates to transfer power to the pinion gear of the final drive, driving the ring gear of the final drive to rotate, and subsequently turning the axle shafts. 2. Calculation Formula: Number of teeth on the ring gear ÷ Number of teeth on the pinion gear. In simple terms, when the drive shaft rotates N times to make the axle shaft rotate once, this N represents the rear axle ratio.
