What does the rear axle ratio of a car mean?
1 Answers
The rear axle ratio of a car is an important parameter of the engine, academically known as the final drive ratio. Here are the specific details: 1. The rear axle ratio is the gear transmission ratio of the main reducer in the car's drive axle: The rear axle ratio reduces the speed on the drive shaft, playing a role in deceleration and torque increase. 2. The car's rear axle needs to be used in conjunction with the transmission: Different gears of the transmission have different ratios, and the total gear ratio of the car is the result of multiplying the gear ratio of the transmission's engaged gear by the rear axle ratio. 3. All car rear axles are equipped with a reducer to reduce the speed on the drive shaft, and the ratio is the transmission ratio: The optimal transmission ratio helps the engine to operate under the best conditions and also minimizes gear wear.
