What Does Rear Axle Ratio Mean?

[DeIsla]

Truck rear axle ratio refers to the gear transmission ratio of the main reducer in the vehicle's drive axle. It equals the ratio of the rotational angular velocity of the driveshaft to that of the axle's half-shaft, and also equals the ratio of rotational speeds. Below are specific details about vehicle speed ratio: Meaning of Vehicle Speed Ratio: Speed ratio refers to the gear transmission ratio of the main reducer in the vehicle's drive axle, equaling the ratio of the rotational angular velocity of the driveshaft to that of the axle's half-shaft, and also equals the ratio of rotational speeds. Speed Regulation Range: When using a mechanical reducer, the ratio of the motor's rated speed nN (r/min) to the output shaft speed nL of the reducer is called speed ratio 1 (also known as transmission ratio), i=nN/nL. When other speed regulation methods are employed for the motor, such as variable frequency speed regulation or slip speed regulation, the ratio of the motor's maximum speed to its minimum speed is called the speed ratio, indicating the range of speed regulation.
