Axle ratio

Unlike in karts, where wheels connected by an axle must rotate at the same spee most modern vehicles have elaborate gear trains on their rear axle to allow the wheels to rotate at different rates so they can maintain traction while they turn. Axle ratio is the number of revolutions the output shaft or driveshaft needs to make in order to spin the axle one complete turn.

The number is expressed in a ratio, which represents the number of teeth on the ring gear divided by the number of teeth on the pinion. A lower (numerically higher) gear ratio, such as 3. Axle ratio is defined as the rotational ratio between the transmission shaft- which run by the engine, and the drive axle of the vehicle- which rotates the wheels.

The axle ratio depends upon a lot of factors, some of them including- gross weight of the vehicle, fuel economy to be achieve power to be transmitted to wheels, type of vehicle (medium, heavy duty), gear ratio and more. The axle ratio represents the comparison between the driveshaft which is a component responsible for transferring torque power and the drive axle rotations or revolutions. As seen below, there are only codes (- 5) and they do not define the axle ratio nor capacity.

This proportion is known as an axle ratio. Axle ratios may be expressed in notation as something along the lines of “3.

In either case, it essentially means the drive shaft and pinion need to rotate 3. The rear axle ratio of your car is instrumental in determining which transmission gear set is best suited for your car. It is also important to know the ratio as well as tire size to determine which speedometer gear you need so your speedometer reads accurately.

By following these directions, you can determine what the axle ratio is in your car. Understanding Axle Ratios Automakers build trucks with a range of optional axle ratios.

When filling out the custom tune form, make sure to fill in Axle Ratio only if you know what your axle ratio is. Those ratios provide very good acceleration with gas V-8s and diesels.

When you combine a non-overdrive transmission with a 4. Could any one help me identify the Axle Ratio ?

Rear axle ratio is the overall number of revolutions the driveshaft or output shaft makes to spin the axle one complete rotation.

It refers to the number of gears in a truck’s differential, the machine that links the driveshaft to the rear axle and then to the engine. For example, if a 3. When determining the axle ratio in a Dodge Ram for the purpose of changing to a different ratio, several things should be considered.

On newer vehicles, the shift points in the transmission, the speedometer and the cruising rpm will change accordingly.

The axle ratio is the ratio of the numbers of turn the drive shaft turns,to get one turn of the wheels. Identify your GMC or Chevrolet rear end gear ratio by the RPO Codes, usually located on the placard labeled “Service Parts Identification” inside the drivers door panel or glove box. Or, change input variables (engine RPM, axle gear ratio and tire height) to determine vehicle speed in each forward gear.

Please refer to the Gear Ratio calculator to determine your rear end axle differential ratio. Find a Spicer parts distributor today, or find where you can place your order now on Dana’s streamlined eCommerce platform, DanaAftermarket. Not all applications will have one of these codes but when they apply, they will be listed in addition to an axle code found in the main RPO axle code list below.

GM RPO Axle Code Notes. The axial ratio is the ratio of orthogonal components of an E-field.

A circularly polarized field is made up of two orthogonal E-field components of equal amplitude (and degrees out of phase). Because the components are equal magnitude, the axial ratio is (or dB). I am now second guessing if I selected the wrong axle ratio.

I will probably never tow anything with this truck, and drive around 10miles a year. My main concern is the 3.
