Final Drive Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Final Drive Ratio = Rear Gear Ratio*Overdrive Ratio
F = G_rear*O′
This formula uses 3 Variables

Variables Used

Final Drive Ratio - Final Drive Ratio is defined as the ratio of how many times the pinion rotates for every rotation of the car's wheels.
Rear Gear Ratio - Rear Gear Ratio is defined as the number of teeth on the ring i.e. driven gear divided by the number of teeth on the pinion i.e. the driver gear.
Overdrive Ratio - Overdrive Ratio is defined as when the output rpm of transmission is greater than the rpm at input of transmission and the ratio will be less than 1.

STEP 1: Convert Input(s) to Base Unit

Rear Gear Ratio: 4 --> No Conversion Required
Overdrive Ratio: 0.65 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F = G_rear*O′ --> 4*0.65

Evaluating ... ...

F = 2.6

STEP 3: Convert Result to Output's Unit

2.6 --> No Conversion Required

FINAL ANSWER

2.6 <-- Final Drive Ratio

What is final drive ratio?

The Final Drive Ratio is the ratio of how many times the pinion rotates for every rotation of the car's wheels. The higher this number, the more times the pinion rotates per turn of the wheels, producing more torque and acceleration but less top speed.

How to Calculate Final Drive Ratio?

Final Drive Ratio calculator uses Final Drive Ratio = Rear Gear Ratio*Overdrive Ratio to calculate the Final Drive Ratio, The Final drive ratio formula is defined as the ratio of how many times the pinion rotates for every rotation of the car's wheels. Final Drive Ratio is denoted by F symbol.

How to calculate Final Drive Ratio using this online calculator? To use this online calculator for Final Drive Ratio, enter Rear Gear Ratio (G_rear) & Overdrive Ratio (O′) and hit the calculate button. Here is how the Final Drive Ratio calculation can be explained with given input values -> 2.6 = 4*0.65.

FAQ

What is Final Drive Ratio?

The Final drive ratio formula is defined as the ratio of how many times the pinion rotates for every rotation of the car's wheels and is represented as F = G_rear*O′ or Final Drive Ratio = Rear Gear Ratio*Overdrive Ratio. Rear Gear Ratio is defined as the number of teeth on the ring i.e. driven gear divided by the number of teeth on the pinion i.e. the driver gear & Overdrive Ratio is defined as when the output rpm of transmission is greater than the rpm at input of transmission and the ratio will be less than 1.

How to calculate Final Drive Ratio?

The Final drive ratio formula is defined as the ratio of how many times the pinion rotates for every rotation of the car's wheels is calculated using Final Drive Ratio = Rear Gear Ratio*Overdrive Ratio. To calculate Final Drive Ratio, you need Rear Gear Ratio (G_rear) & Overdrive Ratio (O′). With our tool, you need to enter the respective value for Rear Gear Ratio & Overdrive Ratio and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
