Final Drive Ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
Final Drive Ratio = Rear Gear Ratio*Overdrive Ratio
F = Grrear*Or
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 = Grrear*Or --> 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

Angular Acceleration of Driven Shaft
Go Angular Acceleration of Driven Shaft = -Angular Velocity of Driven Shaft^2*cos(Angle between Driving and Driven Shafts)*sin(Angle between Driving and Driven Shafts)^2*sin(2*Angle Rotated by Driven Shaft)/((1-cos(Angle Rotated by Driven Shaft)^2*sin(Angle between Driving and Driven Shafts)^2)^2)
Velocity Ratio of Hooke's Joint
Go Velocity Ratio = cos(Angle between Driving and Driven Shafts)/(1-(cos(Angle Rotated by Driving Shaft))^2*(sin(Angle between Driving and Driven Shafts))^2)
Percentage Gradeability of Vehicle
Go Gradeability of Vehicle = (10200*Torque Generated*Overall Gear Reduction)/(Rolling Radius of Loaded Driving Tire*Gross Vehicle Weight)-Percentage Rolling Resistance
Axial Force of Multiplate Clutch using Uniform Wear Theory
Go Total Axial Load = pi*Pressure of Intensity*Inner Diameter of Friction Disc*(Outer Diameter of Friction Disc-Inner Diameter of Friction Disc)*0.5
Aerodynamic Resistance
Go Aerodynamic Resistance of Vehicle = 0.5*Density of Air*Frontal Area of Vehicle*Cruising Speed of Vehicle^2*Coefficient of Drag Exerted by Flow
Drawbar Pull
Go Drawbar Pull = (Torque Generated*Overall Gear Reduction*1000)/Rolling Radius of Loaded Driving Tire-Rolling Resistance at Wheel
Power Required to Propel Vehicle
Go Power required to Propel a Vehicle = (Total Resistance on Vehicle*Speed of Vehicle in Meter per Second)/Transmission Efficiency of Vehicle
Weight on Rear Axle
Go Weight on Rear Axle = (Total Weight being Distributed of Vehicle*CG Distance from Front Axle)/Wheelbase of Vehicle
Total Resistance on Vehicle
Go Total Resistance on Vehicle = Aerodynamic Resistance of Vehicle+Rolling Resistance at Wheel+Gradient Resistance
Effective Gear Ratio
Go Effective Gear Ratio = Old Tire Diameter/New Tire Diameter*Gear Ratio of Transmission
Weight on Front Axle
Go Weight on Front Axle = Total Weight being Distributed of Vehicle-Weight on Rear Axle
Engine Torque
Go Engine Torque = (9.55*Power required to Propel a Vehicle)/Engine Speed in rpm
Gear Step
Go Gear Step = Preceding Lower Gear Ratio Number/Gear Ratio Number
Final Drive Ratio
Go Final Drive Ratio = Rear Gear Ratio*Overdrive Ratio

Final Drive Ratio Formula

Final Drive Ratio = Rear Gear Ratio*Overdrive Ratio
F = Grrear*Or

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 (Grrear) & Overdrive Ratio (Or) 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 = Grrear*Or 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?
