What is a final drive ratio?
The final drive ratio is the last bit of gearing between your transmission and the driven wheels. In general, a lower final drive ratio will lead to less torque at the wheels but a higher top speed. Meanwhile, a higher ratio will result in the opposite, i.e. more torque at the wheels but a lower top speed.
How is drive ratio calculated?
To calculate the gear ratio: Divide the number of driven gear teeth by the number of drive gear teeth. In our example, it’s 28/21 or 4 : 3. This gear ratio shows that the smaller driver gear must turn 1,3 times to get the larger driven gear to make one complete turn.
How is diff ratio calculated?
The calculation uses the number of teeth in the ring gear and divides it by the number of teeth in the pinion gear to provide you with a “[result] to 1” ratio. For example, if the pinion gear has 41 teeth, and the ring gear has 11 teeth, the ratio would be calculated as 41/11, which is equal to 3.73 = 3.73:1.
How do you calculate gear ratios?
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).
Is final drive ratio the same as axle ratio?
Final drive ratio and axle ratio are one and the same. “Final drive” refers to the last set of gears that power goes through before it gets to the wheels. Bye bye, Bumblebee! Final drive ratio and axle ratio are one and the same.
How do you calculate top speed gear ratio?
The gearing formula depicts a maximum gearing situation because it uses maximum engine rpm and maximum vehicle speed….Tire Diameter(Inches) X Rpm (At Redline) 336 (A Constant Number) X Mph (Maximum Speed)
MPH = | Tire Diameter (inches) X rpm |
---|---|
336 X Gear Ratio (must be Final Drive Gear Ratio) |
How do I determine my axle ratio?
Method 1: Count the number of teeth on the ring gear and the pinion. Divide the number of the ring gear’s teeth by the number of the pinion’s teeth. This will give you the axle ratio.
How do you calculate rear end ratio?
Turn the wheel TWO revolutions and count the number of driveshaft turns. The number of driveshaft rotations will help you determine your rear axle ratio. For example, if it turned 3 and a half times, it’s a 3.50:1 ratio. If it turned 4 and a quarter times, it’s a 4.25:1 ratio.
How do you calculate rear end gear ratio?
Count the number of teeth on the pinion gear and count the number of teeth on the ring gear. Divide the ring gear teeth number by the number of teeth on the pinion. The result is your gear ratio. Note: you may need to round off the number.
How to calculate a cyclo drive gear ratio?
Find the Motor RPM. First,you need the motor RPM.
How do you calculate a golden ratio?
Measure the width of each eye and the distance between the eyes. The ideal proportion occurs when the distance between the eyes is equal to the width of each eye. Measure the length of an ear, which ideally would equal the length of the nose, according to the golden ratio.
How do you calculate gearing ratio?
The net gearing ratio is calculated by: Net gearing can also be calculated by dividing the total debt by the total shareholders’ equity. Expressed as a percentage, the ratio reflects the amount of existing equity that would be required to pay off all outstanding debts.
What is the final gear ratio?
Typical final drive ratios can be between 3:1 and 4.5:1. The gear box fitted between the engine and the final drive has variable gear ratios including overdrive and reverse to cater for different speed, power and torque requirements of the vehicle.
