final drive ratios explained

This is known as the final drive differential gear Crown Wheel Pinion CWP or ring and pinion. A lower taller gear ratio provides a higher top speed and a higher shorter gear ratio provides faster acceleration.

The ring gear has 50 teeth and the pinion has 11.

. The final drive ratio is typically the gear ratio for the differential or the final location where the gearing is altered before being sent to the wheels. The final-drive ratio is the extent to which the rotating speed of the driveshaft output from the gearbox finally reduces before it reaches the driven wheels. For example if the ring gear has 30 teeth and the pinion has 10 take the number 30 and divide by 10 to get the ratio of 31.

Familiar final drive ratios for powerful cars include 3081 40 crown wheel teeth and 13 pinion teeth and 3091 3411. Familiar ratios in smaller cars are 3891 359 and 4111 379. The smaller the wheels the greater the force.

Large family saloons may have 3311 4313 or 3451 3811. The straightforward way to calculate the Final Drive Ratio is to divide the number of teeth on the ring gear by the number of teeth on the pinion gear. Changing the final drive ratio heavily impacts the way the car behaves.

Choosing your right gearing is all about compromise. Heres what you need to. In the image below we have 50 teeth on the ring gear and 11 on the pinion so the formula looks like this.

When you multiply the two ratios it equals the final drive ratio. Thinking about swapping out your motorcycles sprockets changing the final drive ratio. Most automobiles use gear ratios in the drive axle and the transmission to multiply power.

The final drive ratio is just like any other gear ratio in that its essentially a torque multiplier. Because the average manual-shift transmission contains more than one pair of gears the same formula holds true for each drive and driven set. A 373 ratio is suitable for regular light towing.

Manufacturers design vehicles with a final drive ratio that can provide a good compromise providing reasonable acceleration lower gearing and good highway speed at a practical engine speed. Rear end gear ratios or final drive ratio refers to the number of revolutions the drive shaft turns compared to one full revolution of rear wheels. But if you want better acceleration or more top speed there is an easier solution to your problem.

The ratio of each drive and driven set is multiplied by each other to give the final ratio. A 290 gear ratio means the drive shaft turns 29 times in one full turn of the rear wheels. The 373 final drive ratio is part of a heavy-duty towing package and comes with changes to tires and other elements.

Change your final drive ratio. If you alter this ratio it also alters every gears effective ratio thereby affecting the vehicle performance and economy. You divide the number of teeth on the ring gear by the number on the pinion.

The gear ratio of the set is 4541. Besides the gears in the transmission there is also a gear in the rear differential. A 41 ratio allows a towing vehicle to start moving without as much throttle.

Hence the manufacturers term it as the final drive ratio. Technically the number should be expressed as a ratio such as 3551 meaning the drive shaft turns 355 times for each turn of a wheel. Final Drive Ratio.

Source Mike Aguilar. The gears within your transmission arent the. Moving from the 342 to the 308 final drive ratio the fuel economy in mixed driving can improve mpg by up to 10 mpg in typical highway driving but wont change.

Motorcycle Sprocket Gear Ratios And Changes Explained. When you hear car drivers refer to numbers such as 3081 3731 or even 4101 they discuss the ring-and-pinion gears ratio within the rear axle. But that gear ratio would most commonly be referred to as.

If you plan on towing a fifth-wheel trailer or anything heavier than 5000 pounds you should consider a 41 axle ratio. Today with the new 6-speed transmission we offer from a 308 to a 373 final drive ratio. What is a final drive ratio.

I read one definition saying its the turns of the engine to the turns of the wheel but that only proves to me that for instance if the final drive ratio was 101 with a car that redlines at 5000rpm then the wheels can turn at a max of 500 rpm thereby limiting top speed. The bigger the ratio the greater the torque. What does changing it doCar Gears - httpsyoutubebgGgH0j0KQESubscribe for new videos every Wednesday.

If you increase the final drive ratio each gear will have greater wheel torque while sacrificing top speed. The same goes with the wheels by the way. Two common base axle ratios for trucks are 308 and 342.
