The primary purpose of rear end gears is to multiply the torque the engine and transmission delivers. Gear systems have developed over the centuries and are readily divided into dynasties.

To change the rotational motion to a different axisĪlthough gear systems came into play as far back as four ages BC in China, many still believe that the first invention could be much older.

To synchronize the rotation and keep it that way.

To decrease or increase the rotation speed.

To accurately reverse the direction of rotation.

Gears became functional for any of the following reasons:

The wheel was first invented before the gear came into play. Regardless of how many idlers there are within the train, the final gear ratio is between the ‘driver’ and the ‘driven’ wheel. You can easily apply the gear ratio formula to every pair of wheels, but the truth is that you do not have to do so. The rear end gear ratio has to do with the relationship between the pinion gear and the ring gear.īut is there a chance that the system may incorporate more than two elements? Yes, the intermediate gears are known as ‘idlers.’ They can be used to keep – or change – the direction of rotation. In other words, for every single turn of the ring gear, the pinion rotates 4.10 times. Therefore, this implies that a ring gear with 41 teeth and a pinion with ten teeth results in 4.10:1. This ratio refers to the number of teeth on the ring – i.e., driven gear – divided by the number of teeth on the pinion – i.e., the drive gear.

When you hear car drivers refer to numbers – such as 3.08:1, 3.73:1, or even 4.10:1 – they discuss the ring-and-pinion gears’ ratio within the rear axle. When you multiply the two ratios, it equals the final drive ratio. Most automobiles use gear ratios in the drive axle and the transmission to multiply power. Let’s get started with the basics, shall we? What is a Rear End Gear Ratio? Let this article serve as a guide or flashlight into this universe, and you will never get lost. However, if you understand precisely how it works, your choice becomes much more calculated.

Knowing how to calculate the rear end gear ratio to choose the right one is not a must but an advantage, and this is because you can find the gear ratio in the product description. The first time you wade into the gears’ universe, you will encounter several terms such as gear ratio, rear end, gear systems or ‘trains,’ etc. Rear end gear ratio is boiled down to lower numerical values giving better acceleration, torque, top speeds, and better fuel economy.
