Does a differential change gear ratio?

Differential Gear Ratio determines the number of times the drive shaft (or pinion) will rotate for each turn of the wheels (or ring gear). So if you have a 3.73:1 gear ratio the drive shaft turns 3.73 times for every turn of the wheel. Switching from a 30″ tire to a 35″ tire changes the final drive ratio by about 17\%.

How do I choose the right axle ratio?

Performance. The larger the axle ratio number, the quicker the truck will accelerate. For example, a truck equipped with 3.55:1 axle gearing will accelerate faster than one equipped with a 3.31 axle ratio. Similarly, a pickup with a 3.73 axle ratio will be faster than one with 3.55s.

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.

What does changing differential ratio mean?

Can you change the gear ratio on your truck?

To counteract the effects of larger tires, you can change the gears in your differential(s) to increase the ratio of how many revolutions of the driveshaft it takes to make one full revolution of the wheel (raising the engine rpm at the same speed).

Does changing gear ratio affect torque?

By changing it, you can affect the performance of your car, rather dramatically in some cases. 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.

What is a good rear end gear ratio?

The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy. This is a good ratio for the occasional towing or hauling individual. For a person who tows more often, and heavier loads, the 3:73 or 4:10 may be more appropriate.

Which section of power transmission alters the gear ratios?

Gear reducers, called speed reducers, are a component of many mechanical, electrical and hydraulic motors. Essentially, it is a gear or series of gears combined in such a manner as to alter the torque of a motor. Typically, the torque increases in direct proportion to the reduction of rotations per unit of time.
