What is an inter axle lock?
A power divider (also known as an Inter-Axle Differential or IAD) is a separate differential box that locks the first and second differentials in a tandem truck into place. This allows all drive wheels to movie at the same speed.
What is differential lock in trucks?
Locking differentials (generically referred to as “lockers”) can lock the axles together to provide 100% of available torque to the wheel with traction. During turns, a locking differential operates like an open differential – the wheels can rotate at different speeds.
What is axle lock for?
This vehicle is equipped with electronically locking front and rear differentials. These differentials, when engaged, mechanically lock together the axle shafts forcing the wheels to spin at an equal rate. This allows the vehicle to maintain its momentum and prevents it from becoming stuck.
How does an inter axle lock work on a differential?
So, the inter axle lock will lock the axle together to each for 50% power to each axle not matter what. Differentials will only lock in the tires on the axle to each get 50% of the power sent to the axle. With them both of them on, you can pretty much get yourself out most situations.
Why does an inter axle lock cause a car to spin?
Just like a differential that will send all the power to the on wheel that is in the air (less traction) instead of the on the ground, the inter axle lock will do the same the thing with the axles. Which why when stuck in mud or on ice, you will see one axle spin.
Is there an inter axle lock in OTR?
Good question. Most OTR drivers are never in a truck with both. Almost always you only have an Interaxle Differential Lock (IAD Lock), which is also called a power divider. A tractor with two drive axles has three differentials. This locks the differential BETWEEN the axles. It distributes power to both axles.
Which is better diff lock or inter lock?
That pair of drive axles will pull together with the inter lock. With diff lock both sides of the primary drive, usually the first one will pull together. But if you throw both on… that thing will forget how to turn right or left worth anything.
