What is inter axle diff lock for?
Use the lock position only when you approach conditions where one or both wheels of an axle may slip. The valve locks the differential and causes it to act as a “through drive,” transmitting power equally to both axles. Avoid unnecessary use of differential lock since it will result in tire wear and axle strain.
Can you drive with diff lock?
When differential locks are engaged on a vehicle, how fast can you drive? You should not exceed 25mph with diff locks engaged. Differential locks allow the driver to force the vehicle to use all (or both depending on where the locks are located) tires while making a turn.
What’s the difference between axle lock and differential lock?
Interlock locks the differential between the axles. You will still spin the tires with the least traction on each axle. Differential locks lock the differentials in each axle. Both wheels on one axle will turn the same speed, but the power will go to the axle with the least traction.
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.
How does a diff lock work on a car?
When the diff lock is engaged, it positively locks the wheel differential to provide improved traction under adverse road conditions. The differential lock is controlled through an electric switch or air valve mounted in the cab. The locking mechanism is air operated to engage a mechanical clutch that locks the wheel differential.
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.
