Differential Lock?
Hello all, does anyone know if there is an option for Diff.Locks for the Tractors? I just delivered a load of Dynamite and backing up the hill in one spot was a little tricky,kept spinning out.Wonder if SCS may have missed it for ATS, as in ETS2 it was not needed anywhere really.

hmmmm good question considering they been standard equipment on most every north american made tandem since the 1970's and still on most every new truck

Have not seen one But Yes Interaxel Lock and /or Diff lock or both could come in handy in places Esp as the map gets bigger god only knows where we may end up . Or if wed see a blizzard

manufactuters use either name , typically north american tandems power the rear axle only the diff lock or interlock puts full power to both, have noticed in game both axles appear powered so maybe they figured it wasnt needed

NOO Dif Lock Does excatly what the name is Locks the differentials , Interaxel lock Sends equal power to the front Rearend that the back Rear is reciving but only one wheel on either axle will spin . but If ya have both ya can lock everything

Tandem axles will rotate at different speeds when cornering, driving over
uneven road surfaces or when equipped with different tire sizes.
The inter-axle differential is simply a mechanism that lets one axle rotate faster
or slower than the other. Under normal conditions it splits the torque evenly
between the 2 axles.
When extra traction is needed under adverse road conditions, you can lock out
the inter-axle differential. With the lockout engaged (LOCK position), the interaxle
differential acts as a solid shaft and does not compensate for differences
in axle speed, but directs the torque to the axle with the most traction.
With the lockout disengaged (UNLOCK position), the inter-axle differential
operates normally.

now i have driven trucks where the axle interlock is labeled as a diff lock , thats quite common and why i stated manufacters use either term . this is espically true on older trucks

I nudged up against a building with a trailer, and gave it some throttle in reverse. To my surprise, all four sets of duals were spinning, and the truck started to "posi" sideways. Looked like the truck had diff lock, and power divider both activated.

Your so lost its not even worth explaining But i will for those who dont Know ,, Differential is in the Rear end it lets one axle spin faster than the other when in turns , On slick surfaces the wheel with least traction will spin , while the other one just sits their ans says Hahhaha,, Diff Lock Locks the Dif solid so Both sides pull at the same time ...... Interaxel lock Locks the Rear Rear with the Front rear . Sending power equaly between the 2 BUT Unless you have a DIFFERNTIAL LOCK , You get hung up in mud or ice Your only gonna get power to one side or the other of each rear end , Where the Diff Lock Locks everything togather and you have full power and equal power to all 8 tires . and dont try to turn cause its not going to LOL........And side note If you ever break a axle 99% of the time its gonna be the back rear end , and to get in a safe spot Lock the Interaxel in and u can move enough to get the truck in a safe spot

your the lost one here, were not debating the function as you somehow think your god like intllenge does. i wa simply stating that manufacturers use either term aspically on older trucks, now if you can prove me they didnt then just drop it. stop playing yourself as a super god like braniac cause if you were you would not be playing video games

You would not drive any distance with diff locks engaged, only use them in situations that would warrant it, like mud or somewhere, where you would have wheel spin.
An "inter-axle lock" is a power divider. Period. It does not lock the differentials. It locks the front and rear axle assemblies together.
An "inter-wheel differential lock" is a diff lock. Period. It locks the diff into full time posi traction.

There is no arguing this. The above is the correct nomenclature. If you've heard otherwise in your travels,then you were misinformed, or you misunderstood.

If you have the power divider unlocked, and you engage diff lock, you have posi traction on the rear axle assembly. If you have diff lock engaged, and the power divider engaged, you have posi traction to both axle assemblies.

djgoober38 is correct. There is no arguing this.

Like i said show me and everyone else here proof that axle interlocks have never been labelled as diff lock by north american manufacturers. go for it, go way to the 60's and get the proof that your correct.

You called it an "inter-axle differential". Not an "axle interlock" in your OP.

That being said, if you were talking about diff lock, which you were, we can all agree that your post stands as being correct. That is in a nutshell, how posi traction works.

The problem with the first post, is you used the proper term for "power divider", but you were explaining how a diff lock works. Good info, none the less. Just the wrong term.

You challenged my statement no back up your claim. get proof
