The Complex Truck Configurations “YOU NEVER” Heard Of

The Complex Truck Configurations “YOU NEVER” Heard Of

To know the difference between the different types of trucks, and to know how many wheels it has, whether they are towing, and whether the axle is rotatable, you use axle configuration numbers that tell you which vehicle you are dealing with.

However, there are some very unique truck configurations most people don't know about..

If you want to learn even more about truck configurations we made a video called: All Axle configurations explained, going through every single truck configuration so go watch that:

You used the term "rotatable" again... the intended meaning of this is not clear. It could mean "driven", or it could mean "steered". Of course the wheels on any axle rotate.

[danielhahn]

Oh there's so many more configurations, dependent on what customers need :D

The selection of axle formula is based on a few things specific to application.
The number of axles is based on weight mostly, more axles enables more load. Placement of those axles depends on weight distribution. Heavy load in the back = more axles in the back, often leads to steerable rear axle.
Load can be large and light, small and heavy, or any other config, leading to vastly different axle arrangements.

More axles does NOT equal more traction. More traction is achieved by more weight on a specific axle, which can be multiplied by putting even more weight on even more axles. Thats why HETs/Prime Movers that work with push/pull rods have ballast bridges. To load their many axles better.
Those come in ultra-short 8x4/6 configurations up to 10x6/4. Look pretty funny.
Also hydrodrive only works up to 25km/h 😊
Number of steerable axles depends on area of employment of the truck and thus minimum expected turn radius (extreme case: logging trucks)

I engineered many such trucks while working at the custom engineering department at MAN

Tatra makes a 10x10/8 truck and those are quite manouvrable

6x2 are notorious for getting stuck in spoon drains and quick elevation changes eg intersection or driveways with road height change. Either have to lock the diff if equiped or dump the lazy axles airbag.

[brianb-p]

The illustrations of the 8X2-6 at 2:55 and 10X2-6 at 3:49 have the rearmost axle steering the wrong way.

[Werry_Rang]

Yo my bicycle is 2x1 is it any good?
I'm wondering if I should upgrade to 2x2.

[TruckSpottingDambovita]

2:53 the back axel needs to be opposite from the front

[CySaturnTVObjectCosmos]

Theres also 10x6-4 means its uncommon in Australia
And 8x6 means its common in Australia and rare in america

[DouglasWalrath]

i wonder how much more efficient a 10x10 could be if it used electric wheel hub motors, removing all the transmission and axle losses

[Low]

Definitely know the difference. More fun is twin steer, 8x4, and twin control 6x4 but two steering wheels, lh and rh. Especially when the fleet has the same vehicles but 8x4 and 6x4.

Airtek front suspension. No thanks.

[osku]

Here in finland most common chassises propably is 6x2*4 or 6x4. but also 8x2*6 and 8x4 is also used especially in soil transporting.

[GOOD_FARMER]

You forgot about 10x2-4 and 12x2-8 again

[karelvvv]

I think DAF has the best system for telling what kind of configuration of axles you have, for example FAN is a 6x2 rigid with a stearable tag axle behind the driven one

[jaysmith]

United States-excited about an 8x6
Europe-doesn’t bat an eye for a 6x2/4-16

Keeping it simple is straight out the window

And the only vehicle I have ever seen with a non fixed tag axle is a motorcoach. Raising them, or even unlocking them for turning, really screws with the handling. If you have a 6x2, the first drive axle is almost always powered, so you don’t need to run the driveshaft through an axle, unless it has a liftable axle, then the rear axle is driven, since you can’t lift it anyways.

[bartek]

I often see 6x2/4 turning. They seem to be more maneuverable than 4x2. I don't have a data though.

[brianb-p]

You missed the steering configurations of the 10X10. At least some of the examples which you show steer axles #1, #2, and #5, making it presumably a 10X10-6, following earlier examples.

[marinavoronkova]

Now completely confused/
At 1:15 you tell, that -X, (as well as *X) means liftable "wheels", while /X means steering wheels. All the rest of the video you do use -X to indicate steering wheels. Did I miss something?

I was surprised to see only 42 likes on this video until I realized it was published like half-hour ago😆

[outlawdingo]

We have tri drive kenworth 909's one steer axle and three drive axles that need the whole Atlantic Ocean because they turn like a cargo ship

[tba]

Not all exactly true, eg 6x4 has 2 drive axles but only one wheel drives until the power divider and diff locks are engaged. If all the wheels drive at the same time you won’t turn on bitumen and destroy the diffs. Only designed for poor traction situations.
