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.

[@railfans-psi]

Hmm, make sense

[@NineDog]

it means steered in this video

[@NikkiTheOtter]

The - means steering, the / means liftable

[@brianb-p6586]

@@NikkiTheOtter I was referring (quite explicitly) to the video's use of the nonsense term "rotatable", not the dashes and slashes of the notation.

[@surlyogre1476]

@@brianb-p6586agreed, he should have used "steerable" as all wheels are _rotatable_ .

[@KevinJD2030]

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

[@danielhahn55]

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

[@tba3900]

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-p6586]

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

[@TruckTropia]

Ohh true 🫣 sorry, Well spotted

[@user-ig1xo3om2x]

@@TruckTropia Oh yes, and the 8X2-6 with 3 axle bogie is usually known as a "tridem" in Europe these days.

[@brianb-p6586]

@@user-ig1xo3om2x "Tridem" is in general just any group of three axles, just as "tandem" is a group of two axles. It can imply that all axles in the group are driven when applied to a tractor, but it's not consistently used.

[@user-ig1xo3om2x]

@@brianb-p6586 Where I've seen it used "tridem" always refers to a 3 axle bogie and a single steer under the cab/engine area. YMMV, so where (nation) do you live? I'm in the UK.

[@brianb-p6586]

@user-ig1xo3om2x I'm in Canada - tridem here normally refers to a three-axle set at the rear of a truck (straight truck or more commonly highway tractor), but can be used for three-axle sets on trailers.

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

[@Mladjasmilic]

I have 2x2 bike (e-bike with front motor). It is epic to ride in mud and sand.

[@george99247]

@@Mladjasmilic damn never thought AWD bike would be real

[@Mladjasmilic]

@@george99247 It is just 250W limited to 25km/h, but it hand hand accelerator and it can be very useful to straight out. It is weird feeling when riding front wheel drive, but very stable. Only problem being that it wants to go where front wheel is pointed, which made me fall until I got used to it.

[@joggaliforden5138]

@@george99247 There is a company in a america called Christini. Who make AWD kits for dirts and bicycles. All be it. It's not driven by an electric motor, but instead a seris of axles, gears and chains, from where the power is sourced. With bicycles its different. The power is driven from the rear wheel, along an axle through the frame, to a diff, then sent to the front wheel. Very complex and very heavy. I could go on for ages, but I'm not, so sorry. But if your interested in this system you could easily look up "Christini all wheel drive system" and learn everything there is to know about it. It's pretty neat, and another interesting thing about them is US special forces have used there products before. So now you know how good they are. Thank you, have a good day.

[@Kalvinjj]

@@george99247Electrics make it easy, but I've seen some combustion engine freaks out there too, quite interesting.

[@KFC.ROMANIA]

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

[@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

[@aranibiswas2124]

Like a diesel locomotive😂😂

[@Low760]

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.

[@TruckTropia]

Thanks for sharing 💪🚚👍

[@GOOD_FARMER]

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

[@osku9904]

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.

[@TruckTropia]

Thanks for sharing :) Finland is a great trucking country

[@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

[@jaysmith1408]

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.

[@0ptera]

What kind of configuration is 6x2/4-16? 3 axle, 1 driven with front and rear steering I get, but what's the -16?

[@jaysmith1408]

@@0ptera some arbitrary combination of lift and steerable axles.

[@brianb-p6586]

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.

[@bartek05303]

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

[@outlawdingo3020]

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

[@jaysmith1408]

My old company had Michigan tridem trailers in the fleet. Our tractors weren’t set up for them, so couldn’t cycle the lift axle from the cab. They were fine on the road, the extra axle took a good bunch of the shock off the tractor, but if I had to turn, I had to jump out and hit the valve to turn at all. And because the tandems were fixed all the way back, you could rarely scale with the lift axle up.

[@tba3900]

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.

[@marinavoronkova9013]

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?

[@TruckTropia]

- or * mens tag axle, where / is forward axle both Can be liftable

Thank you very much, @@TruckTropia , for propmt answer! So, "-" or "/" is not related to following digit, it is separate piece of information.

In Sweden truck can be 34.5m and weigh 74 tons.

[@MichaelArtelle]

Correct me if I'm wrong here, but in my driver's training, the first number meant the number of axleshafts... Not wheels. Wheels are what tires mount to. A 4x2 would have4 axleshafts, 2 of them are powered... By your logic, an 18 wheeler would have 18 axles... 😮
