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.

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

@@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.

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.

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.

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.

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... 😮
