Admittedly not a particularly exciting image, however it does label and show and the standard points of a tractor trailer truck quite well, and that I judge is worth a shot here.
The WABCO 3200 was a rare example of a tri-axle haul truck configuration A medium sized haul truck, the 214-short-ton (194 t; 191-long-ton) Caterpillar 789 [1].

The next Euclid design was an articulated, tractor/trailer, in the style of the Caterpillar DW10 bottom dumper.
