American trucks don’t have wheel level individual springs. The individual
wheels are typically unsprung, and ride in a truck frame that has springs
either at the center beam (for freight) or at multiple places in a larger
truck frame (for passenger). SOMETIMES there will be a spring between the
journal box/bearing and the frame, but (almost(1)?) never one on each side
the way LEGO molded it.
J2, among others, has made models of american (bettendorf or AAR) trucks by
taking the wheels out of the wheelholders and building something else up.
That LEGO wheel is probably more representative of a 19th century european 4
wheel car’s wheel arrangement than anything else.
1 - never say never, there’s always a prototype somewhere. But I speak of
common practice.

Yes, I’ll agree that the US doesn’t really do four wheel vehicles However I have
never really thought of the Lego wheelsets as being European as they have coil
springs when the style of suspension with W irons represented had/have leaf
springs More modern four wheel veicles that have coil springing don’t have the
W irons and bogie vehicles with coil sprung primary supension have never had. I
suppose that one of the GWR wagon bogie designs might look a bit like a pair of
the Lego wheelsets but not much and it s getting pretty obscure Thus I don’t
think the Lego wheelsets are Euro either!
