Again, I've been hunting for this term to no avail.

No context. It's on a list of parts.

Thanks in advance!

drive pin / coupling pin / king pin
Explanation:
Can't be certain without context; the two contexts where the phrase is used are metal machining and tractor-trailer couplings.

In the former, it refers to the pin that drives the workpiece in a lathe when it is turned between centers. It is attached to the driveplate and drives the lathe dog clamped onto the workpiece: http://en.wikipedia.org/wiki/Lathe_dog

it is also used (in Spanish) to refer to the "king pin" part of the tractor-trailer coupling. But that has little to do with "suspension system".

The only other connections I can think of is that the axles supporting the sattellite gears in a car differential are called kingpins: http://www.tpub.com/content/automotiveenginemechanics/TM-9-8...

(but I don't know what they are called in Spanish)

agree  cranesfreak: agree with king pin if we are talking about a fifth wheel system for truck and trailer coupling. The context is too short. Rgds :)

  -> Thanks cranesfreak; in a fifth wheel -- definitely; otherwise all we know it's a pin that is loaded transversally
