Aircraft engineers came up with that.
PS: here’s one of the bolt in ball joints:
This is actually a pretty clever idea, way less of a PITA than pressed in joints.

The tooling for this would be very cheap and simple. Also, this would be much faster to fabricate then tube steel A-arms.

That’s certainly A-shaped

I am just guessing how and why they ended up making this.

It literally looks like something someone built in a shed.

I’m not seeing the arms.

My thoughts exactly ... and it seems to be made of various metals, more or less ....

That was the year of the Scania merger.
Might explain it.
Interestingly, we call them wishbones in English.

So far as I know, they’re all like that. The rally cars had a plate welded across the tops of the arms for more strength, but that was it.

I wouldn’t be surprised if the ones in the prototype were any less sophisticated. It probably worked in that, so why not in the production version?

It worked. Why complicate things?

By coincidence, I was just trying to figure out how to approach the bolt-in ball joints in the Niva. Debating simply leaving them, TBH. I ordered new ones this week because an attempt to remove one earlier this year for another reason resulted in three broken bolts, one replacement, and two bolts held in by anti-gravity and/or rust.
Healthy dose of PB on the upper. Shiney new shock in the background, old ones needed cut out. But the “C” with the three nuts on top is part of the a-arm, a cast chunk only a bit less spindly than yours. The bolts feed through from underneath, with the ball joint sitting under the a-arm. In the case of the broken off bolts, no power in the ‘verse could budge them out of their seats, and driving on them for like, 7000km or something stupid didn’t do anything either. Pretty sure they’re now one with the a-arm.
At least with the Saab design you’d break them off and then still be able to pop the old one out...

that is a silly design.

It’s loosely inherited from Fiat.
And it looks like it economises materials pretty well. But I don’t imagine the original Fiat stuff would hang onto the bolts so effectively.
