What in the ham sandwich are these pictures! Is this real?! 😳
Frightening isn’t it?
Real photos scanned from contemporary road tests!
The swing-axle scenario plays like this:
The wheels develop massive camber change under load as those swing-axles ‘tuck under’ which, as you see, dramatically narrows the track causing the rear to ‘climb up’ - like the proverbial
stink bug in heat - a potentially deadly ‘worst of the worst’ drama combination!
The next step is either
very sudden snap-oversteer, and then in extremis the massive camber change will induce the tyre sidewall to partially collapse, as it now carries all the load - witness the nightmare 3rd photo of that Spitfire Mkll which appears
very close..
This leads the outside edge of the wheel rim to literally dig-in to the pavement (or in combination), may also blow out the tyre.
And when that happens, my friend, you are dead-set cactus!
You can clearly imagine what happens next...
Mate I’ve got an old UK magazine somewhere which featured an in-period Family Car Test Comparison of four different vehicle Brands, with each vehicle employing the dreaded swing-axles. There’s a 2-page spread entirely devoted to photos of each vehicle while cornering... as doom fast approaches. It’s a jaw dropper for sure
[edit] iirc: Triumph Herald, VW, Renault Dauphine, Skoda Estelle.
Btw I used to own a 1955 Beetle Standard (the base-model ‘stripper’) which was equipped with this thrilling combination:
Swing axles.
125 mm crossply retreads on 3 1/2” rims.
Cable brakes - that’s right, NO hydraulics - just like a push bike!
Btw VW also thoughtfully positioned the fuse box
directly atop the petrol tank..
So basically, in a superbly choreographed
coup de gras, if the swing-axles didn’t kill you 💀 the subsequent rollover inversion meant you’d surely burn to death 🔥
