Trulli's accident

[Monstrobolaxa]

Well 2 minutes ago Trulli had his spectacular accident....it seems that all is ok with him.

looking at the replays it seems to me that it was caused rear tire puncture....or a rear suspension failure....inicially I thought that he might have lost the rear wing....but looking carefully it doesn't seem that he lost the rear wing....

The thing about the accident is that he was almost in a straight line and the car snapped right. If he was 100% straight I'd say it was the right rear corner that had the problem. Since he was still turning slightly to the right...the left rear corner was still under load....so we'll have to wait for Renault's report.

But to me....it was the left rear corner...or tire or suspension.

Your opinions.....

right hand side driveshaft/CVjoint snapped I´d say.loosing drive on one side could would transfer all available torque to the outside tyre instanty,depending on differential system this would explain the sudden snap .
A broken suspension link (track rod )would have steered the car towards the right but you would have seen this as it would have been the outward rear affected.
I saw the outward rear tyre showed typical signs of a puncture ,the wheel still attached to the car...but how would trulli make the corner on a flat tyre?impossible.he would have lost it on corner entry then.Or would it be possible the tyre blowed out just at the end of the corner,and if then why?
As far as I know the top teams monitor tyre temps constantly so they would surely know of that as the tyre would surely show dramatic temp increase before a blowout....

Yup the drive shaft is a logical explanation to !

About the tire (not an expert) I'd say that it could have it could have a slow puncture and during the bridge corner, under load the side walls of the tire moved (hard to imagine )...but Michelin have had so many problems that anything is imaginable

well the tyre thing seems unlogical to me as you would expect the tyre to give up under maximum load and this would be when maximum sideforce is buildup,I suppose.
Ok,the tyre temps trail the appearance of loads a bit so the maximum tyre temp would come after the maximum sideways gs I´d say.But again you would see that coming on the telemetry and surely feel and nobody would go into Bridge with a tyre at the brink of exploding.
A traction control failure may also contribute to this sort of accident...as you are under lots of load anyway and high revs the loss of rear traction would create a rise in rear tyre slippage ,instant oversteer impossible to catch even for the fastest driver instincts...

Humm...I of the 2 ideas you mentioned I'd say the Cv joint would be more plausable.

The accident looked like the accidents we had in the active suspension era when a high pressure damper broke, or a high pressure line erupted.

But in any case I'm now going for suspension, or the Cv joint as you said.

Thankfully the driver protection worked well, espcially after the flip due to the gravel trap!

Anyone find any good pictures of Trulli's car? I noticed on TV that the right side was opened up with the radiator plainly visible. Also is any hint of driveline breakage viewable? (At least what wasn't caused by the wall impact and flip)

yeah, say what you want about Max (Mosley) but he did a fantastic job of laying down a foundation for safety of F1 drivers. Trulli wasnt even shaken up after that crash!! No headaches, body aches or anything!!

as far as the pic goes, i looked everywhere but couldnt find a decent one
