Wheelbase the same, the nose doesnt affect the wheel base.

the rear wing is quite big many wind tunnel

If you look at the picture it looks like a big fat duck. Doesn't reallly look fast either..

Wonder if they will use that front wing at the start in melbourne..

Does anyone have a really good pic from the top of the car looking down?

Hi everyone,

Lovely forum you've got here, this is my first post. Just wondering if any of you know what these rods might be:



Are they just supports for the nose cone, or could they serve some other purpose? Perhaps some sort of anti-chop defence against swerving Ferraris?

Thanks in advance,
HJ

[Steven]

my guess is those are the torsion bars that the push rod is connected to.
Thanks to a rotating rocker fixed to that bar, with on one end the pusd rod, and on the other end the anti-roll bar, this is part of the suspension system.

Not sure, but almost
There's a drawing that could help you also on this site in Mechanics>Suspension

anyway, can anyone confirm this?

[scarbs]

Absolutely spot on, they are the torsion bars, they extend further out this year allowing for more wheel movement. Notice also this year the steerign rack is inside the footwell and the mould lines splitting the monocoque into three moulded parts; lower, upper left and upper right.

[Steven]

what are those bars actually made of?
is that aluminium? well I think that would be a little too rigid, but maybe in combination with another metal...

looks very shiny to be steel anyway(could be of course)... maybe Titanium

Thanks guys, I actually had a look at the Mechanical->Suspension page before I posted, but I couldn't find the correlation I was looking for. I guess these bars then are the same as the ones visible in the McLaren picture on that page, but protruding further forward?

So, discarding the fear of biting off more than I can chew, how exactly would those rods provide torsional force against the pushrods? Are they fixed at one end and designed to twist within the cylinders, or would they slide fore and aft against some kind of stopper as the rocker pivots are loaded up?

Thanks,
HJ

The rocker pivots on bearings, the torsion bar is splined at either end, one end attaching to splines in the rocker and the other to the mounting on the front (as we can see). Preload can be adjusted by twisting the mounting or as with Minardi a seperat lever also attached to the spline at the mounting end and adjusted by a threaded shaft tethered one to the chassis. Swapping torsion bars is one of the few times a hammer is seen in the pit, firstly a slide hammer (liek a gear puller) is screwed into the torsion bar and hammers out the bar, refitting is simply push the bar in, line up the spline (need a mechanic to wobble the car) andf hit it home with a hammer, delicate work.

Looking at the Williams sidepods, they are look much smaller than the Ferraris and McLaren. Judging that BMW has the highest revs, that means it produces a lot of heat...so how can they fit a radiator that has to radiate extreme heat onto a smaller side pods? Their side pods is much smaller than Ferrari's but their engine is much more powerful than Ferrari's...?this doesn't make sense.

I just saw this.. pic of the day on F1-live.. check out that exit. Thoughts from those who know?

EDIT by Tomba: There we have the Williams again
