Malaysian Grand Prix 2010, Sepang - Race 3/19

Saw this, wondered if anyone could shed any light on it.....

""Red Bull Racing has confirmed that Sebastian Vettel retired from the Australian Grand Prix after the torque drive between the front left axle and wheel was lost."

Then from the rule book....

9.8 Torque transfer systems :
9.8.1 Any system or device the design of which is capable of transferring or diverting torque from a slower to a faster rotating wheel is not permitted.
9.8.2 Any device which is capable of transferring torque between the principal axes of rotation of the two front wheels is prohibited.

Surely thats not legal then???

I read 9.8.2 to mean you can't have an active LSD at the front. Could it be that Red Bull have brakes in the body rather than on the wheels, and there is a shaft to the body to transfer that torque - is that even allowed? *rambles*

Inboard brakes :eek:

I think they need to read the history books (re Lotus) if they do use them!

hope hamilton can carry this speed into tomorrow quali and the race

sunama · 2 Apr 2010 at 13:19

He will.
But it is also likely that Ferrari and the RedBulls will up their game. The RedBulls are particularly impressive in qualifying.

Unless of course, it rains. In which case qualifying becomes a lottery.

just interested to see if the mclaren ******-duct is working well here.

Pratice 2 speed traps :

Edit: Practice 2 above

Looks like it gives quite a boost. With 2 long straights it should be interesting.
Just watching practice reruns, Crofty was saying the McLarens have been fastest in 8/10 of the sessions so far.

Hamilton must really have braked late to cross the speed trap at that speed.

Or that he just ran a setup with less overall drag...

Very much doubt that it takes the entire length of the straight for the cars to reach top speed.

Or the knee operated duct in the rear wing is working great on this track?

Yeah because Practice times are always a good guide to a race weekend :rolleyes:

I thought that much was obvious, seen as though it works the same for both drivers and is simple to operate. With the long straights here it is an obvious advantage for the McLarens.

What I was pointing out was that Hamilton seems to have squeezed out an extra few kph on the speed trap over Button, both drivers have exactly the same F duct. So therefore I'm thinking that Hamilton is running with slightly less overall downforce.

theres no shafts running from the center of the wheel to the car, so i very much doubt they got a torque transfer system. (or inboard brakes as someone said... mad idea)

what it probably means is that the wheel was spinning freely on its shaft even though the brake was working (locked). Dunno how though?

Gotcha, well spotted.

Lopéz · 2 Apr 2010 at 15:08

Watched those classic highlights on Red Button this morning.

Jesus some of the cars of the last decade have been ugly. I quite liked the "gills" on the Renault R25 but other than that most of those things were pretty horrendous looking.

JRS · 2 Apr 2010 at 15:18

Indeed Lopéz. Aesthetics, for me, probably hit their low point with the '08 BMW.

Here's a thread I like.

http://www.f1technical.net/forum/viewtopic.php?p=130868&f=6

Shows the difference in Newey designs 97 to 09. I won't cut and paste just provide the link. I love how simplistic the 97 car is over the present day. It looks a lot less cluttered. I like how basic the wing is compared to the present day cars.

The FIA should present the teams with a standard rear and front wing and save everyone the money and bother for 0.01 of a second. Give them a low, medium and high setting on the wings and let them choose which one to run at each circuit.

97 was the last cars I could look at and think some of them looked decent.

Thats a nice thread. I particularly liked the engine comparison between now and 13 years back - we now have lighter/smaller engines, but just as much power.

I also took the opportunity to look through some other threads and its amazing how things vary from forum to forum. For some strange reason, the folks over there rate MS so highly that they believe he is in with a chance to win in 2 days time. It would appear that the battering he has taken during the last 2 GPs and also the continued battering he has taken from Rosberg at Sepand, hasnt shaken the confidence of many people's faith in MS's current ability.

Having just finally caught the start of P1 and listened to what Christian Horner said, my understanding of the issue is that there was a problem that allowed the wheel to freely rotate independent of the hub, i.e. the wheel was still attached to the hub, however for example despite the brake being fully engaged, the wheel itself was still able to rotate without any braking force being applied to it.

I hope that makes sense in at least some form!
