Audi Designers?

[Rippthrough 98]

A while ago, on a 205 near you:

 

 

 

 

 

 

This week:

 

 

 

They didn't even have the courtesy to change the shape, cheeky fckrs!

Did you watch the Chris Harris video today!?

[Batfink 201]

whats the benefit of this design again? I'm guessing its pretty obvious looking at the wear marks on the 205 discs....

Weight less, according to that Chris Harris video, 3kg less each corner

I popped the link on phill's FB wall

[Edp 67 3 Cars]

what audi is that?

[welshpug 1,657]

B8 RS4

 

its got wavy discs on the back too.

Never understood these discs, they have a smaller contact patch and how do the pads not "clip" the disc when spinning at high speed as they're no always going to be perfectly straight...

On mountain bikes it's done to help clear dirt out and it supposedly helps the rotor to cool down faster. On road vehicles, it's mostly just done for show, hence MotoGP and F1 rotors looking like this:

Yer but they are carbon discs..

Money saving then if they had waves... Not that they're fussed about a few quid lol

[24seven 104]

What does that change? We're talking about the shape not the material.

[kyepan 291]

Simply that the weight saving is not required because the carbon discs are very light already.

[BlueBolt 156]

The only real reason would be for weight saving, which they kinda kick the ads out of with the carbon.......???

 

Edit::

Got beat to it lol

I doubt you would want a pad to be eating across the edge of a laminated carbon disc,

back to the original question, I would not be suprised if big car companies occasionally had a browse of some of the more technical based car forums (which I like to think this one usually is) for a bit of 'free inspiration'. I know plenty of other industries keep a close eye on what the smaller sects of the market are up to. and its much easier to pilfer ideas if theyve not been copyrighted/trademarked/patented!

You'll never be an F1 engineer, that's for sure!

 

Rule #1 - nothing is ever "light enough already".

Is the second rule about never touching another mans slide rule?

 

A small misquote my good man, but a world of meaning away, I said very light, not light enough. the devil, as i'm sure you are aware, is in the detail. I already performed a strucutural integrity anal-sys on that disc in photoshop, and it could have been scaled down a bit using the transform tool without looking s*it.

 

Actually i would consider a career in motorsport, i sent Mclaren my CV, but they must have lost it in the post as they never called back.

 

 

I design information architecture, you design exhausts (or so i heard). it is our lot in life.

in F1 its light enough when lighter breaks...

Swing and a miss.. I design suspension.

 

Very light is still not light enough, there is always weight to be saved.

That was Colin Chapman's mantra wasn't it? Make a part lighter and lighter until it breaks, then go back a step.

I think his quote was make it lighter until it breaks, then make it lighter still, hence why so many of his cars broke down and didn't finish races!

 

 

The wavy design could also be to increase surface area to help with cooling?

[24seven 104]

Didn't he say that the perfect car would be light and fast enough to cross the finish line first, then immediately completely fall to pieces?

 

Not that it matters... But anyway if someone can find a good, properly investigated/tested/proven reason why wavy discs are better on a road car than ordinary ones, fair enough. But until then I still think that if the shape offered performance benefits other than dirt clearing, you'd see them in F1/MotoGP. I'll ask some of the M'cycle degree boys at uni if any of them have looked into this next time I see them.

[Batfink 201]

they are lighter...thats all that really matters

Balsa wood is lighter than Aluminium but you don't see pistons made out of it. wavy rotors may well be lighter, but at what cost?
