Threads

Hi All

Not much to do with ME but I was watching the F1 race today in Bahrain and last week from Shangi And Mclaren have had a problem in both races with their wheel lacate and locking nut. There was one shown today and explained that the nut is aluminium and the hub titanium so if it gets cross threaded it just destroys the nut in which case they then just fit ather. Nevernind all the aluminium threads that have got to have gone somewhere LOL. But I was thinking and looking at the nut which looked like a normal thread profile..Would it not be better to either have a shapped thread as in acme or even square And possibly have multi start points so like a twin thread setup.. Did anyone else see it or have you thought about it and have any suggestions?

As I said it just came to me whilst sat watching the race. this morning and the engineer in me just started to run over it in my head LOL

Can't answer your question, but know what you mean. I once asked an F1 pit man about the wheel threads, he said they were just glorified pipe fittings. Maybe there are regulations about them, probably is.

Multi start would be quicker to fit, but less reliably self locking.

I would feel a lot safer keeping to the higher friction single start vee threads. Colin

They said it was aluminium but I expect they use some exotic alloy, but clearly not exotic enough!

Speedy work in the pits is vital. I saw a time of 4.6 seconds. Quite what they did in that time I dont know as I was not properly paying attention btu just think, @ 200 MPH, that was a bit over a 1/4 mile!

Don't know why they don't use a team of scousers for a pit crew.

4.6 seconds for a wheel change? they could do this AND a respray in less time.

Scallywag scousers eh.... 1.2 seconds to put an F1 car onto bricks.... but they would have to be retrained so they didn't run away with the wheels...
