Steering rack

[teddys]

Excuse me, but I don't know English very well and I cannot understand from the FiA technical regulations if steering rack is a member of F1 car's suspension system? I want to know if steering rack itself must intersect a straight line between the inner and outer attachment points as well. The question is a bit strange, but it regards an idea of mine, that I want to share with some of the teams in case steering rack is NOT a member of suspension.

the intersection between two points should always be a straight line -to which reg are you referrring?

[teddys]

It comes to ARTICLE 10 : SUSPENSION AND STEERING SYSTEMS-I can't understand it. So the intersection between 2 points of the steering rack should also be a straight line, right? Or this rule does not refer to the rack?

[marcush.]

intersection of two points? you may have coincidence put you cannot intersect points ,can you?

[teddys]

I think we cannot understand each other, but I know it's my fault, so please excuse me... I'll try to explain it otherwise:
Is it permitted that the steering rack have protuberances on it, or it should be completely straight between the inner and outer attachment points?

[marcush.]

You are not speaking of the rack but the track rod are you?

[teddys]

I mean the parts of the front suspension that connect the steering system with the wheels. The visible "sticks" which come out from the nose cone and force the front wheels to turn and thus make cornering possible. I thought they are "steering racks" (this is how Google translate translated it into my language).

[teddys]

The fact that Article 10 says: "SUSPENSION AND STEERING SYSTEMS" makes me think, that FiA consider them both as two different parts of F1 car's construction. That's why I'm asking this question...

steering rack is the middle part of it


I said track rod in this pic it´s called tierod -maybe english vs amercan english?

[teddys]

So yes, the track rod was the part I meant all the time... So is it permitted that the track rod have protuberances on it, or it should be completely straight between the inner and outer attachment points?
Thank you by the way for the drawing and the explanation!

[marcush.]

as I understand you can change the crossection as long as you respect the maximum aspect ratio of 1:3.5 and the main axis is not more than 100mm -I understand this as the maximum width of any suspension member ,each leg of a wishbone is seen as a separate part.and it has to be symmetrical to the main axis of the part!

So a 100mm trackrod needs to be 28.6mm thick but you could in theory make it 100x99mm in crossection...and you are not allowed to stick parts to it that are not structural....so a simple fence is not allowed outside the bodywork regs envelope.
but having it wavy is possible´I´d say as long as the part remains symmetrical in crossection.

Thank you one more time Marcush !
Your answer really helped me a lot !
