I would like to know if any one has an upright assembly drawings , in solidworks , its really importatnt , so if you got kindly post it . Thank you



Having a big time problem in getting the assembly right .

Ha ha ha ha...
Don't tell us now you need it for formula student.

Do your homework yourself.

If you're having trouble, post your drawing and explain the problem and we might be able to help when we've seen the extent of your efforts.

Can you believe that people designed FSAE cars before the internet!! The first year I was involved we only had AutoCAD 2D!

I'm fully aware that India, Japan, etc have grown their industries on the basis of copying and improving(?) Western products, but it doesn't make it any less annoying to see it up front.

Japanese teams at least make their own thing, despite sometimes how wacky they may be in the earlier days. Upright in general should be fairly simple. Especially if this is a conservative attempt at the first one. You know your points(I hope), you know your wheel bearing size, you know the brake system you are using and you know how much space you have inside the wheel. Just draw something and connect the dot first, then think about optimizing it. That way at least you'll have something....

You shouldn't be designing upright anyway unless you have most if not all of those somewhat defined....

I agree. The upright will be dictated mainly by the components that attach to it. Then just lighten after you've done that.

Mate, lucky you didn't post this on fsae.com. I think I would see the flamage from Germany...

But seriously, I have loads of upright drawings. Are you after a particular colour? Or will any colour do? If any colour is ok, I have lots in mission brown.

...or Australia, Pat Clarke just shot off a big one on the thread regarding the Indian teams....and he's pretty spot on....as expected really from a design judge...

Why is it really important? What is the big problem you are having?

Let us know more about that and I am sure the community will be more than happy to help. Its just rude and unethical to ask for designs.

Yeah, because in the intervening years the FSAE community has become sick of people (predominantly from India I have to say) not just asking for answers, but demanding answers to very general questions with no evidence of any initial research being carried out.

Rather than being dismissive I've suggested that if you post some indication of your work so far with some detailed, specific, polite questions about how you could improve I'd be happy to try and answer them. Rather than getting in a strop why don't you just post your CAD and ask some questions?

I was doing research on uprights the just other day.

the upright can be casted.
Steel plated.
Or CNC cut.


Here is a steel plate upright with bolt on top mount too.

here are a few more pictures.

If you decide that you just want ANYTHING right now;
I have two freshly made solidworks assemblies. They are made for full size cars though and they are basically a flat piece of aluminum that is machined out and the top ball joint mount is bolted on. The tie rod arm can be bolted on too. I can send you the files but use it at your own risk. The sketch is complex and you have to put in your caster angle, the king pin angle just depends on how far back you bolt the top ball joint mount on.

It is designed similar to this.

I think it's better to have a basic sketch though.
Make space for the bearing (get a bearing) and brakes.
decide the King pin angle.
decide the caster angle.
decide how high or low the joints are from the ground.

and you are halfway there.
