solidworks 2010-design a car rim

[nicola1985]

Hello everyone.. .

I have to draw a lenticular rim for a racing car of the type fsae.

I shouldn't have trouble drawing the rim, what I wanted to know is that requirements must have the rim channel so that with the mounted rubber it's okay.

Thank you. .

that requirements must have the rim channel so that with the mounted rubber it is all ok.

. Sorry, but I can't understand the question, you should explain yourself better.
but "to the eye" I would say that the thing has no relevance with the modeling and use of solidworks.
Maybe you should be informed in a more appropriate place.. with a joke < from the gommista>>>:biggrin:

greetings

for now maybe it doesn't have much relevance because I don't know where to leave. . .

once I leave then I will need your advice. . .

the circle I have to draw is a lenticular similar to this:
http://www.pcm.unifi.it/aias2009/memorie/memoria-aias2009-196.pdfThe tyre I have to mount is No.43162 :
http://www.hoosiertire.com/fsaeinfo.htmI need to know what I am in my case
a,b,c,d,g,h,p that are seen in the profile of revolution from which I will leave for the cad.

ps. I don't know about a wedge, but from me the elbows are not engineers...:biggrin:

greetings nicola.. .

Maybe there's a technical data that a gommist can find to help you out.
Try.

Here we go.
do you see that in these terms the question takes on another value?
first without a plot and/or dimensional reference did not understand what you were referring to; I didn't seem to mention the design as much as the validity of the solution. what not being us rubberists (it is not the case of being engineers..) and not knowing circle and rubber in question (we know swx and "a little" of mechanics) we could not dream about it.

Anyway,
I'm sorry to disappoint you, but I think from that tire table you can't trace back to all the dimensions you need to draw the channel profile. there you have 3 measures we say "commercial" that are not enough for the design.
But are you sure the gum is that 43162? It seems to me that there is nothing to do with that circle of polite and with those vehicles, being this:http://www.racetires.com/shop/43162-road-racing-slicks-bias/Now,
or you want to build a circle from stockcars (but then you need to review some parameters by leaving that polytechnic study), or once again you will need to re-refer the question:biggrin: being aware that those project measures are not normally disclosed and do not find them on the catalogues (and here I think no one knows them).
the best thing would be to have a complete wheel to be detected.

I have to design a circle for that rubber that is lenticular like that of the polite and has diameter of 13". . .

I have to design a circle for that rubber that is lenticular like that of the polite and has diameter of 13". . .

but the rubber manufacturers, on specific request, do not release the specifications for the profile of the circle that will have to support that certain type of tyre?
It seems strange to me that they are such confidential info.
Alternatively, you scan a commercial circle profile for that tire. I made with a co-ordinated measuring machine, for the only profile that interests the tire, it costs you too little.

un lenticolare everything in carbon (on the falserigue of the example) for that rubber, for those cars, leaves me many doubts.. But you're the engineer. .
I imagine (hope) you know how a car circle is made (not necessarily as competition as your) and what functions it performs.
Regardless of material/sollecitation/resistance assessments, are you convinced that the "form" is suitable for purpose?
Maybe we should review the whole project.

for the material is all carbon, except the hub that will be titanium.
is not the first I see everything in carbon. lenticular is a test.

the "form" has been thought because in perspective of realization is very simple for those like us not have behind the redbull(team tugraz,austria).

Obviously I will check with appropriate software that goes well... but first I must draw this circle! !

from what I know the "tallonature" of the (of them, but I don't like it! :smile tires is standardized.
according to the tyre chosen the "tallonatura" should be identified.
Ask the tyre manufacturer the details, it should be able to give you the info on the profile of the rim channel.

It is precisely the lenticular solution "double" (closed by both sides, a disk like that of the example) that permeates me. car circles are made "bell", inside which there is place for disk and brake caliper.. Where did you plan on putting them? and for ventilation?

greetings
Marco:smile:

p.s. channels are also "standard". Starting from a "basic" circle you can try to dimensional it proportionally to the rubber you mount.

Well, I forgot to tell you that it's a single lenticular.

the reason is that of the brakes and ventilation of the same!

I asked the rubber manufacturer the details...I'm waiting!

Asked, looking for answers!

Thank you for the answer!

Well, I forgot to tell you that it's a single lenticular.

So you see that you have posted that example document that has nothing to do with your project? The only thing in common is the material.
the result is that you managed to "depistarci":biggrin:. and it took two pages of discussion to understand what you have to do.

at the end of the day, you can start from a common alloy circle (but also in steel printed for measurements..), pick up the channel and then make all the checks for the material.

If you have any problems in using swx ask here, you will see that the same language will be spoken. However that modeling is simple, you also find several video tutorials on youtube for rims and tires.

Here's the rim. . .

I have perplexity on the hub...
I didn't understand how the moment transmission happens with a single nut hub...
Are there any drag pins?

 

[Mike1967]

I have not understood: the state "designing" to then perform the piece, or
I've been modeling so much for...
No, because those questions you should have answers, I don't think
you adjust by hand, you have to have a maximum idea and then optimize
and improve the embryo project.
a view in section would have been more appreciated.
Anyway, good work.:smile:

ps: eliminates those improbable cut screws, you can not see in a mechanical piece!!
ps2: I think the hub is drowned in carbon... not hinged

We're designing it, and then we're doing it. . .

I have some perplexity. . .

what you call cutting screws are not screws, but drag pins...(you're right so drawn are just ugly,modified).
the power transmission should be input to the pins, while at the nut the task of blocking the circle in its right seat?

yes the hub will be drowned in carbon...even if I would prefer only the drowned plate and the hub screwed on the plate!

ps. There is an error in the design of the plate, tomorrow I correct!

Hello and thank you for the answer!
