rim flange design/dimensions/specifications in correlation with balance weights
rim flange design/dimensions/specifications in correlation with balance weights
(OP)
Hi,
Who knows where I can find specs (dimensions and measurments) of the different rim flange designs?
Is there a correlation between the different rim flange types and the different types of balance weights?
Thank you in advance!
Alex

RE: rim flange design/dimensions/specifications in correlation with balance weights
So to cut a long story short we shadowgraphed a bunch of wheel weights, and then developed a rim flange profile that progressively opened the clip (they yield, so don't rely on them closing again).
Things may have improved in the last 20 years, I doubt it.

So this would mean that I could "copy" the J(ISO) contour (or JJ etc....) and for most balance weights this would mean they fit on the countour's flange?

I already found out about SAE J1986, but unless you buy the PDF you can't get any info on this topic. Plus the fact that I don't know if J1986 holds the info which Im looking for!
Thank anyway!

So, having a TRA yearbook will do you no good if your goal is design a wheel so that clip on weights fit.
I do know there is a correlation between the contour of the outside of the rim flange (the part TRA doesn't specify) and the shape of the clip on weights. There is a code for the weight that corresponds to the contour of the weight and there are charts listing the manufacturer of the vehicle vs the weight code. Obviously that only works for the OEM wheel.
I did a quick look and I see that Myers Tire Supply has a gauge that can be used to select the right weight code of the wheel.
On further looking, I see where SAE has a handbook for wheel standards and included in that is balance weight and rim flange design. I suggest you start there.
RE: rim flange design/dimensions/specifications in correlation with balance weights
Thanks for your insight on the topic. The SAE handbook you were referring to is the SAE J1986.
I find it very odd that one can find every detail and aspect of a rim, like dimensions and specifications of the hub and valveholes, but nothing on flanges.
I really would like to see some detailed profile/contour of a balance weight.
Anyway...it seems that the balance weight industry does not want their information out in the open.
RE: rim flange design/dimensions/specifications in correlation with balance weights
Obviously, I cannot simply post the SAE spec on here but I can tell you that it does contain the recommended detailed width, thickness, radius, etc of some flange types (P, C, T & MC, as mentioned in my previous posts) as well as the recommended wheel weight dimensions (gap, radius, etc).
Alternatively, if you want to PM me I could open a channel of communication with my colleagues and see if you would like to work directly with them to find out the proper dimension for the wheel weight flange.
RE: rim flange design/dimensions/specifications in correlation with balance weights
If I could get detailed info on width, lenght, thickness, radius etc.. of the most common wheel flange types, I already would be very very happy.
Got no idea how to PM you here, So here's my email: alexkitzen@gmail.com
Thank you in advance!

Alex
Just being curious: what will be your new job?
RE: rim flange design/dimensions/specifications in correlation with balance weights
My new job will be for a toy manufacturer, construction bricks.
