Alloy rims: Questions!
I visited your website... WOW! What a WONDERFUL re-build! Looks like NEW!!!
Thanks for sharing about exchanging the wire rims for alloy rims.
I'm planning to build a high mileage hybrid reverse trike using a Vulcan500 as the donor for engine and rear rim.
I "just" posted my introduction in the new members forum and posted some images of my design with info in my intro thread: "Using a vulcan500 for a reverse trike".
After tons of research (LOTS more still to do!), I've decided on a post 1996 vulcan 500 and wanted to change to alloy rims.
I've read elsewhere that special spacer modifications were needed to do this? Was this yur case too?
Did the brake assembly switch out without modifications?
Did the switch from belt to chain rear sprocket go as easily? (Simple unbolt, replace and bolt new chain sprocket in?)
A final question involves "lateral stress" strength:
On a motorcycle, stress on swing arm and wheel is always perpendicular to the axle (straight down)... On this reverse trike, the rear swing arm and wheel will not tilt, so the stresses incurred will be lateral (side to side rather than up and down). Vehicle weight will be between 1,000 and 1,500 pounds, with the rear wheel supporting 1/3 of that weight (roughly 333lbs to 500lbs). I have no idea what the "G-forces" will be, but the intended use is for "cruising" and grocery runs, NOT for racing.
I've been over-thinking most of the systems I've been collecting (As a prototype developer, I always approach projects with "What could go wrong?" and then design to avoid that.
My worst nightmare would be lateral forces that would fold the rim up like a taco, bending at the axle... What do you think?
Also, Since the tire will never tilt, I'd like to find a flat tread (like a car tire) with a wide footprint that will fit this rim.
My concerns are:
If the tire reaches out far enough (side to side), there will be a conflict with the chain sprocket and the brake lever.
The brake lever can be overcome through machining.
Can the rear chain sprocket be pushed out away from the center of the hub, so the chain does not come near the rear, wider tire?
Note: because of the lateral/torsional forces that will be incurred, I will be building a rear swing arm from scratch, so tire/chain clearance will not be an issue.
Thank you so much!
