Driven Bicycle wheels for Trikes/Quads

[rsisson]

I want to work on a powered Trike... but the plans call for MAKING you own wheel/hub/Axle things, ie building a hub on the end of a 3/4" shaft and then lacing a wheel to it...Uhm...NO !

Does anyone know how Rhoades and other Quad/trike manufactures attach/affix a semi-standard bicycle wheel to their driving axles?[

The picture below is what the plans call for you to MAKE... the standard hub is used for spacing and alignment...
I really don't want to do it that way...

I use a 17 mm shaft on my trikes and the hubs to match with 12 guage spokes. so far ive been 650 miles with no wheel problems at 400 lbs plus. the reason is i just could no find bike rims that take the 3/4 id bearings, 5/8 and 17 mm is the best i could find that looks like bicycle wheels.. the hub is tied to the drive axle by a plate that is welded to axle and has three studs the protrude into hub.. If you have a source for 3/4 shat hubs id sure like to know it
thanks again

Easiest way to make a trike hub powered wheel connection is probably like this...
Do it right and each side could have it's own suspension and by not using a center axel across both wheels you have no need of a differential. If you still need to pedal then you can have a comman axel in front of the wheels and a chain goes back to the wheels on each side.

I don't know what kind of trike you want, but here is how they do it on my shwinn. the frame is in two parts. The front part is basicly a cruiser frame with two sets of dropouts. The chain goes to a hub with two sprockets a band brake and a freewheel. The second sprocket has a second chain that drives a simple sprocket on the rear section of frame. All the rear section does is drive one wheel so no need for a differential. You can see a good pic of all this at the wallmart website. Look for Schwinn meridia trike. Maybe looking at this can help you get some ideas. The bike is pretty cheap, so maybe it will be worth it just for the parts, like the rear axle and wheels. Slap a used rear wheel on the rest of the bike and sell it.

"All the rear sprocket does it drive one wheel...."

Ok, how is it done, I can't quite see how it is sone in your pictures..

On SOME there is a short jack shaft that goes from the lineup of the drive, shifts it right enough to line up with the drive sprocket on a standard wheel...that works if you are a SOLO..

However...what I am looking for is how to have a LIVE AXLE (found the name). Miami Sun uses a special hub that has holes in it that connect with the axel protrusion... and a nut on the axle keeps everything snug, but loose enought to allow the bearings to float... the non-driven side just has the axel with no pins to connect it to the axle....

Unfortunaetly, I think it is a propietary size/shape axle connection thingy...

I didn't really pay attention to this detail on 3wheeler's pedicab. They obviously have a way to do it. They were using 48 spoke wheels. You might checkout the URL in the picture.

Yeah that is it, but in that pic it dont look much like mine except I built a box under the basket too. Lot a cool mods. The dead axle is round and the live one is keyed so that hub is D shaped. Im not sure if both axles turn or just the keyed one. In any case if he dead side turns, it can't drive the hub, it just spins on bearings. It gets interesting on two wheel corners since on one side you lose your drive if just peadling.

The pedicab above has a real differential in the middle of the axle and both wheels are driven.

Those parts at choppers r us are pretty much the same as the stuff on my schwinn. It only drives one wheel, but it's easy to put a motor and sprocket on the back chain. That is a very cool site. I need to learn to use my welder.

Above there was a question about Rhoade bikes, they don't use bicycle wheels. They use trailer wheels, yuk.
