I‘m building a tricycle that will have rear-wheel traction, fed to the wheels via an axle.Planning to remove the bearing parts, yet the wheel axle will still be smooth on the inside. How do I get the axle to bite in order for the wheels to rotate with no loss of energy?Thanks
there are loads. i just got one from EMERY surfboards, depends where you are from/ im from lennox, near byron bay. around there is Free flight, local motion and loads more. just ask local surfers they'll know
You really can't get a board made of only fiberglass and foam you need a resin to hold it all together. That is why they use epoxy, but there are other resins out there. like polyester and vinylester resins, but I've only seen those two resins used in skimboards.
Your question shows one reason why tadpole trikes are more popular than delta trikes - efficiency of the transmission without custom drive-train parts. Then all you have to worry about is Ackerman steering. Plus, tads are less likely to tip in a hard corner.
First, keep in mind that only ONE wheel should have power to it or when you turn the outside wheel will skid around and might make you lose control. If you are planning to use a standard wheel for the drive wheel, take the bearings out then tighten the cones right into the hub body. REALLY tight. Add a locknut on both ends of the axle. The next question is, how are you planning to drive that wheel without a LONG axle that extends to the chainline? Were it me doing this I would use a piece of 3/4 diameter (19mm) heavy gauge tubing and have it welded to the hub, then work out a differential that houses the bearings at both ends. Unless you are very good at this type of thing I am afraid you'll discover that it would be cheaper to buy a ready-made trike. I just thought of something that would be really cool. how about modelling a big bike after a kiddies bike- with pedals on the front wheel? That would solve all your problems- just make crank arms that'll fit the front wheel and also act as the axle.
