Working out the Roll-cage/body profile

Post by Frakentrike » Jan 03, 2018 8:47 pm

Working out the overall profile of the roll-cage/body. I was originally going to go for fibreglass/carbon fibre for complex 3 curves to the body but with my current level of expertise, equipment and time I'm now thinking I'll take the easy way out and stick with 2D curves and hopefully end up with something not too ugly or non-streamlined. The reality is that it has to be an open-sided body to allow for the tilting of suspension and the contra-tilting steering levers sticking out to the sides so putting effort into a more streamlined form is probably wasted effort!

I bent the first B-pillar roll-bar into shape and tack-welded it onto the trike after two earlier attempts to get the right compound curves that would clear the front wheels at maximum lock and when tilting as well as clear the heels of my feet when pedalling. Quite tricky.

I then managed to quite accurately mirror the second B-pillar on the other side after a bit of trial and error (yay!) and it's all looking good. Tomorrow I'll work on the rear roll bar and then the two tubes that will form the roof, windscreen A-pillars and nose.

At this rate I may manage to get most of the roll cage done before I run out of holidays. Just need to buy a new Tube-bender - I've bent the old one. I guess it doesn't like cromoly steel. Weak. :-)

Maybe the camera angles is playing tricks on me, but that seems to be a very tall cockpit?
Thought about a more discrete wind wrap? Here is Adams trike with wind wrap, he also uses a canopy sometimes.
Easy in/out and too.

Arcus and TryTrike

Post by Frakentrike » Jan 04, 2018 5:10 pm

Hi Macribs, the body is taller than velomobiles like Adam's as I'm aiming for a roofed design more like a combination of the Arcus:

...and the TryTrike:

Ahh now it makes sense. I thought you would leave the sides open due to suspension/tilting but I know see this will be full on fairing.

Roll Cage Tacked Together

Post by Frakentrike » Jan 08, 2018 7:26 am

The major components of the roll cage are now tacked together to check out the geometry and wheel and foot clearances. I’ll have to take a break for a couple of weeks now, but when I get back will fabricate the windscreen and body panels. Later I’ll work on the rear body.
