This delta trike velo also didn't turn out as fast as well as creator hoped to: Not being able sprit at 40 kmh is strange for a fully faired hpv with 'proper' aerodynamics (and your main shells seems VERY slippery), but when outboard wheels come into equation things get nasty.
did you measure how much interference drag is generated is by outboard wheels?įrankly, they don't seem well-positioned at all and likely prevent pretty much any pressure recovery as well - you want them either trailing behind the tail or faired into the shell - I did CFD for a similar concept and outboard wheels at pretty much that location generate 1.5 more drag than a MUCH wider shell that has wheels 'faired in'. Well, turns out I was spot on in my posts above (unfortunately).Īlso, you said you did work on the fairing shape. Ok l added another ? for you at post above with youtube ? If you are good at riding 2-wheel recumbents (including the kervelo) you can probably do it. So calliper behind seat has mild tension? great vid. When i skip to 4:08 and watch a lil’ Wim tilts it back an forth and it looks like it behaves with some tension at vertical and it does not just fall over. Thanks much: so with lock off and the steering to also help upright you its not hard to go back to center? The kervelo wasnt to easy to start riding either, using way different muscles than velomobiel. This is exact method used for velotilt wheel pants, all 3 of em. Part in primer out of mold this morning.Īmateur youtube for explanations. Use your 1955 fender skirt imagination: trim and fit an something. The steering is very heavy (designed for tilting mode operation), and if you would turn a corner there is a risk of bending the tilt mechanism or falling the bike over. Both the steering system and tilt-lock are not made for driving while locked. Riding around with the tilt-lock on, though technically possible, is very unpleasant and possibly dangerous. Instead of putting your leg out like a regular bike, you lock the tilt-lock and the bike stays upright on 3 wheels while stopped. The only reason it has 3 wheels and a tilt-lock is so that you can start/stop without putting your leg out (which you can not do inside a fairing).
#HOPEFULLY TILTING ELECTRIC TRIKE DRIVER#
The driver has to keep it upright by steering just like on a 2-wheeler (it is not easy). It drives (and is designed to operate) like a 2-wheeler (free to fall side to side, leaning in corners). You have to understand that velotilt does not drive like a trike. I am a sturmey archer drum brake fan.Ĭan u explain tilt lock system in a simple way sitting in velotilt turning corner.? Think sturmey archer drum brakes like l installed on my rear quattrovelo hardware. Guy while ago said Belgium requires 2 brakes. This is better than a catrike or ice trike, ride all year here. I live at ft bragg nc 5 miles in fayetteville. The velotilt is easy entrance and exit for out soldiers, people with knee replacements, back problems, etc. Pinion has e-motor sitting on top of their 18 sp gearbox l wish they would finish. Gates is the north American dealer for pinion. L work with gates corporation in denver colorado, gates carbon belts. I have bladder molds l have made and have oven for macrolon and other plastics. Ive had great machinist and welder friends for 35 years of flying my airplanes, 92’ i switched to experimental planes. My parts come out primered, & mavcoat release agent is just incredible. Ive met some tilt people over the years and in europe. Its one hot place here, the sandhills of n.
But here a summer top with hood like waw that folds in bag behind seat like waw does. It has summer and winter top, thats great. Go to velomobile section and read my thread and this one. Nothing wrong with carbon foam but l like carbon innegra. You said it: just keep on educating the velotilt. Also the front wheel fell of after 100m (indicative of the internal structures quality).
#HOPEFULLY TILTING ELECTRIC TRIKE FULL#
When i rode it i struggled to exceed 40km/h in full sprint. The internal structure however is underdevelopped and way too heavy. The fairing and carbon monocoque is good and very light, and the tilt lock concept is a stroke of genius (and the prototype tilt mechanism with lock works reasonably well).
The original project leader never recognised how much engineering effort is required to build a proper velombile, and was not prepared to do what was needed. My ophinion: The concept can work, but will take a significant engineering effort to develop into a successful vehicle. I did most of the design work (the outer shape is purely my design), so I could probably answer specific questions that anyone has (to be honest i have not read the whole thread above this).
