Hi. Here's my big and heavy northern norwegian wooden velomobile. I think it weighs between 65 and 70 kg. The 250 W (nominal ;) ) assist motor makes it feel lighter. I made it to replace my car on local errands.

I have started designing a new velo which will be faster.

nice build. what type plywood did you use?

Lynxman
06-13-2016, 05:10 PM
I used pine plywood for all the woodwork. 4mm and 9mm sheets were thinned down or doubled up to add strength or remove weight, as I saw fit using the TLAR-method. :)

I'm slapping some paint on the velo this weekend. One more coat and it's ready. Takes a long time to dry in the cold though.

Have you considered solar panels? The design seems almost intended do carry solar panels on top!

Lynxman
06-22-2016, 04:48 PM
Yes, I did have solar panels in mind when I made the plans, but I don't need them. Would still be cool to have them in case I ride far. The plans evolved away from solar panels, so the dimensions of aren't optimal for solar panels any more.

I received a new shock to test in the front today. Much better than the old one, so I ordered another one for the other side. The old ones are friction shocks, and I had hoped they would loosen up with use, but the dampening is still as stiff as a block of wood. The new ones are much more plush. The new oil shock is on the right.

Here's a shot of my velomobile from today. It got a lot of positive attention from kids and adults. Some kids wanted to know where I had bought it.

The new shock looks neater and possibly lighter too.

I ordered a 100 W solar panel now that is the same size as the rear door. It'll be interesting to experiment with it. I think I will make a new rear door using the panel as the top sheet to save weight, instead of sticking the panel on top of the old door.

We don't have as much sun here as Germany, but the lower temperatures, and snow covered ground for most of the year are beneficial to the solar panel efficiency, according to research. The rear door on my velo is quite flat, however, so it won't be able to take advantage of much snow reflection, but it will be interesting to run measurements.

Solar panel installed. 100 W panel, but I don't have a regulator to wire it up yet.

Nice!
For me, with approx half an hour to work, that size of panel and a sunny parking spot during the day would make the velomobile practically independent from electrical outlets!
As for wiring, the Velove cargo velomobile uses two batteries: One for driving while the other one undergoes charging from the solar panel.
This is a pre-series solution but very functional. Read more at http://velove.se!

I have started preparing for the pneumatic leaning system. I made a two piece pulley to mount on the end of the steering axle, which will let me index the steering with a belt down to a potentiometer. I use the same belts that drive my 3D Printers. The belt is open ended so can be wrapped around without disconnecting everything.

I also brazed some piano wire to the ends of the mirror posts so that I can adjust the pitch of the mirrors from inside. I will 3D print some nicer handles to slip over the piano wire.

Here's the potentiometer mount. A ball bearing supports the shaft end to reduce the radial load on the potentiometer.

Beautiful machine. I've always been interested in Velo's, but worried the drivers here will just see me as a slow car, and get aggressive.

Morning gir. As the Place of Residence is Norway I assume the night light is due to twenty-four hour day as it is northern hemisphere summer now.
But I am impressed with the build. I though being in England get a day and a night result.

I'm far north from Bergen, at 69 north, which is why we have 24 hour daylight here in the summer, and no sun at all in december and january.

It is obvious that you need more gears than I do in my flatlands!

Im curious about the solar panel, have you wired it up and if so; How?

//hp

Lynxman
07-24-2016, 06:41 AM
I wired the panel up with this regulator: http://www.ebay.com/itm/271833256005

I measured the efficiency of the regulator to 88% at 100 W. It also blocks any current from flowing in reverse, to the panel. The highest power that the solar panel has charged with so far is 50 W. It recharged my battery twice after riding. I usually stop charging at 41 V instead of 42 V to make the battery last longer, and set the regulator to 41 V. Yesterday it charged 180 Wh from morning to 13:00, and stopped when the battery was charged. It works well but I wish the panel was more efficient when it's not sunny.

Thanks for the link! Do you upon this use a charging circuit of some kind or do you find this one capable of controlling the whole charging business? (Me beeing a bit nervous about charging...)

This works fine on its own. A charger is just a power supply with a limited maximum current and voltage. The BMS takes care of balance monitoring, and will temporarily cut the charging current to correct balance if necessary, but my pack stays in balance.

Very Nice in Model design. Does this design incorporate a lift up pod for entry to vehicle? Also will this vehicle have motor-assist?

The whole copper-colored canopy will tilt forward for entry. I hope I can built it light enough to not need motor-assist.

I would like to use a custom rear derailleur without pulleys, and a separate larger tensioner pulley, to reduce the chain friction.

Here's a printed test version of the differential. It will have a screw on 11-36 ten speed cassette. The gears are straight cut angle grinder spare gears. I will make it from aluminum.

Impressive CAD-work and 3D printing! Feeling a bit off here, but are we speaking front wheel drive here?(Maybe I missed something)

Do you get sheet cutouts, eg for plywood sheets, for from the cad? If so, what software do you use?

Thanks for feedback on charging!

Yes, front wheel drive. It will eliminate all the guide pulleys and guide tubes, as well as let me use a short chain.

For ready made diffs look to Samagaga: http://www.samagaga.com/Category.aspx?Category=DG72

They look well made and are reasonably priced. About $100 for one unit according to a member in my thread on Endless-sphere.

This thing has been discussed at quite a lenght here on this forum before...
including comparisons between freewheel 2WD ve differerential (and why diff without limitedf slip, might not be as good as you are hoping for)

Thanks for the reply. I have tried to email them but just get an error message. The project I'm planning on using them on is a quadcycle which I think (hope) they would be adequate for.

Having the brake mounted to the diff is a bad idea. Also, the worry about one wheel slipping is exaggerated, because it takes twice the torque to that wheel to spin it when the other is not spinning. It's not like I will drive with one wheel on ice and the other on asphalt. I was going to make a freewheel diff, but decided against it because it will put much higher loads on the universal joints and telescope shafts. More than twice the load actually since it's the inside tire that drives.

I believe the freewheel diff' has proven itself to be beneficial in rear wheel trikes that are lightly loaded on the rear & tend to lose traction riding uphill.

On a front wheel drive tadpole trike with much of the riders weight over the front wheels I'm sure that wheel slip will be less of a problem.

I can easily make a freewheel diff instead if it turns out to not work well. :)
