Recumbent tadpole trike: Posts on Velomobilforum p.6

Hello sheng-fui,

I understand about translations since I must use one for German! I think I would miss so much without the translation as I found out the first time I looked at the forum with the machine translation. So German on Velomobilforum and American on my blog… Perhaps I will get it right the first time! ;D So on to leaning trikes.

I think I came up with a better geometry for the XYZ Leaning trike than what I presented but I am having real difficulty putting it into 2 dimensions. To solve that I am making a prototype in plywood. It will hopefully help me visualize. Maybe my prototype will let me take pictures that make sense instead of sketches and text descriptions. I believe what I have in mind is a bit like the Chike trike without suspension.

I think the Chike trikes are awesome! I think these trikes use a fairly common geometry. The nose rotates and with a modified wishbone they are supporting balance with shock control and springs. The shocks are also supporting full suspension as well. I see a cable going to the tilting mechanism from the handle bars as well as the brakes on each hub. I think there is some sort of control on the tilting mechanism being actuated by that cable. I think it is some sort of brake or friction mechanism. I bet there is a limiter in that center hub as to prevent over tilting too. All of this is just me guessing based on other research. The videos where amazing. Thanks for sharing neighbor!

Recumbent tadpole trike: Posts on Velomobileforum p.10

I have recently built about 4 possible versions of the tilting mechanism I have beem toying with in my very informal test stand. Here are some pictures of the one I think will work the best. This is pretty much like I think it will be on the actual trike. The orientation on the outer tilting assembly may change a bit but it will be very similar to this. The shocks that are visible should be the ones I use. The tilt arm on the center shaft will be very similar. At this point I have gotten the general outline of what I want to do sketched out in my mind. I have another bathroom to work up and a garage shop to work up before I get back to this little project. Time to get some of the things I put off during the winter done so I can get back to the trike. The things I have been figuring out lately have been the way to get my steering kingpins made and I think that by using a female heim joint and a longer bolt with a spacer to hold the extension of the...

Recumbent tadpole trike: Posts on Velomobilforum p.4 In response to Wolf and Hein, First Wolf's comment. What I am aware of is that there are quite a few tilters that do not use a monolithic steering system and have in fact decoupled the tilt in order to get the system to be stable. The brake application to the tilt is in fact an effort to stabilize the tilt. I am just before work here and have very little time to comment but I will try to cite examples later. Below is a general view of the Aileron tilting trike made by Wayne Soohoo it is pretty obvious wher the trike tilts. He controls the tilt by using a brake released with the steering handles. This is what I based my thoughts on for the theoretical spaceframe tilter. Instead of a remote release I think something like a direct brake would work as well. These data where gathered from http://jetrike.com/prior-art.html#Kurvenleger There are a quite a number of swing arm designs at this site. The above is the c...

Low cost loft bed

This is yet again a distraction from working on setting up the shop... Not an unappreciated one but still... I get to play with the GIMP drawing program to make a scratch design for a very cheap and minimal loft bed. This is designed for a twin long mattress or a twin normal length bed and a space for a built in desk underneath. The desk size and the rail size is not well defined but are sufficient for a build with little guessing. The head board and the back board have cauls glued in place to hold the desk top in place. The subpanels themselves are glued and screwed together in order to ensure solidity and rejection of racking. All subpanels are screwed together in place to make the full structure disassemblable to allow it to fit through doors . The following shows the general structure and the subpanel geometry. I will eventually get a general cut diagram up here and included is ...
