Hello Hein, Titan Wolf, trike like (Martin?) and Stephan (shs2_de) It has been a couple of weeks since I was able to remark on what I have been doing with the idea of a tilting space frame trike and I have some things to share. I have built another new prototype of a tilting mechanism and have already come up with a new version. Interestingly enough my newest designs bears a great resemblance to what Stephan (shs2_de) worked on with his suspension system at the beginning of this forum file. It may be interesting to Stephan and others to see a modification of that suspension system. I have also spent a considerable time with my husband and a friend remodeling our 2 bathrooms as well as working overtime… Sigh real life… enough said on that subject. Before I much go on I want to address a couple of comments from Wolf. I read your comment on obstacles in the road and thought about that in terms of tilting and locking the tilt mechanism. First I think that a tilting trike (1 st te

Shop Workbench: Internet amalgam The lift and cranks are just visible and the vises are obvious but look at that top! I mentioned that I was finishing a shop workbench and now finally I am getting close to rounding out this project. Not sure I am ever really finished with a project but I will soon cease to work on this one because I would have to start over to make a new one if I did! I will tell you a bit about the workbench, show you the basic plans, and then tell you what I would change. This workbench has a Paulk workbench top that has been modified to use in a shop as a primary workbench. You can find his plans at  http://stores.modularmarket.com/paulk_homes/  .  I will no doubt show you pictures of what I built but I will not gift you the plans. Hey Mr. Paulk originated the thing so go buy the plans if you want to make one. I will try to give you enough hints to help you make it successfully. The bench has been modified by adding two Moxon style wood vises and two more

Recumbent tadpole trike: Posts on velomobilforum p.7 Hello! I have been doing some fast prototyping in plywood. I glued up a strip of 3/4" plywood and  1/4" plywood (they are actually metric ply close to those measurements) to get a small sheet of 1" thick plywood. So I then cut this to made some 1" square plywood dowels about 8 foot long.  From these dowels , some wood screws, and a couple of bolts I put together a proof of concept tilting trike frame. I want to play with it a bit and will buy more hardware to hopefully put on some wheels.  Nothing I built is usable for riding. This is literally just a full scale model and a poor one at that. Mostly I want to see the full size geometry and how the machine functions. So here are my pictures from shortly after the sun was up so forgive the shadows. Now tilting Right Now Tilting  Left Now a couple of close ups of the middle. I will post more as I bui

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 wi

Recumbent tadpole trike: Posts on Velomobilforum p.5 Hello Titan Wolf, Hein, and sheng fui, I think perhaps I will post the American version of this on my blog at https://dichotomyone.blogspot.com/ and post the German one here for ease of use by the mostly German viewers here at the Velomobilforum. It should be better for anyone who prefers German and the American version will only be a click away. Sheng fui will have to let me know if the translation is better with deepl than it is with google translate since that is what I last used for translation. Hein I think you had a point about lash. Without self balancing geometry that is exactly what would happen without a control system for the tilt. The comments below are also for you and anyone else that may be interested. Wolf I have been looking around and thinking about your note and have a couple of more comments. I am not sure I completely understand what you where getting at but I took a couple of things fo

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 closes

This is my third post and response round from the German Velomobilforum and can be found here or at https://www.velomobilforum.de/forum/index.php?threads/eigenbau-xyz-spaceframe-vehicle.33109/page-24 In response to Wolf and Hein, First Wolf's comment. I think that working the tilting into the Akerman steering plate found in below seat steering is an excellent idea. It would incorporate the tilting into the steering in a fixed configuration and allow the user to completely control the action using a "normal" steering action. 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. Hein, I admit I did not think about a lashing effect from releasing the tilt

First post to the Velomobilforum is about a potential tilting mechanism for the trike that a friend of mine and I imagined while chatting at work. See below. Hello everyone, first as can be seen I do not speak German. So introductions, my name is Ceeann and my forum name is ceeone. I am 56 ,female, and married. I seem to be in a minority for self builders but I have wanted to build a trike for some time and I have become enthused with the idea of building the spaceframe trike along the lines of the n55. From what I can tell this is THE forum for builders of the n55 type trike. As I have been absorbing the design for the n55 and looking at all the upgrades and modification all of the members here have been posting I have had a brain storm or two myself. First I would like to repost a build picture that Trikelike posted on 20.01.2017 I really liked this design for the cross member of the trike due to the inherent stability this equilateral trapezoid should show for fram
