The Ziggy Build

[ziggy951]

I figured I would start my own thread about my build rather than cluttering up the other threads.

I am working on creating a basic frame shape that can be used as a basis for any project.

My design will be a 1+1 seating configuration with less room in the back seat than the front. The internal space in the cockpit is estimated at a maximum height of 46 inches, maximum width of 30 inches and maximum length of 95 inches. 50" for the driver and 40" for the passenger.

As far as wheel configuration goes, I hope to have a tilting 1F2R design but I am leaving space in the front or rear for pretty much any type of configuration that is wanted, provided all propulsion takes place in the rear. There just wont be enough room up front until in wheel motors are a realistic possibility.

Thats really it as far as the basic design goes. Things like doors, windows, AC, and radio are all possible in my design but placement will be up to whoever actually uses it for a real build.

I will post pics and update dimensions as my design moves forward.

Zig...Sounds really good. I wish you luck in the build, and hope we can glean a few things from your work on our own project.

By the way, are you going to be using the same steering system as the Carver?

[ziggy951]

For this project I was originally just going to share a frame design so people could use it for ideas. Steering, doors, powerplant etc would all be choices exclusive from my design.

That being said I would personally like to use a steering system that is mechanical, or at least mostly mechanical. That way if something isnt working right I can just make a correction rather than go through the process of contacting a non-local company for a fix or looking through code for an error.

I also dont know if I can get a hold of a Carver system, or even mimic one on my own. Purchasing one outright would be quite expensive I would imagine.

Another issue with the Carver system is that I am very unfamiliar with it and without some serious help it would take me a long while to figure everything out.

Personal choice for a powerplant will probably be some type of genset setup. That way I can get good power and still have some fuel economy. But then there is always the posibility of throwing a Hayabusa engine in the back :)

For a body I will probably copy the Aussie university method that was listed in the other thread. Pretty straight forward and it will work well with my frame. This way I can make the main tube fram for safety and have the lightweight stuff molded around it for looks.

This is a pic I took to show how my setup sizes up to the Pursu. The black body is the Pursu and the people, brown and red parts are part of my build. The pink line at the bottom is just a measurement tool. It is 50" long by 30" wide. This picture is to scale.

I sat in a race seat and measured the distances of length, height, and width of myself and made the human form in the pics match those measurements. So the people in these pics have "to scale" measurements of someone that is 6'4". I am only 185lbs though so the 30" width measurement may be a bit tight for some folks.

First rough of my body style. Next I will rebuild the frame to fit such a body.

Quick update on the frame. I think I went a bit overboard with the bends so I may make some adjustments. The middle area is intentionally left open for personal configuration, seats, etc.

[ziggy951]

Made some adjustments to the frame. Reconfigured the base and added a V shaped bottom, then strengthened the middle. I also added a rough of a frame for the engine pod area in the rear. Total Length from the nose to the end of the pod is now 153 inches.

Ziggy,
Looking super! Personally, I would like to see the bar by the drivers shoulder come up higher for roll over protection. Same with the bar above the dash. In formula cars you draw a line between those two points and the drivers helmet should be at least 2" below that to allow for some belt stretch in roll overs.

[ziggy951]

I am having trouble placing those two bars in fact. If its too high it blocks the view for the passenger. If its too low it doesnt provide protection. I think I am going to lift it up and over in an arc rather than a straight line. Then put a straight bar behind the driver seat, maybe crossed bars, not sure yet. Because of the V bottom the 2" distance shouldnt be a problem. Now the seats are a bit lower into the chassis. This should also help a bit with a lower center of gravity.

I like the arc idea. I think the single bar behind the driver seat provides an excellect place for attachment of the drivers harness.

Again, really nice work!

ziggy, you might want to rename this thread a little bit to avoid confusion as I'm also working on a trike design and plan to show it here. Don't worry, my design is 2F1R with tilting front wheels so we are not in a direct competition:)

[Miracleman89]

I know I have said this before but, " God, We have some talented people in our club!"

Nice work Ziggy! And WarpedOne I look forward to seeing your project!

[Derwin]

ziggy, you might want to rename this thread a little bit to avoid confusion as I'm also working on a trike design and plan to show it here.

I'll go now and rename it "The Ziggy Build".

By the way....Great graphics, zig! Looking forward to this progressing, and seeing pictures of the real thing.

Hopefully, we'll be seeing the "real thing" from Persu soon. du:n:n:o(

I am also making a space frame version of the V1 for all the purists out there. Should be done by the end of the day.

I am debating a 2f1r design as well. I just cant get my head around the control mechanism that mimics the VV design. I also like the idea of 2f1r for braking.

As promised. Keep in mind that this is a tube frame for the Pursu as we know it, not the Carver.

Amazing Ziggy, looks great. A bit 'cramped' in the rear, but with the proper driver's seat construction, and perhaps the 'option' to place the legs along side the driver (if needed) it would work very well for my needs.
With the current frame layout, it would even allow for the 1.5 doors on the side for easier access to the rear. (I'm sure 'SteamBoatWilly' will be happy)

[ziggy951]

The picture in post #15 is just a tube frame version of the Pursu, not the frame I'll eventually use for my design. Just thought it would be a neat exercise for everyone to see. If anyone wants the 3D file I can send it to them for reference. For me, its easier than using the IGES file.

[wireman]

I like it as well, Zig. I'm unsure, though, of the purpose of the framework beyond the driver's feet. My suggestion would be to extend the frame to just beyond the limit of the driver's toe when he is pedal-to-metal, and begin the front wheel assembly from that point. Then you can extend the pod at the rear to make more room for powertrain/batt's/etc..., without changeing your overall length. I have always thought that one of the failings of the Persu design was that they had to pile up a lot of stuff in that tiny power pod, worrying too much (unecessarily) about the OL.

[MikeB]

I like the arc idea. I think the single bar behind the driver seat provides an excellect place for attachment of the drivers harness.

I think the single bar behind the driver's seat is a potential safety risk: in case of a crash, a passenger in the rear seat could smash their face against a solid bar rather than a softer seat-back. If you do keep the bar there, then some sort of padding would seem to be mandatory.

[ziggy951]

The bar would be mid way down the seat so the passenger would still hit their face on the seat, provided they chose to NOT use their 5pt harness. With a harness they shouldnt move enough to hit anything in front of them.

Great work Ziggy, it's really looking good.

[Gunner]

Way to go Zig, you're doing a great job! Your frame allows for a little more room for cargo too. Cool

[Derwin]

Ziggy, have you made anymore progress with your build?

I have actually decided to move forward with a build of my own, and want it to be a 1F 2R design. Yours seems to fit the bill, but do you know exactly how to proceed? In other words, do you have the plans and specs all laid out on how you are going to put this all together?

I think building a one-off vehicle can be much easier for us to do, then for Persu or any other company that needs to make it for mass production.

I'm excited to see what you come up with.

Derwin

[ziggy951]

Working on fittment of suspension and engine. Also debating whether or not to plan out an EV version. As always the energy storage seems to be the high cost tradoff for the EV so I may jus scrap it and build out a modular area in the rear for propulsion.

I have also been reading up on patents that use tilting mechanisms. Mostly in the drawing stages of all of the nitty gritty stuff. Also been working a lot lately, gotta meet those deadlines!

Should have an update sometime next week.
