the_fettler Posted July 23, 2004 Report Posted July 23, 2004 Has anyone ever thuought about turning a buggy through 180deg? So the front has 2 wheels and the back has 1. Imagine how quick it would be to turn. Not sure how it would steer. Rack & pinion? (to complicated where lots of sand involved) A pivot in the middle of the axle? (suicide steering) Rear wheel steering? (like going backwards, only forwards). I'm not sure that it would be any better than current designs its just something thats been running through my head lately. Would it be I would be interested to hear what people think about it. I would be even more interested if someone has built one & has pics to share. Owch 1 Quote
Simon Bailey Posted July 23, 2004 Report Posted July 23, 2004 Thought about this myself, but after doing some working out, found that because the "Stability Triangle" was reversed, the pressure that would be applied to the rear wheel, would cause the buggy to be very tail happy. I did some modelling of designs, changing the wheelbase and moving the tow point forward, etc, etc, but the same effect was present. It'd be a fun project, maybe for a new trick buggy, using differential braking as the steering mechanism, keeping all 3 wheels locked in a longitundinal attitude. Quote
Ri chie Posted July 23, 2004 Report Posted July 23, 2004 well all you need to do is find some nice man with a four wheeled libre buggy chopp the front end off that and you have a steering system sorted, and then just find someone with a kitebike backend (theres a few of those around!) and then your sorted, ill be test pilot if you want!!!!!!! Ri chie ps, imagine the slides you could probably put in with it! the_fettler 1 Quote
cboshier Posted July 23, 2004 Report Posted July 23, 2004 the libre 2 wheel front bolts onto a standard libre back end I believe, so as Libre also do a kite bike conversion too you can even buy all the parts to do it ! (that is of courese if you don't like making things yourself) Oc1rob mentioned this in the kite bike thread just after wallop i seem to remember, I wonder if he's got anywhere with making one yet... I have to agree with buster though, as the back end would break too easily (unless you used a much wider wheel on the back or positioned it a long long way away.) and also reversing the triangle as he mentions will make it less stable too.

Simon Bailey Posted July 23, 2004 Report Posted July 23, 2004 Quick drawing. Keep all 3 wheels fixed (no steering), extend the front of the buggy forward to move the CoG and TP forwards. Feet apply pressure to simple friction brakes on the front wheels, creating differential steering. The CoG would need to be adjusted to stop the buggy pitching forward. Idle thoughts. Quote
Ri chie Posted July 23, 2004 Report Posted July 23, 2004 chris you seem to have a good blast at making everything else, so why dont you try this one, if you dont want to try it you can make it then ill try it out for you! Ill wait a minute for chris' better half to go before i drop him in more poo for wanting to try and make something else! Ri chie Quote
Simon Bailey Posted July 23, 2004 Report Posted July 23, 2004 Or a 4 wheel buggy that is 1 wheel at the front, 2 in the middle and 1 at the back. Connect the steering systems of the front forks and rear forks together (remmebering to invert the connections!), with the pilot sat "on" the centre axle. Quote
MIn Posted July 23, 2004 Report Posted July 23, 2004 I started to make 1 with rear wheel steering but quit because I realised that to ride out a sudden gust the back end needs to go up wind first. Quote
oc1rob Posted July 23, 2004 Report Posted July 23, 2004 Oc1rob mentioned this in the kite bike thread just after wallop i seem to remember, I wonder if he's got anywhere with making one yet... Still thinking!!! LOL My theory though was to use two wheels inline at the rear to increase the side slip resistance. I may get around to making a two wheel steer front at some point though! the_fettler 1 Quote
Simon Bailey Posted July 23, 2004 Report Posted July 23, 2004 HKN posted a link to a guys site (regarding "Micro Buggies"), but found this whilst there. http://209.206.250.72:8080/reverse.0001.html the_fettler 1 Quote
rasga Posted July 23, 2004 Report Posted July 23, 2004 Have seen a two wheel at fronn with steering mechanism, and one wheel aty back (on discs) Believed it belongs to mJohn, looks real nice, got no pictures of it though. That was a about a year ago, and then the original "flexifoil" creators first large buggy had two wheels at front and one at back. the_fettler 1 Quote
RAID Posted July 23, 2004 Report Posted July 23, 2004 Personally I would never need to reverse my buggy around so that there are two wheels at the front and one at the back, as I spend most of the time going backwards anyway. Quote

the_fettler Posted July 24, 2004 Author Report Posted July 24, 2004 Good work people. Im now thinking this might not be such a bad idea......I'll keep you posted Quote
the_fettler Posted July 24, 2004 Author Report Posted July 24, 2004 Buster boy posted this link http://209.206.250.72:8080/reverse.0001.html what i wanna know about, apart from the buggy is who do you talk to about getting sand thats that hard? Quote
cboshier Posted July 24, 2004 Report Posted July 24, 2004 oh it's still under consideration, as I've got the kite bike, it's just a matter of making a new front end, both the race buggy and the bike are interchangeable at the downtube rail interface so it's just a matter of making it (i've still got a mental picture of the libre version as a starting point) But next on the list (after the paraglider lightwind kite of course!) is the carbon trick buggy, after that I'll consider the 2 wheel front end..... Of course if anyone elsewants to make one before I get around to it, I'd be more than interested in the results Quote
Skyscraper Posted July 24, 2004 Report Posted July 24, 2004 Anyone ever tried this? Have a look at how kite surfers operate - the "pilot" faces the sail and moves sideways, and because the board is symmetrical they can reverse direction without turning. Why not have a buggy which can do the same? Simon Bailey 1 Quote
the_fettler Posted July 25, 2004 Author Report Posted July 25, 2004 A sideways one! Cool. But I think the two wheel front end with two inline rear wheels sounds like my fave. Still not sure about the brake steering. We have to work on that side of things............ Quote
HD462 Posted July 25, 2004 Report Posted July 25, 2004 Libre also has a 4 wheel buggy out too. It's not shown on the Libre website, but Pegasus has it on their site. It looks like it steers like the bogies (soapbox carts) we used to make as kids. 4 wheel buggy (click) Quote

Ri chie ps, imagine the slides you could probably put in with it! Thank you for the rep whoever you are, no a serious thank you! i got pos repped for the quoted post above! cant work out why, can anyone help! plus who are you my anonymous repper! Ri chie Quote
QUOTH Posted July 26, 2004 Report Posted July 26, 2004 for giving helpful advice??? why anonnymous? possibly a mistake. who knows Quote
Ri chie Posted July 26, 2004 Report Posted July 26, 2004 yeah i guess so! would make a change! almost tempted to go and talk to the lovely dt department at school and see if they will make one up for me! Ri chie Quote
the_fettler Posted July 26, 2004 Author Report Posted July 26, 2004 'twas me, im the phantom repper. I didnt deliberatly give you an anon one, it just happened. something interesting posted so i good rep'd you! You're right imagine the slides you could pull. Quote
QUOTH Posted July 26, 2004 Report Posted July 26, 2004 this what th erep system is all about :D :D Quote
Ri chie Posted July 26, 2004 Report Posted July 26, 2004 thank you mr fettler! doesnt appear that your a whore either so well happy about it! you got quite a website there mr fettler, having a nice look round! http://mark-tighe.co.uk/Content/Slide%20shows/Kites/html/14.htm where is this beach, probably not the best picture, but that bank looks fun to ride my buggy down! are you allowed to buggy there as there doesnt appear to be many pics of you buggying!
