First 3D of Lamoto2 Center Hub Steering is online

February 16, 2011 – 12:54 am

Hi everybody!

I’ve done a basic geometry of Lamoto2 Hub Centre Steering bike in 3D

It will be updated with your help.

Front wheel travel is 120mm
Anti-dive equivalent to 12º fork
There can be mistakes, so please report everything you see.
60º laying is no tested, neither 15º steering
Wher can we put the front suspension??
There’s a lot to do!

find everithing in the FTP de www.lamoto2.es under: Archivos 3d/Geometría 20110216 (register first)

Regards!

Edward Hartel system and proposal for Hub Centre Steering Moto2

January 24, 2011 – 10:32 pm

 


Due to the www.lamoto2.es project I have received some interesting mails with bikes and suspension systems. I´ll try to publish them.

Here is the first one:  

EDWARD SAID:
I have a mixed background between cars and motorcycles having worked in motor racing (european formula car racing and 500 cc GP motorcycle racing) for some 10 years…
In my spare time I am building a new motorcycle concept of which the rear suspension is finished, which is currently employed in a Suzuki 1200 Bandit for testing, but it will be part of a totally new motorcycle concept. The new bike with fully adjustable single sided front and rear suspension will be powered by a Norton rotary engine coupled to a CVT transmission.
  
The reason why I started my project was that I firmly believe that there is room to improve on the current telescopic front fork design as it has some major design flaws which can not be changed, but just slightly improved. Bearing this in mind and my admiration for the alternative suspension designs dating back to the Ner a Car bike up to the latest effort by James Parker I decided I needed to design my own bike. The thing I wanted to change the most was the fact that I want a split-up between the four actions/forces: steering, braking, shock absorber and spring. In this way I could give a different ratio to the spring and to the shock absorber and seperate the steering, shock and spring from the braking forces as it does with the telescopic front fork.
 
At the same time with the multi link suspension units one could also implement anti-diving and anti-squat in a more controllable way then possible with the telescopic fork and the classic swingarm. However what was/is missing in all these alternative front-end designs is that this should also go hand in hand with a new front tyre design, capable of handling the different loading and grip levels. All these bikes were relying on tyres designed for telescopic front forks thereby undermining the potential of the alternative design.
 
At the moment I am still working on the front end which hopefully should see the living day lights this year (I have the front axle, wheel is being modified to install a rim mounted brake rotor, shock absorber, steering controls). Why do I say this year, because I have been working on this bike for quite a number of years now, but with limited funding (I am paying for all the work/parts myself) and do all the design work in the late hours of the day, after I finish my day time job and my familiar duties. Unfortunatelly there is very little room in Holland for these kind of projects.
 
I have enclosed a series of pictures on the rear suspension, which I have been test riding (many hundreds of kilometers) during the summer of 2010 on various roads to be able to find out if the road holding and durability is at least equivalent to the standard swing arm. Although the set-up is a bit of a compromise as I wanted to obtain the original lay-out as well in order to test back to back with the Suzuki swing arm, and not change the entire frame, the outcome of the testing was very good in terms of feedback and stability.  

  

  

Obviously Edward it’s a master of motorcycles and I hope he will find a bit of time to spend in the Moto2.
I think it’s a very interesting bike. What do you think about it? 

He also sent me a very interesting paper and some pictures of a bike I’ll publish in other post.  

Thanks a lot Edward!

Project Center-Hub-Steering LaMoto2 starts!

December 15, 2010 – 11:36 pm

Finally I can present the LAMOTO2 project!

First Center-Hub-Steering Moto2

If you ever wanted to participate in the engineering and design of a real race bike, the time has come.

Beltrance.com, Demonstener and LA MOTO magazine start a joint venture. We have sponsors, good ideas and a lot of work to do!

On the Spanish kiosk you can find LA MOTO magazine of this month and in the web www.lamoto2.es the complete information about this amazing project.
Unfortunately, for the time being the web is only in Spanish but this site will be the English loud-speaker of this project.
So I´ll publish the most relevant information and the key papers and of course I´ll try to publish the best ideas you propose.

Thanks for being there and remember we need your help!

Electric and Human Powered Aircrafts

November 17, 2010 – 11:20 pm

This morning I was having breakfast with my coordinator when he gave me the EADS magazine, called FORUM. It was full of interesting news. Well, I don’t like to advertise any company but this paper was really interesting…

 Continuing with electric vehicles, I want to talk about the CRI-CRI (not a beautiful name) The CRI-CRI is the first-ever four-engined all-electric aerobatic plane, and it flights! This minimal plane reaches 110 km\h among other incredible performances.

 Here is the original post.

 Take a look also to this: Electric planes (Wikipedia)

 But if you keep amazed by an electric aircraft maybe you don’t know about Human Powered Vehicles… There are planes that flight just pedalling. Like my loved Daedalus made by the MIT. And there are also attempts to human powered helicopters… and I prize if you can do it, the SIKORSKY PRIZE. Well, I must confess that one of my dreams and one scope of this web is to create a community interested in winning this prize. I’ve got a pair of good ideas… but I need a lot of help!

 There have been some good attempts but no one has beaten it.

 I recommend you read this article from Wikipedia about human powered aircrafts. If you follow the links and investigate a bit surely you’ll be amazed.

 Here are some links and papers:

 PLANES:

HELICOPTERS:

  Human Powered Helicopters Wikipedia

ORNITHOPTERS:

 Popsci.com (paper and video)

 If you get bored this weekend:   a DIY project (I recommend you to subscribe this podcast. (Amazing!!)

 AIRSHIPS:

 http://www.endlessflyers.com/StephaneroussonUK.html (web and video)

 Well, you’ll need a strong coffee to assimilate all this information, but please never stop innovating!
