Hi everyone!
The last release of the Center Hub Steering MOTO2 3D (iges) is online!
To get it you must register in www.lamoto2.es, download filezilla or other FTP client.

Be carefull if Filezilla tries to set a port number. The port box must be clear.
Go to archivos3D/moto24_09_11.zip
And you got it!
Please keep sharing your designs and ideas!
Hi everyone!
As you probably know our Center Hub Steering Moto2 project continues. We’re closing the mechanical design and so we have to started with the bodywork design.
I’ve made the first 3D proposal but as it is an open design project everybody can send designs and people will choice. It’s just I quick draft that I’ll improve if there are no more ideas coming. Do you like it? Too heavy looking? Too complex?
At the moment there is only another design. What do you think about it?
If you’re interested in designing the bodywork for our race bike you can send me your ideas to info@beltrance.com and I’ll publish them in www.lamoto2.es
I think that is a great opportunity to design something that is going to be built and that is going to have a lot of repercussion. Or simply because it’s a great pleasure to see your design running really fast! Please don’t worry if you don’t draw well or don’t know about 3D, we will help you with your design as much as we can.
And remember that you can also help with the mechanical design and the calculus.
Here there is a pic to use as underlay.
And now let’s have a strong coffee and let’s work!
LA MOTO2 PROJECT suspension 1 from Beltrance on Vimeo.
As you probably had noticed, if you used to come to this café, it has been closed for a while. We’ve been really busy with the LAMOTO2 project and with other projects that unfortunately are paused (hope that not stopped)
Here in Spain you can read monthly about our progress but not abroad. So I wanted to show at least a part of what we’re doing.
First of all this little video.
Take a seat and enjoy our delicious coffee!
I have prepared a mini video to show the idea of the system that carries our moto2. In yellow you can see the vertical arm. The thick lines is the part and then up thinner line the real steering axis. The pink line is the top of the steering column of the system, which looks like a fork. When the system compresses the top is “folded”. Therefore there is a ball joint in the joint, to absorb this inclination. Initially the diference is 2 degrees, not zero on purpose. To ensure that the “fold ” goes forward and not backward. At the end it arrives to 7 degrees of tilt for a compression of 120mm. These 7 degrees is absorbed by the green piece that goes in the front of the bike (this is why is a plate) plate that flexes the 7 degrees but kept intact the steer stiffness, work in shear effort. Another thing you see is that the center of the wheel follows almost the same path as a 12 degrees fork. Thus the pilot feel much like a conventional bike and trust the bike from the start.
With this trick, the mechanism, that is an evolution from the patent of the D1200R Demonstener solve the problem of getting a direct steering to the Hub Center Steering System. In this case applied to a system derived from the Difazio. This was one of the desired conditions in the project (no Bump-Steering). If you look you will see that history is an evolution of our prehistoric V2R StreetDumper

SYSTEM 2 CALLED D-D-P (DEMONSTENER-DIFAZIO-PARKER)
It’s based on the mentioned systems. It’s main advantage it´s the arm placed over the wheel. It’s relationed in some way with the Ecosse Spirit system. It´s like system D-D but I think it can be lighter.
The biggest inconvenient it’s probably the cooling. There’s less free space for the radiator in the front part of the bike.
Both systems, as you can see are rod-end free for a better precision, even if they are more complicated and heavier.
What do you think about these systems?
Any idea for a better performance?
Do you a have a better system and you want to see it on the racetrack?
I wait for your comments!
Happy new year dear Readers!!
The project Lamoto2 it’s going really well.
We’ve been thinking about publishing it worldwide with the help of www.thekneeslider.com even if this can make the project too much big for our human resources. However I think we’ll do it because it’s a great chance to meet people interested in this kind of projects.
I’ve done the first proposals while we’re waiting for the readers designs. Readers are really interested and they are mainly giving their opinions and some of them are proposing their ideas.
FIRST SYSTEM it´s called D-D (Demonstener-Difazio)
It exploit the best of both systems. It has a double swing arm single-sided or a double swingarm on both sides. It uses a commercial Vyrus rim and it’s really light an efficient.
irst you can see is the headstock, it´s placed inside the hub. It´s a preliminary design so doesn´t matter too much how is it made. The headstock it’s a part of the system that DOESN’T TURN.
There we have the Hub. It turns with the steering. It has big bearing with small section and so a reasonable weight.
The hub wears also the supports of the callipers. We must still calculate if the headstock allows the loads they produce.
The direction come from a bended plate that works mainly in shear mode so it´s strength enough to hold the efforts.
Over the wheel we must continue with a telescopic cylinder that can carry the steering effort with a compass or with a grooved shaft.
The most elegant solution it’s the Cannondale steering system with needle bearings.
The swingarms can be one-sided or both sided depending of the stress analysis results. We’ll choose the one with better performance.
