the use of ball bushes is not possible.
The standard ball socket, can not rotate and slide at the same time.
there are ball sockets that can slide and rotate, but it is very expensive.

the most reliable and least expensive is the bushings.

My bushings are self lubricated bearings METAFRAM.
The bushings more resistant to dust, shock and

I thought the concept and design for ease of implementation and low cost of fabrication.

l'utilisation des douilles à bille n'est pas possible.
Les douille à bille standard, ne peuvent pas tourner et coulisser en même temps.
il y a des douilles à bille qui peuvent coulisser et tourner, mais c'est très chère.

la solution la plus fiable et la moins chère, c'est les coussinets en bronze.

Mes coussinets en bronze sont des coussinets Métafram auto lubrifié.
Les coussinets en bronze résiste mieux à la poussière, et au chocs

j'ai pensé la conception et le design pour une facilité de réalisation et un faible coût de fabrication.

Indeed, the ball bushes standar not allow to work in rotation, I still Visione the video, it was not very noticeable.
I'm waiting for the next video with the metal structure.

Effectivement, les bagues à billes standar ne permettent pas de travailler en rotation, j'ai visionné de nouveau la video, ce n'ai pas très perceptible.
J'attend la prochaine vidéo avec la structure en métal.

When the cockpit is inclined, for example from left to right, the axes rotate.
But as the poles are fixed, they must compensate for the difference in length diagonally, it is necessary that the axes slide.

On "Force Dynamics" for example, is the cylinders that move.
Cylinders deviate or close it.

To simplify the chassis, I am choosing fixed posts, but must slide while the axes.

you can see on the last video forward and backward axis at a tilt left / right, there is also the rotation

http://www.youtube.com/watch?v=_5CfGsEW ... dvJIOVIsMg

Lorsque le cockpit est incliné, par exemple de gauche à droite, les axes tournent.
Mais comme les poteaux sont fixes, ils faut compenser la différence de longueur en diagonale, il faut donc que les axes coulissent.

Sur "Force dynamics" par exemple, c'est les vérins qui bougent.
Les vérins s'écartent ou ce rapprochent.

Pour simplifier le châssis , j'ai fais le choix des poteaux fixes, mais il faut alors que les axes coulissent.

tu peux voir sur la dernière vidéo l'axe avancer et reculer, lors d'une inclinaison droite/gauche, il y a aussi la rotation

Yes I see.
The axes must be of a diameter sufficiently substantial :?:

Oui je voie.
Vue la charge sur les axes ils doivent être d'un diamètre suffisamment important :?:

yes, i chose 30 mm in steel of course!

oui, j'ai choisi 30 mm en acier, bien sur!

My new plan, octagon support cockpit.
This plan is not yet complete, it gives an idea for it.
there the sliding supports, the position of elements, the axes of the sets ...
Mon nouveau plan , l'octogone support du cockpit.
Ce plan n'est pas encore terminé, il donne une idée vue de dessus .
il y a les supports coulissants, la position des éléments , les axes des ensembles...

@ 2:34min - love to see how smooth it works! 8-) amazing work so far!
:lol: hurry up - we want to see this sim in motion :lol:
