    ici détail sur le potentiomètre de 10 K
    j'ai fait en fait comme tout le monde ... l'axe du moteur a été rallongé avec un axe de 6 mm relié à celui du moteur avec une vis m5 sans tête et j'ai percé la plaque arrière du moteur pour laisser passer l'axe de 6 mm
    la liaison de l'axe potentiomètre est réalisé avec une bague en alu percée a 6 mm avec 2 vis pression m 5

    detail here on the potentiometer 10K
    I did actually like everyone ... the motor shaft has been extended with a 6 mm shaft connected to the motor with a screw m5 "headless" and I drilled the back plate of the engine to let the axis of 6 mm
    binding of the potentiometer shaft is formed with a pierced aluminum ring 6 mm diameter screw with two pressure m5

    Salut Mazak515 !
    Content de voir que tu as avancé malgré les soucis : ça prend forme et c'est nickel !
    Bientôt tu pourras nous montrer des vidéos en action :)

    Hi Mazak515!
    Happy to see that your building keeps on going even with some worries: it looks really good!
    You'll soon be able to show us some videos of your sim in action! :cool:

    Salut RacingMat en fait la il faut surtout que je me préoccupe d'acheter les cartes et l'alim pour piloter mes moteurs
    mais j'ai la mauvaise habitude de faire 50 choses a la fois mais là mon ancien playseat est en pièces car j'ai déja récupéré le pédalier pour le 2DOF donc si je veux jouer ... je doit m'affoler un peu !

    hi RacingMat in fact it is especially important that I care to buy the cards and the power supply to drive my motors
    but I have a bad habit of doing 50 things at once but then my old playseat is in pieces because I have already recovered the pedal to the 2DOF so if I want to play ... I must frighten me a little!

    Là le cardan qui relie les 2 parties
    pour assurer en car de problème j'ai fait en sorte que le maximum de parties soit démontable en cas de casse de déplacement ou d'évolution

    les 2 rondelles qui sont soudées sont aussi taraudées avec des vis m8 a 120 ° pour fixer l'axe au socle de ce fait il est facilement changeable

    There driveshaft that connects the two parts
    for bus problem I made sure that the maximum parts can be dismantled in case of breakage or displacement changes

    2 washers that are welded are also tapped with M8 screw to secure the 120 ° axis base thus it is easily changeable

    sur l'axe du cardan j'ai réalisé 2 plats afin de l'indexer les vis sont accessibles par l'arrière

    the gimbal axis I realized two dishes to the index screws are accessible from the rear

    thank you RaceRay
    more pictures coming!
    yes indeed it is very convenient to have to work cnc
    but it's my job so I took the opportunity
    but I took my time to make this one, having encountered some unexpected on my previous rélisations
    best wishes likewise!

    merci
    d'autres photos arrivent !
    oui en effet c'est tres pratique d'avoir des cnc pour travailler
    mais c'est mon travail donc j'en profite
    mais je prend mon temps pour réaliser celui ci, ayant rencontré quelques imprévus sur mes précedentes rélisations
    meilleurs voeux pareillement !

    Voici la base en alu qui vas supporter le pédalier, l'arceau qui supporte le volant ainsi que le siège baquet
    les profilées sont récupéré sur mon premier support réalisé apres l'achat du volant G25
    c'est du profilé " ELCOM " en 40x40 mm les équerres et les embouts arrondis sont réalisé par moi en fraisage classique
    les platines sont elles réalisées en cnc

    Here is the basic aluminum that'll bear the pedal arch which supports the wheel and the bucket seat
    profiled are recovered from my first support made after buying the G25 wheel
    this is the profile "ELCOM" 40x40 mm squares and rounded tips are made by me in traditional milling
    the plates are they made of cn

    les rainures du profilé font 8.2 mm j'ai donc fabriqué des goupilles de 8.2 mm cela m'aligne parfaitement tous les éléments
    the grooves of the profile are 8.2 mm so I made pins 8.2 mm it aligns me perfectly all the elements

    voici l'arceau qui pivote pour venir loger le volant dans les siège ....
    cette pièce est en aluminium carré de 30x30 les coupes angulaires ainsi que les perçage ont été réalisés en cnc
    je devais initialement faire souder ces 5 parties j'ai finalement choisis un autre type d'assemblage qui a mon goût est plus esthétique .
    J'avais aussi peur de la déformation due a la soudure
    seule 4 douilles seront soudées pour eviter un écrasement du tube lors du serrage de celui si et permettre aussi un pivotement parfait

    cette pièce reçoit aussi la colonne de direction réglable mais j'y reviendrais plus tard ...


    Here the arch that rotates the wheel to come stay in the seat ....
    this piece is aluminum square 30x30 angular as well as drilling sections were made in cnc
    I had initially to weld these 5 parts I finally choose another type of assembly that is my aesthetic taste.
    I was also afraid of the deformation of a welding
    only 4 sockets are welded to avoid crushing the pipe when tightening that if and so allow a perfect pivoting

    this room also receives adjustable steering column, but I'll come back later ...

    les vis utilisées ici ne seront pas celles utilisées pour le montage final ...


    screws used here are not those used for final assembly ...

    détail sur les pièces qui m'ont permis d'éviter une soudure sur les tubes
    il y a 8 pièces en tout elles viennent coiffer les deux parties afin d'aligner mes coupes parfaitement ces pièces sont réalisées en cnc bien sûr !
    au final l'ensemble est tres rigide et sans jeu !

    detail parts that have allowed me to avoid welding on pipes
    there are 8 rooms in any style they are both parties to align my cuts perfectly these parts are made of cnc course!
    the final assembly is very rigid and no play!

    Maintenant la partie du pédalier
    cette partie est elle aussi tout en aluminium profilé en 30x10 retouchés en cnc et 2 axes en acier "ETG100 " 1 de diamètre 12mm et l'autres de diamètre 14 mm.
    Les embouts sont eux réalisées en cnc ainsi que les fixations des pédales, qui elle sont en PTFE " plastique " cela évite un problème d'interférence électriques entre le socle "les moteurs" et le G25
    ces dernières permettent un réglage indépendant de chaque pédales, réglage:
    -latéral en coulissant sur les axes
    - hauteur en utilisant les différents trous de fixations
    - profondeur avec l'ajout de cales
    la pédale de frein a été volontairement placé a gauche de l'axe du volant car je me sert de mon pied gauche pour freiner

    Now part of the pedal
    this part is also all aluminum profile 30x10 retouched in cnc and 2 steel axles "ETG100" a 12mm diameter and the other 14 mm diameter.
    The tips are made of cnc them and fixing pedals that it is PTFE "plastic" it avoids a problem of electrical interference between the "engines" base and the G25
    they allow independent adjustment of each pedal adjustment:
    -side sliding on axes
    - Height using various mounting holes
    - Depth with the addition of shims
    the brake pedal was deliberately placed to the left of the steering wheel axis because I used my left foot to brake

    voici quelques images de ce vas donner l'ensemble final il manque encore quelques pièces
    mais au moins vous aurez un aperçu de ce que cela vas donner
    ;)
    Here are some pictures of what will give the final set is still missing some pieces
    but at least you get a glimpse of what it'll look like;)

    looks good, I see the motors are very close the the pivot, and you are using wipers so it will be interesting to see how it goes. Big 12v DC worm gears may be better, but hey, start with what you have.
    I ran a similar setup a while back using wipers and went to big worm gears later.
    http://img231.imagevenue.com/img.php?image=397245800_IMG_0907_122_177lo.JPG wipers in photo.
    Immediate improvement using fatter motors.
    What controller are you using?

    Cheers, David.

    mes axes moteurs ne sont pas directement reliés au plateau mobile
    j'utilise un renvoi d'angle, similaire aux suspenssion comme une formule 1

    my drive shafts are not directly connected to the movable platen
    I use an angle, similar to suspenssion like a Formula 1

    a bit like this:

    My Motion Simulator:
    DC motor, Arduino, 4DOF
    les avantages sont multiples: en gros je pour une course maxi de 140 mm au niveau de l'axe du moteur, j'en restitue que 70 mm pour le mouvement du plateau
    donc, plus de precision dans le mouvement et le couple moteur demandé pour le mouvement est moins important
    effectivement pour commencer je vais garder ces moteurs

    mais je reflechis a une alternative avec 2 verin hydraulique
    dans une voiture moderne les directions assistée fonctionne avec une pompe hydraulique en 12 v et les verins qui sont posés sur les cremaillères de direction sont a double effet .... je pense que c'est une idée a refléchir ...

    benefits are multiple: for a maximum stroke of 140 mm at the axis of the motor, I restores 70 mm for movement of the tray
    therefore, more precision in movement and motor torque required for the movement is less important
    actually begin I'll keep these engines

    but I think about an alternative with 2 hydraulic cylinder
    in a modern car the assisted directions works with a hydraulic pump 12 v and cylinders that are placed on the steering racks are double acting .... I think it is an idea to think ...

    Yes, ok, understood. I can see from the video that the SCN connect further away from the pivot than your motors, but what you have should do the job well.
    heres a vid of my old wiper setup, granted the motors were at rear and not at the front, but it works, and yours should do very well.
    Hydraulics, if you have the money to set them up that would be interesting. Thats probably why most of use use DC motors or actuators. Cost factor.
    As suggested, the big dc motors are surprising to say the least. Perhaps do not rule them out yet.
    And you use the arduino, groovy.
    Good luck with the build, its looks good so far, very nice job.
