Hello + beginner questions

[yokoyoko]

Hallo x-sim forum,
mein Name ist Mirco und ich komme aus Bad Eilsen in Deutschland. Vor ca. 2 woche habe ich ein g25 bekommen. Seitdem wird fleißig gtr2 und co gespielt. Auf der Suche nach setup's für das Lenkrad bin ich bei euch hängengeblieben. Vorweg: absoluter Wahnsinn und echt verrückt was hier so geht! Da ich für sowas "leider" immer leicht zu begeistern bin, habe ich mir jetzt in den Kopf gesetzt - sowas möchte ich auch haben.

Ich habe mit Catia mal "quick & dirty" ein 3d Modell erstellt. Dabei habe ich mich ganz an dem orientiert was ich hier so gesehen und gelesen habe. Frex-style, richtig? Das ganze soll mit Sabbertooth, Vm110 und Wischermotoren betrieben werden!



Wischermotoren sind nicht erste Wahl, aber das ganze Projekt soll erstmal so günstig wie möglich realisiert werden.

Zu meinen Fragen:

1. Ist die Ausführung so wie dargestellt generell sinvoll, oder gibt es für wischermotoren bessere Ansätze?
2. Wenn für die Lagerung unter dem Sitz ein Schwingmetalllager verwendet wird - http://www.maedler.de/Product/1643/1626/2183/600.aspx - welcher Durchmesser ist dann sinnvoll? Ich dachte so an 40mm, oder ist das zu steif bzw. überdimensioniert - zur verhinderung von torsion des Sitzgestells werden noch zwei Streben angebracht.
3. Ist ein Kardan als Lagerung besser geeignet?
4. Ist der Winkel der Wischermotoren egal, oder ist es sinnvoll die Motoren an den Winkel der " Stangen " anzupassen? Also das der Hebel des Motors mit dem Punkt der oberen Aufnahme fluchtet.
5. Welche Hebelarmlängen für die Wischermotoren
6. Welchen Winkel für die Motoren? 180°, oder lieber weniger

- Kann eventl auch jemand allgemeine Maße seines Rigs posten, oder mir einen Link nennen an dem ich mich orientieren kann. Mir geht es um Maße für das Sitzgestell mit Winkel für die Strebe dahinter sowie deren Länge, die MAße des Grundrahmens, der Lnekradaufnahme.

Ich weiß das sind eine Menge Fragen. Ich hoffe es ist nicht zu dreist mit dem ersten Post - habe wirklich viel gesucht, aber entweder bin ich blind, oder überlese die wichtigen details.
Für Antworten und eventl. Hilfe im Voraus vielen Dank.

Ps.: Entschuldigt das schlechte " Googel-English "

Hi x-sim forum,
my name is Mirco and I'm from Bad Eilsen in Germany. About 2 weeks ago I've got a g25 for present. Since then, hard played gtr2.

Looking for setup's for the steering wheel I'm stuck with your forum. First of all: absolutely insane and really crazy here! !::
I've been using Catia "quick and dirty" created a 3d model. Here I am completely dedicated to what I have seen and read here. Frex-style, right? The whole is to be operated with Sabbertooth, VM110, and wiper motors!



Wiper motors are not first choice, but the whole project should first be implemented as cheap as possible.

to my questions:

1.) If the execution generally quite useful as shown, or are there better approaches for wiper motors?
2.) If used for mounting under the seat is a rubber-metal bearings - [url] http://www.maedler.de/Product/1643/1626/2183/600.aspx [/ url] - which diameter is useful? I thought at 40mm, or is it too stiff or too large - for the prevention of torsion of the seat frame are two struts attached.
3.) Kardan is better suited as a rubber-metall?
4.) If the angle of the wiper motors do not care or it is useful to the motors on the angle of the "rods" adapt? So that the lever of the motor with the point of the upper retainer aligned. sry for translation -i hope you can understand
5.) Which lever arm length for the wiper motors
6.) What is the ideal operating angle of the motors? 180 °, or rather less

- Can someone post some general dimensions of its rigs, or give me a link where I can get some dimensions. I am concerned with dimensions for the seat frame with angle of the strut behind it as well as their length, the dimensions of the base frame, the steeringmounting
I know a lot of questions. I hope it is not too bold with the first post - I really searched a lot, but either I'm blind, or read about the important details.
For answers tolls. Help in advance thank you.

Ps: Sorry for the poor "Googel-English"

One thing to suggest, use Pololu JRK's http://www.pololu.com/catalog/product/1393 easy to wire, and one board per motor. Less mucking around setting up.
I have added a general sketch of a seat mover, which is what you have planned.
This was designed with 25mmx x 25mm x 1.6mm steel and 16mm MDF sheet wood.

Thanks for your reply.

What is the main advantage of the ploolu? The Sabertooth is availible in Germany and is a bit cheaper. Will the "dynamic speed setting" help with the sabbertooth, or is for wipermotor use not the way to go? like - http://www.dailymotion.com/video/xij0ju_essai-simulateur-dirt-2_videogames

edit.: pololu also availible in germany...

In combination with the Pololu what is best to use? - also the Vm110?

The JRKS will run 30 amps continuous by the way

[yokoyoko]

Ok. Thanks!
Now I understand that i will need 2 Jrk's and that is does the job of the 8055 too.

in summary pro's of the Jrk:
- 30 Amp (max) per motor (more futuresave for bigger motors)
- 12 bit instead of 8 bit resolution
- Way to setup with x-sim?

You convinced me by the electronics - i will give 2x Pololu a go - (I own a Weller Solderstation - but everthing smaller than a 1mm wire is critcal ).

Can someone please say something about Kardan vs. Rubberbushing for centering the motion. What length of lever do you use for the wiper's and is the angle of the motor important or is it not important because of the circular orbit?
(With the info of the leverarmlenght i want to do a mtotionanalyse with catia.)

If you are using wipers, start with the standard 40mm centre to centre arm thats on the things.
I think you may be overstretching the wiper with a long arm. Although I am sure Bobbuilt will prove me wrong

Also is a pic of how to wire up the jrk ,and an example photo of how the pots connect the the levers for feedback.

Wow I'm very impressed by the support here! Thanks Great forum

With your information i tested a bit more. You said angle of ~20° - do you mean this for one direction or together?

Example:


With this setup: - motortravel= 60°up, 60°down - leverarm=80mm - wipermotors in angle with the upper mounting points - other dimensions orientated by your prev. post
I got the following corner-movement: left=11° - right=11°
For acceleration=6° - for braking=6°

What do you think? Ok, or should i change geo in any way? By your experience is that enough travel and is the splitting of cornermovement and brake/acc good for a go in real?

Gruß Mirco

[motiondave]

ummmm.....bobbuilt, youd better answer this

[yokoyoko]

Hi,
last week two pololu 12v12 arrived. Also two wiper motors of a vw golf and a power supply.
Bevor i go on, Bobbuilt or others - in your experience - is the geometrie/movement ok? Or are there any advice to change?

Thanks.

[motiondave]

what do you mean geometric?
