SCN5 Racing Rig Schritt 2

Hi,

lange hat dieser Abschnitt des Projektes gedauert, aber nun ist er abgeschlossen. Nachdem ich im Januar das Basis Rig vorgestellt hatte zusammen mit dessen Bauanleitung, möchte ich nun die Evo Stufe II zeigen. Diesmal gab es ein Upgrade in Sachen Pedale und X-Sim Full Motion.
Die Pedale waren ursprünglich 2er Eccis mit Moto PC die ich aber auf 3 Pedal umgebaut habe. Zudem musste ich die bei Lieferung völlig verbogene MotoPC Gegenlagerung modifizieren. Der Vorbesitzer muss wohl über dessen Konstruktionsschwäche verzweifelt gewesen sein, und sich zum für mich (preislich nicht arbeitsaufwand) günstigen Verkauf entschieden haben.
In Sachen Full Motion habe ich mich für die SCN5 Lösung entschieden, da ich keine Lust auf Platinen Löten hatte, und die Geschwindigkeit der Servomotoren haben wollte. Da der Preis attraktiv war, hab ich mir gleich für das 150mm Komplett Starter Kit von Simxperience entschieden. Die Blackbox mit Netzteil und USB Kontroller war da quasi gratis Goodie. Gleichzeitig habe ich gleich die SCN5 Dämpfer / Halter mitbestellt. Als zusätzliche Dämpfung habe ich noch Conti Maschinendämpfer eingebaut, quasi eingebaut wie in einer Querlenker Konstruktion.
Erst einmal ein paar Bilder, dann mehr Worte in den Kommentaren.


Anbei der Blick von hinten. Seitlich im Seitkasten ist der X-Sim PC untergebracht, und sämtliche Verkabelung, die man nicht sehen soll. Zudem ist dessen obere Abdeckung eine klasse Ablagefläche für Maus und Fernbedienungen oder auch ein kaltes Getränk.

Der Blick von vorne zeigt die Ecci Pedale, die ich fast noch weniger missen möchte, als die X-Sim Funktion. Zudem sieht man die Nabelschnurr. Zum Sim geht nur ein Ethernetkabel, USB und ein Kaltgerätestecker. Diese sind trennbar, und so kann ich das ganze Rig schnell überall im Raum auf dessen Möbelfilzrutschern verschieben. Seitlich ist der 12 Zoll Touchscreen zu sehen, der für die Bedienung des X-Sim PCs zuständig ist. Das Lenkrad ist gerade etwas hoch eingestellt, da vorhin ein Kollege zu Gast war und Probe gefahren ist. Man kann das Lenkrad in Höhe, Abstand zum Fahrer und im Winkel verstellen. Die Pedale kann man auch im Abstand verschieben und im Winkel einstellen. So kann jeder Fahrer von 1,50m bis 2m fahren.


Nochmal der X-Sim PC. Ebenso zu sehen der selbst gebaute BMW 5er Seq. Shifter


Die umgebauten Eccis. Das wabbelige M3 Gegenlager das alle Kräfte in Verbiegen umleitete, und nicht in die Hydraulik, wurde durch stabile 20*20mm Alu Profile umgebaut.


Die zusätzliche Dämpfung. Durch das verschieben des Gummidämpfers nach vorn oder hinten auf dem Querlenker ändert sich die Dämpfung.







Die Stabistangen und das selbstgebaute Kardangelenk aus Standard Teilen aus dem (nicht Original) Item Sortiment.

Great job.

Very nice and clean.

Hi Mike,

and thanks to your Mustang Profile from the Iracing Board I have a lot fun. This Profile is amazing! I tried it my own and the first test drives were fantastic, but with yours... This was another class of quality. I wished there were more profiles from you for 2DOF :

Hi Henning,

The sim looks great. Very clean!

I dont' see any scratches on your floor, so obviously your combination of dampeners is working

The next version of the Commander will make it much easier to generate a 2DOF profile from a 3DOF or 6DOF+2DOF profile. For now though, you could load one of the 3DOF profiles and then remove the rear axis, and save it with a new name. If you do this, don't forgot to remove the rear axis values from the Synaptrix section also.

Hi Ray,

I think there are two new innovations. First the really good working dampner (I will make a video of the dampner section and post it) and the self made universal joint that needs no welding or other complicate technics to build.

I choose different source. Most parts are from SMT in Reutlingen. Cheap and only 15min from me. Parts they didn't had (fasteners for the white wood boards) I ordered at Ebay (Endederabzocke)

I wanted to build the uni joint because I didn't want some stabalizers, but without there is some play, that produces ugly noise. Now with the stabilzers everything is perfect. I needed 4 of the rotation angles, each for 2 Euros and some centimeters of the 4 by 4 cm profile. In the middle there is a small part of it where all 4 rot. angles are mounted to.

Hi Henning,

I have quite a few profiles that I've been working on that I'll be making available very soon. I like your dampening system and U joint assembly at well .

Also like the sequential shifter. Please give some more details about it's design.

....Mike

The shifter is an old BMW E39 (5 series) Steptronic gear lever. I only removed everything from that assy that isn't needed anymore, and then you you have an shifter that is heavy duty, and realistic like in a real car. It's very easy to to connect. because there are 4 wire , 2 for each micro switch. Just connected to an usb controller, and there you go.

then will look forward to the new profiles. Yesterday a friend of mine tested the Dallara Indycar in Iracing with the Mustang Profile on Lime Rock. That was a fun. 8)

hi,
sehr saubere arbeit.

Very nice setup!

I really like how easily you can adjust almost everything.
Do you think the extra dampening is needed on top of the Simxperience dampeners? Does it make the lighter frame bounce around a lot less?

While building this Rig I first tried the extra dampning with the one piece dampner bar in the rear like many other here did it. But my Continental eampners were too soft for this setup, so I first tried without extra dampning. The result was not so good. The effects were extremly hard, not like in real life. I had to go down to ACC <200. Now I can choose every value I like and the feeling driving on the rim (without tire) got more realistic. I chose the single independent suspension because I wanted to try it. Now every SCN5 can do his own thing and I can tweak the dampner hardness very easily.

Sorry for writing the first article in German, but time was a matter yesterday evening. Perhaps I make a translation, later.

Just made videos, quite dark, should make new one, but that isn't so easy when using a projector.

First the video of the extra dampning, the Lime Rock with Mustang Iracing Vid is being uploaded at the moment.

very nice work,very clean.Do you know if you press ctrl+ re pag or av pag the numbers will be more smaller o bigger?
sorry for my english.

I just uploaded some pictures from the build, because there were some question on the Iracing Board concerning the universal joint:

Hi Henning,

Again congrats on a fine build. Can you give us an idea of costs for the various parts to build this sim?

Hi Bernard,

if choosing the right dealers for the parts it can be reasonably priced. So I have one dealer for the profiles itself, one for the fittings and one for the things that dealer #2 don't carry :

I made this rig in two steps. The first step without motion I documented in another German sim racing board. At that time I spend around 300-350 Euros for the frame. For the motion Update I spend another 200-250 Euros. I cannot tell it 100% because dealer #2 is a nice man and didn't bill me at my last 3 visits when I needed some extra parts. At all you can say 8 Euros per metre for the profiles and 2 Euro per bracket. The extra fasteners for adjustable parts costs a little more.

PS: I have to say thank you. You did a great job. Nice Parts and perfecty fast shipping :clap:

That is an amazing price for the profiles! Here in the U.S., Mr Burns paid nearly $1000 and I don't think he had as many parts as you, or the plastic caps, etc..

Most people here say that this stuff is extreme expensive, but first I love that LEGO for men and second, you can do everything with it and changes are made instantly. You could go a little cheaper when using special steel profiles from Air Cond. resources, but these aren't so nice looking and have very sharp edges.
I saw the american prices that are at least triple of that we have to pay. Why? Are they imported from Germany? Is there a patent on?
