Default My new Touring.

Hi all.

As wtcc asked me, I create a thread for the Touring I'm designing. The first prototype is ongoing, but not jet finish. I have too little free time to invest at the car. I design it to run at the GT category with 21,5 or 17.5T motor at my local track in Braunschweig (Germany). The idea is to create a competitive, but simple car. Nothing revolutinary. Shaft transmission, low profile dampers and 100% simetrich lower chassis.

Just a couple of renders of the CAD model. I hope you like then.




Best regards.

Awesome! Finally
Such quality design needs a place where everything is documented.
I am looking forward to the upcoming developments

I use a mix of TT-01 and TT-02 transmission parts. For the first car I'm using a 3Racing ball differential and solid axe. As you can see, all the electronic is placed over a floating plate. Here a picture of the first prototype. As I say is half done. The bulkheads are not the final ones, they are just in PLA printed to validate the design. The finals will come in Nylon-X. The front suspension harm is also not the final one but is printed with the right material. Rear suspension harms will be also printed with Nylon-X. The steering and motor mount is also ongoing. I'm looking what is better (And cheaper), print the motor mount in metal or machined.

It looks really nice. I like shaft drove tourers.
I just have to ask, what's reason for use of TT-01/2 gears? They're quite big and rough, while TB-series gearing is more compact with variety of differential mechanism and gear ratios.

For the motor mount you can use an already existing design if you want to save money:

EXO-SIX.2 MOTOR MOUNT SET, replacement - Exotek Racing

I bought one just in case... you know.

Because I have a TT-01 and my son a TT-02. So I already have some parts. I search for TB differentials and I found only front solid axes. But if you can send me a link I will appreciate it.

The Exotek is pretty similar, but is bigger and the concept how I support the transmission is very different.

On the Exotek motor mount you can remove the support ring. It it attached with a screw. So you end up with the lower motor mount only. The size might help with motor heat ( maybe that is why they made it that big

Looks nice, but anyway, I don´t know if it will fit. The bigger problem I found with the shaft car design is that the space is narrower in compare with a belt car. Could you send me some dimmensions?

That distance is 17mm on the Exotek mount.

This is only complete set I found
https://www.t2shop.de/epages/6174632...2&Locale=en_GB

Gear differential is only available in parts, part numbers are listed in manuals - TB04, 05 and Evo 6 & 7 use identical or very similar units with 2.5 gear ratio, so spare or optional parts can be used from any of these models. List is pretty long, so I'm not sure if I'd be able to list all parts available.

Some parts from TB03 and TB Evo 5 also compatible - those models used ball diffs and 2.43 internal ratio. TRF502 gears, which use 12 3/32 balls instead of 9 3mm, can be used as optional part for TB03 diff. But 03 and Evo5 are more than 10 years old, so their parts are becoming harder to source.

Thanks for your support. That is the main reasond why I choose the TT-01/TT-02 differential. They are easier to find. But yesterday, talking about the DF-03 in another thread, I remember that the DF-03 front differential "could fit". I have to search in my basement for all my old DF-03 stuff and check the front differential, bevel gears and transmission in general. But my first option still being the TT-01/TT-02 parts.
