AMEWI TATRA 6x6
 
Hello everyone !
I present you my new truck, an AMEWI TATRA 6X6 :

This is a copy of the CAPO TATRA 8x8.
Well, ok, it lacks an axle, there is no interior, there are no differentials, but for three times cheaper than the CAPO, we will not complain!
Technically, it's beautiful material, the quality is there.
I intend to modify this truck to make it realistic!
See you soon !
Joël

That is a very odd drivetrain and suspension. It seems very simple. I like it. Nice truck!

I dismounted the truck to see how it was done:

It's beautiful mechanics and it seems to breathe reliability
It's supposed to be a Tatra, but there is no logo!
I found on Ebay a pin's, and that's it!

Re: AMEWI TATRA 6x6
 
Thank you for showing the disassembled photos! That's a simple and clever drive train. Very nice truck.

Re: AMEWI TATRA 6x6
 
That drive train is crazy. Just like the real thing. Are the wheels staggered on each side as it looks like the axles are at the center of the beam?

PATROL31000 04-13-2018 12:01 AM

Re: AMEWI TATRA 6x6
 
The axles are shifted as on the real truck.

Re: AMEWI TATRA 6x6
 
The steering setup is also very interesting. Do you have any better pics of it?

HumboldtEF 04-13-2018 04:13 PM

Re: AMEWI TATRA 6x6
 
Yeah thanks for showing us the guts.

One thing that looks odd to me is the camber but maybe I'm imagining it, it just looks like it has a lot of positive camber. Does that go away once its on the ground?

Rock Dodger 04-13-2018 04:50 PM

Re: AMEWI TATRA 6x6
 
I don't see suspension links. Is there anything locating the axles other than the shocks?

This is indeed a curious vehicle.

This is indeed a curious vehicle.

It looks like the axles tubes bolt onto a curved plate that hold contact of the spider gear on the center shaft and allows the tube to flex up and down.

Hello !
To try to answer all your questions:
A picture of the steering setup:
https://imagizer.imageshack.com/v2/xq90/922/g2c4cN.jpg
Pictures of the transmission, identical to that of the real truck:
https://imagizer.imageshack.com/v2/xq90/923/fOwgtq.jpg
https://imagizer.imageshack.com/v2/xq90/923/stLEmM.jpg
Indeed the axles revolve around the central tube, and are guided by bearings:
https://imagizer.imageshack.com/v2/xq90/924/LMnaXK.jpg
https://imagizer.imageshack.com/v2/xq90/924/mNmwiT.jpg
And pictures of the suspensions, which they do not look like those of the real truck, which is equipped with air cushions:

Cool truck,

so its similar to a oversize pinzgauer 6x6 but with the engine in the middle vs the pinz rear engine.

Did you build the chassi, you say its similar to capo?

PATROL31000 04-15-2018 08:32 AM

Re: AMEWI TATRA 6x6
 
The truck is delivered fully assembled, there is just the windows, mirrors and the tarp of the bucket to mount.
But I preferred to disassemble everything to control, and especially to see how it was done!
So after disassembly, reassembly:

https://imagizer.imageshack.com/v2/xq90/922/euQOBm.jpg
https://imagizer.imageshack.com/v2/xq90/922/eg9zI2.jpg
I made a big radio board placed between the frame rails in the back, so I have room for the radio installation!

Now that's a cool truck! Thanks for sharing Joël. Looking forward to seeing what else you do to it.

PATROL31000 04-18-2018 03:42 AM

Re: AMEWI TATRA 6x6
 
The truck made its first laps.
I'm not satisfied, it rolls very slowly, it's noisy, the speeds go wrong. it would require some adjustments, and a little break-in, but the false engine does not please me either ...
Fortunately I have it in stock:
https://imagizer.imageshack.com/v2/xq90/923/Orlqvc.jpg
A 3 speeds gearbox, with aluminium cover.
I restart the original transmission, makes media, and that's it !
https://imagizer.imageshack.com/v2/xq90/922/iWo1WQ.jpg
https://imagizer.imageshack.com/v2/xq90/922/dMQow8.jpg
I'm going to dress the Tamiya gearbox so that it looks like the real engine of the Tatra
https://imagizer.imageshack.com/v2/xq90/923/Okp4tO.png
https://imagizer.imageshack.com/v2/xq90/922/EDk6MU.jpg
so I start with the exhaust manifolds of the original engine:

https://imagizer.imageshack.com/v2/xq90/922/M1sOyd.jpg
https://imagizer.imageshack.com/v2/xq90/924/ZwxTPj.jpg
The sequel soon!

Re: AMEWI TATRA 6x6
 
Hello !
As I intend to reproduce the real engine, and I also want to put a spare wheel, exhaust ... behind the cab, I have a problem: the tray is too long!
So I take out my saw, and ...
https://imagizer.imageshack.com/v2/xq90/923/GhJszN.jpg
I shortened the bucket of the value of a sidewall, so I have room behind the cab:
https://imagizer.imageshack.com/v2/xq90/922/O5J4bT.jpg
https://imagizer.imageshack.com/v2/xq90/922/9uObsp.jpg
Then I modify the attachment system of the bucket. Originally it is screwed on the chassis, which is not practical to change the battery that is below, even if there is a hatch provided:
https://imagizer.imageshack.com/v2/xq90/923/PKdjy4.jpg
So I replaced the 4 screws by 4 bumpers, and now the grab holds with body clips, which is easier to remove it!
https://imagizer.imageshack.com/v2/xq90/922/1wCdxg.jpg
https://imagizer.imageshack.com/v2/xq90/924/K9Qq7w.jpg
https://imagizer.imageshack.com/v2/xq90/924/rPbKoP.jpg
Next step, the layout of the cabin.
Bye !

Re: AMEWI TATRA 6x6
 
I am now attacking the cockpit.
While looking for photos of the interior of the real Tatra, I came across the photos of a scale 1:25 hyper detailed, with more than 1200 pieces. So I bought this model (about $ 20) as a model.
Particularity, it is paper!
https://imagizer.imageshack.com/v2/8...924/lHMTwB.jpg
Just take the ribs on the paper model, multiply by 2.5, and we get the same parts at 1 / 10th!
https://imagizer.imageshack.com/v2/8...924/eR72yy.jpg
https://imagizer.imageshack.com/v2/8...923/p2MXkt.jpg
https://imagizer.imageshack.com/v2/8...924/x7QR1G.jpg
https://imagizer.imageshack.com/v2/8...924/bnKS8E.jpg
The floors fit under the cab, and are screwed with the original holes:
https://imagizer.imageshack.com/v2/8...923/RyL50j.jpg
https://imagizer.imageshack.com/v2/8...923/aT0oLS.jpg
https://imagizer.imageshack.com/v2/8...922/e5IFyU.jpg
Then I continue with the dashboard:
https://imagizer.imageshack.com/v2/8...922/0csmL8.jpg
https://imagizer.imageshack.com/v2/8...923/NO5gdu.jpg
I had to back a little engine to set up the interior. So I redid supports and shortened the drive shaft:
https://imagizer.imageshack.com/v2/8...922/pEwwLT.jpg
The sequel soon!
Bye !

Thank you for the likes!
I have almost finished the dashboard, missing some buttons:

Very cool. That steering is concerning. I hope it works well.
