[WIP] 6x6 Offroad Truck

[VKTechnic]

Newest update: Completion! See the completed model here!

I've had a 3rd pair of Axial Ripsaw 1.9 tires lying around for quite some time, and I figured it's about time to use them. I'll be building a 6x6 truck based on this:

So far, I have the axles done:

Thoughts?

Good luck with the cv joints between the two rear axles. I have never succeeded at getting them to function in the manner it appears that you will be using them.

What features do your axles have?

-lockers?

-gear ratio?

-portal hubs

-4 links/torque arms?

-caster/kingpin/ackerman?

Axles have portal hubs and will be suspended on a 4-link system. Gear ratio is 5:1.

It looks impressive with all those tires!

I agree that those CV joints will fail very fast even if they are geared down in the portals..

I was gonna use the CV joints if there's a lot of stress on the driveshaft (from the 4-link geometry). I just tried it with UV joints and it works alright :P

Looks really awesome so far! Maybe you can make a Mercedes Amg 6x6,

[TheItalianBrick]

Now we are talking! Impressive and I already love it!

The same here....the joints look too fragile!

[HorcikDesigns]

Am I right that you have differentil lock in the first and third axle?

There are no differentials at all on this truck. 1st and 3rd axle are both steered, though

LOL straight to the point!

Ok, futile hope :D GL at building. ;)

Are you sure that those CV joints won't break? It may be stronger to use universal joints with an extending driveshaft. This does look very nice so far though.

Already answered this question above

Update!

Good news: I have a chassis. Bad news: I also have grinding gears.

Looks really awesome so far! Maybe you can make a Mercedes Amg 6x6,

Does your Mini AMG need a big brother?

Who knows... :) Why is the front axle tilted so much?

It's the simplest way to add negative caster to the front axle.

[Zerobricks]

If you think its needed But watch out for the angle of U joints.

[Black-Build]

which gears are grinding?

[Doc_Brown]

Looking good! Those tires sure are awesome!

I would lose the front caster tho, it just isn't needed and will help save those joints!

[Rishab N]

Looks badass with those tires

[VKTechnic]

Good news: I'm back to working on the 6x6. Bad news: the new gearbox is still clicking.

[Black-Build]

Can you post some pictures of the gearbox?

I'll model the gearbox in LDD and put up some screenshots from there, it will be clearer.

Never mind, here's a picture of the gearbox, with the skipping gears circled.

Wouldn't it be better to use one 12 tooth gear with a half bush on each side to make it inline with the 20 tooth gear?
