Tatra, more questions

[cranetruck]

It's good to have Tatra owners with us and an opportunity to get questions answered that have been lingering!
Here are a couple:
1) How are the axles configured for highway driving, are they separated by differentials?

2) How do you gain access to the inside of the tube for service? How much of it is filled with oil if any?

Thanks

for highway driving you just use the two rear axles for power. There is a selector to engage the front two offroad if you need it and there is a different selector to lock all 4 axles.

The center tube is totaly immersed in oil, it is not real easy to access inside it but you can take it apart in sections (flanged) the half axles come out pretty easily to do work on them if needed, althogh everything is heavy so its not that easy.

Okay, but is there an interaxle differential, the deuce for example, doesn't have one?

I guess Im not sure what a interaxle differential is, if you see the drivetrain on the youtube video previously mentioned you can see there is a differential on each axle
there is a I guess you could call it a transfer case between the front and rear axles except it is mounted above the tube and bolted on with all mechanisims internal.

RE: Re: Tatra, more questions

Watching the many videos on youtube etc, it looks like the Tatra gets a lot of its performance edge from locking differentials (and, of course, drivers with a death wish) and not so much the independent suspension, which often shows a wheel in the air without ground contact.
Wonder why the locking differential feature is so rare amongst US MVs.....not needed to meet mil spec?

I always wondered the same thing, I added Detroit lockers to my old duece and it did wonders to improve performance. My guess is they arnt really designed for extreme offroad where you would really need it. Luckily you can add it to most any truck.

When you go as extreme as the you tube vids go It doesn't matter what kind of axle setup you have there is always going to be a wheel off of the ground, nothing is going to have that kind of suspention travel.

It may have something to do with the cost of a selectable locker and the fact that "automatic" lockers like a Detroit change the driving characteristics so much. When soldier "A" is used to driving a open differential Deuce and then jumps in one with Detroits on wet pavement, he is in for a whole new experience that would more then likely end up with property damage.
