From his Brickshelf Gallery http://www.brickshelf.com/cgi-bin/gallery.cgi?f=435575 , Nico71 posted four "Drive Train Ideas" (the third one of which is Zblj's idea). Nico71 wrote the following comments about the four ideas pictured below [NOTE -- I corrected his English a bit, since French is his native language]:

1: Basic axle with U-joint -- reliable but the U-joint can be broken with torque. Be careful and use with a portal axle (8/24 reduction after the U-joint).

2: Bevel gear axle -- without U-joint (save U-joint). Not very reliable because with a lot of weight, there is a lot of friction (steering axle is driven), but this axle is smaller than the U-joint axle. Adapted for a maximun load of 1 kg.

3: Variant of bevel gear axle -- more reliable than the preceding one without U-joint, so this is very strong. Be careful about the 12T gear with a lot of torque. Adapted for a load of more than 1 kg. If the truck is very heavy, I prefer the knob gear (for high torque).

4: My preferred version, without U-joint -- no risk to break any U-joints and no Bevel Gear. It is without the friction of steering axle because that axle is not driven directly. This type of axle can support a lot of weight without friction, and is reliable. Credit goes to Zblj because he has developed them on his third TT.

There are some great suggestions there!

Sorry, this is an off-topic question, but what software is used to create those images?

Thanks,

Daniel

Great work with these.

LDraw (MLCad) for building the model and probably LDView for the rendering

Here are two more made using pulley wheels:

and:

an variation of number three is

and this

Are those all Nico71's designs? Number 3 looks familiar.

the Axles in my post are my invention

number 4 is from Zblj

Oh ok. This is the design that I was thinking about. This was the first one that I had seen these pieces used like that.

The actuator parts are really Genius. I have already used it in the January 2009 in my ETU. But in Vehicles with bigger tires than the 81.6 is the risk of bevel gear crushing too high.

hep, I want to clarify, I don't tell anything if I was the author of all the ideas. There are just examples, I created lot of axles in Truck trial and this picture is designed to show you the different possibilities, so this is not exhaustive, just a attempt to a TT dispersion. For the render, I use SR3D builder, which is faster than mlcad. :)

Dlulders : thanks to have corrected my mistakes, as you said, english isn't my mothertongue. :)

Ah, I wasn't in mistake when, seeing the pics, I thought about SR 3D ! I usually used Leocad, now I prefer Sergio's software.
