8466 Wheels

[darksheep]

Hi I am lucky enough to have gotten the 8466 set of bricklink .

I now want to use the wheels for an off road moc I want to build (i be leave in designing a bit before I start to build )

Does anyone have any ideas or links to pics of how to attach the big wheels to a drive hub or some thing cause I think just putting a drive axel through the center of the wheel and connecting gears to the axel and then a motor to that would cause to much strain on the axel .

Thanks for the help

The 8466 comes with a complete set of parts to make a wishbone-suspension, so you should have all the parts needed & an instruction how to use them. As far as I know, this is the best way to connect these big wheels to a drivetrain.

I'm looking at my son's Lego 8466 4x4 Off Roader right now in my hands, and I can see how folks would be tempted to motorize it. There's quite a lot of room for Power Functions components. The 8466's steering pieces (shown below) are very good to use in other MOCs. A fellow named mbmc137 has motorized the Lego 8466 Off Roader kit: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=414313 . He left his e-mail address and 3 videos on that Brickshelf gallery; maybe you could e-mail him for additional info.

Thanks sounds cool but I do not want to use the wish bone suspension part for my moc cause it won’t work for the moc. I want to put the motor right near the wheel and then build a long strong strut to hold the body all the wheels will turn and be linked independently.

Best way to think about it is a spide with 4 legs but the legs have a motor and wheel at the end of them (sorry best way to explain dont have time right now to build an example )

Thnaks that is cool i might just do this to cause it looks fun :)

The original CV joints are really weak, and I advise you not to use them for high torque. Instead use the pulley wheel to reinforce the wheel and a CV joint like this:

I used the pulley wheels on both sides of the wheel in my old model:

I tried motorizing my 8466 once using a single XL motor near the engine, so that it made use of the gearbox, and it worked reasonably well at a slow speed after a few minor adjustments in the drivetrain. Beyond the first gear though, it basically had to be lifted off the ground (like 8448) to move reliably. Putting the motors near the differentials as in the pictures posted above is probably a better approach in terms of reliability.

Yeah, they are seemingly designed to be powered by the wheels, not the other way around. They are still strong enough to move a motorized 8466 though.

Your solution is pretty nice. Is there any reason you're using the gray pins there instead of friction pins?

[Zerobricks]

Yes, grey pins are smooth, and this allows the CV to run smooth at an angle.

What is the part number for that 3 pronged part that is connected to the wheel ?

Here it is.

Does that setup really work well?

Ye it seems to work well !! thanks for the help
