Nigel's Landie in 4WD Monthly

Good stuff Nigel, thanks for putting those up.

My understanding with the pictures are that if the file size is less than 40kb they will be displayed as pictures. Anything larger than this will be displayed as a thumbnail. The size restrictions may have changed a little in the recent upgrades but I think thats how it works.

Wow all them pictures

OORSUM

awwwwww i can't see any pictures again!!

Nice pics and very nice set up.

Hi

If someone with computer knowledge can tell me how to post the pictures as a thumb that can be clicked to download the bigger image it might be better.

With these bigger photos the download time to view the post will be very slow for those not on cable.

Sorry if this has slowed things down, I can edit the post later.

Thanks

Nigel

Nigel,

Firstly thanks for posting the photos.

Don't be concerned about how slow they load - definitely worth the small wait.

I don't know what controls whether the pics appear as thumbnails. Things to watch are not to exceed the maximum horizontal and vertical size in pixels (800 x 600 I think), the maximum size of attachments in bytes and spaces aren't allowed in filenames.

Irfanview www.irfanview.com is good free software for resizing pictures.

Thanks for posting the pics Nigel, now everything is completely clear. There is certainly no spare room under that thing! And you must have a lot of fun greasing all the grease nipples!

One question - if you drove it when the rear was centrally sprung - what was the body roll like?

Ben

The early drive testing was done offroad at my farm. We had a variety of gullies and rugged terrain to test the articulation and general workings of the concept.

Apart for mods for clearances and strengthening the basic design was fine. Thats not to say that Bill didn't put endless hours into refining and fine tuning the final result.

Off road I seem to remember the centre rear spring version felt stable and handled predictably and well. There was typical Rangie body roll but it felt OK.

On bitumen the road speed handling was going to be a problem for engineering. Bill experimented with many changes but eventually went back to outboard rear coils. The original reason for leaving the outboard springs out was to improve the articulation. After much tweaking Bill was happy with slightly less articulation but much improved road stability.

In the final stages of engineering we noticed rear end tended to lift and yaw under heavy breaking and this was overcome by fitting two additional shockers to the rear radius arms.

The final product is a compromise between extreme off road capability and engineering compliance for road registration. It is also a testament to Bill's imagination and engineering skills

Bill may wish to elaborate on the development detail.

Ben, theoretically the forced articulation system should also provide roll resistance but because of the lash of all the drive shaft slip joints there is some lost motion and still some roll. Considering that by going over to the 5 link front end we have removed any roll resistance that Rover built in, the vehicle handles acceptably well on road and is very confidence inspiring to drive on rough unsealed surfaces.

Wouldn't the additional shockers provide roll resistance?

Particularly if they were valved for "stiff" compression and rebound.

I like the idea of no outboard springs as it would naturally make the suspension more compliant.

Cheers

Yes Mike the extra shocks do add a bit of roll resistance, to an acceptable level. probably in cab adjustables would improve things even more.
I could sense that our engineer would have had a stroke if I presented the vehicle to him without side springs.

saw your video of Bill's 6x6. Great stuff.

Bill mentioned that you may have video of the Hybrid under test.
Any chance of posting it?

I'm sure there willbe interest.

Thanks
Mike

Hello all

Finally found time to edit and prepare some video of the Hybrid during early testing.

Hope some of you find it interesting.

1. Hybrid climbing an embankment.

2. Crossing a gully.

3. Winch testing.

Look forward to some feedback.

nice....
love the V8's note

[daddylonglegs]

As in most cases, videos or photos don't capture the true steepness or severity of obstacles but the bank was very steep and slippery, and the gully was extreme as shown by the wheel articulation.

Nigel,
Thanks for posting those video clips - great truck.
