  • XM808 was a proof of concept vehicle created without requirement by Lockheed Missile and Space. Three were built for the Army for testing for lunar operations, the fascinating armed and armored version is found today at the US Army Armor and Cavalry Collection, Ft Benning, GA.

    Two transmission shifters so you can put one in neutral. I'm betting they also hoped you could "trailer" the main body and run on the front engine only. The crew cabin would use the rear engine for electrical. So there are situations in which you'd be in rear-neutral idling to run the hydraulics and front engine in drive for roading. Makes it even crazier.

    It reminds me of a logging skidder. If you have never seen a logging skidder, it is a very specific vehicle designed to drag or "skid" logs out of a forest.
    For this concept, they added 4 more wheels, changed the chassis a bit, added engineering for higher speeds, added a weapon mount, and painted it green.
    Still, if they took this concept and applied more current engineering technologies and safety/comfort features, I could see something like this being very handy for mechanized recon missions in places where good roads are a luxury.
    Thank you for going over this machine. I learned something new today for sure. :-)

    • @mochaholic3039

      Log skidders are an interesting bunch, the early ones were literally steam locomotives on treads. The Lombard steam hauler had an unique tread system, a tread within tread to eliminate friction in the days before oil-based lubrication was available, and it worked pretty well. The thing moved at 4mph but could drag 300 tons worth of logs. I should mention I came across an abandoned Lombard deep in the forest I was hiking in some years ago, the thing was pretty intact despite sitting there for nearly 120 years and got me interested in log skidders.

      I actually built log skidders for J. I. Case. I believe they only built them a few years. Possibly because of high maintenance of that bearing that let the rear "twist" separate from the front. The articulated bearings worked just fine. The rear fenders (the part that you would pull a log into) were a half an inch thick. I dropped one on my finger (only about a two inch drop) and I can say, they are HEAVY!

      @@jimnotter6046 What knocks those center bearings (actually bushings) out is people not knowing how to drive them and turning until it slams into the stop pads.It was worse on the old skidders that depended on RPM to pump the hydraulic pumps fast enough to turn quickly.The old Timberjack is a good example of needing RPM's to turn it,one of the reasons those old 353 Detroits were called screaming Detroit Diesel because if you wanted to turn moderately quickly you need to have your RPM's up.I ran a old Tj 240 with aerial bucket for years,another crew had a 225,then later a JD 440 logging or clearing right of ways for power companies in 4 states.The Tj was a much better machine.

    I've always loved this thing ever since I picked up the AFV Profiles book on it in a 2nd hand bookstore. Looking at the mechanical transmission complexity, this has to be a design that would benefit hugely from electric transmission, with the engines just driving generators and a motor in each wheel hub. The ENGASA company from Brazil had a patent on a slighty different form of walking-beam suspension, and sold large numbers of them, both on armoured vehicles like the Cascavel and Urutu, and also on unarmoured 6x6 trucks.

    One feature was that the steering hydraulics ran off of the front engine. There was a axle pump, on the rear section, that was a backup for the steering, in the event the front engine was not operating, that would provide hydraulic pressure to operate the steering once the vehicle was rolling about six miles an hour.

      Everyone seems to forget Electric engines are heavy and expensive.
      And hub motors are terrible mostly due to Unspung mass.
      Springs make your ride comfortable and shove wheels back onto the road faster than gravity would allow.
      Heavy motor wheels take longer to get back onto the ground.
      And the amount of electricity to run any 4 of those wheels? High.
      The machine as designed could have saved a lot of power losses through better transmission layouts and removing geared power transfer.
      However They were trying to print 4 copies on the cheap as proof of concepts, not as final delivery machines.
      So easy to print cogs shoved inside some metal bars are easy, but individual drive shafts for all four rear wheels? expensive, but lighter and lower power losses.

    Given the number of gears in the rear portion of the vehicle, it is unsurprising how loud it would get while riding in it. To save costs, they would have been spur gears, so they would have been noisier than helical gears. Helical gears would have been less noisy, but the fuel economy would be even worse.
    This is one of the few vehicles which would have been better (not cheaper) if Ferdinand Porsche had designed the power train, as running electrical conductors to electrical motors in the wheels may actually be more efficient than all of those spur gears.
