You'll still need the jack (and cribbing).

Perhaps not as often, but the hydraulic lifting suspension is only going to get the job done in certain situations - such as on a relatively hard and level surface. A 6x6 would probably be able to use the hydraulic lifting more often in more situations than a 4x4, but even so, it won't always provide adequate stability for safely working on the truck.

Yeah, I figured as much too. In standard 6x6 format, if any of the tires on the rear two axles gets shredded, the vehicle will probably be stable enough to change any and all of them simply by retracting the wheel hydraulically, because the rear axles are so closely clustered together. But if one of the front tires blows, it would not be safe to try to change it without a jack in place as well. So hydraulic lifting will makes tire-changing somewhat or perhaps even significantly easier; but it won't eliminate the need for a bottle jack + cribbing.

Now we simply need to hear from campo, about Volvo's new Independent Suspension system.....

All best wishes, and Merry Christmas!

The red MAN truck has solid axle suspension - not independent - so its possible to do the hydraulic wheel lifting without independent suspension...

Is this nearly 100 page thread going to result in anything real?

Yeah - I wonder that too... It does seem to venture off into la-la-land at times. I think 80% of the design could be done easily with one of the 4x4 MB Sprinter super long / high top vans and some creative body work on the rear of it to improve departure angle and add the reach "porch/deck".

Hi Charlie, Haf-E,

Sure, this summer I will post drawings, concept sketches, and 3D rotations and cutaways. But of course none of these will be "real", in the sense of a "real" vehicle. I only wanted my own thesis project to be a bit more grounded in practical engineering and overlanding realities, and a bit more socially and politically sensitive, than some of the more recent examples of "concept expedition motorhomes".

There aren't that many. The only two concept designs I've come across so far, intended specifically for the expedition market, are listed below. I will discuss them at greater length later in the thread. But I wanted to give you the links right now, so that if you are inclined, you might check them out on your own, sooner rather than later:

And for his official website, see http://hamidbekradi.com , but it doesn't appear to have much posted yet.


*******************************************


Both of these were intended merely as "concept" vehicles, and if you read their specifications this should be readily apparent. Many elements in their specifications are pure speculation, and often very vague speculation. For instance, see http://www.hemisferiocriativo.com/pesquisa-nimbus.php :


Nimbus™ has a 130Kw (180hp) electrical engine lithium-ion battery powered which works simultaneously with a micro combustion generator which constantly charges the batteries. The Nimbus™ is built with very strong and lightweight materials, including carbon-fiber, titanium and aluminum, which optimizes its energy consumption (1.30 L/100 km).

Part of its careen is covered with solar panels, allowing Nimbus™ to automatically generate some of its own energy. Its regenerative brake mechanism makes Nimbus™ able to recover and save kinetic energy.



What exactly is a "micro combustion generator"? Is it a standard diesel engine, a microturbine, or something else? And exactly what kind of "regenerative brake mechanism" does the Nimbus use? Not stated. Where and how does the Nimbuse use carbon-fiber, titanium, and aluminum in its chassis and body? Again, not stated. So the Nimbus fuel consumption figure of 1.3 Liters per 100 km is purely hypothetical.

I am hoping to deliver something a bit more concrete. But, at the end of the day, mine too will be a mere "concept vehicle". But a concept vehicle that emerged out of discussion with some experienced overlanders, overlanders who are interested in what the next stage of "realistic" near-term possibilities might be.

And who are interested in some really basic questions, like, "How could you design an expedition vehicle so that it would prove easier to change big tires in the middle of the desert?" That's a question that neither Galvani nor Bekradi seems to have asked. And it's a question that only emerged in this thread, first asked by optimusprime a few pages back. It's a really, really good question to ask, as Bill Caid's website about changing tires suggests -- see http://www.billcaid.com/UnimogRepair/Wheels.html#Tires . And if an experienced trucker like optimusprime had not asked that question in this thread, frankly, it would never have occurred to me either.

As near as I can tell, neither Galvani nor Bekradi talked much with experienced overlanders. They certainly did not have conversations with thjakits about curvilinear versus rectilinear design, and the difficulty of trying to repair curved body-work in the field. Or the difficulty of trying to replace large, custom, curved sheets of glass in the middle of the jungle. Gosh, it seems they didn't even have a look at the Wothahellizat, noticing that when underway, all windows are covered.


*******************************************


So take a look at these examples of "concept expedition vehicles", Charlie, and let me know what you think. If you find them valuable, that would be interesting. But I strongly suspect that you will think these concept vehicles are a total waste of time; completely useless speculative exercises that have no connection to overlanding "reality". Nice pictures, good for a few moments of entertainment, and that's about it. Notice in particular how vague they are about very simple things, like engine placement. They both suggest that they will be range-extended hybrids, with electric hub motors, and a more conventional fuel-driven engine to top up the batteries; an engine that will be located, well, somewhere.....


ivecooexb03.jpg


Haf-E: you should take a look at these vehicles, too. What do you think? Are you inspired? Did you feel that you learned something by examining these designs? Don't they both seem a bit "La-La" land to you, too?

For instance, consider the solar array canopy that rises and fans out like a wing on the OEX-B:




Seems like a great deal of engineering and design thrown at something just so that it will "look cool". Whereas the Paradise Motorhomes expedition vehicle, with slide-outs extended, deck down, and awning above the deck extended, probably has far more available surface area for solar cell arrays:


IMG_0974.jpg 4b4-set-up-casino.jpg ge4821996057986600165.jpg
ge5047381741861201973.jpg ge5297810512694029326.jpg ext_2.jpg


Especially if the awning includes thin-film flexible solar (skip ahead about one minute into the video):




Hope these links keep you both busy for a while, and will help you to understand why I am proceeding in the way that I am.....:)

All best wishes, and Merry Christmas!

Do you think that half-tube rubber rear bumpers running around the perimeter of the back of the camper box might have mitigated the damage to LoRoad's vehicle, when he backed into a tree?

Nope. Not unless it was bolted to something more substantial than fiberglass bodywork.


But I keep finding myself thinking that Romuald Koperski covered his expedition vehicle with abundant piping for a reason, and it wasn't because he intended to enter a truck rally, flip his vehicle, or do lots of off-roading

Yea, but...if you look at some of the earlier posts you made with pics of that truck, look at the downtubes on the living cabin - they aren't fully boxed. The downtubes just end and sort of hang there. Probably tied to the frame of the box I'm sure, but still.

So all that pipework seems to me to be to really a rather fancy way of deflecting tree branches.

All well and good, but as you just said - possibly not intended to actually protect the truck from a rollover. Then again, maybe not. There is enough caging to probably at least keep the cab and cabin from fully collapsing in a rollover.

Personally, I wouldn't put too much faith in that cage setup - it looks good, but I dunno how much actual engineering went into it.

Hi dwh,

Agreed, the bumpers would have to be bolted to the rear roll cage. As you already suggested, the rear roll cage would be fully integrated with the bodywork, as per the rear roll cage in a MAN Neoplan bus, and not actually visible:


cityliner_safety_cabin_gross.jpg


And agreed, Romuald Koperski's pipework was probably intended mainly to deflect tree branches. A better engineered solution seems possible.


**************************************************


In the course of reviewing some of the OEX-B webpages that I had stored, I came across the following nugget.

One article about the OEX-B contained a hyperlink to "e-traction", a company that makes in-wheel electric hub motors: see http://www.e-traction.eu/en/ , http://www.e-traction.eu/en/company , http://www.e-traction.eu/en/products/themotion , http://www.e-traction.eu/en/references , http://www.e-traction.eu/en/references/vdl-electric-citea , http://www.e-traction.eu/en/news?start=1 , http://www.iaa.de/fileadmin/user_upload/2014/english/downloads/visitors/IAA_CV_2014_Visitorinfo.pdf , http://www.e-traction.eu/images/pdf/3 VDL BusCoach premieres at Busworld 2013.pdf , http://www.e-traction.eu/images/pdf/FD_6maart_2014_eng.pdf , http://www.e-traction.eu/en/news?start=10 , and http://www.e-traction.eu/images/pdf/ZA_Hannover_Messe.pdf :


Untitled.jpg Untitled2.jpg
Untitled3.jpg Untitled4.jpg
foto_demo_as.jpg Untitled-1.jpg


But of course there's the question about how applicable these electric hub motors would be in an expedition-vehicle context. They seem designed mainly for transit buses working in cities.

Here it would be more useful to find detailed information and schematics for the Oshkosh ProPulse diesel-electric system, and how it works in concert with TAK-4 independent suspension. A really nice, detailed image or schematic like the two just above, but for Oshkosh electric motors combined with TAK-4. Or a similar schematic from Volvo, of its Independent Suspension system designed for use not in buses, but rather, for use in heavy-duty construction or mining trucks. Campo?

And it would be good to know whether either TAK-4 or the Volvo system can "retract" wheels individually, as proposed by optimusprime, eliminating the need for a bottle jack + cribbing when changing tires or making repairs in many (but pace dwh, not all) situations.

All best wishes,

I planned on posting and discussing Hamid Bekradi's concept vehicle -- the OEX-B -- later in the thread. But because I've now mentioned it, this seems as good a time as any to explore it at length. The following is a reasonably complete set of images:

And here are the two videos again:





From these photos and videos it should be readily apparent that the OEX-B is not an expedition camper.

Rather, the OEX-B bears more resemblance to a game-watching, safari-top Toyota Landcruiser, of the kind posted earlier in the thread – see post #172 , at http://www.expeditionportal.com/for...pedition-RV-w-Rigid-Torsion-Free-Frame/page18 .

2. The OEX-B: A Futuristic Safari Bus for Short-Time-Span Game-Watching?


**************************************************


Or perhaps Hamid Bekradi's OEX-B resembles the larger kinds of game-watching buses, or mega-sized lengthened Defenders and Landcruisers, used to ferry larger groups of tourists from one safari resort to another? But buses not necessarily equipped for al fresco camping – see http://www.jenmansafaris.com/about-us/our-vehicles.html , http://www.safariafrika.biz/about-us/our-vehicles.html , http://www.jenmanvehiclecoachbuilders.com/?page_id=365 , http://www.jenmanvehiclecoachbuilders.com/?page_id=23 , http://africasafariblog.com/?p=5785 , http://www.brunosafaris.com/our_kenya_safari_vehicles_land_cruisers_and_mini_busses.htm , http://kenyantravel.co.uk/?page_id=387 , http://www.namibiatravelplan.co.uk/namibia-camping-safari.htm , http://www.namibiatravelplan.co.uk/etosha-park-tour.htm , http://www.intrepidtravel.com/za/south-africa#main-content , http://www.kruger-national-park.de/pages/english/africa-safaris/johannesburg/camping-safari.php , and http://landymag.co.za/?cat=56&page=2 :

Now if the OEX-B were indeed just a "futuristic" version of these kinds of vehicles -- vehicles mostly used for short day excursions, or excursions between resorts -- then the abundant curved glass in the OEX-B might seem "forgivable". The vehicle would never be all that far from a shop where the glass could be replaced.

But if you read the "fine print" on the OEX-B images, it is abundantly clear that Hamid Bekradi has a more ambitious target in mind:


a122506f98bf322bef3295c0818139fd.jpg


The fine print reads:

Passenger Capacity: 20
Expedition Length: 10 – 90 Days

3. The OEX-B: A Futuristic Overlanding Vehicle Intended to Replace those used by Oasis Overland, Dragoman, etc.


**************************************************


In other words, Hamid Bekradi seems to have imagined himself designing a futuristic version of the dedicated multi-passenger vehicles used by overlanding companies such as Oasis, Dragoman, Odyssey, Overlanding West Africa, and others. What follows below is a fairly full set of images of what these commercial overlanding "touristic" vehicles actually look like. When scanning through these, remember that this is the target market that Bekradi was trying to hit; but with a target date of 2020.
