    No, not in this picture. But an option. This one has electronic adjustable power to the sidecar wheel (4 positions).

    Yep, a similar idea was used on this outfit. Shaft and chain still turn all the time though. Once the wheel is locked you can only ride it off-road and it’s very hard to steer. (No differential). I don’t know what cars you have that you can lock when still driving.

    Sounds like a very good idea to me.

    Thanks for the photos Richard:clap .Quote Once the wheel is locked you can only ride it off-road and it’s very hard to steer. (No differential).Quote. :nod :nod


    Chain drive.
    I could mount the bearing housings on the center axel so i could loosen two nuts to move the complete shaft forward or back to take the chain off to disengage the sidecar wheel.
    With a axel and u joints or cv joints on the other end to the bikes wheel
    Should be easy to set up.

    Shaft drive
    both ends with axels and cv joints with the shaft in the middle held by two bearings. Use a free wheeling hub to dissengage the sidecar wheel.

    This is a few pics of a rear shaft from a quad i had sitting around, just to give you some idea of what i am trying to do.

    This is a toyota free wheeling hub set up. the top half un bolts to take the disc off . Will be easy to bolt our hub adaptor to it, for the sidecar wheel.

    [​IMG]
    I am having a look at a suzuki free wheeling hub tonight .
    Half the size of the toyota one.

    The axel for the sidecar wheel is not a problem as i am getting a
    new swingarm made so we will make it to suit the chain drive or the shaft drive.

    Hub adaptor for the sidcar wheel . This will need to be changed to suit.
    We still have two blank hub adaptors to play with.

    I think that this is sounding brilliant:clap . Leave it in 1 WD most of the time, get stuck in the sand, engage 2WD ride out and then back to 1WD. Perfect for a long desert trip with a few sandy bits - like the Simpson:evil .........

    Yes Adrian V. Simpson trip next year :deal

    I am hoping for a bit less of this. This time.

    [​IMG]

    We are doing a trip next year .
    Same as our last 8000 km trip in 2009 but a lot more dirt this time :D .
    It should be better with the 2 wheel drive set up.
    (Wife likes the idea of not having to dig or push the sidecar :sweeti )

    Simpson,finke,Tanimi road,Gibb river road , buchanan Highway,
    Carpenter Highway,Tableland Highway,Berkley Highway to Mount Isa then back home on the Diamantina road to Boulia on to Birdsville and then home.

    We have 5 weeks to do the ride . Easy:eek1

    Cheers Ian.

    Hey Pops. Not trying to be a kill joy but it seems like a lot of work for something that you may only use once or twice. I'm mean with your record of breaking things is it really worth it:lol3

    Plus with the amount of times you may use it, wouldn't it be easier to try and rig up an electric motor on the sidecar wheel that can be engaged at a push of a button (something I've been thinking of myself). Not only that isn't that what passengers are for, getting you out of bogs:D

    @ Richard-NL:

    Sounds interesting, admire the guy that pulls arround outfits that heavy around the corner if you can't make a U-turn. But the price of something like that...:puke1 Does you're ''bulldozer'' has a reverse?

    @ Pops:

    Great project! Looks like a 2wd for small money.
    Great GS you've got there! My kind of outfit!

    A nice stone could put a end to this story. Why dont they make any protection? Looks like a sidecar thats being used...

    :rofl The wife thinks the same way as you 3legs.:D

    Thanks. Great idea 3legs.The electric motor would work also. I have plenty of space under the seat. Would be easy to drive a belt from the motor to the wheel axel. It might be a pain to get the speed of the motor the same as the rear wheel .
    I think you could have some fun with this:evil :evil

    Thanks Evel Knievel. It has been a great ride so far .
    A lot more fun to ride for the wife and myself, than when the bike was solo.

    Cheers Ian.

    If twin-motor (dual-electric) drive were to be used, with the IC Motor powering a generator; then two speed controllers could have their action in variance to the position of the handlebars.

    Yet another final drive option would be to use two CVT transmissions. The variable pulley ratios should change to suit Left turn-straight ahead, and Right turn.

    We could have used 2 wheel drive on the weekend 3legs:D .

    Wife was not happy about having to walk up a few hills :evil .
    We had 40 ltrs of fuel and 20ltrs of water on board and a lot of spare parts for the lads bikes .
    [​IMG]

    [​IMG]

    But even some of the bikes had trouble getting up some of the hills.

    We are trying to buy some 4X4 Quad front half shafts to start building the 2 wheel drive setup.

    Psst. That's a Nissan Poo-troll hub. The cruiser one is a bit different to the Patrol one and a lot easier to work on IMHO. The cruiser's stupid cone washers aren't as good as the patrol's bolts but the internals are better. But if you are modding it to suit the sidecar you could could drill out the cruiser's cones and put in bigger bolts. IIRC the Suzuki has cone washers too and is very similar to the cruiser, just with a smaller axle.

    :clap You are Dead right Mickldo.:clap :clap .

    It was on my lads shed floor .
    I think it is the second one he has broke.

    I had a look at a early Suzuki lj 50 hub the other day looks good.

    I am not sure if you can get free wheel hubs for a later model suzuki.

    I am still looking :deal

    Yep, for the LJ80, Samurai (SJ410 /413) and the Jimny, free wheel hubs are available. Not really expensive either, but you will probably have to buy two of them. Solves the vacuum issue too.

    Mmmmm been a while .Well i have finally started to get things moving .
    I ended up using a 2000 model Suzuki Vitara front hub and shafts with manual free wheel hub
    Now i just have to wait untill my mate can make the center shaft for me to see if it is going to work .Then i can weld everything up .It is all bolted now just in case it don't work out .
    Still a lot to do.:deal

    This build is really coming along.
    The hub is a great idea.
    It can also be made into a type of fuse or weak link to keep from breaking more important stuff.
    The hub is easy to get to, the parts are relatively cheap and they are small enough to carry a couple of them.
    Jeep guys do this all the time to keep from blowing a differential or transmission.

    While i am waiting for my mate to do some lathe work to fit the Suzuki half shafts to the bike .
    I found a Nissan Patrol tailshaft that will do the job for a while .:wink:

    I did a small ride with it on ,works great. 100% better in the soft sand and mud .

    Ian this is excellent, simple as, how does it steer engaged?
    Not to heavy?
    I bought a viscous coupler some time ago but may or may not ever use it (realisticly speaking :D) It would negate the need for a locking hub and kick in automaticly with wheel spin.
    Am looking at getting a lathe/mill in from China if it works out in the second half of the year. Will see how it goes after that.
