Eek This picture got me thinking, Front wheel drive Hack

I know almost nothing about sidecars so i'm sorry if this is just a stupid idea, but a front wheel drive Hacks makes kind of sense to me.



Maybe a three wheel drive will be the ultimate snow machine.

Such as using THIS for a front & rear drive combination tug?

In 2008 - The addition of front suspension:
Quote:
How it works: The driven front suspension is a leading link type. It has the advantage of low weight and lower unsprung weight which improves traction. It is stiff horizontally which allows the use of one light weight spring shock unit and allows for 8 inches of shock travel. It consists of a swing arm pivoted at the bottom of the front fork. A dual idler sprocket rotating at this pivot point receives the drive chain from the front drive miter box. A second chain on this dual idler sprocket drives the front wheel. Both chain drives thereby have constant sprocket center distances.

Actually From what i can see this guys used a different trick, somehow popular in the "Rockcrawler" community.

The comcept is actually pretty simple, they take a small "Transverse" engine and tranny (from a front wheel drive car) mount it longitudinal behind the driver seat (center of mass of the vehicle) and use one of the half shafts (left or right depends in how the engine and output shaft spines) to send power to a rear differential (Actually a "Locker") and do the same for the front wheels, ending up with a 4 wheel drive vehicle.

Notice how the "Motorcycle" is moved to the left side of the driveline and the substantial "Box" structure where the shafts will be house.


At least that is how it looks (To me) from the pictures Richard post.

Also Notice the "3x3" sticker in the back of the chair. (I think that is what it is)

It is a Vogel 3 wheel drive made in France. I am thinking may be it's made from parts of, or a modify 4X4 ATV

HEY!!! Someone has been peeking at my design boards!!!

Seriously, I have been working on some sketches and early layouts of a design for a 2-wheel or 3-wheel-drive sidecar where the sidecar frame is used to hang all three wheels/suspensions off of.

My powerplant of choice, of course, was going to be an oilhead boxer BMW. And I see that they this Vogel rig has already been mated to an Airhead.

The frame looks to me to be all custom fabrication, and the hubs/axles look like automotive front-wheel-drive half-shaft units. Smart-Car perhaps???



Cannot seem to find many other photos or details about the rigs. The builder is listed on several websites listing sidecar manufacturers in France, but there is no website or email address for them, and they all date back to 2007.

Are they still around???

I think I have a interesting question..

How about just running A-arms mount from the main frame to the wheels, Front and maybe even the tub wheel with steering and the rear one fix straight...??

Sounds kind of logical to me since all the power stems from the massive rigid frame already.

Please tell me what you guys think.

Do you mean like this???





High/Low range chaincase, reversing gearbox, and a viscous coupling to allow differential rotation between the two drive axles.

Mobec Superdrive from Germany...

Simpler version of a Mobec 2-wheel-drive unit.



Direct drive out of the BMW final drive, no reverse, no high/low range, but does have viscous coupling to allow differential rotation of wheels while cornering.

Aluminum box is a 1:1 chain-case to transfer power forward, allowing for proper sidecar wheel lead.

Oh Yeah that is exactly what I'm taking about, actually even farder than I spect it.

I just hate to ask how many bundles of $40,000 bills such a beauty is going to cost.

Thanks for posting.

Now for one more challenge..

Why does the engine need to be in the conventional location if you are making a sidecar specific chassis including the "Motorcycle frame"

Refer to Bob Pelican super wonderful Wanker power yellow monster that he name "Roto Hack" for example


Sure if you have a set up like this in the dirt, you will spend the whole time looking at stars not only do to the power but the vias center of mass.

Here is their web site;
http://www.mobec-international.com/index2.php

I got some prices from them a couple of years ago.

As the saying goes,"if You have to ask, You cant afford it". Over $16K for their most basic unit. +bike +bike mods +tub +frame +paint +lights +++++

If I ever win the lottery.......

Mobec also makes a 2WD conversion for the KTM 950 Adv. It's listed on their site anyway. I contacted them awhile back about buying the parts to convert my 950. They wanted $30,000+ and needed me to ship my 950 to Germany. Apparently, it's not a bolt-on!

I'd love to buy the parts. Not happening!
