Heck this would make such a big difference in traction!

Whenever the vehicle gets stuck.. the tire with the most traction would get the power. wouldnt that rock?
Then we can power thru sand and mud like its nothing

I know its complex to implement.. but just an idea!

Ram,
Great idea, although not exclusively yours. That idea (for R/C cars) has been around for a long time. Do you have any ideas on how it would be done? I devised one for my Nitro Rush. It utilizes friction disks and springs just like the full sized ones. Do some research on automotive limited-slip-differentials and maybe you will come up with a simple workable device for R/C vehicles. The only one that I know of at this time is the Torsen Diff. It is expensive, complex, and will only fit a few car/trucks.

Well my only complaint is that like LSDs from real cars, these will wear out EASILY if we use the same manufacturing techniques as real cars.. they would have to be made exclusively out of titanium/Carbon fiber or something high grade like that.

A viscous clutch plate type would be cool but this stuff will rob some power!
Maybe a tubular spring loaded clutch would do the trick? lol
I think I'm gonna fool around with this and try to make me one and mod my mugen
That would kick ass!
In the mean time I'm gonna go do more research.. my friend is gonna buy one for his 240SX.. I'll see if I can open it up

KRUSTY: Can you post any pics of what you have?

Differential grease.I dont know excactly how it works.
Crash can probably explain it better than I can.
Crash?

Hmmm....So it's traction that you want, eh?

It appears that you can add grease to your diff to help with the traction department.....but it's not achieving what your talking about Ram....not entirely. Here's a couple of links to check out on adding diff grease:

BoneZ'.....How you been?

Looking at the title.. $2? I'm there! lol

Well still talks about changing the way an open diff works. But its still an open diff that transfers traction the the wheel with the LEST traction.

I'm trying to get power to the wheel with the MOST traction!
I'm trying to get a look at some of GM's dry difffs.. maybe they can gimme a hint!

and thanks for the links Cary!

Open differential = diff that use small spider gears. No oil or anything on it. run freely.

Limited slip differential = same as open diff but with heavy silicone oil. There a whole range of diff silicone oil to fine tune the diff action

Locked diff = open diff that has completly locked either with the most heavy weight silicone diff you can find or even resin or glue. Will act as a solid axle.

Ball diff = small carbide balls are used, it act exactly as an open diff except that there is no need for silicone diff, it's way easier to fine tune the action

torsen diff = complete different design that allows to trasfer the power to the more traction wheel.

Ex: Ofna torsen diff used on buggies:



Very effective, very expensive, used mainly as option in high end buggies. Involve very difficult to machine special gears.

Hope this help

I wonder if anyone could make a miniature version of a Detroit Locker. Could you make one that small? Or maybe the ARB air locker? Use your third channel to engage/disengage. Now that would be cool.

A word of caution. Stay away from spools. They are hard on the drivetrain. My friend put one in his T-Maxx and wasted a set of MIP CVDs in no time.

Damn frenchies.. exquisite.. refined and expensive
HEHE just kiddin.. Thanks for the the info! That looks great!

Now I wanna know how it works!
Anyone have a link? I wanna know exactly how a torsen and a limited slip works
thanks

Put a seperate brake on each rear wheel(by the way,this would be REALLY impractical and hard to do)and hook the levers to the brakes to a servo with a brake cable on each side of the servo horn using a 3 channel radio,and when one wheel lost traction,lock up one wheel and it would have to send all the power to the other side.But again,this would be really impractical and hard.

make yourself a mini torque converter,
that would be strange, but would work, i think

BUGGIES_R_US

torque convertor? EWW next thing you know were gonna have friggin synchro mesh trannies in these things! lol
