Detroit locker style rear axle?

It seems like driving both rear wheels would be an advantage on dirt, but a locked axle induces all sorts of issues on pavement. Driving both rear wheels through roller clutch bearings (readily available in a range of sizes) seems like it would be a good compromise. Anyone tried this?

Can't brake on the axle. And you're still driving both wheels equal under power no?

Yep, you'd need to put brakes on the wheels.

Both wheels would drive, but on pavement the outside wheel could roll faster than the inside one on turns, so you wouldn't have the tires skidding. Ever tried to drive a locked diff on pavement?

Roller clutches wouldn't be as good as a real diff, but way lighter and simpler.

I guess the inside wheel would be forced to lag. Wouldn't be that much work to brake an ATV hub.
To bad these things don't like front brakes, but apparently the steering goes away, so they say.
But "they say" alot of things. I've never tried it.

I don't know what "Roller Clutches" are???
But, I have installed a Northern Tool Diff in my CK and have installed brake rotors on each axle.

Timken makes them. They're called clutch release bearings. They lock one way, roll free the other.

I believe you're thinking about one-way bearings Scot. Some
manufacturers do call them clutch or one-way/clutch bearings.
I looked into those about a year ago but lacking any engineering
skills or a variety of bearings to play or experiment with I shelved
the idea. I don't see why they wouldn't work, if you could figure out
what size you would need to take the torque.
I believe you could make the rear axle a much lighter set up than the
Peerless 100 differential which is not a locker.
The down side is, since they are "one-way" you would loose any
braking from the engine. They become a coaster when torque is
applied in the reverse direction, so you would have to have some
dang good brakes doing all the work.
But as far as brakes are concerned, I was planning on running dual
discs anyway since there seems to be so much trouble with the
single set up. But... I'm also planning on running a larger (301cc)
engine in my cart since I'm not planning on participating in any
organized events.

We eat late!
Tomorrow is a travel day so I worked on the Stude today.
We will be in the USA fort the next week at a Rod Run!
Hope to hook up with Randy to check out his progression second CK.

It would be a lot of work to make these work,they are open bearings so dirt wil come in and grease go out so you have to make seals,and how about side impact? I don't think they can handle that.

Bout a good 1000 miles one way Woody. Much to far for an afternoon CK ride.

Those are available as a sealed bearing Rene, but the cost gets to be outrageous.
No such thing as a perfect solution.
We just keep coming back to the "keep it simple" formula that Pete & Mike
Stevenson arrived at after their searches.

Hello guys,

In France we call for "freewheeling" like the pedaling of bicycles ..
For a while, I thought about this solution ! But I did not know which wheel "accelerates" and which wheel "slows down" ??
Actually I thought: if the inner wheel slows down, everything is ok, the "freewheel" bearing is working properly, But if it is the outer wheel that "accelerates" the "freewheel" bearing can not work properly
This reasoning is probably a bit "bizarre" So I stopped this project to start another type of differential ...

Fabrice, were you able to figure out what size "freewheeling" bearing you
would need to handle the torque from an 8 to 10 hp motor that was geared
down 5:1 or 6:1????

Hi Denny,

No I do not know ! It is for this reason that I had studied the idea with 4 free wheels if 2 are too fragile ....
