Differential system - different directions 1

[MoHabib]

Hello,
I am Habib from Egypt.
I'm trying to build an agriculture machine for compost industry and nowadays I'm searching about a concept for a differential system that allows the machine's wheels to rotate in different directions, one of the wheels rotate to the front and the second to the rear.

Is this possible to find a system like this or to edit to an existing system?

I think EVERY non-limited slip differential system allows for opposite rotation. The key words are "non-limited slip". Limited slip differentials have some sort of system that prevents EXCESSIVE differences in rotation.

But it is possible that you are having trouble expressing exactly what you want the differential to do - like put POWER to the ground so the machine can turn within its own footprint - and in that case, I suspect that the problem is one of steering, not the differential. Look up lawn mowers with a zero turning radius.

I've personally never heard of such a differential. I suppose one could theoretically be designed, but - for zero turning circle applications, most equipment I've worked with uses hydraulic motors for driving the wheels. Look at the way a Bobcat (skid steer loader) operates, for example.
The hydraulic motors are much easier to set up to do this, and since you're presumably already fitting a hydraulic pump for the rest of the machine...

Differentials do allow wheels to turn independently but the torque of both wheels is always in the same direction. It seems that you want to be able to select the direction of torque to each wheel, for a zero turn radius. A differential cannot do that, but if you apply a brake to one wheel the other wheel will turn faster, and the axle will pivot around the braked wheel, which is close to what you want to do. Farm tractors sometimes have independent left and right brakes. It is called brake steering. But for this to be effective you need a tracked vehicle or casters for the other wheels.

You probably should delete, or request deletion of the double post over in Transmission and driveline, and any where else.
