That is one of the best ideas I have heard. The issue of balancing
such a carefully made and rugged/heavy assembly would be a mechanical
design engineer's job all right.
How about a two piece interaxle shaft which has a central axle inside
it, fixed into to the front half, and free to spin in the rear half as
with a pilot bearing, and two halves of a large dog clutch, one fixed
on the front half and one sliding on external splines on the on the
back half of this interaxle shaft. Lock by sliding the rear half of
the dog clutch to the front, unlock by sliding it back? The only
question is how to match up the dogs if they are out of sync when you
have stopped and are crawling under the truck to do this. Lockout hubs
seem to have some kind of spring action which helps them work once you
have set them. i don't know how it would work with a shaft.
Has anyone ever made such a thing?
