Re: Lockers? Well thinking about them..but?
Well, Tim, not to put too fine a point on it, you posted that the wheel with the least traction gets 100% of the power in your first post reply. This is true when one wheel has zero traction. When one wheel has lets say 20% more traction than the other, the one with the less traction gets more power, to be sure, but the high traction one still receives some power. In the turn, the outside wheel gets more but the inside gets some, not none.
Where both tires have no traction, then both will get 50% of the available power to the axle because the differential only reacts to the relative resistance between the two wheels. Since both are zero (in this case) each tire receives an equal amount of power, just as they would if the vehicle were traveling straight down the road with a good grip in each tire. This is the reason that 4wd part time high can be dangerous on icy roads; the zero traction in each tire of the axle will cause each to spin equally and that will cause the rear (or front) of the vehicle to slide sideways. This is also true of a fully locked driveline, namely a locker and a locked up transfercase. This is why a center open transfercase (full time 4wd) is safer to drive on icy surfaces and a fully open system (t'case plus axles) are best for safe icy travel.[img]images/icons/smile.gif[/img]
