Lift a wheel (or substantially unload a wheel) and you get zero axle-load on that side - that means that during the time the wheel is unloaded, the typical diff will NOT power the wheel that"s still on the ground. The problem is that when one tire has LITTLE or NO grip (zero axle-load), the other wheel gets ZERO DRIVE, because (basic math here): 2.5 x 0 = 0. This is a significant improvement over an open diff most of the time. For example, if a diff has a bias ratio of 2.5:1, then it can apply drive torque to the wheel with the most traction (gripping wheel) at 2.5 times the traction limit of the wheel with the least traction (slipping wheel). Torque biasing differentials offer increased bias ratios over open differentials. All your power goes out the slipping wheel - along the path of least resistance. When one wheel loses grip, the total available drive is lost as well (at a 1:1 ratio). They can only apply as much drive torque as there is available traction at one wheel. Standard, open differentials have a bias ratio of 1:1. The amount of drive torque one wheel can get over the other is described as the bias ratio, a measure of the torque split across the axle. It also occurs during the transition from engine driving a vehicle to engine braking and back, even with both drive wheels firmly on the ground.ġ) If you lift a wheel, all gear diffs except Wavetracåâ, will NOT power the other wheel.Ģ) During the transition from accel to decel, all gear diffs except Wavetracåâ, do nothing.Īll gear LSDs (including Torsenåâ, Truetracåâ, Quaifeåâ, Peloquin, OBX, etc.) work in basically the same manner: they divide the drive torque between the two axles, applying drive to each side, up to the available grip of each tire. Zero or near-zero axle-load is the condition that exists when there is "åno-load" applied through the drivetrain, when one drive wheel is nearly or completely lifted (often in aggressive cornering). Zero axle-load is a condition that occurs during normal driving, but creates the most noticeable problems when driving in extreme conditions. The problem: Loss of drive during zero or near-zero axle-load conditions. To best understand how the Wavetracåâ is truly different from the other gear differentials on the market, you first have to understand the primary problem that the Wavetrac solves. The Wavetracåâ differential will perform a lifetime of service with no maintenance or rebuilds. ARPåâ fastening hardware used throughout.
