torquebiasing

Torquebiasing is a system used in automotive differentials to enhance traction. It's a type of limited-slip differential that can automatically transfer torque to the wheel with more grip. When one wheel begins to lose traction, such as on a slippery surface, the torquebiasing differential detects this difference in rotational speed. It then uses internal mechanisms, often employing clutches or viscous fluids, to create resistance. This resistance directs a greater portion of the engine's torque to the wheel that still has traction. This process helps prevent wheelspin and allows the vehicle to maintain forward momentum. Torquebiasing differentials are a compromise between an open differential, which offers no torque transfer, and a locking differential, which rigidly connects both wheels. They provide a significant improvement in traction without the harshness or handling drawbacks sometimes associated with a fully locked differential. The amount of torque bias can vary depending on the specific design and application.
