Abstract
A clutch system is described wherein a two-way roller clutch system transmits torque in from one direction (i.e., input side) only, and allows the clutch system to be physically decoupled from the power steering system when torque is forced in from the output side, e.g., during loss of electrical power to the power steering motor. Additionally, the clutch system can include a torque limiting system that permits slip when overall torque exceeds a preset limit. Both the clutch system and the torque limitation system are especially useful in conjunction with automotive power steering systems.
