Abstract
An actuator for a differential lock includes an actuator pin that is resiliently coupled to a lead screw to prevent excess force on the actuator pin under otherwise damaging conditions, such as a tooth-on-tooth state of the differential. The actuator may include sensors for sensing the position of a lead screw nut and sensors for sensing the position of the actuating pin to provide improved control by sensing multiple states of the actuator, including a state in which a tooth-on-tooth condition is present in the differential.
