摘要：
A wireless system for determining the displacement of spinning components of a differential assembly, including a differential case having a hollow interior space; a differential assembly having an actuator including an electromagnet having a coil, a spinning component selectively engaged with a differential gear arrangement and at least one sensor assembly non-rotatably mounted to the differential case including at least one sensor communicatively coupled to a printed circuit board, a transmitter and a power source. The sensor assembly extends axially and radially within the differential case and at least one sensor is-configured to directly sense the axial displacement of the spinning component and the sensor assembly is configured generate a signal representing the axial displacement of the spinning component into a signal that is wirelessly transmitted to a receiver positioned outside the differential case.
