Wireless system for determining displacement of spinning components
First Claim
1. A wireless system for determining the displacement of spinning components of a differential assembly, comprising:
- a differential case having a hollow interior space;
the differential assembly including an actuator including an electromagnet having a coil and 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,wherein the differential case houses the differential gear arrangement,wherein a portion of the sensor assembly extends axially and radially within the differential case and the at least one sensor is positioned axially adjacent to the spinning component of the differential assembly in the hollow interior space of the differential case,wherein the at least one sensor directly senses the axial displacement of the spinning component,wherein the sensor assembly generates a signal representing the axial displacement of the spinning component, andwherein the transmitter is wirelessly coupled to a receiver positioned outside the differential case.

Abstract
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.
