<p>A sensing system for sensing the drive torque applied to a vehicle wheel end assembly (100). The sensor system (200) is integrated into the internal spaces of the bearing assembly (103) within vehicle wheel end assembly (100), and is protected from environmental conditions. The sensor system (200) incorporates a pair of spaced-apart sensing elements (202a, 202b) disposed on a stationary member (104) of the vehicle wheel end assembly (100) in alignment with the axis or rotation. A target element (300) disposed on the rotating member (102) of the vehicle wheel end assembly (100). Each sensing element (202a, 202b) generates a signal which is responsive to the passage of the target element (300), at a frequency which is proportional to the rotational speed of the wheel end assembly (100). Torsional twist of the rotating wheel end hub member (102) resulting from the application of a drive torque is registered as a phase shift between the signal output from each of the sensing elements (202a, 202b) which can be monitored as a measure of the drive torque applied to the vehicle wheel end assembly (100).</p> |
