Abstract
A driveshaft assembly that includes a first shaft member, a second shaft member, a bearing assembly and a sensor. The first shaft member has a magnetically encoded zone with a magnetic field that varies as a function of the torque that is transmitted through the first shaft member. The second shaft member is coupled for rotation with the first shaft member. The bearing assembly comprises a bearing support, which is configured to be coupled to a vehicle structure, and a bearing that is housed in the bearing support. The bearing journally supports the first shaft member for rotation about a first axis. The sensor is coupled to the bearing assembly. The sensor is arranged to sense the magnetic field of the magnetically encoded zone and responsively produce an electrical signal.
