Abstract:
1. A device for determining a steering angle and a torque exerted on a shaft, the shaft having a first shaft section and a second shaft section, which can rotate relative to the first shaft section, the device comprising: a first multi-pole magnetic ring disposed to surround the first shaft section and to cooperate therewith; a stator holder mounted to the second shaft section; a first stator element mounted to said stator holder, said first stator element having first fingers which project outwardly in an axial or radial direction and which are distributed substantially uniformly about at least a portion of a periphery of said first stator element, said first fingers defining interposed first gaps, wherein said first fingers communicate with said first magnetic ring; a second stator element mounted to said stator holder, said second stator element having second fingers which project outwardly in an axial or radial direction and which are distributed substantially uniformly about at least a portion of a periphery of said second stator element, said second fingers defining interposed second gaps, wherein said second fingers communicate with said first magnetic ring; a second magnetic ring disposed on one of the first and the second shaft sections; and at least one magnetic sensor communicating with said second magnetic ring.
