Sensor system for combined speed-torque detection

摘要

A sensor system having at least two phase tracks spaced apart in the axial direction of a rotation axis of a rotating body and situated circumferentially around it, having at least one sensor element for each phase track situated fixed in place opposite the rotating body to detect the particular phase track. At least one first sensor element assigned to a first phase track, with at least one second sensor element assigned to the first phase track, is connected to at least one first sensor element bridge, extending parallel to the first phase track and perpendicularly to the rotation axis of the rotating body, and at least one sensor element assigned to a second phase track, with at least one sensor element assigned to the first phase track, is connected to at least one second sensor element bridge extending perpendicularly to the two phase tracks and parallel to the axis.

1. A sensor system, comprising:
a first phase track; a second phase track spaced a distance apart from the first phase track in an axial direction of a rotation axis of a rotating body; a first pair of sensor elements that at least one of is assigned to and detects the first phase track and is situated fixed in place opposite the rotating body, the first pair including a first sensor element and a second sensor element; a third sensor element that at least one of is assigned to and detects the second phase track and is situated fixed in place opposite the rotating body; a first sensor element bridge that connects the first pair of sensor elements; a second sensor element bridge that connects one of the first pair of sensor elements and the third sensor element; wherein:
the first phase track and the second phase track are situated circumferentially around the rotating body;the first sensor element bridge is situated parallel to the first phase track and perpendicular to the rotation axis of the rotating body in a top view; andthe second sensor element bridge extends transversely to the first and second phase tracks in a top view.
