Sensor arrangement for capturing a torque

摘要

The invention relates to a sensor arrangement (2) for capturing a torque acting on a shaft (14), wherein the sensor arrangement (2) comprises a sensor unit (4) with a sleeve (34), on which at least one sliding element and at least one first sensor which is sensitive to magnetic fields are arranged, and a magnetic-flux unit (6) with two magnetic flux-conducting rings (28, 30), wherein the at least one sliding element is arranged between the magnetic flux-conducting rings (28, 30), wherein the sensor unit and the magnetic-flux unit (6) are rotated relative to one another during a rotation of the shaft (14), and wherein the at least one sensor which is sensitive to magnetic fields captures a magnetic flux conducted by the rings (28, 30).

1. A sensor arrangement for capturing a torque which acts on a shaft having a combination of a sensor unit with a sleeve on which at least one sliding element and at least a first magnetic-field-sensitive sensor are arranged, and a magnetic flux unit with two magnetic-flux-conducting rings wherein the sensor unit and the magnetic flux unit are rotated relative to one another when the shaft rotates, and wherein the at least one magnetic-field-sensitive sensor captures a magnetic flux which is conducted by the rings, wherein, with the at least one magnetic-field-sensitive sensor, a magnetic field which changes during a rotational movement is detected and is converted into a signal which is dependent on the torque, wherein the at least one sliding element made of plastic is arranged between the magnetic-flux-conducting rings and slides radially between the magnetic-flux-conducting rings.
