Abstract

A sensor arrangement for indirect detection of a torque of a rotatably mounted shaft includes a sensor with at least one sensor element arranged in the surroundings of a bearing of the shaft. The bearing is linked to a supporting structure. The sensor element is configured to detect a proportion of a bearing force acting in a predetermined direction. The torque of the shaft is configured to be calculated from the acting proportion of the bearing force. The sensor has at least one sensor body with an outer contour that supports a corresponding sensor element and is pressed into a receiving hole. The sensor element has a predetermined distance and a predetermined angle to the bearing.
