Abstract
A method and a device (1) are provided for determining a torque of a transmission, in particular of an actuating drive (14), in which an elastically deformable bending element (4) that deforms as a function of the torque is arranged in a transmission path of the torque, and a sensor unit (8) with which deformation of the bending element can be detected forms a structural unit which can be mounted as a whole.

A method for determining a torque of a transmission for an actuating drive (14), the method comprising:
- arranging an elastically deformable bending element (4), which deforms as a function of the torque, in a transmission path of the torque;
- and
- detecting a degree of deformation using a distance measurement with a Hall sensor (13);
- wherein the bending element is formed as a tongue in a plate-shaped carrier, and a first transmission stage of the transmission is attached to the carrier and a second transmission stage of the transmission is attached to the bending element.
A device (1) for determining a torque of a transmission of an actuating drive (14), the device comprising:
- a base plate (2);
- an elastically deformable bending element configured to deform as a function of the torque arranged in a transmission path of the torque, wherein the bending element (4) is formed as a tongue in a plane of the base plate (2), and the deflection of the bending element (4) occurs in the plane of the base plate (2);
- and
- a sensor unit (8) configured to detect a deformation of the bending element that forms a structural unit with the elastically deformable bending element that can be mounted as a whole.
A device (1) for determining a torque of a transmission, the device comprising:
- at least two elastically deformable bending elements (4) which can be deflected essentially tangentially with respect to a rotational direction of the transmission, the bending elements being adapted to be attached to a fixed part of the transmission;
- a sensor unit (8) configured to determine a deflection of at least one of the bending elements (4);
- and
- a base plate (2), and the bending elements (4) are formed as tongues in a plane of the plate, and the deflection of the bending elements (4) occurs in the plane of the plate.
