Abstract:
1. A sensor device for the detection of the lining wear at a disc brake having a brake caliper and a brake actuation mechanism being arranged in the brake caliper, which comprises a thrust piece which cooperates directly or indirectly with a brake lining so that the movement of the brake lining corresponds to the movement of the thrust piece, wherein the sensor device can be inserted as a unit into an interior of the housing of the brake caliper from the rear and freely traverses the interior of the housing of the brake caliper up to the thrust piece, wherein the sensor device comprises a transmitting element for transmitting the linear movement of the thrust piece into a rotational movement and a sensor element for detecting the rotational movement, in which the transmitting element comprises a linear element attaching to the thrust piece which is displaceably arranged relative to a threaded element, which is stationary, but rotatably supported, in which the threaded element will be set into rotation upon displacement of the linear element and in which the threaded element at its end facing away from the brake disc cooperates with the sensor element in a touchless manner.
