Title: SENSOR DEVICE FOR A CENTRAL CLUTCH RELEASE MEANS, CENTRAL CLUTCH RELEASE MEANS, AND METHOD FOR OPERATING THE SENSOR DEVICE
Abstract:
The invention relates to a sensor device (1) for a central clutch release means (2), comprising a first displacement sensor (13) which is arranged on the radially outer circumference of the release means (2) for detecting the position of an axially movable release means (2) component (3); a first signal transmitter (15) which is connected to the movable component (3); and a first signal receiver (16) which is connected to a stationary component (4) of the release means, is arranged radially over the first signal transmitter, and is operatively connected to said signal transmitter. The first signal transmitter can be moved linearly together with the movable component (3) along a longitudinal axis of the first signal receiver (16). Furthermore, a second displacement sensor (14) is arranged on the release means (2) diametrically opposed to the first displacement sensor (13); the second displacement sensor (14) has a second signal transmitter (17) which is connected to the movable component (3); the second displacement sensor has a second signal receiver (18) which is connected to the stationary component (4) of the release means, is arranged radially over the second signal transmitter, and is operatively connected to said signal transmitter; the second signal transmitter can be moved linearly together with the movable component (3) along a longitudinal axis of the second signal receiver (18); the sensor device has an electronic analysis unit (19) which is connected to the two displacement sensors for signaling purposes; and the electronic analysis unit is designed in such a manner that the output signals of the two displacement sensors can be linked by means of the electronic analysis unit such that the axial position of the movable component (3) can be determined therefrom.
