| 摘要 |
The present invention relates to a device for determining the rotational speed of a transmission shaft (12), comprising a rotational speed transmitter (3) that is rotationally fixed to the transmission shaft (12), and at least one rotational speed sensor (2) with at least one sensor element (10). By means of the sensor element (10) the rotational speed of the transmission shaft (12) can engage with the rotational speed transmitter (3). According to the invention, the rotational speed sensor (2) is mounted on a shifting element (5) for the purpose of actuating a sliding sleeve (4) of a transmission device (1), said sliding sleeve being axially movable on the transmission shaft (12) and being connected to the transmission shaft (12) in a rotationally secured fashion. |
