  • Determination of the rotational speed of a transmission shaft
    Patent number: 7908914
    Abstract: An arrangement for determining the rotational speed of a transmission shaft (3) featuring a transmission shaft (3), a rotational speed transmitter that is connected in a rotationally fixed manner with the transmission shaft (3) and a stationary rotational, speed sensor (34), via a rotational speed that can be detected from the rotational speed transmitter. The rotational speed transmitter is provided on the periphery of a shift collar (20) of a coupling device (19) that is axially displaceable and arranged in a rotationally fixed manner on the transmission shaft. The invention also relates to a transmission with an arrangement of this kind, as well as to a method of determining the rotational speed of the transmission shaft.

  • SWITCHING DEVICE FOR A GEARGOX
    Publication number: 20090235770
    Abstract: A shift device (13) for a manual transmission having actuation mechanisms for shifting and selecting in which the selection motion is carried out by way of a selector actuator (10), which is connected to a driving lug (5) of a selector plate (4). An anchor (1) of the selector actuator (10) consists of a permanent magnet (2). End stops (3) of the selector actuator (10) are configured of ferromagnetic material, where the anchor (1) of the selector actuator (10) is fixed in a defined position for the installation of the selector actuator (10).
