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.
