A method for the continuous determination of the tension force f in a rope of a parking brake

摘要

In the method, the traction force f to a cable sleeve (2) are transmitted, which at one of a drive spindle (3) at the end facing away from (4 ") of a meander-shaped intermediate piece (4) with a magnet (5) or a magnetic sensor (6) is positioned. The meandering intermediate part (4) by the tensile force f undergoes a change in length in the direction of its longitudinal axis, which a relative movement between the magnet (5) and the magnetic sensor (6), as a result of which the signal voltage of the magnetic sensor (6) is changed. The traction force f is then determined from the respective signal voltage.
