Magnetic track brake having a high-position detecting means installed in or on the actuation cylinder

A magnetic track brake apparatus for a rail vehicle, the apparatus comprising:

• at least one pressure-medium-actuated actuation cylinder which has a cylinder housing and an actuating piston movable relative to the cylinder housing;
• at least one magnet device which can be lowered into a low position onto a rail by the at least one actuation cylinder to generate a magnetic attraction force between the rail and the at least one magnet device by a magnetic short-circuit with the rail, and which can be placed, by the actuation cylinder, into a high position raised from the rail and into any intermediate positions between the low position and the high position;
• and
• at least one high-position detecting device which generates a high-position signal when the at least one magnet device assumes the high position,
• wherein the high-position detecting device has a structural unit which is separate from the at least one actuation cylinder and is releasably attached to the cylinder housing of the at least one actuation cylinder by a fastening device, and at least one electrical limit switch which is arranged inside a housing of the high-position detecting device and has least two switch states,
• wherein the limit switch has an actuating element which can be placed into at least two different positions and, on movement of the actuating element between the at least two different positions, the switch state of the limit switch changes between the at least two switch states, and
• wherein the structural unit has at least one actuator element which is movable on or in the housing such that the actuator element changes its position relative to the housing depending on the vertical position of the at least one magnet device, and hence exerts an influence on the position of the actuating element of the limit switch.
