Abstract
A method for detecting a state of a brake, a brake and a brake system having such a brake, wherein an action element of a brake actuator is moved in a direction in which a friction element connected to the action element is moved in a direction of action towards an element to be braked; wherein, as a first key position, a position of the action element is detected, in which, by an increase in force, a contacting of the friction element on the element to be braked is identified.

A method for detecting a state of a brake for a rail vehicle, the method comprising:
- moving an active member of a brake actuator in a direction, in which a friction element which is connected to the active member is moved in an active direction toward an element to be braked;
- and
- detecting, as a first corner position, a position of the active member, in which the friction element bearing against the element to be braked is detected by a rise in force beginning.
A brake for a rail vehicle, the brake comprising:
- a brake actuator;
- a friction element;
- an element to be braked;
- and
- a brake mechanism, which has the brake actuator, and which is configured to:
- move the friction element for a brake operation in an active direction toward the element to be braked in a manner which is dependent on a movement of an active member of the brake actuator, and
- move the friction element away from the element to be braked counter to the active direction in order to end the brake operation,
- wherein the brake mechanism is configured to detect a force, exerted on the friction element along the active direction, and
- wherein the brake mechanism is configured to detect a position of the friction element along the active direction by a force, exerted on an active member of the brake mechanism, and a position of the active member.
A brake system comprising:
- a brake including a brake actuator, a friction element, an element to be braked, and a brake mechanism, which has the brake actuator, and which is configured to:
- move the friction element for a brake operation in an active direction toward the element to be braked in a manner which is dependent on a movement of an active member of the brake actuator, and
- move the friction element away from the element to be braked counter to the active direction in order to end the brake operation,
- wherein the brake mechanism is configured to detect a force, exerted on the friction element along the active direction, and
- wherein the brake mechanism is configured to detect a position of the friction element along the active direction by a force, exerted on an active member of the brake mechanism, and a position of the active member,
- wherein the brake mechanism is configured to detect a state of a brake for a rail vehicle by:
- moving the active member of the brake actuator in a direction, in which the friction element which is connected to the active member is moved in the active direction toward the element to be braked;
- and
- detecting, as a first corner position, a position of the active member, in which the friction element bearing against the element to be braked is detected by a rise in force beginning,
- continuing the movement of the active member and the friction element connected thereto in the active direction to produce a brake operation,
- moving the active member and the friction element connected thereto counter to the active direction to end the brake operation,
- detecting, as a second corner position, a position of the active member, in which the lifting of the friction element from the element to be braked is detected by a decrease in force ending;
- and
- a control apparatus configured to actuate the brake and configured to evaluate and to process the detected first corner position and the second corner position.
