Der Erfindung liegt die Aufgabe zu Grunde, ein gegenüber dem Stand der Technik verbessertes Bremssystem für ein Fahrzeug anzugeben.The invention is based on the object of specifying a brake system for a vehicle that is improved over the prior art.
Die Aufgabe wird erfindungsgemäß gelöst durch ein Bremssystem, welches die im Anspruch 1 angegebenen Merkmale aufweist.The object is achieved according to the invention by a brake system which has the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous refinements of the invention are the subject matter of the subclaims.
Ein Bremssystem für ein Fahrzeug umfasst zumindest einen hydraulischen Bremskreis, zumindest eine Bremsscheibe und mittels eines in dem hydraulischen Bremskreis geführten Mediums hydraulisch betätigbare Bremsbeläge.A brake system for a vehicle comprises at least one hydraulic brake circuit, at least one brake disc and brake linings that can be hydraulically actuated by means of a medium guided in the hydraulic brake circuit.
Erfindungsgemäß ist ein Notbremskolben vorgesehen, wobei der Notbremskolben unabhängig vom hydraulischen Bremskreis aus einer Nichtgebrauchsstellung in eine Gebrauchsstellung überführbar ist. In der Nichtgebrauchsstellung gibt der Notbremskolben eine Bewegung der Bremsscheibe frei und in der Gebrauchsstellung hemmt er die Bewegung zumindest.According to the invention, an emergency brake piston is provided, the emergency brake piston being able to be moved from a non-use position into a use position independently of the hydraulic brake circuit. In the non-use position, the emergency brake piston releases a movement of the brake disc and in the use position it at least inhibits the movement.
Kommt es im Fall eines Unfalls zu Undichtigkeiten in einem hydraulischen Bremssystem, kann es zu einem Abfall eines Hydraulikdrucks in einem Bremszylinder und damit zu einer verringerten oder nicht mehr vorhandenen Anpresskraft der Bremsbeläge an die Bremsscheibe kommen. Im Fall eines Unfalls ist es jedoch wichtig, ein sicheres Abstellen des Fahrzeugs durch Fixierung der Bremsen zu realisieren, um weitere Gefährdungen für Fahrzeuginsassen, Rettungskräfte und andere Verkehrsteilnehmer zu vermeiden.If, in the event of an accident, there is a leak in a hydraulic brake system, the hydraulic pressure in a brake cylinder may drop and the contact pressure between the brake linings and the brake disc may be reduced or no longer present. In the event of an accident, however, it is important to ensure that the vehicle can be parked safely by fixing the brakes in order to avoid further hazards for vehicle occupants, rescue workers and other road users.
Mittels des vorliegenden Bremssystems und des Notfallbremskolbens kann eine unabhängig vom hydraulischen Bremskreis und somit unabhängig vom Hydraulikdruck sicher wirkende Bremswirkung mit Haltefunktion erzielt werden. Somit kann eine schnell wirkende Notfall-Feststellbremsfunktion zur Einhaltung künftiger Crashanforderungen realisiert werden.By means of the present brake system and the emergency brake piston, it is possible to achieve a braking effect with a holding function that acts reliably independently of the hydraulic brake circuit and thus independently of the hydraulic pressure. A fast-acting emergency parking brake function can thus be implemented to meet future crash requirements.
Beispielsweise kann eine Auslösung der mittels des Notfallbremskolbens ausgeführten Bremsfunktion auch bei Erfassung eines versuchten Diebstahls des Fahrzeugs bei Auslösung einer Diebstahlwarnanlage erfolgen. Hierdurch kann eine Gefahr einer Entwendung des Fahrzeugs signifikant verringert werden.For example, the braking function carried out by means of the emergency brake piston can also be triggered when an attempted theft of the vehicle is detected when a theft alarm system is triggered. This can significantly reduce the risk of the vehicle being stolen.
