Abstract
Description
Stand der TechnikState of technology
Die vorliegende Erfindung betrifft eine Feststellbremse für ein Fahrzeug zur Realisierung einer automatisierten Feststellbremse (Parkbremse).The The present invention relates to a parking brake for a vehicle for the realization of an automated parking brake (parking brake).
Feststellbremsen sind aus dem Stand der Technik in unterschiedlichen Ausgestaltungen bekannt. Konventionelle Feststellbremsen werden über einen Handbremshebel und einen Seilzug aktiviert. Um auf den Handbremshebel verzichten zu können, sind in jüngster Zeit sog. automatisierte Feststellbremsen vorgeschlagen worden, welche anstelle des Handbremshebels einen über einen Knopf oder Schalter aktivierbaren Elektromotor aufweisen, welcher an dem Seilzug der Feststellbremse zieht. Mit derartigen Systemen kann insbesondere der Bauaufwand im Fahrzeug für die Feststellbremse reduziert werden. Um eine sichere Feststellung zu ermöglichen, muss jedoch der Elektromotor entsprechend dimensioniert sein, was zu relativ großen Abmessungen des Elektromotors führt. Es wäre daher wünschenswert, eine verbesserte und kompaktere Feststellbremse bereitzustellen.Parking brakes are of the prior art in different configurations known. Conventional parking brakes are via a handbrake lever and activated a cable. To renounce the handbrake lever can, are in the most recent Time so-called automated parking brakes have been proposed which instead of the handbrake lever on a button or switch have activatable electric motor, which on the cable of the Parking brake pulls. In particular, with such systems the construction work in the vehicle for the parking brake can be reduced. To be sure to enable However, the electric motor must be dimensioned accordingly, which to relatively large Dimensions of the electric motor leads. It would be therefore desirable to provide an improved and more compact parking brake.
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Feststellbremse für ein Fahrzeug mit den Merkmalen des Patentanspruchs 1 weist demgegenüber den Vorteil auf, dass sie besonders einfach und kompakt hergestellt werden kann. Zur Aktivierung der Feststellbremse sind erfindungsgemäß weiterhin nur relativ geringe Kräfte notwendig. Dies wird erfindungsgemäß dadurch erreicht, dass ein Aktuator eine Hebelvorrichtung betätigt, welche ihrerseits mit einem Seilzug der Feststellbremse verbunden ist. Dadurch kann ein Aktuator signifikant verkleinert werden, da zur Feststellung des Fahrzeugs über die Hebelvorrichtung geringere Kräfte notwendig sind. Die erfindungsgemäße Feststellbremse weist dabei einen einfachen und kompakten Aufbau auf.The Parking brake according to the invention for a Vehicle with the features of claim 1, in contrast, the Advantage on that they are made very simple and compact can be. To activate the parking brake according to the invention continue only relatively small forces necessary. This is inventively characterized achieved that an actuator operates a lever device, which in turn connected to a cable of the parking brake. As a result, an actuator can be significantly reduced because of Detecting the vehicle over the lever device lower forces are necessary. The parking brake according to the invention has a simple and compact design.
Die Unteransprüche zeigen bevorzugte Weiterbildungen der Erfindung.The under claims show preferred developments of the invention.
Die Hebelvorrichtung umfasst vorzugsweise einen ersten und zweiten Schenkel, welche schwenkbar an einer Angriffsvorrichtung für den Aktuator angeordnet sind. Jeder der Schenkel ist mit dem Seilzug verbunden, wobei der Seilzug an jedem Ende jeweils mit einem Bremselement verbunden ist.The Lever device preferably comprises a first and second leg, which are pivotally mounted on an attack device for the actuator. Each of the legs is connected to the cable, with the cable each connected to a brake element at each end.
Um eine Reibung zwischen der Hebelvorrichtung und dem Seilzug während der Betätigung möglichst klein zu halten, ist vorzugsweise zwischen den Schenkeln der Hebelvorrichtung und dem Seilzug jeweils eine Umlenkrolle angeordnet. Die Umlenkrollen sind dabei an den Schenkeln der Hebelvorrichtung gelagert und der Seilzug läuft über die Umlenkrollen.Around a friction between the lever device and the cable during the Actuation as possible is small, is preferably between the legs of the lever device and the cable each arranged a pulley. The pulleys are stored on the legs of the lever device and the Cable runs over the Pulleys.
Besonders bevorzugt ist die Umlenkrolle am Schenkel der Hebelvorrichtung mittels einer Welle gelagert, wobei die Welle gleichzeitig noch als Führungselement ausgebildet ist.Especially Preferably, the deflection roller on the leg of the lever device by means a shaft mounted, the shaft at the same time as a guide element is trained.
Hierzu weist die Welle einen Führungsabschnitt auf, welcher in einer Ausnehmung angeordnet ist. Der Führungsabschnitt ist beispielsweise eine Verlängerung der Welle, welche über die Breite des Schenkels der Hebelvorrichtung und der Umlenkrolle vorsteht. Die Ausnehmung ist vorzugsweise ein Langloch.For this the shaft has a guide section on, which is arranged in a recess. The guide section is for example an extension the wave, which over the width of the leg of the lever device and the guide roller protrudes. The recess is preferably a slot.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist zur Führung der Hebelvorrichtung eine erste Ausnehmung für den ersten Schenkel und eine zweite Ausnehmung für den zweiten Schenkel vorgesehen, welche koaxial zueinander angeordnet sind.According to one preferred embodiment of the invention is for guiding the Lever a first recess for the first leg and a second recess for provided the second leg, which are arranged coaxially with each other.
Der Aktuator umfasst vorzugsweise einen Elektromotor und eine Spindeleinrichtung mit einer Spindel und einer Mutter. Durch Betätigung des Elektromotors kann die Spindel rotieren und eine Relativposition der Mutter relativ zur Spindel geändert werden. Die Hebelvorrichtung ist dabei an der Mutter angeordnet und wird aufgrund der Bewegung der Mutter betätigt.Of the Actuator preferably comprises an electric motor and a spindle device with a spindle and a nut. By pressing the electric motor can the spindle rotate and a relative position of the nut relative changed to spindle become. The lever device is arranged on the mother and is operated due to the movement of the nut.
Gemäß einer anderen bevorzugten Ausgestaltung der Erfindung ist der Aktuator als hydraulischer oder pneumatischer Aktuator ausgebildet. Ein derartiger Aktuator weist einen Kolben auf, welcher mit der Hebelvorrichtung verbunden ist, so dass bei einer Bewegung des Kolbens infolge eines Druckaufbaus die Hebelvorrichtung betätigt wird.According to one Another preferred embodiment of the invention is the actuator designed as a hydraulic or pneumatic actuator. Such a Actuator has a piston, which with the lever device is connected, so that upon movement of the piston due to a Pressure structure, the lever device is actuated.
Um die auf den Seilzug ausgeübte Kraft zu überwachen, ist vorzugsweise eine Sensoreinrichtung vorgesehen. Hierdurch wird sichergestellt, dass über die Hebelvorrichtung die notwendige Verriegelungskraft zur Feststellung des Fahrzeugs bereitgestellt wird. Sollte z.B. aufgrund einer Temperaturänderung die Verriegelungskraft nachlassen, wird dies durch die Sensoreinrichtung erfasst und ein entsprechendes Signal an eine Steuereinheit übermittelt, welche den Aktuator nochmals betätigt, um eine Nachstellung der Feststellbremse durchzuführen.Around the force exerted on the cable Force to monitor, a sensor device is preferably provided. This will ensured that over the lever device the necessary locking force for detection of the vehicle is provided. Should be e.g. due to a temperature change the locking force is released, this is due to the sensor device detected and transmitted a corresponding signal to a control unit, which press the actuator again, to perform a readjustment of the parking brake.
Die erfindungsgemäße Feststellbremse kann in allen Bremsanlagen von Fahrzeugen, wie beispielsweise Trommelbremsen oder Scheibenbremsen mit integrierter Trommelbremse (Drum-in-Head-Bremse) verwendet werden.The parking brake according to the invention can be used in all brake systems of vehicles, such as drum brakes or discs brakes with integrated drum brake (drum-in-head brake) can be used.
