Abstract
Description
Die Erfindung betrifft eine Bremsvorrichtung, insbesondere für Kraftfahrzeuge, gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a braking device, in particular for motor vehicles, according to the generic term of claim 1
Herkömmliche Fahrzeugbremsen umfassen ein Reibglied (Bremsbelag), das mittels eines Aktuators gegen die Reibfläche eines abzubremsenden Elements (z. B. eine Bremsscheibe) gedrückt wird. Beim Bremsen kommt es zu einem Verschleiß des Bremsbelags, durch den sich das Lüftspiel zwischen Bremsbelag und gebremstem Element vergrößert. Der von der Bremse zurückzulegende Weg vergrößert sich daher mit zunehmender Lebensdauer und kann im Extremfall so groß werden, dass die Bremswirkung zu spät eintritt oder nur noch sehr gering ist. Um dies zu vermeiden, umfassen bekannte Radbremsen eine Belagverschleiß-Nachstelleinrichtung, die das Lüftspiel zwischen Bremsbelag und Bremsscheibe auf einen vorgegebenen Wert nachstellt. Aus dem Stand der Technik bekannte Nachstelleinrichtungen für elektromechanische Bremsen sind jedoch relativ kompliziert aufgebaut und benötigen relativ viel Bauraum.conventional Vehicle brakes include a friction member (brake pad), which means an actuator against the friction surface an element to be braked (eg a brake disc) is pressed. At the Braking causes wear of the brake pad, through which the air play enlarged between the brake pad and the braked element. The brake to be backed by Path is increasing therefore with increasing life and can be so big in extreme cases, that the braking effect is too late occurs or is only very small. To avoid this, include known wheel brakes a lining wear adjusting device, the clearance between brake pad and brake disc to a predetermined value stalking. Adjustment devices known from the prior art for electromechanical However, brakes are relatively complicated and require relatively much Space.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Bremse, insbesondere eine Scheibenbremse, zu schaffen, die eine sehr einfach aufgebaute Nachstelleinrichtung umfasst, die wenig Bauraum benötigt.It Therefore, the object of the present invention, a brake, in particular a disc brake, to create a very simple structure Adjustment includes, which requires little space.
Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Patentanspruch 1 angegebenen Merkmale. Weitere Ausgestaltungen der Erfindung sind Gegenstand von Unteransprüchen.Is solved this task according to the invention by the features specified in claim 1. Further embodiments The invention are the subject of subclaims.
Ein wesentlicher Aspekt der Erfindung besteht darin, die Bremse mit einem mehrteiligen Bremssattel auszustatten, der wenigstens zwei Schenkel aufweist, die in einer senkrecht zur Reibfläche verlaufenden Richtung (Normalrichtung) gegeneinan der verstellt werden können. Auf diese Weise kann der Belagverschleiß durch einfache Reduzierung des Abstands zwischen den beiden Schenkeln ausgeglichen werden. Die vorgeschlagene Nachstelleinrichtung ist sehr einfach realisierbar und benötigt wenig Bauraum.One essential aspect of the invention is to use the brake to equip a multi-part caliper, the at least two legs having in a direction perpendicular to the friction surface (normal direction) against each other can be adjusted. In this way the lining wear can be reduced by simple reduction be compensated for the distance between the two legs. The proposed adjusting device is very easy to implement and needs little Space.
Gemäß einer bevorzugten Ausführungsform der Erfindung umfasst die Nachstelleinrichtung ein Element, das die beiden Schenkel des geteilten Bremssattels miteinander verbindet. Das Element ist vorzugsweise derart gestaltet, dass es wenigstens einen Teil der Bremskräfte aufnimmt.According to one preferred embodiment of Invention, the adjusting device comprises an element that the connects both legs of the split caliper together. The element is preferably designed such that it has at least one Part of the braking forces receives.
Der geteilte Bremssattel umfasst vorzugsweise einen ersten Schenkel, der auf einer Seite des abzubremsenden Elements angeordnet ist, und einen zweiten Schenkel, der auf der anderen Seite des abzubremsenden Elements angeordnet ist. Die beiden Schenkel verlaufen vorzugsweise etwa parallel zueinander und sind relativ zueinander beweglich.Of the divided caliper preferably comprises a first leg, which is arranged on one side of the element to be braked, and a second leg, on the other side of the braked Elements is arranged. The two legs preferably run approximately parallel to each other and are movable relative to each other.
Die erfindungsgemäße Nachstelleinrichtung kann beispielsweise eine elektromotorisch betätigte Spindel umfassen, die die beiden Schenkel des Bremssattels miteinander verbindet. Alternativ könnte auch eine Zahnstange oder eine andere bekannte Stellvorrichtung verwendet werden.The Adjustment device according to the invention can For example, comprise an electric motor-operated spindle, the connects the two legs of the caliper together. alternative could also a rack or other known actuator be used.
Gemäß einer speziellen Ausführungsform der Erfindung sind die Schenkel des geteilten Bremssattels etwa L-förmig gebildet und umfassen jeweils einen parallel zur Reibfläche verlaufenden Abschnitt und einen in Normalrichtung verlaufenden Abschnitt, an dem sie eine Führung aufweisen.According to one special embodiment of the Invention, the legs of the split caliper are formed approximately L-shaped and each comprise a parallel to the friction surface extending portion and a normal running section where she a guide exhibit.
An der Führung sind vorzugsweise Rastmittel vorgesehen, die eine Bewegung aufeinander zu, aber nicht voneinander weg, ermöglicht. Der Bremssattel kann an dieser Verbindung somit Bremskräfte aufnehmen.At the leadership Locking means are preferably provided which move towards each other to, but not away from each other, allows. The caliper can thus absorb braking forces at this connection.
Der vorgeschlagene geteilte Bremssattel kann beispielsweise in einer Keilbremse oder einer anderen, elektromechanisch be tätigten Bremse eingesetzt werden. Im Falle einer Keilbremse umfasst die Bremsvorrichtung vorzugsweise ein bewegliches Keilelement mit einer Keilfläche, das sich an einem korrespondierenden Widerlager abstützt, welches mit einem der Schenkel fest verbunden ist.Of the proposed split caliper can, for example, in a Wedge brake or other, electromechanically actuated brake be used. In the case of a wedge brake includes the braking device Preferably, a movable wedge element with a wedge surface, the is supported on a corresponding abutment, which with one of Leg is firmly connected.
Der Bremssattel ist vorzugsweise nach dem Prinzip eines Schwimmsattels konstruiert.Of the Brake caliper is preferably according to the principle of a floating caliper constructed.
