Description
Scheibenbremse Die Erfindung bezieht sich auf eine druckmittelbetätigte Teilbelagscheibenbremse, insbesondere für Kraftfahrzeuge, mit zwei voneinander unabhängigen Druckmittelkreisen und einem beweglich am Fahrzeugrahmen angeordneten Zuspannelement, das die Bremascheibe umgreift und nur auf einer Seite der Bremascheibe Betätigungeorgane aufweist. Druckmittelbetätigte Bremaanlagen mit zwei voneinander unabhängigen Bremskreisen werden überall da verwandt, wo es darauf ankommt, daß bei Auftreten von Störungen, beispielsweise durch Leakagen, ein möglichst großer Anteil der ursprünglich vorhandenen Bremskraft vorhanden bleibt. Es ist dabei ohne weiteres möglich, jedes Fahrzeugrad mit einer doppelten Bremaanlage auszurüsten, was jedoch den Nachteil hat, daß der Bauaufwand unverhältnismäßig groß wird gegenüber der Einkreisanlage, während das Bestreben jedoch dahin geht, die der Zweikreiobremsanlage innewohnende größere Betriebssicherheit auch ohne großen Aufwand zu erreichen.Disc brake The invention relates to a pressure medium operated Partly lined disc brake, in particular for motor vehicles, with two independent ones Pressure medium circuits and a clamping element movably arranged on the vehicle frame, which engages around the brake disk and actuating members only on one side of the brake disk having. Pressure medium operated Brema systems with two independent brake circuits are used wherever it is important that in the event of malfunctions, for example through leakage, as large a proportion as possible of the originally present Braking force remains. It is easily possible to use any vehicle wheel to equip with a double Bremaanlage, but this has the disadvantage that the Construction costs are disproportionately large compared to the single-circuit system, while the However, the aim is to achieve greater operational safety inherent in the dual-circuit brake system can also be reached without great effort.
Es ist bekannt, die Vorder- und Hinterachse jeweils mit einem Bremokreie zu waehen. Hierfür ist lediglich ein Tandem- oder Zwillingszylinder erforderlich. Der Nachteil besteht darin, daß bei Ausfall einen Bremokreiaes jewELs nur eine Fahrzeugachee abgebremst wird, wodurch nur ein Anteil von etwa der Hälfte den Fahrzeuggewiehtes als Reibungsgewicht zur BremBung herangezogen werden kann. In einer anderen bekannten Ausführung ist die Vorderachse mit einer Zweikreiebremaanlage ausgerüstet, wobei an jedem Vorderrad ein Vierzylinderaattel angeordnet ist und jedem Vorderachabremskreie die Bremse einen Hinterrades zugeschaltet ist* Hierfür sind lediglich voineln Vierzylindersattel oder zwei Zweizylindersättel je Rad und insgesamt ein Tandemzylinder erforderlich* Diese Anlage hat jedoch den Nachteil, daß bei Ausfall eines Bremokreiaes eine ungleichmäßige Bremaung des gesamten Fahrzeuges eintritt. Gemäß dem aufgezeigten Stand der Technik wird die Lösung des Problems darin gesehen, daß in jeden Bremsträger beide Bremskreise vorhanden sind* Hierzu tritt die Forderung, daß die bauliche Ausdehnung der Betätigungsorgane am Pahrzeugrad klein bleibt und daß bei Ausfall-eines Bremokreiaes die Betätigungscharakteristik der Bremsanlage möglichst unverändert bleibt* Ebenfalls sollten der Kraftaufwand zur Erzielung der vollen Bremokraft sowie der Pedalweg nicht allzusehr schwanken.It is known to blow the front and rear axles with a brake circle. All that is required for this is a tandem or twin cylinder. The disadvantage is that in the event of failure of a brake circuit, only one vehicle axle is braked, so that only about half of the weight of the vehicle can be used as a friction weight for braking. In another known design, the front axle is equipped with a two-circuit brake system, with a four-cylinder caliper being arranged on each front wheel and the brake of a rear wheel being connected to each front-axle braking circuit however, the disadvantage is that if one brake circuit fails, the entire vehicle will be unevenly braked. According to the prior art shown, the solution to the problem is seen in the fact that both brake circuits are present in each brake carrier remains unchanged * The effort required to achieve full brake force and the pedal travel should also not fluctuate too much.
Der Erfindung liegt die Aufgabe zugrundeg eine äruckmittelbetätigte Teilbelagscheibenbremee der eingangs genannten Gattung zu schaffeng die einen möglichst geringen Raumbedarf aufweist, leicht ein- und auszubauen ist und einen weitreichenden Spielraum in der Auslegung der Volumen-und Druckeharakteristik in der Aufteilung auf beide Bremskreise ermöglicht, ohne daß bei Ausfall eines Bremokreiaes eine sichere Bremsung erschwert ist* Gemäß der Erfindung wird diese Aufgabe dadurch geLöstg daß die beiden Betätigungskolben koaxial hintereinander im Bremazylindergehäuse geführt eindg derart» daß der eine Betätigungekdben direkt auf einen Reibbelag und der andere Betätigungekolben In entgegengesetzter Richtung auf das die Bremaacheibe umgreifende Zuspannelement wirken. Hierbei ist das Bremszylindergehäuse relativ zur Bremascheibe feststehend angeordnet* Innerhalb der beiden als Hohlkolben ausgebildeten Betätigungskolben befindet sich ein konzentrisch angeordneter Kolbenkerng der mit dem Bremazylindergehäuse eine bauliche Einheit bildet.The invention is based on the object of creating a hydraulic fluid-actuated partial-lined disc brake of the type mentioned at the outset, which requires as little space as possible, is easy to assemble and dismantle, and allows extensive leeway in the design of the volume and pressure characteristics in the distribution between the two brake circuits, without is it difficult to secure event of failure of a Bremokreiaes * According to the invention, this object is characterized geLöstg that the two actuating pistons coaxially one behind the other out in Bremazylindergehäuse eindg such 'that the a Betätigungekdben directly on a friction lining and the other Betätigungekolben in the opposite direction to which the Bremaacheibe encompassing Acting clamping element. The brake cylinder housing is fixed relative to the brake disc * Inside the two actuating pistons, which are designed as hollow pistons, there is a concentrically arranged piston core which forms a structural unit with the brake cylinder housing.
In einer Ausführungsform, der Erfindung ist das die Bremsschpite umgreifende Zuspannelement ein Rahmen, der die Bremascheibe längs einer Sekante umgreifte Hierbei ist die Bremascheibe zusätzlich von einer Abstützung TJ-förmig umgriffen, an die sich die Reibglieder in Umfangsrichtung abstützen und die mit dem Zylindergehäuse eine bauliche Einheit bildet. Der Rahmen kann als Schwimmrahmen oder Schwenkrahmen ausgebildet sein.In one embodiment of the invention, it encompasses the brake boom Clamping element is a frame that encompasses the brake disk along a secant the brake disc is additionally encompassed by a support TJ-shaped to which the friction members are supported in the circumferential direction and those with the cylinder housing forms a structural unit. The frame can be used as a floating frame or a swivel frame be trained.
In einer anderen Ausführungsform der Erfindung ist das die Bremsseheibe umgreifende Zuspannelement ein Bremssattel, der die Brensecheibe U-förmig umgreifte Die Druckräume den einen Bremskreiaes liegen am inneren Boden den jeweiligen Betätigungekolbens und die Druckräume des anderen Bremokreiaes liegen an der Stirnringfläche des jeweiligen Betätigungekolbens. Der Kolbenkern weist eine Längsbohrung auf, die die Druckräume des auf den Kolbenboden wirkenden Bremokreiaes miteinander verbindet. Zur Schmierung weist jede Gleitfläche eines jeden Kolbens nur eine Dichtung auf, die an demjenigen Ende der Gleitfläche angeordnet ist, das von einem Druckmittelraum am weitesten entfernt Ist.In another embodiment of the invention, this is the brake disk encompassing application element a brake caliper that encompassed the brake disc in a U-shape The pressure chambers of one of the brake circuits are located on the inner bottom of the respective actuating piston and the pressure chambers of the other Bremokreiaes are on the end ring surface of the respective Actuating piston. The piston core has a longitudinal bore that forms the pressure chambers of the Bremokreiaes acting on the piston crown. For lubrication each sliding surface of each piston has only one seal on that one The end of the sliding surface is arranged which is furthest from a pressure medium space is removed.
In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel näher erläutert.The invention is shown in more detail in an exemplary embodiment in the drawing explained.
Auf die Bremoscheibe 1 wirken die Reibbeläge 2 und 3, Die Reibbeläge 2 und 3 sind von den Belagträgern 4 und 5 gehalten. Der Rahmen 10 umgreift die Bremascheibe 1 in Form einer Sekante und ist in axialer Richtung beweglich. Die Bremoscheibe 1 ist außerdem von einer Abstützung 6 U-förmig umgriffen, an die sich die Reibbeläge 2 und 3 bzw. die Belagträger 4 und 5 in Umfangsrichtung abstützen, Die Abstützung 6 ist ebenso wie das Bremszylindergehäuse 11 fest am Fahrzeugrahmen angeordnet* In dem Bremazylindergehäuse 11 befinden sich die beiden Betätigungekolben 7 und 8, die als Hohlkolben ausgebildet sind und gegeneinander wirken. Hierbei wirkt der Betätigungekolben 7 in der gezeichneten Anordnung nach links über-den Belagträger 5 auf den Reibbelag 3, während der entgegengesetzt wirkende Betätigungskolben 8 seine Kraft auf den rechten Schakel des Rahmens 10 ausübt, der über seinen Umfang auf den anderen Schenkel die Betätigungskraft überträgt, wodurch diese Kraft auf den Belagträger 4 und den Reibbelag 2 einwirkt. Innerhalb des Zylindergehäuses 11 befindet-sich der Kolbenkern 12, auf dem die beiden Betätigungskolben 7 und 8 gleiten. Dieser Kolbenkern 12 bildet zusammen mit dem Zylindergehäuse 11 und der Abstützung 6 eine bauliche Einheit, die insgesamt am Fahrzeugrahmen fest angeordnet ist. Gegen das Eindringen von Schmutz, Staub oder Feuchtigkeit ist der Zylinder mit den Schutzkappen 9 versehen. The friction linings 2 and 3 act on the brake disk 1. The friction linings 2 and 3 are held by the lining carriers 4 and 5 . The frame 10 engages around the brake disk 1 in the form of a secant and is movable in the axial direction. The Bremoscheibe 1 is also 6 U-shape encompassed by a support, the friction pads 2 and 3 and the lining support supported on the 4 and 5 in the circumferential direction, the support 6, like the brake cylinder housing 11 is fixedly arranged on the vehicle frame * In the Bremazylindergehäuse 11 are the two actuating pistons 7 and 8, which are designed as hollow pistons and act against each other. In the arrangement shown, the actuating piston 7 acts to the left via the lining carrier 5 on the friction lining 3, while the actuating piston 8, which acts in the opposite direction, exerts its force on the right bracket of the frame 10 , which transmits the actuating force over its circumference to the other leg, whereby this force acts on the lining carrier 4 and the friction lining 2. Inside the cylinder housing 11 is the piston core 12 on which the two actuating pistons 7 and 8 slide. This piston core 12 forms, together with the cylinder housing 11 and the support 6, a structural unit which is arranged as a whole in a fixed manner on the vehicle frame. The cylinder is provided with protective caps 9 to prevent the ingress of dirt, dust or moisture.
Die Druckräume 13 des Bremokreises II befinden sich an den Stirnringflächen der beiden Hohlkolben 7 und 8, während sich-die Druckräume 14 des Bremokreiaes I an den Kolbenböden befinden. Die Verbindung der Druckräume jeweils eines Bremskreiaes untereinander erfolgt im Bremskreis II durch die Zuführungeleitung, die sich kurz hinter dem Eintritt gabelt, während die Verbindung der Druckräume der beiden Kolben für den Bremskreis I durch eine konzentrische Längebohrung 15 im Kolbenkern 12 erfolgt. Sind beide Bremskreise intakt, so werden die beiden Betätigungskolben 7 und 8 sowohl durch das Druckmittel am Boden als auch an ihrer Stirnringfläche gegeneinander gespreizt und kommen entweder direkt über den Reibbelagträger 5 bzw. über den Bremerahmen'10 zur Anlage. Fällt ein Bremokreie aus, so ist eine vollständige Bremsung ohne Volumen- d,h, Hubwegvergrößerung möglich; lediglich der Bremsdruck ist höher.The pressure chambers 13 of the brake circuit II are located on the end ring surfaces of the two hollow pistons 7 and 8, while the pressure chambers 14 of the brake circuit I are located on the piston crowns. The pressure chambers of each brake circuit are connected to one another in brake circuit II by the feed line that forks just behind the inlet, while the pressure chambers of the two pistons for brake circuit I are connected by a concentric longitudinal bore 15 in piston core 12. If both brake circuits are intact, the two actuating pistons 7 and 8 are spread apart from one another by the pressure medium on the floor as well as on their end ring surface and come into contact either directly via the friction lining carrier 5 or via the brake frame 10. If a brake circuit fails, complete braking without increasing the volume d, h, stroke path is possible; only the brake pressure is higher.
Ein besonderer Vorteil der Erfindung gemäß-dem Ausführungebeispiel besteht darin, daßviele Teile fest mit dem Fahrzeugrahmen verbunden sind. Hierdurch wird der Bauaufwand gering und der Verschleiß in Grenzen gehalten. Lediglich der Rahmen mit den beiden Betätigungskolben ist axial beweglich. In der Ausführung mit einem Rahmen bietet die Erfindung weiterhin die Möglichkeit, die Bremse am Rad mit geringer radialer Erstreckung zu bauen* Die einzelnen druckbeaufschlagten Kolbenflächen der beiden Bremokreise können je nach Erfordernis beliebig ausgelegt werden.A particular advantage of the invention according to the exemplary embodiment consists in that many parts are firmly connected to the vehicle frame. Through this construction costs are low and wear and tear is kept within limits. Only the The frame with the two actuating pistons can move axially. In the version with The invention also offers a frame the possibility of using the brake on the wheel to build small radial extension * The individual pressurized piston surfaces the two brake circuits can be designed as required.
Die vorstehend beaehriebeneng auf eine Scheibenbremse mit einem beweglich am Fahrzeugrahmen angeordneten Zuspannelement gerichteten Merkmale sind sinngemäß in gleich vorteilhafter Weise auch auf fest am Fahrzeugrahmen angeordnete Zuspannelemente - wie Festsättel bzw. Festrahmen - anwendbar*The above-beaehriebeneng directed to a disc brake having a movably arranged on the vehicle frame tightening member features are, mutatis mutandis, in the same advantageous manner also fixedly arranged on the vehicle frame Zuspannelemente - such as calipers or fixed frame - applicable *
