Description

Scheibenbremse eines Nutzfahrzeugs  Disc brake of a commercial vehicle
Die vorliegende Erfindung betrifft eine pneumatisch oder elektromotorisch betätigbare Scheibenbremse eines Nutzfahrzeugs gemäß dem Oberbegriff des Anspruchs 1 . The present invention relates to a pneumatically or electromotively operable disc brake of a commercial vehicle according to the preamble of claim 1.
Gattungsgemäße Scheibenbremsen bestehen im Wesentlichen aus einer Bremsscheibe, mindestens einem, in der Regel zwei Bremsbelägen, einem die Bremsscheibe überspannenden Bremssattel sowie einem ortsfesten Bremsträger mit jeweiligen Belagschächten, in denen die Bremsbeläge beidseits der Bremsscheibe einhegen. Generic disc brakes consist essentially of a brake disc, at least one, usually two brake pads, a brake caliper spanning caliper and a stationary brake carrier with respective lining shafts in which einhegen the brake pads on both sides of the brake disc.
Die Bremsbeläge müssen dabei zur ordnungsgemäßen Funktion der Scheibenbremse im Bremssattel bzw. dem Bremsträger axial zur Drehachse der Scheibenbremse geführt und radial fixiert werden, um sie gegen ein Herausfal- len zu sichern. The brake pads must be guided for proper operation of the disc brake in the caliper or the brake carrier axially to the axis of rotation of the disc brake and fixed radially to secure them against falling out.
Dazu weist der Bremsträger zur Aufnahme der Bremsbeläge jeweils zwei in Umfangsrichtung der Bremsscheibe hintereinander angeordnete Trägerhörner auf, die zusammen mit einer die Trägerhörner miteinander verbindenden Stre- be den Belagschacht zur Aufnahme eines jeweiligen Bremsbelages bilden. For this purpose, the brake carrier for receiving the brake pads in each case two in the circumferential direction of the brake disc successively arranged carrier horns, which together with a carrier horns interconnecting strut form the lining shaft for receiving a respective brake pad.
Zur Montage und Demontage der Bremsbeläge im Servicefall ist es bekannt, die Bremsbeläge und die Trägerhörner des Bremsträgers so auszubilden, dass die Bremsbeläge radial zur Drehachse der Bremsscheibe aus dem Belag- schacht des Bremsträgers entnommen werden können. For assembly and disassembly of the brake pads in case of service, it is known to form the brake pads and the carrier horns of the brake carrier so that the brake pads can be removed radially to the axis of rotation of the brake disc from the lining shaft of the brake carrier.
Bekannt ist auch, beispielsweise aus der DE 22 55 678 C3, die Bremsbeläge und die Trägerhörner derart zu gestalten, dass die Bremsbeläge an einem oder beiden der Trägerhörner radial formschlüssig fixiert sind. Im ersteren Fall kön- nen die Bremsbeläge dabei durch eine Drehbewegung um eine zur Drehachse der Bremsscheibe parallelen Drehachse aus dem Belagschacht entnommen werden; im zweiteren Fall müssen die Bremsbeläge zur Entnahme zunächst aus dem Eingriff mit den Trägerhörnern in Richtung der Drehachse der Bremsscheibe verschoben werden, bevor sie anschließend aus dem Belagschacht durch eine im Bremssattel vorgesehene Belagschachtöffnung entnommen wer- den können. It is also known, for example from DE 22 55 678 C3, to make the brake pads and the carrier horns such that the brake pads are fixed radially positively on one or both of the carrier horns. In the former case, the brake linings can be removed from the lining shaft by a rotational movement about an axis of rotation parallel to the axis of rotation of the brake disc become; In the second case, the brake linings for removal must first be moved out of engagement with the carrier horns in the direction of the axis of rotation of the brake disc, before they can then be removed from the lining shaft through a provided in the caliper lining opening.
Um bei der letztgenannten Anordnung den Ein- und Ausbau der Bremsbeläge zu ermöglichen, ist es erforderlich, die Baulänge der Scheibenbremse in Richtung der Drehachse der Bremsscheibe gegenüber dem Aufbau mit radial ent- nehmbaren Bremsbelägen entsprechend zu verlängern. In order to enable the installation and removal of the brake pads in the latter arrangement, it is necessary to extend the length of the disc brake in the direction of the axis of rotation of the brake disc relative to the structure with radially removable brake pads accordingly.
Aufgabe der vorliegenden Erfindung ist es, eine Scheibenbremse der gattungsgemäßen Art derart weiterzuentwickeln, dass auch bei einlaufseitig und aus- laufseitig radial zur Drehachse der Bremsscheibe formschlüssig an Trägerhör- nern des Bremsträgers gehaltene Bremsbeläge ohne Vergrößerung der Baulänge der Scheibenbremse in einfacher Weise ein- und ausbaubar sind. Object of the present invention is to develop a disc brake of the generic type such that even at the inlet side and auslaufseitig radially to the axis of rotation of the brake disc form fit to Trägerhör- nern of the brake carrier held brake pads without increasing the length of the disc brake in a simple manner and expandable are.
Diese Aufgabe wird durch eine pneumatisch oder elektromotorisch betätigbare Scheibenbremse eines Nutzfahrzeugs mit den Merkmalen des Anspruchs 1 ge- löst. This object is achieved by a pneumatically or electromotively operable disc brake of a commercial vehicle having the features of claim 1.
Bei der erfindungsgemäßen pneumatisch oder elektromotorisch betätigbaren Scheibenbremse mit einem eine Bremsscheibe übergreifenden, verschiebbaren Bremssattel, beidseitig der Bremsscheibe in einem Belagschacht eines Bremsträgers angeordneten Bremsbelägen mit jeweiligen Belagträgerplatten und einem an dieser befestigten Reibbelag, bei der ein zuspannseitiger Bremsbelag mithilfe einer Zuspannrichtung und ein reaktionsseitiger Bremsbelag mit- hilfe eines Bremssattelrückens durch Verschieben des Bremssattels gegen die Bremsscheibe drückbar ist, und bei dem die Bremsbeläge einlaufseitig und auslaufseitig radial zur Drehachse der Bremsscheibe formschlüssig an Trägerhörnern des Bremsträgers gehalten sind, ist zwischen dem reaktionsseitiger Bremsbelag und dem Bremssattelrücken eine Druckplatte angeordnet. In the pneumatically or electromagnetically actuated disc brake according to the invention with a brake disc cross-slidable caliper, both sides of the brake disc in a lining shaft of a brake carrier arranged brake pads with respective lining carrier plates and a friction lining attached thereto, in which a zuspannseitiger brake pad using a Zuspannrichtung and a reaction-side brake lining - Help a caliper backrest can be pressed by moving the caliper against the brake disc, and in which the brake pads on the inlet side and outlet side radially to the axis of rotation of the brake disc are held form-fitting carrier horns of the brake carrier, a pressure plate is disposed between the reaction-side brake pad and the brake caliper.
Mithilfe dieser Druckplatte, die zwischen dem Sattelrücken und dem reaktions- seitigen Bremsbelag entnehmbar angeordnet ist, lassen sich die formschlüssigen Bremsbeläge zum Auswechseln derselben in einfacher Weise dadurch entnehmen und wieder in den jeweiligen Belagschacht einsetzen, dass die Druckplatte vor einem Bremsbelagwechsel aus ihrer Betriebsposition zwischen Sattelrücken und reaktionsseitigem Bremsbelag radial entnommen und nach erfolgtem Bremsbelagwechsel wieder eingesetzt und fixiert wird. By means of this pressure plate, which is arranged removably between the saddle back and the reaction-side brake pad, the positive brake pads for replacing the same can be easily removed and reinserted in the respective lining shaft, that the pressure plate before a brake pad change from its operating position between Saddle back and reaction-side brake pad removed radially and after the brake pad replacement is reinserted and fixed.
Vorteilhafte Ausführungsvarianten sind Gegenstand der Unteransprüche. Advantageous embodiments are the subject of the dependent claims.
Gemäß einer vorteilhaften Ausführungsvariante der Erfindung weist die Druckplatte in Zuspannrichtung eine Dicke auf, die mindestens der halben Dicke der Belagträgerplatte des reaktionsseitigen Bremsbelags entspricht. Dadurch kann im Servicefall bei herausgenommener Druckplatte der reaktionsseitige Brems- belag hinreichend weit aus dem Eingriff im Belagschacht parallel zur Drehachse der Bremsscheibe verschoben werden, um ihn anschließend radial durch die Belagschachtöffnung im Bremssattel herausnehmen zu können. According to an advantageous embodiment of the invention, the pressure plate in the application direction has a thickness which corresponds to at least half the thickness of the lining carrier plate of the reaction-side brake lining. As a result, in the case of service when the pressure plate is removed, the reaction-side brake lining can be displaced sufficiently far out of engagement in the lining shaft parallel to the axis of rotation of the brake disk so that it can then be removed radially through the lining shaft opening in the brake caliper.
Die Druckplatte ist gemäß einer weiteren bevorzugten Ausführungsvariante be- vorzugt am Bremssattelrücken abnehmbar festgelegt. Dazu ist besonders bevorzugt auf einer Seitenfläche der Druckplatte wenigstens ein Befestigungsvorsprung zur Fixierung am Bremssattelrücken angeformt, der im Servicefall leicht zugänglich ist. Gemäß einer weiteren bevorzugten Ausführungsvariante ist der Befestigungsvorsprung als senkrecht zur Seitenfläche der Druckplatte vorstehender Ring ausgebildet, durch dessen Ringöffnung ein am Bremssattelrücken fixierbarer Bolzen durchsteckbar ist. Zur Festlegung der Druckplatte am Bremssattelrücken ist nach einer weiteren vorteilhaften Ausgestaltung der Erfindung am Bremssattelrücken ein Vorsprung vorgesehen. Dieser Vorsprung dient bevorzugt des Weiteren auch der Fixierung eines Belaghaltebügels, der die Belagschachtöffnung des Bremssattels in Richtung der Drehachse der Bremsscheibe überspannt und als Widerlager für ggfs. an den Belagträgerplatten der Bremsbeläge angeordneten Belaghaltefedern dient. The pressure plate is preferably detachably fixed on the brake caliper back in accordance with a further preferred embodiment variant. For this purpose, at least one fastening projection for fixing to the brake caliper back is particularly preferably formed on a side surface of the pressure plate, which is easily accessible in case of service. According to a further preferred embodiment variant of the fastening projection is formed as perpendicular to the side surface of the pressure plate projecting ring through the ring opening a fixable on the brake caliper bolt is pushed through. Laying down the pressure plate on the brake caliper back a projection is provided according to a further advantageous embodiment of the invention on the brake caliper back. This projection is preferably further also the fixation of a Belaghaltebügels which spans the lining shaft opening of the caliper in the direction of the axis of rotation of the brake disc and serves as an abutment for possibly. Located on the lining carrier plates of the brake pads pad retaining springs.

In Figur 1 ist mit dem Bezugszeichen 1 in schematischer Darstellung eine Scheibenbremse für ein Nutzfahrzeug bezeichnet, mit einem eine nicht gezeigte Bremsscheibe überspannenden Bremssattel 2, der axial zu einer Drehachse der Bremsscheibe verschiebbar an einem ortsfesten Bremsträger 6 befestigt ist. In dem Bremsträger 6 sind jeweilige Bremsbeläge 3, 4 angeordnet, die im Fall einer Bremsung gegen die Bremsscheibe gedrückt werden. In Figure 1, reference numeral 1 is a schematic representation of a disc brake for a commercial vehicle, with a not shown brake disc spanning caliper 2, which is axially fixed to a rotational axis of the brake disc slidably mounted on a stationary brake carrier 6. In the brake carrier 6 respective brake pads 3, 4 are arranged, which are pressed in the case of braking against the brake disc.
Die Bremsbeläge 3, 4 und der Bremsträger 6 sind dabei, wie in den Figuren 3 und 4 gezeigt, derart geformt, dass die Bremsbeläge 3, 4, eingesetzt in den jeweiligen Belagschacht 61 des Bremsträgers 6, radial und in Umfangs- oder Drehrichtung der Bremsscheibe formschlüssig im Belagschacht 61 gehalten sind. The brake pads 3, 4 and the brake carrier 6 are, as shown in Figures 3 and 4, shaped such that the brake pads 3, 4, inserted into the respective lining shaft 61 of the brake carrier 6, radially and in the circumferential or rotational direction of the brake disc are positively held in the lining shaft 61.
Dazu weist der Bremsträger 6 jeweilige durch Bremsträgerhörner 62 und einen diese verbindenden Querträger bildenden Belagschacht 61 auf, wobei die Trä- gerhörner 62, 63 sowohl einlaufseitig und auslaufseitig Ausnehmungen 64 aufweisen, in die entsprechend geformte Vorsprünge 33, 43 von Belagträgerplatten 31 , 41 der Bremsbeläge 3, 4 angeformt sind. Die Bremsbeläge 3, 4 sind im Wesentlichen symmetrisch gestaltet, so dass jeder der Bremsbeläge 3, 4 sowohl zuspannseitig als auch reaktionsseitig in den jeweiligen Belagschacht 61 des Bremsträgers 6 einsetzbar ist. For this purpose, the brake carrier 6 has respective lining shaft 61 which forms by means of brake carrier horns 62 and a cross member which connects them. gerhörner 62, 63 both inlet side and outlet side recesses 64 have, in the correspondingly shaped projections 33, 43 of lining carrier plates 31, 41 of the brake pads 3, 4 are formed. The brake linings 3, 4 are designed substantially symmetrically, so that each of the brake linings 3, 4 can be inserted in the respective lining shaft 61 of the brake carrier 6 both on the application side and on the reaction side.
Der Bremssattel 2 weist eine Belagschachtöffnung 21 auf, durch die die Brems- beläge 3, 4 radial zur Drehachse der Bremsscheibe in den jeweiligen Belagschacht 61 des Bremsträgers 6 einsetzbar bzw. herausnehmbar sind. The brake caliper 2 has a covering shaft opening 21, through which the brake linings 3, 4 can be inserted or removed radially into the respective lining shaft 61 of the brake carrier 6 radially to the axis of rotation of the brake disk.
Bedingt durch die Vorsprünge 33 der Belagträgerplatten 31 , 41 müssen die Bremsbeläge 3, 4 zum Einbau in den jeweiligen Belagschacht 61 radial in einen Raum zwischen einem zuspannseitigen bzw. reaktionsseitigen Rand des Bremssattels 2 und den diesen zugewandten Außenseiten der jeweiligen Trägerhörner 62, 63 radial in Richtung der Drehachse der Bremsscheibe eingeschoben und bei Erreichen der Vorsprünge 33, 43 der Belagträgerplatten 31 , 41 axial zur Drehachse der Bremsscheibe zwischen die Trägerhörner 62, 63 verschoben werden. Due to the projections 33 of the lining carrier plates 31, 41, the brake pads 3, 4 for installation in the respective lining shaft 61 radially in a space between a zuspannseitigen or reaction-side edge of the caliper 2 and the outer sides facing the respective carrier horns 62, 63 radially in Direction of the axis of rotation of the brake disc inserted and upon reaching the projections 33, 43 of the lining carrier plates 31, 41 axially to the axis of rotation of the brake disc between the carrier horns 62, 63 are moved.
Im eingebauten Zustand wird der zuspannseitige Bremsbelag 4 mithilfe einer nicht dargestellten Zuspanneinrichtung, üblicherweise bestehend aus einer oder zwei Stellspindeln mit daran angesetztem Druckstück, gegen die Bremsscheibe gedrückt, während ein reaktionsseitiger Bremsbelag 3 durch Verschieben des Bremssattels 2 mithilfe des Bremssattelrückens 24 gegen die Bremsscheibe gedrückt wird. When installed, the application-side brake pad 4 is pressed against the brake disc by means of an application device, not shown, usually consisting of one or two adjusting spindles attached thereto pressure piece, while a reaction-side brake pad 3 is pressed by moving the caliper 2 by means of the brake caliper back 24 against the brake disc ,
Um einen einfach durchführbaren Ein- und Ausbau der Bremsbeläge 3, 4 vornehmen zu können, ist zwischen dem reaktionsseitigen Bremsbelag 3 und dem Bremssattelrücken 24 eine Druckplatte 5 angeordnet. Diese Druckplatte 5 wird zum Austausch der Bremsbeläge 3, 4 zwischen dem reaktionsseitigen Bremsbelag 3 und dem Bremssattel rücken 24 herausgenommen und schafft dadurch den notwendigen Bauraum, um die Belagträgerplatte 31 des reaktionsseitigen Bremsbelags 3 aus dem Eingriff mit den Trägerhörnern 63 des Bremsträgers 6 seitlich, d.h. axial zur Drehachse der Bremsscheibe herausschieben zu können, um dann den reaktionsseitigen Bremsbelag 3 radial nach oben durch die Belagschachtöff- nung 21 im Bremssattel 2 herausnehmen zu können. Um die Baulänge der Scheibenbremse axial zur Drehachse der Bremsscheibe bei gleichbleibender anfänglicher Dicke der Reibbeläge 32, 42 der Bremsbeläge 3, 4 gegenüber solchen Bremssätteln von Scheibenbremsen beibehalten zu können, bei denen die Bremsbeläge ohne axiale Verschiebung radial aus den jeweiligen Belagschächten herausgenommen werden können, ist der Bremssattelrücken 24, der den reaktionsseitigen Rahmen des Bremssattels 2 bildet, um die Dicke der Druckplatte 5 verjüngt ausgebildet. Die Druckplatte 5 ist dabei in Zuspannrichtung bevorzugt zumindest halb so dick wie die Belagträgerplatte 31 . Bei der in Figur 1 gezeigten Ausführungsvariante ist die Dicke dD der Druckplatte 5 etwa gleich der Dicke dB der Belagträgerplatte 31 des reaktionsseitigen Bremsbelags 3. Wichtig ist, für den Ausbau und Einbau der Bremsbeläge 3, 4 hinreichend Bauraum zum Verschieben der Belagträgerplatte 31 des reaktionsseitigen Bremsbelags 3 bereitzustellen, damit diese aus dem formschlüssigen Eingriff mit den Trägerhörnern 63 herausgenommen bzw. in diesen eingesetzt werden kann. In order to make a simple feasible installation and removal of the brake pads 3, 4, a pressure plate 5 is disposed between the reaction-side brake pad 3 and the brake caliper back 24. This pressure plate 5 is to replace the brake pads 3, 4 back between the reaction-side brake pad 3 and the caliper 24 removed and thereby creates the necessary space to the pad carrier plate 31 of the reaction-side brake pad 3 from engagement with the carrier horns 63 of the brake carrier 6 side, ie be able to push out axially to the axis of rotation of the brake disc, in order then to be able to remove the reaction-side brake pad 3 radially upward through the lining shaft opening 21 in the brake caliper 2. In order to maintain the overall length of the disc brake axially to the axis of rotation of the brake disc with a constant initial thickness of the friction linings 32, 42 of the brake pads 3, 4 against such brake calipers of disc brakes, where the brake pads can be removed without axial displacement radially from the respective lining shafts, is the brake caliper back 24, which forms the reaction-side frame of the caliper 2, formed to the thickness of the pressure plate 5 tapers. The pressure plate 5 is preferably at least half as thick as the lining carrier plate 31 in the application direction. In the embodiment shown in Figure 1, the thickness d D of the pressure plate 5 is approximately equal to the thickness d B of the lining carrier plate 31 of the reaction-side brake pad 3. It is important for the removal and installation of the brake pads 3, 4 sufficient space for moving the lining carrier plate 31 of provide reaction-side brake pads 3, so that they can be removed from the positive engagement with the carrier horns 63 and inserted into this.
Die Breite der Trägerhörner 62, 63 des Bremsträgers 6 in Zuspannrichtung kann dabei unverändert beibehalten werden. The width of the carrier horns 62, 63 of the brake carrier 6 in the application direction can be maintained unchanged.
Wie aus einer Zusammenschau der Figuren 1 und 2 ersichtlich, ist die Druckplatte 5 bevorzugt am Bremssattelrücken 24 abnehmbar festgelegt. Dazu ist bevorzugt an einer Seitenfläche 51 der Druckplatte 5 wenigstens ein Befestigungsvorsprung 52 zur Fixierung am Bremssattelrücken 24 angeformt. In der in Figur 2 gezeigten bevorzugten Ausführungsvariante sind zwei Befestigungsvorsprünge 52 an der Druckplatte 5 angeformt. Denkbar ist auch, die Befestigungsvorsprünge 52 als separate Bauteile an der Druckplatte 5 durch Verkleben, Verschweißen oder dergleichen zu befestigen. As can be seen from a comparison of Figures 1 and 2, the pressure plate 5 is preferably removably fixed to the brake caliper back 24. For this purpose, at least one fastening projection 52 is preferably integrally formed on a side surface 51 of the pressure plate 5 for fixing to the brake caliper back 24. In the preferred embodiment variant shown in FIG. 2, two fastening projections 52 are integrally formed on the pressure plate 5. It is also conceivable to attach the fastening projections 52 as separate components to the pressure plate 5 by gluing, welding or the like.
Die Befestigungsvorsprünge 52 sind dabei bevorzugt als senkrecht zur Seitenfläche 51 der Druckplatte 5 vorstehende Ringe ausgebildet, durch deren jeweiliger Ringöffnung 53 ein am Bremssattel rücken 24 fixierbarer (nicht gezeigter) Bolzen durchsteckbar ist. Am Bremssattelrücken 24 ist entsprechend bevorzugt ein Vorsprung 22 mit einer Bohrung 23 vorgesehen, an dem die Druckplatte 5 abnehmbar festgelegt ist. Dieser Vorsprung 22 dient vorzugsweise zusätzlich zur Festlegung eines Endes eines (nicht dargestellten) Belaghaltebügels, der die Belagschachtöffnung 21 des Bremssattels 2 axial zur Drehachse der Bremsscheibe überspannt. The fastening projections 52 are preferably formed as perpendicular to the side surface 51 of the pressure plate 5 projecting rings through the respective annular opening 53 a back on the caliper 24 fixable (not shown) bolt is pushed through. On the brake caliper back 24, a projection 22 is preferably provided with a bore 23 to which the pressure plate 5 is detachably fixed. This projection 22 is preferably used in addition to defining one end of a (not shown) pad retaining strap, which spans the lining shaft opening 21 of the caliper 2 axially to the axis of rotation of the brake disc.
Die Druckplatte 5 ist ebenso wie die Bremsbeläge 3, 4 durch die Belagschachtöffnung 21 des Bremssattels 2 radial zur Drehachse der Bremsscheibe einsetzbar und herausnehmbar. The pressure plate 5 is as well as the brake pads 3, 4 can be inserted and removed through the lining shaft opening 21 of the brake caliper 2 radially to the axis of rotation of the brake disc.
Die Seitenränder der Druckplatte 5 sind dabei bevorzugt parallel zueinander ausgerichtet, so dass die Druckplatte 5 in einfacher Weise radial zur Drehachse der Bremsscheibe in die Belagschachtöffnung 21 zwischen einem Rand des Bremssattels 2 und den jeweiligen Trägerhörnern 63 des Bremsträgers 6 einführbar und herausnehmbar ist. The side edges of the pressure plate 5 are preferably aligned parallel to each other, so that the pressure plate 5 in a simple manner radially to the axis of rotation of the brake disc in the lining shaft opening 21 between an edge of the caliper 2 and the respective carrier horns 63 of the brake carrier 6 can be inserted and removed.
