Abstract

A radial web (4) of the brake housing (2) has a. U-shaped opening (6). This opening has. U-shaped cut-outs (12,14) in its side walls. These cut-outs are open at the side of the disc brake and at the side of the opening. The webs (16,18) of the "U", formed by the opening, has further cut-outs (20,22) at the bottom ends which are open at the side facing the brake disc. A spring clip (30) fits with its two ends (36,38) in the cut-outs in the webs. The main part (50), of the spring clip, lies in the cut-outs at the bottom ends of the web so that the spring is locked radially with reference to the brake disc axis.

Description

Die Erfindung betrifft eine Teilbelag-Scheibenbremse mit einem Bremsträger und einem am Bremsträger axial verschiebbar befestigten, zwei zu beiden Seiten einer Bremsscheibe angeordnete Bremsbeläge umfassenden Bremsgehäuse und einer den Bremsträger und das Bremsgehäuse gegeneinander verspannenden Feder, die am Bremsgehäuse lösbar befestigt ist und die zumindest einen Arm aufweist, der am Bremsträger anliegt.The invention relates to a partial-pad disc brake one brake carrier and one on the brake carrier axially slidably attached, two on either side of one Comprising brake discs arranged brake pads Brake housing and one of the brake carrier and the brake housing spring tensioning against each other on the brake housing is releasably attached and has at least one arm, which rests on the brake carrier.

Eine derartige Teilbelag-Scheibenbremse ist aus der DE 39 29 748 bekannt. Bei dieser Scheibenbremse ist am Bremsgehäuse am außenliegenden Schenkel eine sich in radialer Richtung erstreckende Ausnehmung vorgesehen, in die das Mittelteil der Feder rastend eingreift und durch einen Hakenansatz verriegelt wird.Such a partial lining disc brake is from the DE 39 29 748 known. With this disc brake is on Brake housing on the outer leg one in radially extending recess provided in the the middle part of the spring engages and engages by one Hook attachment is locked.

Der Erfindung liegt die Aufgabe zugrunde, eine Teilbelag- Scheibenbremse der eingangs genannten Art bezüglich ihrer Verriegelung zu verbessern.The invention has for its object a partial covering Disc brake of the type mentioned with regard to their To improve locking.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Bremsgehäuse eine Ausnehmung aufweist, die einen Abschnitt der Feder derart umgreift, daß die Feder in bezüglich der Bremsscheibenachse radialer Richtung verriegelt ist.This object is achieved in that the Brake housing has a recess that has a section the spring engages such that the spring in relation to the Brake disc axis is locked in the radial direction.

Mit der Erfindung wird ein Herausspringen der Feder aus der Verriegelung auch bei großen Federspannungen vermieden, bzw. bei gleicher Federstärke können größere Verspannungen erzeugt werden.With the invention a spring jumping out of the Locking avoided even with large spring tensions, or With the same spring strength, larger tensions can occur  be generated.

Weitere Merkmale sowie Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispieles anhand der Zeichnung.Further features and advantages of the invention result from the following description of an embodiment based on the drawing.

Es zeigen:Show it:

Fig. 1 den äußeren Schenkel einer Teilbelag-Scheibenbremse mit einer Feder in Vorderansicht und Fig. 1 shows the outer leg of a partial pad disc brake with a spring in front view

Fig. 2 den äußeren Schenkel der Teilbelag-Scheibenbremse mit Feder gemäß Fig. 1 in Rückansicht. Fig. 2 shows the outer leg of the partial lining disc brake with spring according to FIG. 1 in rear view.

In der Zeichnung ist ein Gehäuse 2 einer Teilbelag- Scheibenbremse dargestellt, wobei der innere, eine Betätigungseinheit aufweisende Schenkel und der Brückenabschnitt der des Gehäuses weggebrochen sind. Der Aufbau der Bremse entspricht weitgehend der in der DE 39 29 748 beschriebenen Bremse.In the drawing, a housing 2 of a partial lining disc brake is shown, the inner leg having an actuation unit and the bridge section of the housing having broken away. The structure of the brake largely corresponds to the brake described in DE 39 29 748.

In dem sich radial erstreckenden Schenkel 4 des Gehäuses ist mittig eine U-förmige Öffnung 6 vorgesehen. In den Seitenwänden 8, 10 dieser Öffnung 6 sind U-förmige Ausnehmungen 12, 14 angeordnet, die zur Bremsscheibe hin und zur Mitte der Ausnehmung 6 hin offen sind und die beim Gießvorgang gebildet werden können.A U-shaped opening 6 is provided in the center of the radially extending leg 4 of the housing. In the side walls 8 , 10 of this opening 6 , U-shaped recesses 12 , 14 are arranged which are open towards the brake disc and towards the center of the recess 6 and which can be formed during the casting process.

Am unteren Ende der beiden fingerartigen Abschnitte 16, 18 des Schenkels 4 sind U-förmige Ausnehmungen 20, 22 ausgebildet, die zur Bremsscheibe hin offen sind und die beim Gießvorgang gebildet werden können. Die Ausnehmungen 20, 22 werden durch hakenförmige Erstreckungen gebildet, deren Enden 24, 26 zur Bremsscheibe hin weisen. Um eine weitere Sicherung zu bilden, können diese Enden auch nochmals in radialer Richtung (zur Brückenabschnitt hin weisen (nicht dargestellt).At the lower end of the two finger-like sections 16 , 18 of the leg 4 , U-shaped recesses 20 , 22 are formed which are open towards the brake disc and which can be formed during the casting process. The recesses 20 , 22 are formed by hook-shaped extensions, the ends 24 , 26 of which point towards the brake disc. In order to form a further fuse, these ends can also point again in the radial direction (towards the bridge section (not shown).

Eine Feder 30 weist zwei Endabschnitte 32, 34 auf, die zunächst im wesentlichen radial etwa parallel zu den Seitenwänden der Öffnung 6 verlaufen und dann in axialer Richtung umgebogen sind.A spring 30 has two end sections 32 , 34 which initially run essentially radially approximately parallel to the side walls of the opening 6 and are then bent in the axial direction.

Die in tangentialer Richtung umgebogenen Enden 36, 38 greifen in die Ausnehmungen 12, 14 ein. An die Abschnitte 32, 34 schließen sich tangential verlaufende Abschnitte 40, 42 an die etwa U-Form aufweisen und mit deren äußeren Enden 44, 46 sich die Feder an Armen des Bremsträgers abstützt. Ein Mittelabschnitt 50 der Feder verbindet die Abschnitte 40, 42 und greift in die U-förmigen Ausnehmungen 20, 22 ein. Durch die Form der Ausnehmungen ist sichergestellt, daß auch bei sehr starken Federspannungen der Mittelabschnitt der Feder nicht aus den eine Verriegelung bildenden Ausnehmungen herausspringen kann. Die Auflagefläche 51, 52 der Endabschnitte 24, 26 bilden Unterstützungspunkte zur Erhöhung der Federvorspannung.The ends 36 , 38 bent over in the tangential direction engage in the recesses 12 , 14 . The sections 32 , 34 are adjoined by tangentially extending sections 40 , 42 which have an approximately U-shape and with the outer ends 44 , 46 of which the spring is supported on the arms of the brake carrier. A central section 50 of the spring connects the sections 40 , 42 and engages in the U-shaped recesses 20 , 22 . The shape of the recesses ensures that, even with very strong spring tensions, the central section of the spring cannot jump out of the recesses forming a lock. The bearing surface 51 , 52 of the end sections 24 , 26 form support points for increasing the spring preload.
