Gleiche Bezugszeichen in den Zeichnungen bezeichnen jeweils gleiche Teile.The same reference numerals in the drawings denote in each case same parts.

Die in Fig. 1 dargestellte Teilbelag-Scheibenbremse besteht aus einem gegossenen Schwimmsattel 1, der in axialer Richtung gleitend über Bolzenführungen mit einem nicht gezeigten, star­ ren Bremsträger verbunden ist. Der Schwimmsattel 1 ist gegen­ über dem Bremsträger mit einer einteiligen Feder 2 verspannt. Die Feder 2, die mit ihren nicht gezeigten Federarmen in be­ kannter Weise gegenüber dem Bremsträger axial verschiebbar ist, ist mit ihren Federenden in U-förmigen unbearbeiteten Ausnehmungen 3 der Schwimmsattelschenkel 4 eingehakt und axial gesichert. Dabei besitzen die Ausnehmungen 3 innenliegend je­ weils einen Absatz 5, der dem eingepreßten, blechartigen Hal­ teelement 6 als Anschlag dient. Die Halteelemente 6 verriegeln die Enden der Feder 2 in radialer Richtung und ermöglichen das Aufbringen der üblichen Federvorspannkraft. Damit ist die Fe­ der 2 ohne weiteren Bearbeitungsaufwand am Schwimmsattel 1 selbst an diesem zu befestigen.The partial lining disc brake shown in Fig. 1 consists of a cast floating caliper 1 which is slidably connected in the axial direction via bolt guides with a not shown, star ren brake carrier. The floating caliper 1 is braced against the brake carrier with a one-piece spring 2 . The spring 2 , which is axially displaceable in known manner with respect to the brake carrier with its spring arms, is hooked with its spring ends in U-shaped unprocessed recesses 3 of the floating caliper legs 4 and axially secured. The recesses 3 have an interior because each has a paragraph 5 which serves as a stop for the pressed-in, sheet-like Hal teelement 6 . The holding elements 6 lock the ends of the spring 2 in the radial direction and enable the usual spring preload to be applied. So the Fe of the 2 can be attached to the floating saddle 1 itself without any further processing.

In Fig. 2 ist eine Teilansicht des Schwimmsattels 1 aus Fig. 1 im Schnitt dargestellt. Man erkennt deutlich den abgewinkel­ ten Überstand 7 am Ende der Feder 2, der in eine Zurücksetzung 8 innerhalb der Ausnehmung 3 des Schwimmsattelschenkels 4 greift und dadurch die Feder 2 in axialer Richtung sichert. Dabei werden die Zurücksetzungen 8 beim Gießen des Schwimm­ sattels 1 angeformt und die abgewinkelten Überstände 7 durch Biegen der freien Enden einer heute üblichen Gehäusehal­ tefeder gewonnen. FIG. 2 shows a partial view of the floating saddle 1 from FIG. 1 in section. One can clearly see the angled th overhang 7 at the end of the spring 2 , which engages in a recess 8 within the recess 3 of the floating caliper leg 4 and thereby secures the spring 2 in the axial direction. The resets 8 are molded during the casting of the floating saddle 1 and the angled projections 7 are obtained by bending the free ends of a housing spring which is common today.

Fig. 3 zeigt eine Teilansicht des Schwimmsattels 1 im Schnitt von der Seite, die der Bremsscheibe zugewandt ist. Hier wird die Befestigungsweise der Feder 2 innerhalb der Ausnehmung 3 des Schwimmsattelschenkels 4 verdeutlicht. Der abgewinkelte Überstand 7 der Feder 2 hakt in die Zurücksetzung 8 der Aus­ nehmung 3 ein und fixiert die Feder 2 in ihrer axialen Posi­ tion. Radial wird die Feder 2 durch das blechartige Halte­ element 6 gesichert. Fig. 3 shows a partial view of the floating caliper 1 in section from the side facing the brake disc. The manner in which the spring 2 is fastened within the recess 3 of the floating caliper leg 4 is illustrated here. The angled projection 7 of the spring 2 hooks into the reset 8 from the recess 3 and fixes the spring 2 in its axial position. Radially, the spring 2 is secured by the sheet-like holding element 6 .
