DETAILED DESCRIPTION OF THE DRAWINGS
FIG. 1 illustrates a disc brake, particularly for a utility vehicle, including a caliper 1, which has a receiving space 4 for an application device (which is not shown). The caliper straddles a brake disc. Brake pads 3 are movable into an operative connection with brake disc. (FIG. 1 showing only one brake pad 3). The caliper 1 is fastened to a vehicle-side brake anchor plate 1a.
A holding clip 5 is releasably fastened to the caliper 1. This holding clip 5 spans an insertion opening of the caliper 1 for inserting the brake pads and is used as a clamping device for springs 6, which upon the outer edges of the brake pads 3.
By means of its side facing away from the receiving space 4 for the application device, the holding clip 5 is fitted into a receiving device 7 of the caliper 1, while, by means of its other end, it is fitted onto a bolt 8 of the caliper 1 and is held by a securing device.
In the embodiment illustrated in FIG. 2, as well as in FIGS. 5 to 7, this securing device consists of a securing pin 9, which is fitted into a transverse bore 11 (FIG. 3) of the bolt 8, as well as of a securing plate 10 fastened to the securing pin 9.
In the embodiment of the securing element illustrated in FIGS. 6a and b, the securing plate 10 is fixed to the head of the securing pin 9 and extends essentially parallel to its longitudinal axis, while the free end is bent.
In the operating position, the securing plate 10 illustrated in FIG. 6a as a perspective view and in FIG. 6b as a lateral view rests against the face of the bolt 8, while the bent end area reaches behind the bolt, so that an axial securing of the securing pin is ensured.
As illustrated in the embodiment of FIG. 7a (also perspectively) and of FIG. 7b (as a lateral view), the securing plate 10 has a passage opening 13, which is penetrated by the bolt 8 and whose diameter corresponds approximately to the diameter of the bolt 8. The operating position of this embodiment is visible in FIGS. 2 and 5. While the bent end area of the securing plate of FIG. 6 points in the direction of the securing pin 9, it has an opposite orientation in the example of FIG. 7.
FIGS. 8 and 11 also show securing devices which can be fitted into the transverse bore 11 of the bolt 8. These also consist of a securing pin 9 and, in the embodiment illustrated in FIG. 8, of a ring 14 connected therewith which, after the insertion of the securing pin 9 into the transverse bore 11, is placed over the bolt 8, so that hereby also an axial securing of the securing pin 9 is ensured.
The securing element according to FIG. 11 is constructed as a securing clip 17 which also has a securing pin 9, which can be fitted into the transverse bore 11 and is adjoined by one spring leg 18, respectively, on the right and the left. This spring leg 18 is provided with a bulge 19 in which the bolt 8 rests under the spring tension of the spring leg 18 after the securing pin 9 is slid into the transverse bore 11. The securing clip 17 may be formed of two mirror-symmetrical wire parts, of which two straight mutually connected legs form the securing pin 9. FIG. 11a is a lateral view and FIG. 11b is a top view of the securing clip 17.
FIGS. 9 and 10 finally show securing elements in the form of a snap ring 15 (FIG. 9) and a securing ring 16 (FIG. 10), respectively. These can be inserted into a ring groove (FIG. 4) of the bolt 8, when the holding clip 5 is fitted on, so that an axial securing of the holding clip 5 on the bolt 8 is ensured.
