Abstract

A brake pad retainer is provided for a disc brake for a commercial vehicle. A pad retaining bracket is supported by pad retaining springs on both sides of a brake disc on a brake pad arranged in a brake caliper. The pad retaining bracket tensions a mounting opening of the brake caliper in the direction of the axis of the brake disc and is maintained at least on one side by a bolt-shaped securing element in a securing eye of the brake caliper. The brake pad retainer is designed such that the securing element is formed from an eccentric bolt having a shaft and at least one eccentric section which is positioned so that it is axially offset with respect the shaft.

First claim

What is claimed is:

1. A brake pad mount of a disc brake for a commercial vehicle, comprising:
a pad mounting bracket supportable on pad mounting springs of brake pads arranged on both sides of a brake disc in a brake caliper of the disc brake, wherein
the pad mounting bracket bridges an assembly opening of the brake caliper in an axial direction of the brake disc,
a bolt-shaped securing element that extends through a single transverse bore in a fastening socket of the brake caliper to hold the pad mounting bracket at least on one side, wherein
the bolt-shaped securing element comprises an eccentric bolt having a shank arranged in the single transverse bore, and at least one eccentric section positioned offset axially with respect to the shank,
a largest dimension between outer faces of the shank and the eccentric section is less than a diameter of the transverse bore of the fastening socket, and
the shank is pressed and automatically rotatable under spring pressure applied to the eccentric section via the pad mounting spring onto an upper inner surface of the transverse bore such that a longitudinal axis of the shank is below that of the eccentric section.

2. The brake pad mount according to claim 1 , wherein
a respective eccentric section is connected on each side of the shank, at least one respective eccentric section having a head on a side facing away from the shank.

3. The brake pad mount according to claim 1 , wherein the length of the shank corresponds to a length of a transverse bore through the fastening socket.

4. The brake pad mount according to claim 2 , wherein the head bears against a side face of the pad mounting bracket.

5. The brake pad mount according to claim 2 , wherein the respective eccentric sections lay in respective beads of the pad mounting bracket.

6. The brake pad mount according to claim 2 , wherein the respective eccentric sections cover associated edge regions of a transverse bore through the fastening socket.

7. A brake pad mount of a disc brake for a commercial vehicle, comprising:
a caliper having an assembly opening through which brake pads are arranged on both sides of a brake disc, the caliper having a fastening socket through which a single transverse bore is arranged;
a pad mounting bracket configured to be supported on pad mounting springs of the arranged brake pads, the pad mounting bracket being configured to bridge the assembly opening in an axial direction of the brake disc, the pad mounting bracket having an opening at one end through which the fastening socket of the brake caliper extends;
a bolt-shaped securing element configured to extend through the single transverse bore of the fastening socket in order to hold the pad mounting bracket, the securing element comprising an eccentric bolt having a shank and at least one eccentric section positioned offset axially with respect to the shank at one end of the shank, wherein
a largest dimension between outer faces of the shank and the eccentric section is less than a diameter of the transverse bore of the fastening socket, and
the shank is pressed and automatically rotatable under spring pressure applied to the eccentric section via the pad mounting spring onto an upper inner surface of the transverse bore such that a longitudinal axis of the shank is below that of the eccentric section.

8. The brake pad mount according to claim 7 , wherein the securing element comprises a second eccentric section connected to an opposite end of the shank and being position offset axially with respect to the shank.
