Abstract

A one-piece brake carrier for a vehicle disc brake is provided. The brake carrier has a frame-like disc wrap-around element which has two mutually parallel bridge struts, and two frame sections arranged parallel to a brake disc rotation axis and connecting the bridge struts. The brake carrier further has a securing flange by which the brake carrier is fixable to an axle flange. One or both of the frame sections, starting from a side of the brake carrier away from the securing flange widens toward an outer edge of the securing flange.

First claim

What is claimed is:

1. An integral brake carrier for a vehicle disc brake having a brake disc, comprising:
a disc-encompassing frame portion having two parallel bridge struts and two frame portions arranged parallel to a brake-disc axis of rotation and connected to the two bridge struts; and
a fastening flange configured for attaching the brake carrier to an axle flange of a vehicle axle,
wherein at least one of the two frame portions widen in a direction from a side of the disc-encompassing portion facing away from the fastening flange, to an outer edge of the fastening flange, the widening being an increase in distance from a plane of the disc-encompassing portion, and
at least one of the bridge struts is provided with at least one side planar surface tilted by an angle away from a right angle relative to a side facing the brake disk, wherein the at least one of the bridge struts has a portion with a trapezoidal shaped cross section defined in part by the at least one side planar surface.

2. The brake carrier as claimed in claim 1 , wherein the angle is on at least the bridge strut on the side that faces the fastening flange.

3. The brake carrier as claimed in claim 2 , wherein the angle on the bridge strut on the side that faces the fastening flange is on the upper side of the bridge strut, and the angle is tilted away from a horizontal plane which lies parallel to a plane of the base surface of the disc-encompassing portion.

4. The brake carrier as claimed in claim 2 , wherein
the angle on the bridge strut on the side that faces the fastening flange is on the lower side of the bridge strut, and
the angle is tilted away from a horizontal plane which lies parallel to a plane of the base surface of the disc-encompassing portion.

5. The brake carrier as claimed in claim 2 , wherein
the angle 1° to 20°.

6. The brake carrier as claimed in claim 2 , wherein
the angle 5° to 12°.

7. The brake carrier as claimed in claim 2 , wherein
the angle varies over a length of the bridge strut on the side that faces the fastening flange.

8. The brake carrier as claimed in claim 1 , wherein the brake carrier has two carrier horns on a side of the brake carrier that faces away from the fastening flange, and two carrier horns on a side of the brake carrier that faces the fastening flange, the carrier horns on the side of the brake carrier that faces the fastening flange are higher than the carrier horns on the side of the brake carrier that faces away from the fastening flange, the two carrier horns on the side of the brake carrier that faces the fastening flange each have an L-shaped cross section, the L-shaped cross section of the carrier horns on the side of the brake carrier that faces the fastening flange have an axial thickness greater than an axial thickness of the carrier horns on the side of the brake carrier that faces away from the fastening flange, the brake carrier has a reinforcement rib on the side facing away from the fastening flange which includes a central, curved rib portion, two rib portions having a rectilinear profile, and the central, curved rib portion and the two rectilinear rib portions form a closed contour line, the contour line of the reinforcement rib begins at one of the two frame portions and ends at the other of the two frame portions, the two rib portions having a rectilinear profile extend along the contour line parallel to, or in, a plane of a base surface of the disc-encompassing portion, the central, curved rib portion extends along the contour line with the bridge strut facing away from the fastening flange across a plane of symmetry of the brake carrier, the brake carrier has one or more apertures extending through at least one of the base surface and the reinforcing rib in a region adjacent to the carrier horns on the side of the disc-encompassing portion that faces away from the fastening flange, the one or more apertures are two apertures arranged mirror-symmetrically with respect to the plane of symmetry, a clear width of a brake pad slot formed between the carrier horns on the side that faces away from the fastening flange is greater than a clear width of a brake pad slot between the carrier horns on the side that faces the fastening flange, and at least one of the bridge struts has at least one constriction.

9. The brake carrier as claimed in claim 8 , wherein the at least one constriction is symmetrical about the plane of symmetry.

10. The brake carrier as claimed in claim 1 wherein the trapezoidal shaped cross section comprises a parallelogram shaped cross section defined in part by the at least one side planar surface.
