Disc brake for a motor vehicle and housing for the same

摘要

The invention relates to a disc brake for a motor vehicle having a housing, a piston which is movable in the housing along a longitudinal axis and a nut-spindle arrangement which acts on the piston or can be brought into engagement with this, wherein the nut-spindle arrangement is arranged in the housing and is workingly supported via a bearing arrangement on a support surface of the housing. In order to increase the service life of the bearing arrangement, the support surface is formed by a defined contact surface which projects with respect to an adjacent housing region and against which the bearing arrangement bears.

1. Disc brake for a motor vehicle having
a housing, a piston which is movable in the housing along a longitudinal axis and a nut-spindle arrangement which acts on the piston or can be brought into engagement with the piston, wherein the nut-spindle arrangement is arranged in the housing and is workingly supported via a bearing arrangement on a support surface of the housing, wherein the support surface is formed by a defined raised contact surface which projects in an axial direction with respect to adjacent surrounding housing regions spaced both radially inwardly and radially outwardly relative to the defined raised contact surface and wherein the defined raised contact surface extends in a radial direction over a section of a housing region located between the adjacent surrounding housing regions and against which the bearing arrangement lies; and wherein the bearing arrangement comprises an axial thrust bearing configured to lie against the support surface with a bearing ring, wherein the bearing ring includes a first surface which lies directly against the support surface and an opposite second surface which lies directly against the bearing arrangement.
