摘要:
The invention relates to a bearing for an angularly contacting bump stop, the washers of which consist of stamped sheet metal and have a surrounding geometry. The geometry of the bearing is such that, in every cutaway containing the geometrical axis of rotation (XX) of the bearing, the bottom bearing path forms a bottom circle arc (C
inf ) defining a bottom axial curvature center (O
inf ), and the top bearing path forms a top circle arc (C
sup ) defining a top axial curvature center (O
sup ), the bottom and top curvature centers being located on an angular geometrical axis (ZZ) that forms an angle of obliquity (Φ), of a value between 5° and 65°, with the geometrical axis of rotation (XX). More specifically, the bottom circle arc (C
inf ) has two ends defining an opening angle (φ
inf ) of a value greater than or equal to 80° and a tangent located in a bottom plane (P
inf ) perpendicular to the axis of rotation at a bottom tangent point (I
inf ) defining, with the nearest bottom circle arc (U
inf ) end, a portion of the bottom circle arc (C
inf ) having an opening angle (θ
inf I ) greater than or equal to 10°.
