  • Patent number: 11732763
    Abstract: A ramp actuator has a pivotable ramp disc, which on a first end face has at least one ramp, which is prepared for the rolling of a rolling body and, spaced apart therefrom, has a raceway for bearing rolling bodies of a rolling bearing prepared to receive radial and axial forces. A bearing ring can be fixed on a shaft, wherein the ratio of the axial width of the ramp disc relative to the support height thereof is between 2.9 and 4.1 and the ratio between the ramp radius of the ramp of the ramp disc relative to the support height of the ramp disc is between 0.7 and 1.3. A method for producing a ramp disc for such a ramp actuator includes drawing, upset forging and embossing, preferably carried out in that order.
