Zusammenfassung:The utility model discloses an electro-hydraulic brake actuator of a novel pipeless electronic hydraulic brake system. The electro-hydraulic brake actuator comprises a hollow motor, a hydraulic mechanism and a piston brake caliper which are connected in sequence, a planetary speed reduction screw rod mechanism is rotationally mounted in the hollow motor; the planetary reduction screw rod mechanism comprises a screw rod and a piston nut which are in transmission connection; the screw rod is in planetary transmission connection with the hollow motor; the piston nut is slidably mounted in a hydraulic cylinder of the hydraulic mechanism; the hydraulic cylinder is hydraulically communicated with the piston brake caliper; the sliding of the piston nut is used for hydraulically controlling the clamping or loosening of the piston brake caliper; through cooperation of the hollow motor and the planetary speed reduction screw rod mechanism, the screw rod is rotationally installed in the hollow space of the hollow motor,
