Title: Electromechanical wheel brake device

Abstract: The invention relates to an electromechanical wheel brake device with abrake caliper that is embodied of one piece with a gear housing in which aplanetary roller screw drive for pressing frictional brake linings againsta brake disk and a bevel gear pair for driving the planetary roller screwdrive to rotate are accommodated. In order to keep a ring gear free of aforce that acts axially on a nut of the planetary roller screw drive whenthe frictional brake linings are pressed against the brake disk, thedevice affixes a ring gear of the bevel gear pair in a rotationally fixedand axially mobile manner to the nut, for example by means of amulti-groove profile, and supporting the bevel gear with a separate axialbearing in the rigidly embodied gear housing.
