Abstract
An electromechanical disk brake having a self-boosting by means of a ramp mechanism with an encapsulation to protect moving parts of the brake against becoming soiled. The friction brake lining has a three-point support with three roller bodies and thus is braced in a statically defined way, and a contate gear mechanism for actuating the disk brake, which is not vulnerable to positional tolerances and does not cause any axial forces.

1-13. (canceled)
In a electromechanical partial-lining disk brake with self-boosting, having an actuating device, having a friction brake lining, which for braking can be pressed by the actuating device against a brake disk, and having a self-booster, which converts a frictional force, exerted by the brake disk on the friction brake lining when the friction brake lining is pressed against the rotating brake disk, into a contact pressure which presses the friction brake lining against the brake disk, the improvement wherein the self-booster has a ramp mechanism;
- and wherein the ramps of the ramp mechanism have a helical course that is concentric to one another and at least approximately concentric to an axis of rotation of the brake disk and guide the friction brake lining, for pressing against the brake disk, both transversely to the brake disk (feed motion) and approximately in a circular arc in the circumferential direction to the brake disk.
