Electromechanical brake actuator for a vehicle brake

An electromechanical brake actuator (10) for a vehicle disc brake (1) of a vehicle (100), the electromechanical brake actuator comprising:

• a brake tappet (14) that moves substantially translationally and transmits a compressive force (F) in the direction of a brake pad (6, 6′),
• a drive member (16) that generates a drive movement (A), and
• a coupling gear (18) that operatively connects the drive member (16) and the brake tappet (14) to one another;
• wherein the coupling gear (18) converts the drive movement (A) of the drive member (16) into an adjustment movement (B) of the brake tappet (14),
• wherein the coupling gear (18) has a coupling member (38) which is in contact with the brake tappet (14),
• wherein the coupling member (38) is guided movably along at least one cam path (40, 60) and converts the drive movement (A) of the drive member (16), which acts on the coupling member (38) at a substantially uniform drive speed (A′), into an adjustment movement (B) of the brake tappet (14) at an adjustment speed (B′) which is non-uniform in portions.
