An actuation unit for an electromechanically actuated disk brake for motor vehicles, arranged on a brake caliper (50) in which two brake linings (4, 5) interacting with lateral faces of a brake disk (6) are displaceable, one of the brake linings (4) being engageable by the actuation unit directly with the brake disk (6) by means of an actuating element (7). The actuation unit including an electric motor (1) and a reduction gear (2) operatively arranged between the electric motor (1) and the actuating element (7) and having a threaded spindle (17) which is driveable by the electric motor (1) and bears axially against the brake caliper (50). A rolling element bearing (33, 42, 63) and a force measuring device (30, 40, 60) having a deformable element (35, 43, 65) which is deformed when subjected to the force to be determined are arranged in the force flow between the threaded spindle (17) and the brake caliper (50). The threaded spindle (17) bearing against the deformable element of the force measuring device (30, 40, 60) via the rolling element bearing (33, 42, 63). |
