摘要： The invention relates to an electromechanical brake (10), especially for vehicles, which comprises an electrical actuator (18) producing an actuation force and acting upon at least one friction member (21) in order to force said member against a component (21) of the brake to be slowed down, thereby eliciting a frictional force. The invention also comprises a self-energizing system arranged between the friction member (21) and the electrical actuator (18). Said system comprises a wedge arrangement (11) that serves to self-boost the actuation force produced by the electrical actuator (18). The aim of the invention is to simplify said system in terms of design and control technology. For this purpose, the actuator (18) has a single electric motor (24) and the actuation force produced by it is released via a spindle/nut arrangement (30) having a rotationally received, stationary spindle (26) and a rotationally fixed nut (28) that can axially travel on the spindle by rotating the spindle. Alternatively, the nut is received so as to be stationary and rotatable and the spindle is rotationally fixed and can axially travel. The spindle (26) is rotationally received by means of axially prestressed bearings (36, 38) and the nut (28) is mounted on the spindle (26) in a manner axially prestressed in relation to the spindle. The traveling movement of the nut (28) is transmitted onto the wedge arrangement (11) by means of a transmission element which is connected to the nut (28) and to the wedge arrangement (11) with zero backlash.
