    摘要: The invention relates to an electromechanical friction brake, for example in the form of a disc brake having an electromechanical actuation device. The electric motor of the actuation device presses a frictional brake lining against a brake disc by means of a reduction gearbox and a ball ramp mechanism. The actuation device is supported by a spring washer that is pretensioned so strongly that when the disc brake is released it acts on a segment with a falling spring characteristic; that is, a spring force exerted by the spring washer on the frictional brake lining increases with increasing tension of the disc brake.

    摘要: The invention relates to a self-boosting electromechanical friction brakes particularly in the form of a partially lined disk brake. The friction brake includes a friction brake lining which is helically movable with respect to the direction of rotation of a brake disk and pressed there into. A ramp mechanism is provided with ramps which cooperate with a roller bearing mechanism supporting the brake lining, to obtain the self-boosting effect. According to the invention, two of three rolls of the ramp mechanism are embodied with directing flanges for guiding the rolls on the ramps in order to helically guide the friction brake lining.
