ABSTRACT:
An electromechanical brake has an element to be braked, at least one friction lining for frictionally engaging with the element, and an electric actuator for displacing the friction lining so that it frictionally engages with the element. A constructively and energetically improved electromechanical brake can be provided by a reversible energy accumulator functionally coupled to the electric actuator which interacts with a force multiplication device such that when the brake is actuated by the actuator, the stored energy is successively supplied to the force multiplication device with increasing actuation travel of the actuator and the device converts the energy in a set manner to an actuation torque that increases with increasing actuation travel of the actuator, the torque being transmitted indirectly or directly onto the friction lining. When the brake is released, a brake-inherent restoring force reacting upon the force multiplication device via the friction lining recharges the energy accumulator.
