Patent ID: 6978868

Claim:
Electromechanical brake ( 10 ), especially for vehicles, comprising an electrical actuator generating an actuation force and acting upon at least one friction member ( 16 ) in order to press said member to elicit a friction force against a rotational component ( 14 ), which is to be braked, of the brake, and a self-boosting device arranged between the friction member ( 16 ) and the electrical actuator, said device servicing to self-boost the actuation force generated by the electrical actuator, and having at least one wedge ( 18 ) with an angle of inclination a that is supported on a corresponding counter bearing ( 22 ), characterized in that the electrical actuator has two drive mechanisms ( 34 , 34 ′) which act on the wedge ( 18 ) and can work against each other to generate the actuation force, and that in the range of low actuation forces, i.e. in a range tan α≅μ, where μ is the coefficient of friction between the friction member ( 16 ) and the component ( 14 ) to be braked, the two drive mechanisms ( 34 , 34 ′) work against each other to generate the actuation force.
