Abstract
A braking device for an electric motor includes two brake pads, which are connected to brake disks, which cooperate with a brake rail. The two brake pads are rigidly connected by a connecting element, which is able to experience a certain deflection under the influence of a piezoelectric element, which is used to distance the two brake pads from each other. An assembly, which includes the two brake pads and their connecting element, is fastened on a support by a fastening device, which is elastically deformable along the direction at right angles with respect to the brake rail and to the two brake pads. The elastically deformable fastening device is formed of plates, which are connected on one end to the assembly and on the other end to the support.
