Device for braking and / or for reversing the direction of rotation of a drive which can be driven by an electric motor drive component which can be driven.

摘要

The invention relates to a device (32) for the braking and / or for reversing the direction of rotation of a by means of an electric motor drive (34) rotationally drivable component (2), in particular of a rotor (2) of an electric motor (34) as a brake actuator of a vehicle, comprising at least the following features:a) an elastic spring means (6, 8), from which a support section (10, 12) is fixedly supported;b) a coupling device (18, 20, 22, 26), by means of which a coupling portion (18, 20) of the spring means (6, 8) with the rotationally drivable component (2) can be coupled or can be decoupled from the latter.c) in the case of a coupling device (18, 20, 22, 26) with the spring means (6, 8) coupled rotationally drivable component (2) whose rotational movements elastic deformations of the spring means (6, 8) to cause.
