Abstract

A multi-disk brake for a motor vehicle has two multi-disk mechanisms and an actuation device for brake actuation and/or brake release of the multi-disk mechanisms, and an electric drive for translational actuation (spreading) of the actuation device, such as, in particular, the ramp unit. During a spreading operation, the multi-disk mechanisms are pretensioned in a metered manner by the actuation device and produce a desired frictional engagement, and a correspondingly reversed activation of the actuating mechanism enables a correspondingly metered brake release. By means of the electric drive, the action of the multi-disk brake can be metered overall in a particularly precise, sensitive and compensated manner in modern vehicle topology, including all peripheral brake components and systems, including recuperation.
