Abstract

L'invention concerne un frein à disque électromécanique (1) pour véhicules automobiles avec un actionneur électromécanique (20), comprenant un moteur électrique (2) et une transmission (5) pour l'application d'un patin de frein (25, 25a), et un actionneur de frein de stationnement. Des actionneurs de frein de stationnement servent à empêcher un véhicule de s'éloigner d'un arrêt en roulant. Dans les freins à disque classiques, un cylindre de frein associé au frein à disque est habituellement équipé d'une fonction de frein de stationnement à actionnement mécanique. Dans le même temps, le principe de la fonction de frein de stationnement qui est utilisé dans un frein à disque classique ne peut pas être utilisé. Le but de l'invention est de fournir un frein à disque électromécanique doté d'un actionneur de frein de stationnement, ledit frein à disque étant peu coûteux et présentant une faible exigence d'espace d'installation. À cet effet, un frein à disque électromécanique comprend un actionneur de frein de stationnement qui est configuré en tant qu'entraînement linéaire électromagnétique (6) pour verrouiller le moteur électrique (2).
