Abstract

La présente invention concerne un dispositif de frein de stationnement électrique permettant à un véhicule de mettre en œuvre un câble de manœuvre relié à une unité de mise en œuvre de frein de stationnement, dans le sens du serrage comme dans le sens du desserrage. Ce dispositif de frein de stationnement électrique pour véhicule comprend un boîtier, une unité motrice, une plaque d'entraînement, une unité d'interblocage, un enclencheur-désenclencheur, un premier élément élastique, et un contrôleur. L'unité motrice, qui est placée à l'intérieur du boîtier, délivre une force motrice permettant d'actionner le câble de manœuvre dans le sens du blocage. La plaque d'entraînement, qui est placée dans le boîtier, est animée d'un mouvement de rotation par l'unité motrice. L'unité d'interblocage peut s'enclencher et se désenclencher sélectivement de la plaque d'entraînement. Lorsqu'elle est enclenchée, l'unité d'interblocage et solidaire en rotation avec la plaque d'entraînement de façon à actionner le câble de manœuvre selon le sens du serrage. L'enclencheur-désenclencheur établit et interrompt en force la liaison de la plaque d'entraînement avec l'unité d'interblocage. Le premier élément élastique assure les fonctions d'élasticité servant à actionner l'unité d'interblocage pour rappeler en position de desserrage le câble de manœuvre quand la plaque d'entraînement et l'unité d'interblocage ne sont pas enclenchées. Enfin, le contrôleur commande sélectivement le fonctionnement de l'unité motrice et de l'enclencheur-désenclencheur conformément aux signaux d'entrée.
