The invention relates to a device for reducing low and high frequency contact force variations between a current collector of an electric traction vehicle having a bow and a catenary by regulating the contact force. In the area of the bow (10), an actuator (13) affected by a self-adjusting regulator is placed enabling direct or indirect transmission to the contact strip (11) of an actuating force dependent on the course of operation occurring in addition to a predetermined static pressure force and acting in opposite direction of the contact force variations.
L'invention concerne un dispositif servant à réduire les variations de force de contact basse et haute fréquence entre le pantographe supportant un archet d'un véhicule à traction électrique, et une caténaire par régulation de la force de contact. Dans la zone de l'archet (10), un actionneur (13) commandé par un régulateur à fonctionnement adaptatif permet de transférer directement ou indirectement à la bande de frottement (11) une force de pression qui est fonction de l'évolution du fonctionnement et qui vient s'ajouter à une force de pression statiquement prédéterminée. La force exercée par l'actionneur agit dans la direction opposée aux variations de la force de contact.
