Abstract
La presente invención se refiere a una unidad de posicionamiento (10) así como a un procedimiento para formar una conexión eléctricamente conductora entre una estación de carga estacionaria y un vehículo, en particular un autobús eléctrico o similar, en el que un contacto de carga eléctrica de la unidad de posicionamiento puede moverse con respecto a una superficie de contacto de carga (11) y ponerse en contacto con la misma mediante la unidad de posicionamiento, en la que la unidad de posicionamiento tiene un dispositivo de brazo articulado (12) y un dispositivo de accionamiento para accionar el dispositivo de brazo articulado, en la que el contacto de carga puede posicionarse entre una posición de contacto (37) para transmisión de energía y una posición retraída (36) para interrupción de energía por medio del dispositivo de brazo articulado, en el que el dispositivo de accionamiento tiene un accionamiento de ajuste (13) para formar una fuerza de ajuste que actúa sobre el dispositivo de brazo articulado y un dispositivo de muelle (29) que coopera mecánicamente con el accionamiento de ajuste, en el que puede formarse una fuerza de contacto que actúa sobre la superficie de contacto de carga mediante el accionamiento de ajuste, en el que el accionamiento de ajuste tiene un dispositivo de control y un motor eléctrico (43), que puede ser activado por el dispositivo de control, en el que el accionamiento de ajuste está diseñado de tal manera que un par de torsión del motor eléctrico puede ser detectado por el dispositivo de control, en el que la fuerza de contacto puede ser controlada por el dispositivo de control de acuerdo con el par de torsión del motor eléctrico.
