A method and an arrangement for controlling cable winding and unwinding in an electrically driven vehicle. In the method, cable winding and unwinding, respectively, are controlled on the basis of the position of driving and/or steering means of the vehicle. The arrangement comprises only one unwinding valve (7) connected in series with a hydraulic motor (4), by which valve the counterpressure of the hydraulic fluid flowing through the hydraulic motor (4) can be regulated during cable (2) unwinding from the reel (1), and one winding valve (6) respectively, by which the quantity of the hydraulic fluid coming to the hydraulic motor (4) can be regulated during cable (2) winding.
L'invention concerne un procédé et un appareil pour réguler l'enroulement et le déroulement d'un câble d'un véhicule à moteur électrique. Le procédé repose sur l'utilisation de la position du moyen moteur et/ou du moyen de guidage du véhicule pour réguler l'enroulement et le déroulement du câble. L'appareil comprend une seule vanne de déroulement (7) reliée en série à un moteur hydraulique (4). Cette valve permet de réguler la contre-pression du fluide hydraulique passant dans le moteur hydraulique (4) durant le déroulement du câble (2) de la bobine (1). Une vanne d'enroulement (6) permet de réguler la quantité de fluide hydraulique arrivant au moteur hydraulique (4) pendant l'enroulement du câble (2).
