  • a coil spring which bears partly under bias on the outer circumference of the inner shaft and partially biased on the inner circumference of the hollow shaft. The frictional contact between the two shafts caused thereby causes the drive to be able to move the electric cable into or out of the bearing device. At least the drive is able to pick up the electric cable from a drum.
  • the slip clutch limits the tension that can be initiated by the drive in the electric cable in the event of such a fault. Conversely, prevents this coupling, which can be initiated by a manual pulling out of the electric cable at an increased speed, an excessively high tension in the electric cable
  • the clutch is a pinch roller freewheel clutch that can be coupled or decoupled by the drive.
  • a Sperrklinkenkupp- ment ie a clutch with at least one pawl which couples or decouples a drive shaft with an output shaft depending on the direction of rotation.
  • This embodiment which comprises a clamping roller freewheel coupling or a pawl coupling, is designed in particular such that the electric cable is manually pulled out of the bearing device. A drive is thus unable to cause the moving out of the electric cable from the storage device out or to transmit a correspondingly directed force to the electric cable.
  • the coupling is decoupled by rotating a drive-drivable shaft in the extension direction, that is opposite to the direction required for moving the electric cable into the bearing device. While pulling out, a user of the electric rochess thus no resistance by the drive and the bearing device rotates freely, as long as a user does not pull the electric cable out of the bearing device with such a high speed that the output overtakes the drive.
  • An allowable pull-out speed can be set by the rotational speed of the drive shaft, which can be indirectly or directly driven by the drive. As the rotational speed of the drive shaft increases, the speed with which the electric cable can be pulled out of the bearing device without being braked by the drive increases.

If the storage device comprises, for example, an interior in which the electric cable can be stored, then the cable guide is preferably arranged adjacent to the opening of the interior, from which the electric cable is brought out of the interior for pulling out.
  • the cable guide is pivotally mounted. A change in the tensile stress exerted on the electric cable can give away the cable guide. If an excessively high tensile stress occurs, the cable guide is thereby pivoted in such a way that the said switch is actuated.

  • the detector device can detect who is going below a predetermined minimum cable loading force. Such a predetermined minimum cable tensile force is in particular then fallen short of when the electric cable is not applied to the cable guide, and thus, for example, the cable guide is pivoted to a corresponding stop.
  • the control which is present in particular in the form of an electrical and / or electronic control unit, then preferably causes the electro-battery to be drawn in, ie moved in the direction of its stored position or traversed, or a transport in the extension direction is slowed down or stopped when the electric cable is to be pulled out. Retraction can be done, for example, by winding on a cable drum.
  • the rotational speed is preferably slowed down or stopped when a minimum pull-out force is undershot.

For example, a sagging of the electric cable, which could cause interference, is thus avoided.
  • another, effected by the drive or supported transport of the electric cable in the extension direction for pulling out by the controller is initially accelerated as soon as a predetermined cable pull force is reached. The comfort is increased so on. Only after reaching a maximum pull-out speed makes the slip clutch noticeable in this embodiment and decouples the drive from the electric cable.

Abstract

L'invention concerne un dispositif de stockage pour un véhicule électrique, comprenant un câble électrique qui peut être stocké au moyen de ce dispositif de stockage. Un dispositif de transport permet d'amener le câble électrique dans sa position de stockage. Ce dispositif de transport comprend un entraînement, de préférence un entraînement électrique, au moyen duquel le câble électrique peut être amené dans sa position de stockage. Le dispositif de transport comprend également un accouplement qui permet de transmettre au câble électrique une force générée par l'entraînement ou un couple généré par l'entraînement de manière à amener le câble électrique dans sa position de stockage au moyen de la force transmise ou du couple transmis. L'accouplement peut en particulier être désaccouplé au moyen de l'entraînement et/ou par retrait manuel du câble électrique du dispositif de stockage et/ou par blocage du câble électrique. Si l'accouplement a été désaccouplé, aucune force ne peut être exercée par l'entraînement sur le câble électrique, ou seulement une force nettement réduite (par rapport à la force maximale pouvant être transmise par l'entraînement au câble électrique). Cet accouplement est utilisé pour accroître le confort et/ou garantir un fonctionnement sûr même en cas de fausses manœuvres de l'utilisateur.
